INTRODUCTION
This manual describes how to use Tekscan’s T-Scan III Computerized Occlusal Analysis. T-Scan III is a reliable and
easy-to-use clinical diagnostic device that senses and analyzes occlusal contact forces using paper-thin, disposable
sensors. The T-Scan III system comes with a full-featured Patient File Management system, which makes storing patient
records and tracking occlusal recordings simple, and makes the system an integral component of the clinical
workstation for occlusal diagnosis and treatment.
The T-Scan III software offers features that allow the user to:
•
•
•
Record the patient’s occlusal contact data
View the patient’s tooth contacts and associate them with specific teeth
Analyze the data, with the force and time relationships of the contacts displayed as color contour images
showing:

•
Instant IP
Center of Force
Center of Force Trajectory
More advanced features, such as: Max, Delta, Graph, Graph Zoom and 3-D Columns
Manage patient records and movie files through the use of an intuitive database
The T-Scan III system is comprised of the Microsoft (MS) Windows-based T-Scan III software, the associated
hardware, and patented Tekscan sensors. The system’s versatility allows you to copy occlusal contact data (as an image
or text file of actual force percentage values) and paste it into other Windows applications, or to print this information
to any of the hundreds of Windows-compatible color or grayscale printers.
This manual provides a thorough description of the system’s features and capabilities. Follow the Quick Start section as
a guideline, and refer to specific sections for more detailed instructions on how to use each feature.
CLINICAL APPLICATION
The T-Scan III technology has application in all phases of dentistry in which occlusal diagnosis and treatment are
involved, and remains the only practical quantitative method to analyze the occlusion.
The analytical software displays, such as "Center of Force (COF)" and "Center of Force Trajectory," provide in-depth
understanding of the overall balance of the occlusion, which cuts to the heart of occlusal analysis. Center of Force
analysis allows the dentist to examine the total effect of restorative dentistry on the patient’s maximum closure and
excursions, and is as easy as the click of a mouse.
Other features, such as instant "IP" and "Max," summarize critical occlusal data and give the dentist valuable assistance
in the diagnosis and treatment planning of occlusal disease, such as trauma caused by transient forces and interceptive
contacts. T-Scan III also uses subtractive technology, as shown in the "Delta" feature, to isolate slides and other
pathology from the occlusion, providing previously unavailable information.
Since the introduction of the original product in 1987, the use of computerized occlusal analysis has gained importance
in implant dentistry, patient education, and complex restorative and TMJ diagnosis and treatment.
It is clear that access to occlusal force and time data is critical to the discerning clinician, whether he or she is doing
something as complex as tracking the changing forces on implants in relation to natural teeth, or simply perfecting the
occlusion on a bite guard. T-Scan III has a wide range of clinical applications and, because of this, Tekscan provides
T-Scan application guides to assist the T-Scan operator. These application guides automatically install to the desktop
in a folder called “Manuals” when loading the software.

For many practitioners, patient education is the most important application of the technology. The T-Scan III software
displays make occlusal problems easily understandable, increasing patient involvement and treatment acceptance. TScan III provides a valuable source of previously unavailable information, which can become a permanent part of the
patient’s record.
QUICK START
Welcome to Quick Start! This section is a quick look at how to use your T-Scan III system, and is intended to get you
started using your system in just a few easy steps. This Quick Start procedure should be followed as a general outline; it
will give you the basics on how to view tooth contact data in a Real-time window, record this data, play the recording
back, and analyze the occlusal information. However, it is highly recommended that you read the entire manual before
using the system in a patient test.
Note: You must read the entire manual before performing any tests, as this only provides general
guidelines.
Note: Familiarity with MS Windows is assumed.
Note: This procedure assumes that the proper hardware and software has been successfully
installed on your system (refer to the Installation section).
The following outlines the proper procedures to take a basic recording with your T-Scan III system:
1. Make sure that the T-Scan III software has been successfully installed on your system, and the sensor support
and sensor are correctly inserted into the Evolution or USB handle. The handle must be plugged into the
computer, and recognized.
2. Double click the shortcut icon that has been placed on your desktop, or click on the Start button at the bottom
left of the screen, select Programs, and then click the T-Scan III icon to run the program.
3. The Main window opens with the Patient List.
4. In the Patient List ("Patients" dialog), click New Patient. A new Patient Record is opened , along with the Arch
Table. Enter the new patient’s information (at a minimum, you must enter the patient’s first and last names).
Ensure the central incisor width is correctly entered, so that embrasure lines are approximately representative
of the patient’s bite. Refer to the Adding a New Patient to the System section for further information.
5. Click the New Movie button in the Patient Record. A blank Real-time window appears for the new patient.
The left side of the Real-time status bar should display "Sensor OK." If the sensor is not aligned correctly, the
message displays "MISALIGNED!" and the program prompts you to “Please insert a sensor into the handle”. If
you get this message, remove and reinsert the sensor into the handle, ensuring that the sensor is right side up,
and the handle latch is completely down. If the "Sensor OK" message still does not appear, consult the
Troubleshooting section.
6. Place the sensor in the patient’s mouth, with the sensor support pointer between the two central incisors. Keep
the handle as parallel to the occlusal plane as possible.
7. Press the Record Start & Stop button on the handle. Wait for your computer to “beep.” This means the system
is ready to record. If your computer does not have sound, or you do not hear the beep for some reason, look at
the bottom of the Real-time window; the system is ready to record if the status bar displays "Rec. Frame 0 of
300".

8. Have the patient bite down normally on the sensor. The first tooth contact causes the system to begin recording
(refer to the Recording Occlusal Data section for details). While recording is in progress, the Real-time Status
Bar displays the frame count progress.
9. When the correct number of frames have been collected, recording automatically stops. If you want to manually
stop recording before this time, press the Record Start & Stop button on the handle once again. The recording
stops.
10. As soon as recording is completed, the Real-time window becomes a 2-D Movie window, which is divided into
two equal colored boxes (one green for the left side and one red for the right side) around the mid-sagittal
plane. A 3-D Movie window, Graph window and Graph Zoom window are also automatically opened for the
current movie. The Graph and Graph Zoom windows contain color-coded "traces" representing the forces
inside each of the colored boxes in the 2-D Movie window.
The recorded occlusal data can now be reviewed and analyzed. To review the recording, use the movie controls
on your toolbar. Refer to the Reviewing a Recording section for further information.
11. To save your movie as a file that can be opened later, select Save Movie from the File menu. The newly
recorded movie is automatically named using the patient’s first, last and middle names. Refer to the
Autonaming section for further information.
The movie is then saved into the patient’s folder in the "C:\TScan\Database\Movies" directory. The file is saved
as a T-Scan III "movie" file (extension *.fsx).
When you save a movie, you are asked whether or not you would like the movie to be part of the database.
Refer to the Using the Patient File Management System section for more information.
12. You may now analyze the recorded data. The following View menu options are essential for the analysis of
occlusal forces:
•
•
COF (Center of Force)
& COF Trajectory
Add Line
•
IP (Intercuspal Position)
•
Delta
•
MAX (Maximum Cumulative Force)
•
Arch Model
Note: Refer to the Analyzing Occlusal Force Data section for a detailed description of each option.
13. Copy the force data from the Movie or Graph window. To do this, select Copy from the Edit menu. Alternately,
you can hover your mouse over a window and right-click to select Copy. The active window is copied to the MS
Windows clipboard as both text and an image (bitmap) that can be pasted into other Windows programs. Refer
to the Copy & Export Options section for more information.
14. To print the active window, first select Print Setup from the "File" menu and choose your desired Print Setup
options. When your options have been selected, click OK. Next, Select Print Preview from the "File" menu to
review the printed output display. If you are happy with the results, click the Close button, and then select Print
from the "File" menu. Finally, click OK in the "Print" dialog. The active window is printed. Refer to the Printing
section for more details.
You have completed the Quick Start section. You should now be familiar with T-Scan III, and see how easy it is
to view, save, and analyze the occlusal forces on the sensor. The rest of the manual gives you detailed
instructions on how to use the system.

SENSORS
The T-Scan III sensor is an ultra-thin (.004", 0.1 mm), flexible printed circuit that detects your patient’s occlusal
forces. These sensors are made up of 1370 active pressure sensing locations for the large sensor (#2001), and 1122
pressure sensing locations for the small sensor (#2501). These sensing locations are referred to as ‘sensing elements’,
or ‘sensels’. The ‘sensels’ are arranged in rows and columns on the sensor. Each sensel can be seen as an individual
square on the computer screen by selecting the 2-D display mode. The output of each sensel is divided into 256
increments, and displayed as a value (raw sum) in the range of 0 to 255 by the software.
The following shows the small (left)
and large (right) T-Scan Sensor:

Note: Sensor supports are not interchangeable. The small support must be used with the small
sensor, and the large support with the large sensor.
Maintenance and Care
• The same sensor should not be used on different patients. You may use the same sensor on the same patient
across multiple sessions, however those sensors should also be disinfected with a 70% Isopropyl Alcohol
solution after each use. To do this, slightly dampen a cloth with the alcohol solution, careful not to soak or
saturate the cloth. Then wipe the sensor.
• Sensors should always be stored flat in either the envelope in which they were shipped, or some other
protective cover. Improper storage can adversely affect sensor life.
• Sensor Replacement/Disposal: Always dispose of sensors in accordance with Federal and State guidelines
pertaining to medical biohazardous waste.

SOFTWARE
The T-Scan III software is compatible with Microsoft (MS) Windows 2000/XP/Vista. This section is an overview of the
components that make up the software.
MAIN WINDOW
When you start the T-Scan III program, the Main Window is displayed on your computer screen. The Main Window
consists of the Title Bar, Menu, Toolbar, and Main Status Bar. The Main Window may also contain one or more Realtime Window(s), Movie Window(s), Graph Window(s), and Legend. The window that is selected is considered the
active window. Only one window (Movie, Real-time, Graph, or Legend) can be active at one time, and the title bars of
the other windows will be grayed out. In the image below, the 2-D Movie Window is the active window because its title
bar is blue, while all other title bars are gray. The Main Window, and its components, are shown in the figure below.
TITLE BARS
Each window (Main, Real-time, Movie, Graph, and Graph Zoom) has a Title Bar along the top, which displays the
name (title) of that window (e.g. "Real-time 1" or "Movie1.fsx") and the patient’s name. If that window is paused,
"(Paused)" is added to the title. If a recording is in progress, "(Rec)" is added to the title. If the movie has been marked
by procedure, the Title Bar will show the procedure name (e.g. “protrusion”).
The following shows the Title Bar for a 2-D Movie window.
08/01/07
T-Scan III User Manual (Rev L)
21
Each Title Bar has the usual MS Windows control button at the left end, and Minimize, Maximize and Close buttons at
the right end (see figure above). Only one window may be active at any one time; the active window’s title bar is blue by
default, while any de-activated windows’ title bars are gray by default (though these colors may be different if you
changed your MS Windows desktop color schemes).
MENU
The Menu provides the pull-down menus used to control the T-Scan III program. Each Menu Bar option is described
in detail in the Main Menu section.
When no Movie or Real-time windows are open, the Menu Bar contains only the File, Options, and Help menus (see
figure below).
Some menu items contain shortcuts that can
be used on the keyboard. For example, in the
image at right, the Play Forward command
can be accessed by pressing Ctrl+F or F5 on
the keyboard. This will play the movie forward,
and may be easier than accessing the
command with the mouse. In addition, some
menu items may contain an arrow at the end of
the command. This indicates there is a submenu with additional commands available. In
the image below, hovering the cursor over the
Play Speed command opens a submenu with
additional Play Speed options.
Some menu items have an ellipsis (...) after
the command. This indicates additional
command parameters must be filled out in
order for the command to function. In this
case, clicking on the command will open a
dialog where these parameters can be input.
For example, in the image at right, the Arch
Parameters command requires additional
input from the user. Clicking on this
command opens the "Arch Parameters"
dialog where this information can be
entered.
TOOLBAR
Most T-Scan III functions can be performed using the Toolbar. The Toolbar provides most of the same options as the
Menu, but with icons replacing pull-down menus. Most icons on the Toolbar have a corresponding pull-down item in
the Menu; however, only the most frequently used items on the Menu Bar have an icon on the Toolbar.

T-Scan III User Manual (Rev L)
22
Note that not all Toolbar functions are available at all times. When a function is unavailable, it
will be "grayed out." The following displays the Toolbar and all associated icons.
There are optional commands that can be added and removed from this standard Toolbar (under Options -> Set User
Preferences -> "Toolbar" tab).
The following image displays these optional Toolbar items. Items in black are default icons and cannot be removed
from the Toolbar. Items in blue are default icons, but can be hidden by unchecking them in the "Toolbar" tab above.
Items in red are optional, and can be added to the Toolbar by checking them within the "Toolbar" tab above.

T-Scan III User Manual (Rev L)
23
The Toolbar can be relocated (separately) in the Main Window by clicking and dragging the edge of the Toolbar with
the mouse (anywhere outside an icon location). Release the mouse to place the Toolbar on another screen location
(shown below). To dock the Toolbar back in its original location, click and drag the Toolbar with the mouse and drop
it on top of the Menu along the left edge of the screen.
If you place the cursor on an edge of the Toolbar, a two-way
arrow will appear, and it’s shape and size can be changed (shown
at right).
The Toolbar can be hidden (disabled)
or displayed (enabled). To hide the
Main Toolbar, access the "Toolbar" command from the "View" menu (shown at left).
The Toolbar can be toggled on and off by clicking this menu item. When the Toolbar option is enabled (and the Main
Toolbar is visible), it will have a checkmark beside it in the pull-down menu.
Toolbar enabled (default - checked). The Toolbar is visible.
Toolbar disabled (unchecked). The Toolbar is hidden.
Note: The 2-D and 3-D Movie window Toolbars are unaffected by this command.

MAIN STATUS BAR
The Main Status Bar provides information about what is happening on your screen at any given moment. When the
cursor is over a Toolbar icon, the left side of the status bar will give a description of that icon; otherwise, it indicates
"Ready".
The image at right displays the main Status Bar indicating the sensor is ready.
The image at left displays the main Status Bar when the cursor is
located over an icon on the Toolbar. A "Tool Tip" is displayed under
the cursor location, and the Status Bar explains the function of the
icon.
When the mouse cursor is over a Real-time or Movie window, the right side of the
main Status Bar will give the cursor position ("Row, Col:"), and the pressure
("Load") on the sensor at that point (see image below). This "Load" display is
helpful if you want to know the exact pressure at a point, instead of just the
pressure range shown by the Legend.
Note that the cursor position corresponds to the actual row and column on the sensor (the origin,
or zero point, is the top left corner of the movie or real-time window).
REAL-TIME WINDOW
The Real-time window displays the sensor’s color-coded tooth
contact data as it is happening, or in real time. If no pressure is
on the sensor, a blank Real-time window will appear (shown
below). The T-Scan III software provides numerous options for
displaying, recording and analyzing the real-time data.
A Real-time window can be opened by clicking the "New
Recording" icon on the Toolbar, or by selecting New Recording
(under the "File" menu). Alternately, clicking the New Movie
button in an open Patient Record also accesses a new Real-time
window.

CR (Centric Relation) Recording Mode: When this mode is in effect, the Real-time window uses the CR Mode
recording settings ("CR recording time" and "CR Sensitivity") in the "Recording Settings dialog (Options ->
Recording Settings) to record occlusal data; otherwise, the Real-time window uses the standard IP mode
settings ("IP recording time" and "IP Sensitivity") to record occlusal data. Refer to the Recording Settings
section for information on how to change any of these settings. Refer to the CR (Centric Relation) Mode section
for more information about CR Mode.
Real-time Window Status Bar
The Real-time Window Status Bar is located at the bottom of the Real-time window, and displays the "sensor status" (or
the "frame count" of a recording in progress), and the "contact force." The sensor status is displayed (on the left side)
as either "Sensor OK" or "MISALIGNED!" If the message is "MISALIGNED!" this usually indicates the sensor is not
properly inserted into the sensor handle. Refer to the Troubleshooting section for advice on how to rectify this situation.

well as the forces inside the two equal
colored boxes in the active Movie
window (green for left side and red
for right side – see image at right).

A vertical solid black time line marks the elapsed time, and current movie frame, at which the force percentages inside
the two colored boxes in the 2-D Movie window are being displayed. A graph window is automatically displayed when
you record a movie or open a previously recorded movie. In order to view the graph, the user must select Graph from
the "View" menu, or click the Show Graph icon on the 2-D Movie window Toolbar to display a graph for the active
Movie window.
To show or hide the Graph display,
click "Graph" from the "View" menu.
Alternately, the user can click the
"Show Graph" icon on the 2-D Movie
window Toolbar.
To the right of the Graph in the window, the name of the corresponding Movie window is displayed, followed by the
actual force percentage values. If the information on the right side of the Graph window is not fully visible, this area can
be expanded by dragging (with the cursor) the line that separates it from the actual graph. Refer to the Analyzing
Occlusal Force Data section for more information on the T-Scan III Graphing features.

GRAPH ZOOM WINDOW
The Graph Zoom acts as a secondary graph which displays a
zoomed-in view of the Main Graph window. The Graph Zoom
cannot be enlarged or reduced in size and is permanently fixed to
display 1.5 seconds of the main Graph window. As most occlusal
force activity occurs and is captured in a very short duration of
time with a lot of activity, it is sometimes difficult to view the
subtle nuances that occur in the Graph window. This is where the
Graph Zoom can be useful to display activity down to the
millisecond. It provides a high resolution view of activity that is
occurring within the main Graph during this short duration.
Moving the black time line in either direction within the Graph window dynamically updates the time line in the Graph
Zoom window. This aids the user to target and hone in on a specific area of the Movie. Think of the Graph window as a
large scale map of the Movie, and the Graph Zoom is the smaller Inset map which displays a detailed view of a specific
area of the Movie.
Refer to the Graph Zoom section for further information about the Graph Zoom features.

LEGEND (COLOR SCALE)
The Legend is a segmented force color scale, which shows the range of colors
displayed in any open Movie or Real-time windows, and their associated nominal
forces. Differences in occlusal force in these windows can be distinguished by the
colors ranging from red (highest forces) to blue (lowest forces). All windows that
are open simultaneously will be controlled by one legend, making it very easy to
make comparisons between windows. The Legend’s key does not have any units. A
legend can be placed in the Main Window by selecting Set Legend from the
"Options" menu, or by clicking the corresponding Toolbar icon.
You can adjust the legend settings by sliding either of the two pointers, which allow
you to alter the colors displayed in the view window. Dragging the small triangles to
the right of the color scale upward or downward makes adjustments to the Legend. If
the lower triangle is moved up, all sensed forces below the level of this triangle will not be displayed. This feature can be
used to suppress the display of low-level noise, which may be distracting. If the upper triangle is moved down, the full
range of colors will be displayed for the resulting compressed range. In cases where the sensed forces are at the lower
end of the legend scale, this has the effect of increasing the color range of the display. All view windows dynamically
update as you slide a pointer. The legend settings are saved
until you exit the T-Scan III program.
If the Legend's upper or lower limit is changed, the center of
the Movie window Status Bar displays a flashing red and white
icon that warns the user of changes to the Legend's
parameters. In addition to this visual indicator, the legend icon
on the Toolbar and the Legend's color indicator also flash
simultaneously on-screen.
The image at right displays the areas of the screen
that flash if the Legend's upper or lower limits are
changed.
Note: Changing the legend settings only affects the
view within the Movie windows; it does not affect
the data in any way.
When you click the right mouse button while the cursor is over a Legend, the following additional options become
available:
•
•
•
Move: If you select Move, a four-way arrow appears, and the arrow keys (on your
keyboard) can then be used to move the Legend in the window. Simply selecting the
Legend's Title Bar with the cursor and dragging it to another location in the window can
also move it.
Close: Select Close to remove the Legend from the window.
Copy: If you select Copy, the Legend will be copied to the MS Windows clipboard. By
selecting Edit -> Paste or Paste Special, the Legend can then be pasted into other
Windows applications.
Note: in order to access this context-sensitive menu, the cursor must be located in the
space outside the legend area, but inside the legend window (as shown in the image at
right).

SMART DOCKING
Every time a 2-D Movie window is opened, its related windows are also automatically opened (3-D Movie window,
Graph window, and Graph Zoom window. By default, when a 2-D Movie window is opened, these 3 other related
windows are docked (snapped or glued) to the 2-D Movie window. This is known as Smart Docking.
Both the 2-D and 3-D windows are the master windows, while the Graph and Graph Zoom windows are the slaves.
Moving the 2-D or 3-D Movie windows also moves the corresponding Graph and Graph Zoom windows, so that the
connection is not broken. However, if the Graph or Graph Zoom windows are moved, the 2-D and 3-D movie windows
(masters) are not. The following illustration will help to clarify:
The master / slave relationship means that moving the 2-D or 3-D movie windows (shaded in blue)
also moves the Slave windows (Graph and Graph Zoom shaded in yellow). But moving the Graph or
Graph Zoom windows does not move the 2-D or 3-D movie windows (masters).
The same master/slave relationship exists between the Graph and Graph Zoom windows. The Graph window is the
master (moving it also moves the Graph Zoom window), while the Graph Zoom window is the slave (moving the Graph
Zoom window does not
move the Graph window).

Global Smart Docking
If multiple 2-D movies are open on-screen, you can disable
Smart Docking for all windows at once using the menu

windows.
Smart Docking: Graph Windows
The Graph and Graph Zoom windows are "docked" to the 2-D Movie window by default. This means that when a 2-D
Movie window is moved from one location to another on-screen, the Graph or Graph Zoom window moves with it. To
disable this feature, right-click on an empty area of the Graph or Graph Zoom window. A context-sensitive menu opens.
Select Disable Smart Docking. When disabled, the Graph or Graph Zoom window moves independently of the other
windows on-screen.

AUTOMATIC WINDOW CONFIGURATION
The 2-D movie window is the Master window for all others. This means that moving it also moves all other windows. It
also has a special status, in that if you move it too far to the edge, the program is smart enough to realize your other
windows will run out of room and automatically moves the two windows closest to the edge to the opposite side of the
2-D window. In this way, the windows cannot run out of room. Note that even though moving the 3-D Movie window
does move the 2-D Movie window (as well as the Graph and Graph Zoom windows), this will not cause any other
windows to move opposite the 3-D Movie window automatically. The following images will help to clarify:
In this image, the 2-D Movie window is moved (by clicking and dragging the Title bar) from the
right to left edge of the Main window. Notice how the 3-D Movie window and Graph Zoom window
are located on the left side of the 2-D window.

As it approaches the edge and obscures the 3-D and Graph Zoom windows, they are automatically moved
to the right side of the 2-D Movie window, providing more space so they can clearly be viewed.
The same relationship occurs with the Graph window and Graph Zoom window. When moving the Graph window
towards an edge (and obscuring the Graph Zoom window), the Graph Zoom window is moved to the opposing side.
Note that moving the Graph Zoom window does not move the Graph window automatically, and therefore, the Graph
window is never automatically moved.
MULTIPLE MODE
Multiple mode can be accessed via the View menu or as a toggle button on the main toolbar. With this mode turned on,
two or more Movie or Real-time windows can be opened on-screen simultaneously. If this option is turned off, only one
Movie or Real-time window can be open at any one time (Single mode). Attempting to open a
second movie closes the first movie before opening the second. Multiple mode is useful and
should be turned on (checked) if the user wishes to review more than one movie at a time.
Turning this mode off (unchecked) is useful if the user does not wish to review multiple
movies at once, and reduces clutter on-screen. The default state for this toggle button is
disabled (Single mode).
Note: Even with Multiple mode disabled, you can still select multiple movies to open via the
Patients dialog. However, only the first selected movie opens. To open multiple movies, first enable
Multiple Mode, and then select multiple movies to open using the Patients dialog. Refer to Using
the Patient File Management System for more information.
When Multiple mode is in effect, the last save made to the movie windows (before exiting) saves the size of the windows.
When those saved movies are later re-opened in multiple mode, they will appear on-screen with the same size. This
feature helps when comparing multiple movies side by side by providing a remembered on-screen appearance.

Edit Menu
The "Edit" menu contains options that relate to changes for the
current movie. Two main options are located on this Toolbar:
Copy and Comments. Each are outlined below.
Copy: Saves all, or a selected area of, the currently active Movie, Real-time, Graph, or Graph Zoom window to the MS
Windows clipboard as an image (bitmap). At the same time, text information relating to the window, such as the
window name, date and time, sensor information, time between frames, units and the contents of the comments fields is
also transferred to the clipboard. To paste this information into another Windows document, select Edit -> Paste
Special in that application, and then select either "bitmap" (graphic) or "text" to place it in the correct form.
The Copy option can also be found in the Context-Menu by clicking the right mouse button
while the cursor is over a Real-time, Movie, Graph, or Graph Zoom window. Refer to the
Analyzing Occlusal Force Data section for more information on the Copy menu item, as well
as other available Copy options.
The Copy command found within the context-sensitive menu when rightclicking over a Movie window (see image at right).
Note: For further information on how to export information from Tekscan
software into other software applications, please refer to the Copy & Export
Options section.
Comments: Opens a dialog box that allows you to view, add, and edit the comments
associated with the active Movie or Real-time window. The comment fields can be filled in
before a recording is taken (i.e. in a Real-time window), between recording and saving, or after saving. The
"Comments" dialog also displays the information from the Patient Record (i.e. Name, Patient ID, Gender, Date of Birth)
for easier movie identification and record keeping.
08/01/07
T-Scan III User Manual (Rev L)

If a Movie window is active, you may enter information in each field, but cannot change the field names. Once
comments have been added or altered in a Movie, the recording must be saved again in order to save these comment
changes.
If a Real-time window is active, the user can enter information in each field, and also add, delete, and change the field
names. Once comments are changed in a Real-time window, they are remembered until New Patient is selected from
the "File" menu, or the T-Scan III program is closed. If this Real-time window is recorded and saved as a movie, the
window’s comments are also saved. If the field names are changed and saved in a newly recorded movie, any later
recordings are automatically updated with these field names.
The Comments option can also be selected by clicking the right mouse button while the cursor is in a Real-time or
Movie window, and selecting Comments, or by accessing the "Comments" tab in the "Settings" dialog (under the
"Options" menu).
Right-clicking over a Movie window opens a
context-sensitive menu, where "Comments"
can be accessed.
Another way to view Comments for a Movie is going to
"Options -> Settings" and selecting the "Comments" tab.
Refer to the Including Comments with a Recording section for more information.
View Menu
The "View" menu items and corresponding Toolbar icons control the primary T-Scan III display and analysis
functions. When any of these View options are selected, it affects all open windows. Press the Ctrl key at the same time
to apply the selected option to only the "active" (current) window. Each command found under the "View" menu is
outlined below.
Note that the sensor force data does not change when changing modes, only the appearance of the
display.

Note: Most options within the "View" menu are only accessible if a "Real-Time," "2-D" or "3-D"
Movie window is active. Most view options are grayed out if a "Graph" or "Graph Zoom" window is
active.
2-D displays the image in two-dimensional form, with differences in
occlusal force represented by colors ranging from red (greatest) to
blue (lowest). This display looks the closest to the actual raw output
of the sensor, and individual (square) sensels are seen. When 2-D
display is selected, a dot is visible beside it in the menu, and its
Toolbar icon on the 2-D Movie window is depressed (shown at right).
2-D Contour displays the pressures as a two-dimensional, contoured
image, with differences in occlusal force represented by colors
ranging from red (greatest) to blue (lowest). The sharp corners of
the sensor output are smoothed, making the pressure boundaries
easier to discern. 2-D Contours is the default view. This view most
closely resembles articulating paper marks. When 2-D Contours
display is selected, a dot is visible beside it in the menu, and its
Toolbar icon on the 2-D Movie window is depressed (shown at left).

3-D Columns: Displays a three-dimensional image, in which higher
occlusal contact forces are shown as relative peaks, or columns.
Differences in occlusal force can be distinguished by the colors ranging
from red (greatest) to blue (lowest), as well as by the height of each
column. The relative peaks provide the clinician with visual insight into the
gradients within each color band. When 3-D Columns display is selected,
a dot is visible beside it in the menu.
When a movie is opened, the 3-D Movie window is automatically opened
by default, displaying this "3-D Columns" view. This window can be closed
independently of the other windows. When you are in 3-D Columns mode,
the "Rotate" option becomes available; you may click on the screen with
the mouse cursor to rotate the display 90 degrees clockwise.
Show COF (Trajectory): This menu item is enabled by default. When
enabled, the COF Trajectory icon is displayed in the 2-D Movie window
Toolbar. When disabled, the COF Trajectory icon is not displayed and is
therefore unavailable in the 2-D Movie window. See below for a complete description of the COF Trajectory.
Show COF (Trajectory) enabled in the "View"
menu. This is the default setting. The COF
Trajectory icon can be used to toggle the various
COF Trajectory states (discussed below).
Show COF (Trajectory) disabled in the "View"
menu. The COF Trajectory is "grayed out" and
unaccessible from the Toolbar.
COF Trajectory: This illustrates the "balance" of the occlusion in the active window using a graphic COF "marker" and
"trajectory." The COF marker pinpoints the location of the sum of the total force of the occlusal contacts. The COF
Trajectory displays the history of the path of the Center of Force from the beginning of the recording to the current
frame. The movement of the COF as the patient closes his/her teeth together can be tracked by playing a movie one
frame at a time with COF Trajectory toggled on. The COF Trajectory is represented on the screen by a red and white line
that "trails" the COF marker.
There is also a COF Target, which represents the ideal location of the center of force in a normal subject. This is
displayed on-screen by two "target" circles and a crosshair to denote the center "target."
The COF (Center of Force) and COF Trajectory have three states associated with the icon on the 2-D Movie window
Toolbar:
1. Off: The COF, COF Trajectory and COF Target are all turned off or hidden from view.
2. COF / COF Trajectory on: The COF, COF Trajectory and COF Target are all viewable on-screen.
3. COF on: The COF and COF Target are viewable on-screen.
Note: in a Real-time window, the COF icon only has two states: the first and third outlined above.

The COF marker is the same red and white icon that represents COF on the 2-D Movie window Toolbar. When COF is
enabled, it has a checkmark beside it in the menu, and the 2-D Movie window Toolbar icon is depressed. This option is
not available in 3-D display mode.
In a Real-time window, the COF Trajectory is unavailable. Only the COF marker is displayed. Refer to the Analyzing
Occlusal Force Data section for more detailed information.
IP (Intercuspal Position): When a new movie is recorded, or an existing movie is opened, it is automatically advanced
to the frame in which maximum intercuspation occurs, or the largest area of tooth contact. The IP is a useful reference
for a number of common dental procedures. This option takes into account only those forces that are above the noise
threshold (in the Recording Settings dialog) and the legend’s lower limit. IP is only available when a Movie window is
active, and is unavailable when "MAX" or "Delta" are in effect.
08/01/07
T-Scan III User Manual (Rev L)
53
In the image below, the Movie is opened and automatically advances to the frame in which
maximum intercuspation occurs (IP). In this example, IP occurs at 3.477 seconds into the Movie,
which is displayed on the Status Bar.
To disable this feature, open the Set User Preferences dialog
(under the "Options" menu), and uncheck the "Auto
Intercuspal Position (IP)" checkbox. When unchecked, any
new movie that is recorded, or existing movie that is opened,
does not advance to the IP location. Instead, the window opens
to the first frame.
Max (Maximum Cumulative Force): This allows the user to
view the maximal force of closure for any bite collected over a
series of frames. It does this by displaying a composite movie
frame of the maximum force that each sensel reached over the
selected series of frames. Max allows the dentist to analyze
both static and dynamic data from a recording by providing a
history of the highest tooth contact forces on all teeth, and may
be different from IP, which represents only a single frame of a
recording. Tooth contacts that may have been transient
interceptive contacts show up in Max but may not be present in
IP.
Max can be viewed for the entire movie or from the beginning
of the movie to the IP frame. Max is most useful when viewed over the series of movie frames from the beginning of a
closure to IP, and this is the default ("From 1 -> IP"). To view the Max for the entire movie, open the Set User
Preferences dialog (under the "Options" menu) and under "IP and Max," select "For Whole Movie."
Max is only available when a Movie window is active. When it is enabled, the Movie window Status Bar displays "Max"
(for whole movie) or "Max IP" (for 1 -> IP), and the movie playback options are unavailable. If the COF Trajectory
display is enabled while Max is in effect, the trajectory for the entire range of frames is displayed. The Max option is
"toggled" on and off; when enabled, it has a checkmark beside it in the "View" menu.
08/01/07
T-Scan III User Manual (Rev L)

Delta: The Delta displays an image created by calculating the Max
frame from 1 to IP, then subtracting the IP frame. The Delta feature is
intended to identify the differences between the Max and IP movie
frames, and is used to demonstrate areas representing slides and
potential interceptive contacts otherwise difficult or impossible to
register. Perhaps the most clinically useful application of this option is
identifying differences in occlusal contacts during the guided closure
from centric relation to IP (CR-MIP slide). Many dentists believe this
analysis is key to understanding the health of the occlusion, and Delta
can clearly isolate these contacts for easy identification.
Delta takes into account only those forces that are above the noise
threshold (in the Recording Settings dialog under the Options menu)
and the legend’s lower limit.
Delta is only available when a Movie window is active, and is
unavailable when "Max" or "IP" are in effect. The Delta option is "toggled" on and off; when enabled, it has a
checkmark beside it in the menu, and the Movie Status Bar displays "Max IP minus IP." The movie playback options are
not available when Delta is selected.
The three figures below demonstrate the maximal force of a recorded closure from the beginning of the bite to IP (Max
- shown left), the frame showing IP and the Delta (shown center), or difference in tooth contacts between Max and IP
(shown right).
Arch Model: The Arch Model Superimposes a model of the maxillary arch, as well as an "arch" outline on the tooth
contact data in the active 2-D Movie window. The Arch Model uses a combination of the contact energy outline of the 2D Contour, which defines the arch, and the proportionality of human teeth, to establish the tooth interface
approximations across the arch (source, Ash/Wheeler).
The Arch Outline, which is drawn around the 2-D occlusal force image, provides some additional information for
analyzing your recordings. The Arch Model and Arch Outline are both saved with a movie file.

command found under the "Options" menu is outlined below.
Set Legend: Opens the Legend in the Main Window. The Legend is a segmented force color scale that shows the range
of colors displayed in any open Movie or Real-time windows, and their associated nominal forces. Differences in
occlusal force in these windows can be distinguished by the colors ranging from red (greatest) to blue
(lowest).
The Legend settings can be adjusted by sliding either of two pointers to the right of the scale; this alters the
colors that are displayed in the open windows. If the lower pointer is moved up, all sensed forces below
the level of this pointer are not displayed. If the upper pointer is moved down, the full range of colors are
displayed for the resulting compressed range. The legend, legend marker in the Real-time or Movie
window, and Legend icon on the toolbar all flash to provide a visual indication that the Legend's settings
have been altered.
All open windows are controlled by one legend, and are automatically updated when the pointer is moved.

will use the CR Mode recording time and sensitivity settings; otherwise,
the system will use the IP mode settings. Recording Settings can only be
accessed when a Real-time window is open, and are unavailable from a
2-D or 3-D Movie window.
If you click on the Advanced button, the "Data Acquisition Parameters"
dialog opens, and the user is able to change some of the more advanced
movie recording parameters. From here, the number of Frames to record, and either the Period (elapsed time between
frames) or Frequency (frames per second) can be entered. At the bottom of the dialog box is the "Noise Threshold"
field, which is used to filter out unwanted low level force readings (noise), which is sometimes caused by bending and
crinkling of the sensor.
If you select the "Enable Triggering" option, recording will not start until the patient applies contact force to the sensor.
Once data collection begins, it continues until the specified number of frames are collected. By default, the "Enable
Triggering" option is checked, and triggering is in effect (shown above). Refer to Recording Settings for more

•
Anterior/Posterior Default Position Multiplier: This factor is
used in the 2D Movie window when the "Anterior and
Posterior" icon is pressed, and the window is further
subdivided into four quadrants (left and right, anterior and
posterior). The Central Incisor mm is multiplied by this factor
to calculate the horizontal line default position. The default is 2.15. A higher value moves the division line
closer to the posterior, while a lower value moves the line closer to the anterior.
Note: in order to view the Arch Model Outline, it must also be enabled (checked) under the "View"
menu ("View -> Arch Model").
Sensitivity
The parameters on the "Sensitivity" tab provide automated Sensitivity
checks for each new patient or each new movie that is created.
•
Auto Check Sensitivity: When this option is selected
(checked), the system will check the sensitivity adjustment after
the initial recording in each new patient session. If it
determines that a beneficial adjustment can be made for that
patient’s bite, it will change the sensitivity setting, report how
many levels of adjustment were necessary, and ask whether or
not you would like to redo the movie.
When this option is selected, two other options become
available: "New patient only" and "Every new recording." One of
these options must be selected. These options are outlined

Blank Frames
The "Blank Frames" tab relates to how blank frames are treated
at the beginning and end of the movie. This is useful if there are
several blank frames from the time at which the recording is
triggered to the time data is actually recorded, as well as the
time at which data stops being recorded to the time at which the
recording ends. This helps to trim these frames from the
beginning and end of the Movie.

RECORDING OCCLUSAL DATA
T-Scan III allows you to capture your patient’s occlusal force data over a period of time through a process called
recording. A T-Scan III recording is similar to a video recording, since you can rewind your recording, play it and
replay it as many times as you wish. These force data recordings are also referred to as movies.
Note: Unlike video recordings, T-Scan III movies must be explicitly saved in order to be available
for future review.
TAKING A RECORDING
The T-Scan III system is designed to be easy to operate
and ready to record occlusal data from start up. You may
take a recording using the buttons on the Handle, or
using the buttons in the software Menu and
Toolbar. Both of these methods are described in this
procedure. Follow the steps below to begin recording:
1. Place the sensor support into the Evolution, or
USB Handle; depending on your hardware
configuration.
2. Open the handle latch. Insert the sensor into the
handle, ensuring that the display “This Side UP”
on the sensor is correctly oriented.
3. When you start up the T-Scan III program, the
"Patients" dialog is displayed. Select (highlight)
a patient in the list, then click the Open Patient button, or begin a new patient record by clicking the New
Patient button (shown above right).
4. When the new or existing "Patient Record" is
opened, click the New Movie button to open
a new Real-time window for the patient
(shown at right). Make sure that the Realtime window status bar displays “Sensor
OK.” If it displays "Misaligned!" then reinsert
the sensor into the sensor handle. If it still
displays "Misaligned!" then refer to the
Troubleshooting section.
To open a new Real-time window using the
sensor handle, first make sure that the
correct patient record is active. Press the
New Real-Time Window button on the
scanning handle to activate a new window
(note: to close the real-time window, press
this button once again). To open a new
Real-time window using the menu, select
New Recording from the File menu. You
can alternately select the New Recording
icon on the Toolbar.

Selecting a new recording from the Toolbar.
5. Place the sensor in the patient’s mouth, with the sensor support pointer
between the two central incisors. Keep the scanning handle as parallel to
the occlusal plane as possible.
6. Press the Record Start / Stop button on the handle to begin recording, or
alternately, click the Record icon on the Toolbar in the software. To select
this option using the menu, select Record from the Movie menu. You can
also select this option by pressing the Ctrl+R keyboard combination or F2
key.
Selecting "Record" from the "Movie" menu.
Selecting "Record" from the Real-time window
Toolbar.
Note: The "Record" button is located on the Real-time window, not the Main Toolbar.
7. Wait for your computer to “beep.” This means the system
is ready to record. If your computer does not have
sound, or you do not hear the beep for some reason,
look at the bottom of the Real-time window. The system
is ready to record if the Status Bar displays "Rec. Frame
0 of 800."
8. Have the patient bite down normally on the sensor. The
first tooth contact will cause the system to begin
recording (this is called "Triggering" the recording).
While recording is in progress, the Real-time Status Bar
shows the frame count progress (shown at right).
By default, the first contact on the sensor will trigger the
recording, and 20 frames that lead up to that trigger
event are automatically included at the beginning of the
movie. This assures that if there is any light contact
leading up to the contact that triggers the movie, it will be included in the recording. By using the Triggering
option, the operator needs to be careful not to allow anything to press on the sensor before the intended event
occurs, as this may cause premature recording. The operator should also coach the patient not to bite the
sensor too soon to avoid premature recording. Refer to the Recording Settings section for further information.

9. When the correct number of frames has been collected, recording automatically stops. If you want to manually
stop recording before this time, press the Record Start / Stop button on the scanning handle. You may also
manually stop recording by selecting Stop from the Movie menu, clicking the Stop icon on the Toolbar, or
pressing the F4 key on the keyboard.
Selecting "Stop" from the "Movie" menu.
Selecting "Stop" from the Main Toolbar.
10. As soon as a recording is complete, the Real-time window becomes a Movie window. You may now review and
analyze the recorded occlusal force data (refer to the Reviewing a Movie and Analyzing Occlusal Force Data
sections). If the first recording is not successful for any reason, you can easily create another recording
following the above steps.
Once recording is complete,
a number of functions are
automatically performed. The
system sensitivity is checked
(and adjusted if necessary),
any blank frames are
removed from the movie,
Graph and Graph Zoom
windows are displayed, the
Movie and Graph windows
are tiled (vertically), an
"Arch Model" is displayed,
the "COF Trajectory" is
displayed, and the new movie
is automatically forwarded to
the maximum Intercuspal
Position (IP) frame. These
functions (except for the
"COF Trajectory") can be
adjusted or disabled in the
Set User Preferences dialog.
12. If the system finds the default sensitivity setting does not
match your recording, it will adjust the sensitivity setting,
and provide a prompt on-screen asking whether or not you
would like to re-record the movie with this updated setting.
Click the Keep the recording and review the data button if
you would like to override this setting and keep the
recorded movie "as is."
Note that clicking the "Keep the recording and review the
data" button may provide you with inaccurate readings.
Most of the time you will want to redo the movie with the sensitivity changed to get better results.
Refer to the Automatic Sensitivity Adjustment section for further information.

13. The newly recorded movie is automatically named, using the active patient’s first, last and middle names. Refer
to the Autonaming section for further details. To save this movie as a file, using this "automatic" name, select
Save Movie from the File menu. The "Add Movie to Database" dialog is displayed, and you may choose whether
or not you would like the movie to be part of the database, change any associated "Comments" (Change
Comments button) and associate a "Diagnosis / Procedure" to the movie. Refer to the Using the Patient File
Management System section for more information.
If this is the first saved recording for this patient, a folder is created inside the "Database/Movies" folder on
your hard drive using the patient’s last, first, and middle names. For example, a patient named John R. Smith
would have the following folder titled "Smithjohnr" created on the hard drive. By default, this patient’s saved
movies are placed in this folder.
If you wish to save the movie as a different file name or in
a different location / path on the hard drvie, select Save
Movie As from the File menu. T-Scan III movie files are
saved with the extension *.fsx.
AUTONAMING
T-Scan III makes it easy to keep track of a patient’s occlusal recordings by automatically naming saved movies. Once
they are recorded, patient movie files are named using the first four letters of the patient’s last name, the first letter of
the patient’s first name, and a two-digit number. For example, assume the patient’s last name is Smith and first name is
John, and this is the first movie you are recording for this patient. The movie will be named smitj01, where:
smit
j
01
08/01/07
are the first four characters of the patient’s last name
is the first character of the patient’s first name
is the number assigned sequentially by the system to each movie (i.e., the second movie for John Smith
will be number 02)
T-Scan III User Manual (Rev L)
80
When you record your first patient movie, a folder named "Database" is created in the same directory as the T-Scan III
program, and a folder named "Movies" is placed inside the "Database" folder. A folder is then created for the patient
inside the "Movies" folder, using the patient’s last, first, and middle names. For example, for a patient named John R.
Smith, the folder would be titled "Smithjohnr." By default, this patient’s saved movies are placed in this folder.
AUTOMATIC SENSITIVITY ADJUSTMENT
The T-Scan III software has an automatic sensitivity adjustment, which aligns the sensor’s output with the biting force
of the patient. The system does this by measuring the contact force for the bite and distributing this force over a
predetermined range, represented by the color range of red (highest force) to blue (lowest force). This adjustment
ensures a reliable range of bite force, which highlights the relative differences of the significant contacts without
overloading the sensor.
The system does not check the sensitivity setting by default.
However, you can specify whether or not to enable Automatic
Sensitivity Adjustment after the initial recording in each new
patient session or after each new recording. To do this, go to the
Set User Preferences dialog (under the "Options" menu).
The following outlines the options available within the
"Sensitivity" tab on the "Set User Preferences" dialog.
•
Auto Check Sensitivity: When this option is selected
(checked), the system will check the sensitivity
adjustment after the initial recording in each new
patient session.
When this option is selected, two other options become
available: "New patient only" and "Every new
recording." One of these options must be selected.
These options are outlined below.
•
New Patient Only: Selecting this option automatically checks the sensitivity each time a new patient is created.
The system will make an adjustment only once for each new patient (after recording the first movie for each
new patient). Following this single adjustment, the
clinician should be aware of recording results and
make manual changes using the "Manual Sensitivity
Adjustment" feature, located in the middle of the
Arch at the bottom of the Movie window (shown at
right). Manually setting the Sensitivity can only be
done prior to taking a new recording.
•
Every New Recording: Selecting this option
automatically checks the sensitivity each time a new recording is created.
08/01/07
T-Scan III User Manual (Rev L)
81
If the Automatic Sensitivity Adjustment determines that a beneficial
adjustment can be made for that patient’s bite, it will change the
sensitivity setting, report how many levels of adjustment were
necessary, and ask whether or not you would like to redo the movie
(shown at right).
Note that clicking the "Keep the recording and review the
data" button may provide you with inaccurate readings.
Most of the time you will want to redo the movie with the
sensitivity changed to get better results. Refer to the
Automatic Sensitivity Adjustment section for further
information.
The system will make a single adjustment; after this, the sensitivity is no longer checked by the system and any
adjustments are left to the clinician. The clinician should be aware of subsequent movie results and make manual
changes, if necessary. Refer to the Manual Sensitivity Adjustment section for instructions.
Keeping this feature enabled is recommended, because without Automatic Sensitivity, the data may not be a true
assessment of the relative force of the occlusal contact data if you make an incorrect manual adjustment.
REVIEWING A RECORDING
Once you have made a recording (movie), it is available for your review. Your movie consists of a certain number of
frames of occlusal force data that is "captured" during the recording period. This section reviews the basics of movie
playback.
The playback options control all open movie windows (and corresponding graphs) in unison, regardless of which
movie is active. Press Ctrl on your keyboard if you have more than one movie open, and you want the selected playback
option to affect only the active window. If a movie window is "Paused," it will not respond to the playback commands.
Playing back the recording
1. Either record a current Real-time window, or open a T-Scan
III movie file (with the extension *.fsx).
2. Use the Movie menu commands and corresponding Toolbar
icons to review the movie, as follows:
Note: Many of the options found under the "Movie" menu
or on the "Toolbar" have equivalent Keyboard Shortcuts
that can be used to review the movie. Often times, these
keyboard shortcuts are faster than using their Toolbar or
Menu equivalents.

INCLUDING COMMENTS WITH A RECORDING
The Comments option allows you to view, add, and edit the contents of the comment fields associated with the currently
active Movie or Real-time window. The comment fields can be filled in before a recording is taken (i.e. in a Real-time
window), between recording and saving, or after saving.
These comment fields can be useful for recording information about a particular session, such as the doctor or
clinician’s name, or treatment method. The "Comments" dialog (shown above) displays the information from the Patient
Record (i.e. Name, Patient ID, Gender, Date of Birth, etc.), and allows you to create additional comment fields and add
free-form comments. In this way, Comments can serve as a Medical History, and an Evaluation and Treatment Record
for each patient.

LINKING A PHOTO TO A MOVIE FRAME
The Link Photo feature allows you to open a photo file and link it to any frame of a Tekscan (*.fsx) movie. Since the
photo is linked to a frame of the movie, it becomes possible to associate one or several photos to a single movie. The
amount of photos is dependant only on the length of the movie. Conversely, you can only associate one photo per frame.
You cannot have multiple photos linked to a single frame. The following image file formats are supported:
*.bmp;*.jpg;*.gif;*.tif;*.pcx;*.tga.
Note: The “Photo Link” option is only available if a movie is open within the Tekscan software. If
there is no open movie, the “Link Photo” option is grayed out and unavailable.
The following highlights some benefits from using this feature:
•
Procedure documentation is enhanced for all or any part of a movie. You can link several photos to a single
movie, thereby documenting each step of a given procedure.
•
Create a visual catalog for your movies. Once a photo is associated to a frame of the movie, you can instantly
recognize when the movie was recorded by viewing the linked photo. In addition, you can include comments to
the movie to explain why the photo is linked to the movie.
Associating a Photo to a Movie Frame
Follow the steps below to associate a photo to a frame of the movie:
1. Open the movie for which you would like the photo
associated (shown at right).
2. Advance the movie to the time index for which you would like
the photo associated (shown below left). You must select a
time index for your movie. If you do not, the photo is
automatically associated with the beginning of the movie at
time index "0."
3. Go to File -> Link Photo (shown below right).

Toolbar and Status Bar Options
When a photo is linked to the frame of a movie,
the following toolbar and status bar options are
available from the top and bottom of the photo
window, respectively:
•
Select Photo: This option lists all
photos that are linked to the current
movie. Clicking on the drop-down
arrow allows you to select from any of
these linked photos. When a photo is
selected, the movie automatically jumps
to the corresponding linked frame.
•
Add Photo: Allows you to add a photo
and link it to a movie frame.
•
Remove Current Photo: Allows you to
remove the currently displayed photo,
thereby removing its link to the movie’s
frame.
•
Copy Photo: This command copies the photo to the windows clipboard. You can then paste the photo to any
other application that supports photo files, such as Microsoft Word or Excel.
•
Select Size (Zoom): Allows you to quickly select from a number of preset zoom factors. Options are 25%,
33%, 50%, 75%, 100% and Fit to Window. These scale factors are relative to the original photo size. You can
also drag from the bottom-right edge of the window to expand or contract the photo and photo window, while
maintaining the photo’s aspect ratio. Note: the photo’s current scale is also displayed as a percentage within the
middle of the status bar.
Movie Playback
During movie playback, when one photo is linked to a movie, the photo is continually displayed for the entire duration
of the movie.
If more than one photo is linked to the movie, when the movie is played, the photo switches to the next photo at the
frame for which the photo is linked. For example, if you associate Image1 to frame 1 and Image2 to frame 193, when
the movie plays from the beginning, Image1 is displayed until the movie reaches frame 193. When the movie reaches
frame 193, Image2 is displayed until it reaches another frame for which a photo is associated, or until the end of the
movie if no other photos are linked to the movie.
Smart Docking
By default, the photo is docked to the right side of the movie window (called “Smart Docking”). When you drag the
movie around the screen (by clicking on the Title Bar of the movie and dragging with your mouse), the photo window
moves with the movie. This helps you identify photo windows in situations where you have several movie and photo
windows open on-screen at once.
08/01/07
T-Scan III User Manual (Rev L)
88
Conversely, you can move the photo window independently of
the movie window by clicking and dragging on the photo
window’s Title Bar. The reason for this is so that you can dock
the photo window to a different side of the movie window. If,
for example, you want the photo to dock to the left side of the
movie window instead of the right, you can click and drag the
photo window’s title bar and move the photo window to the
right side of the movie window. When you then move the movie
window around the screen, the photo window automatically
docks to the left side of the movie window.
If you prefer to unhinge the photo window entirely so that the
movie window moves independently from the photo window,
right click and select Disable smart docking from the context
menu (see image at right). You can now move both windows
independently of one another.
Copying Linked Photos
Using the Copy Photo command located as an icon on the
toolbar, you can copy any photo to the windows clipboard. The
copy can then be pasted to any other application that supports
photo files, such as Microsoft Word, PowerPoint or Excel.
When you copy and paste the photo in this manner, the photo
is always displayed at its original photo size. If you want to
keep the photo’s size the same as what you see on-screen,
right-click over the photo window. From the context menu,
select Copy Photo (Current View Size). When the photo is
pasted into other programs, the size will remain consistent
with the photo’s current view displayed within the Tekscan
software.
Missing Photo Links
When a photo is linked to a frame of the movie, there is a connection that is
made between the photo file location and the movie. If the photo is moved, this
connection is broken. When this happens, your photo is no longer displayed
when the movie is opened (see image at right).
To correct this situation, first remove the file using the Remove Current Photo
icon on the toolbar, and then link the photo once again by clicking the Add
Photo icon on the toolbar. When the “Open” dialog is displayed, select the
new location for the photo; where the photo was moved. The photo is visible
once again.

Printing the Movie Frame and Photo
To print the photo without the movie, first select the photo window by clicking the photo window’s Title Bar. It will turn
blue. Then go to File -> Print. The Photo prints out along with the Tekscan software version, Frame number to which
the photo is associated, and full path to the file’s location on your hard drive (see image below).
If you would like to print both the movie and photo window at the same time, first select the movie window by clicking
the movie window’s Title Bar. It will turn blue. Then go to File -> Print Setup. Ensure the “Photo” checkbox has a
checkmark located in it (see image below). This is checked by default.
Click OK to close this dialog box. Then go to File -> Print. Both the movie frame and photo are printed at the same
time.

ADVANCED RECORDING OPTIONS
This section describes some of the more advanced options when taking a recording with the T-Scan III system, such as
Recording Settings and Manual Sensitivity Adjustment.
Recording Settings
The T-Scan III system is factory set with default settings that will provide
an excellent recording of your patient’s occlusion; however, you have the
ability to adjust these parameter values. Follow the instructions below to
change these default parameters.
3. Select Recording Settings from the Options menu. The
"Recording Settings" dialog is displayed. Here you can adjust the
IP (Intercuspal Position) mode and CR (Centric Relation) mode
recording settings, and access the more advanced recording
options.
When the system is in CR Mode, it uses the "CR recording time"
and "CR Sensitivity" settings; otherwise, it will use the "IP
recording time" and "IP Sensitivity" settings.
Note: The "BioPAK recording time" option is only available
with the BioResearch Integration Module.
2. To change the total length of time that the system records occlusal data, enter a value (in seconds) in either the
"IP recording time" or "CR recording time" field. You may enter any value into these fields as long as it falls
into the allowable range displayed above the field (in brackets). The default recording time for IP mode is 10
seconds, and for CR Mode is 12 seconds.
3. To adjust the system’s sensitivity setting, click on either the "IP Sensitivity" or "CR Sensitivity" button. An "Adjust
Sensitivity" dialog opens, and you can manually adjust the sensitivity for that mode. The default sensitivity for
"IP mode" is "Default" and "CR mode" is "Mid-2." Refer to the Manual Sensitivity Adjustment section for more
information.
Default "IP mode" setting: Default.
08/01/07
Default "CR mode" setting: Mid-2.
T-Scan III User Manual (Rev L)
91
4. Click the Advanced button for additional options. The "Data Acquisition Parameters" dialog opens, and you are
able to change the following recording parameters:
Note:Allowable ranges for recording parameters are shown in parentheses.
•
Frames to Record: The total number of frames to be recorded. The default number of "Frames to
record" is 1000.
•
Period: The amount of time between frames. The default is 0.01 seconds
•
Frequency: The number of frames that are recorded each second. The default is 100 frames per
second.
•
Duration: The Duration, which is the same as the "Recording time," is calculated based on the other
parameters and displayed in the dialog box. The default is a recording time of 10 seconds.
5. Wrinkling of the sensor may sometimes produce force readings ("noise") to appear in your Real-time window
when no force is applied to the sensor. You can eliminate such noise from your data by entering a higher value
in the "Noise Threshold" field. The software sets forces equal to or less than this "Noise Threshold" to a value of
zero. The default "Noise Threshold" value is "18."
Note: An alternate way to mask noise is to raise the minimum
value (lower arrow) in the Legend. This does not eliminate the
noise from the recording however, it only keeps it from being
displayed.
6. With the "Triggering" feature enabled, once the dentist or clinician initiates a recording, the T-Scan III system
waits to begin recording occlusal force data. When it senses the first contact on the sensor, the recording
begins. Once recording begins, it continues until the specified number of frames ("Frames to record") are
collected.
By default, the "Enable Triggering" option is checked, and triggering is in effect. If you wish to disable this
feature, click (to de-select) the "Enable Triggering" checkbox.
08/01/07
T-Scan III User Manual (Rev L)
92
It should be noted that 20 frames are added to the beginning of the recording if the recording is triggered and
there is a wait time between pressing the “Record” button and the first contact. This is termed "pre-triggering,"
and is visible within the graph once the recording has been taken. If there is contact on the sensor while the
“Record” button is pressed, these 20 frames are not added to the movie and the recording starts on the first
frame.
Pre-triggering assures that if there is any light contact leading up to the contact that triggers the movie, it will be
included in the recording. By using the Triggering option, the operator needs to be careful not to allow
anything to press on the sensor before the intended event occurs, as this may cause premature recording. Also
coach the patient not to bite the sensor too soon to avoid premature recording.
The majority of the time you can visually see whether or not a
movie has been triggered by looking at the graph after the
recording has been taken. If the 20 frames are there, you know
that the recording was triggered.
The following displays the 20 frames of blank data that are
added to the beginning of the Movie. The red trace denotes the
start of forces acting on the sensor.
7. When you are satisfied with the values in the "Data Acquisition Parameters" dialog, click OK. These settings
remain in effect until you change them (even if you close the T-Scan III program), or until the "Default"
button is clicked. Click the Default button to set all the parameters to their original values.
CR (Centric Relation) Mode
When CR Recording Mode is selected from the 2-D Movie window Toolbar, the current
Real-time window switches to CR (Centric Relation) Mode.
When this mode is in effect, the Real-time window uses the CR Mode recording settings ("CR recording time" and "CR
Sensitivity") to record occlusal data; otherwise, it uses the standard IP mode settings ("IP recording time" and "IP
Sensitivity"). Refer to the Recording Settings section for information on how to change any of these settings.
The importance of isolating the Centric Relation Prematurity when performing an Occlusal Equilibration has been
advocated by numerous authors . It is believed that when the mandible is properly positioned in Centric Relation, both
articular discs are properly positioned between the head of the mandibular condyle and the superior aspect of the
eminentia, such that there is no stimulus for antagonistic muscle hyperactivity .
1-4
5
Generally, the Centric Relation Prematurity can be located by various methods involving operator-guided mandibular
positioning. The method advocated by Dawson, known as Bimanual Manipulation , has been widely recognized and
accepted as a predictable way to guide the mandible into the Centric Relation position. The first occlusal contact that
results from the Bimanual Manipulation procedure is known as the “Centric Relation Prematurity”.
6-8
8
Historically, to locate the Centric Relation Prematurity (first tooth contact), the operator relied on the patient to
describe the general location of the first tooth-to-tooth contact that they “felt” as the guided jaw manipulation brought
the first few teeth into contact. With the T-Scan III system, you can locate the Centric Relation Prematurity simply by
viewing the first contact that increases in force, as displayed on your computer monitor.
The CR Mode settings were designed to be more appropriate for procedures involving the Centric Relation Prematurity
and guided closure analysis. The default “recording time” and “frames to record” for CR Mode is 12 seconds and 1200
frames, respectively. The default ‘sensitivity’ setting is higher for CR Mode than for IP mode ("Mid-2" versus "Default"),
because the dentist is creating the force of closure by pressing on the mandible and the muscles of mastication are
disengaged, so this higher sensitivity setting may be necessary to identify the early contacts in guided closure.

Turbo Mode
Turbo Mode allows you to maximize the number of frames that can be captured per second. This can be beneficial for
high-speed applications, when trying to achieve the maximum frame rate. The frame rate depends on the amount of
load on the sensor. Typical occlusion will be about 300 Hz (300 frames per second). Turbo mode captures data at
approximately 500 Hz (500 frames per second). With turbo mode enabled, rapid, transitory events can be captured at
the sacrifice of consistent frame rate. Recordings captured using turbo mode will have many more frames than movies
made at slower speeds.
Note: The Turbo Mode option is only available with the Evolution System. It is not available with
the USB system.
To enable "Turbo Mode", do the following:
1. Go into Options -> Recording Settings (shown at right).
2. When the "Recording settings" dialog opens, click the Advanced button
(shown at right).
3. When the "Data Acquisition Parameters" dialog opens, place a checkmark in the Turbo Mode checkbox
(shown below).
When a checkmark is placed in the "Turbo Mode" checkbox, the
"Period" and "Frequency" parameters are unavailable. This means
that the hardware is operating at its maximum capacity; capturing as
many frames as possible. The maximum frequency is approximately
500 frames/second.

Manual Sensitivity Adjustment
Although the T-Scan III system provides an automatic sensitivity adjustment, certain clinical procedures may require
manual adjustment of this setting. For example, guided closure analysis is aided by selecting a higher than normal
sensitivity setting, because the dentist is creating the force of closure by pressing on the mandible and the muscles of
mastication are disengaged. In this example, the highest sensitivity setting may be necessary to identify the early contacts
in guided closure.
The sensitivity adjustment feature allows you to manually adjust the sensitivity settings for your system, when necessary.
The manual adjustment is not recommended, however; and the Auto Check Sensitivity (Set User Preferences) feature
should be enabled whenever possible.
The T-Scan III system offers two recording modes with different sensitivities.
•
IP (Intercuspal Position): This is the default recording mode. The IP sensitivity level is set to the same level
that is used in the current patient’s last treatment session. For new patients, it is set to the "Default" level. After
the first recording for each new session, the software performs the automatic sensitivity adjustment (if
enabled). IP Sensitivity is designed to remember different sensitivity levels for each patient to match the varying
levels of bite force at full closure.
•
CR (Centric Relation): CR sensitivity is used when the CR button is pushed. By default, it is set to Mid-2. The
CR sensitivity level is the same with all patients and does not change with the automatic sensitivity adjustment.
For more information, refer to CR (Centric Relation) Mode.
08/01/07
T-Scan III User Manual (Rev L)
95
Advanced users may also find that it is more clinically efficient to select a mid-range setting for routine use, but care
must be taken not to overly distort the optimal range of the data distribution. Collecting data with the auto-adjust
sensitivity feature disabled results in the higher range forces being masked because the sensor is prevented from
differentiating them due to lack of range.
Manually adjusting the sensitivity
There are two ways to manually adjust the sensitivity, as follows:
1. Sensitivity adjustment buttons are located at the bottom of the Real-time
window. Clicking the blue downward arrow on the left decreases sensitivity.
Clicking the red upward arrow on the right increases sensitivity. The current
level of sensitivity is displayed in the center.
Note: Manual sensitivity adjustment is only available from a Real-time
window.
2. With a Real-time window open, select Recording Settings
from the Options menu. The "Recording Settings" dialog
opens. Here you can adjust the sensitivity settings for both
the "IP mode" and "CR mode."
There are 8 possible sensitivity settings, ranging from "Low-1
(Min)" to "High-2 (Max)." Click on the desired sensitivity
setting radio button to select it, or click the T-Scan III
Default (Default) button to bring the sensitivity back to the
default level.
Adjust the sensitivity while your patient bites on the sensor,
so you can see the results immediately, and can ensure that a
good color range is achieved for the applied forces. When
you are satisfied with your choice, click the OK button to exit
the dialog and have your changes take effect.
Note: You can view the sensitivity setting at any time by selecting "Settings" from the "Options"
menu, and clicking the "Sensitivity" tab.

USING THE PATIENT FILE MANAGEMENT SYSTEM
The T-Scan III software comes with a full-featured patient file management system. This system can be used to store
each patient’s information (first and last name, patient ID, etc.), as well as store and track each movie associated with
that patient. This system is a powerful tool for managing client records. It will help to cut down on paperwork and make
keeping track of your patient’s movie files simple.
PATIENTS & THE PATIENT LIST
The "Patients List" feature enables you to manage your
patient files. The "Patients" dialog is opened
automatically when you start the T-Scan III software.
From here, you can view a list of the patients in the
management system, enter a new patient or remove an
existing patient from the system, or open an existing
patient record. It also provides a patient search option
and the ability to identify patients that have had certain
procedures performed.
Accessing the Patient List
Select Patients from the File menu, or click the
Patients icon in the Main Toolbar. The "Patients"
dialog is opened.
Note that this dialog box is opened automatically when you start the software.

Patients are listed on the left side of the "Patients" dialog. When you select (highlight) a patient in this list, the patient’s
name and ID number are displayed in the field above the list, and the patient’s pertinent information is displayed to the
right. This information consists of the patient’s first, last and middle names, patient ID, date of birth, gender, date and
time the patient was entered into the system, and a list of all of the patient’s movies (T-Scan III recordings).
Searching the System for a Patient
The following procedure should be used to search the
Patient File Management System for a patient.
1. Open the "Patient List," as described in the
Accessing the Patient List section.
2. In the top right corner of the "Patients" dialog,
type the patient’s last name into the "Search by
last name" field. The first patient with the
entered last name is highlighted in the list.
Patient Records
A Patient Record can contain the following
information: patient’s first, last, and middle names,
patient ID, gender, date of birth, a list of available
movies (T-Scan III recordings), and each of these
movies’ information. The patient record also includes an option, called "Identify Movies by Procedure", which allows
you to distinguish movies based on the procedure
used in that patient session. In addition, the
Movie Diagnosis/Procedure is displayed for each
movie, and can also be changed by clicking the
Change button on the right.
The movies are listed (on the left side of the
patient record) by the date and time they were
recorded. When a movie in this list is selected
(highlighted), all of the information pertaining to
that movie is displayed to the right. The movie
information consists of the date and time that the
movie was created, any comments that were
saved with the movie, the movie file name, and
the path (location) at which the movie files is
stored.

from the database. The movies are still available on your
hard drive and can be associated to other patients, if desired.
•
Confirm file deletion one by one: This option will go through each file one by one and ask you if you
want to delete each file. For each file that is associated with the patient, you will see the following
message:
Delete all files from hard disk: This option will delete both the patient and all movie files associated with
the patient. It is the all-inclusive way to delete all traces of the patient, and therefore should be used with
caution. Once this option is used, you cannot retrieve the patient, or their associated movie files. They are
permanently deleted.
PATIENT MOVIES
This section contains information on how to work with your patients' movies within your T-Scan III Patient File
Management System.
Adding a New Movie to the System
The following procedure outlines how to add a new movie to the Patient File Management System.
1. When you initially open the software, a Real-time window opens (assuming the Handle is properly connected).
Record a movie. Refer to the Recording Occlusal Data section for details and instructions.
2. Once the movie is recorded, it is not yet associated with
any patient. You must decide whether or not you want the
movie associated with a patient. To associate a movie to a
patient, and save the movie under that patient's movie list,
go to File -> Save Movie.
08/01/07
T-Scan III User Manual (Rev L)
103
The following dialog opens (shown at right).
Click on the patient's name. This is the patient you
want associated to the movie. The patient's name is
displayed under the "Selected Patient" field as
shown below.
Click the OK button. The movie is now saved and associated to your patient. Once you associate a patient to a
movie, any subsequent Real-time windows you open or movies you take are also associated with this same
patient.
3. Patient movie files are automatically named, using the first four letters of the patient’s last name, the first letter
of the patient’s first name and a two-digit number. For example, with a recording of a patient named John B.
Smith, the first recording would be titled ‘SmitJ01’. Refer to the Autonaming section for more detailed
information.
4. If you simply close the recording, before saving it as a file, you will be
asked whether or not you want to save changes to the movie. Click Yes
to display the "Add Movie to Database" dialog box.
5. When you record your first patient movie, a folder named "Movies" is created in the same directory as the TScan III program. A folder is then created for the client inside "Movies", using the patient’s last, first, and
middle names. For example, with a patient named John B. Smith, the folder would be titled ‘Smithjohnb’. By
default, all of this patient’s saved movies will be placed in this
folder.
6. If you want to change the comments associated with the movie,
before it is saved, click the Change Comments button in the
"Add Movie to Database" dialog box. The Comments dialog is
displayed, and you can make changes or additions to the
comment fields.
Creating a New Movie associated to a Different Patient
The following procedure should be used to switch to a different patient within the Patient File Management System and
associate new movies to that patient.

3. Once this new patient is open, any subsequent
Real-time windows you open or movies you take
are also associated with this same patient.
Recording a series of movies
If you decide you would like to record a series of movies,
you can continuously open new Real-time windows and
create several recordings in a row without saving.
Provided the movies are all going to be associated with the
same patient, you can select one of the unsaved movies,
and go to File -> Save Movie. Once within the "Save

Marking a Movie by Diagnosis or Procedure
When saving a movie to the Patient File Management System, you have the option of "marking" it by the diagnosis or
procedure that was performed. This information is saved with the recording, and can be used to "sort" movies later.
1. Record a movie, then select Save Movie from the "File" pull-down menu. The "Add Movie to Database" dialog
is displayed. This dialog shows the movie’s information, such as the date and time it was created, the file name
(automatically generated) and path, as well as the patient’s information.
2. At the bottom of the "Add Movie to Database" dialog is the Diagnosis/Procedure field. By default, this field is
set to "None," and you can enter any Diagnosis/Procedure
that applies to your application. Keep in mind when
entering information into this field that it remains within
your database as a future option from which you can
select; available for selection on all future patient movies.
For this reason, you may want to draft a short list of
diagnosis/procedures from which to select, and enter
them into this field until you have a standard list. Otherwise, you can end up with a very lengthy list of options.
3. Select the desired diagnosis/procedure, or type in the name of a diagnosis/procedure you wish to add to this
list, to "mark" the movie. Later, in the Patient List or a Patient Record, an asterisk (*) is placed next to this
movie’s title and/or the patient’s name when you select this procedure in the "Identify Movies by
Diagnosis/Procedure" field. Refer to the Identifying a Patient by Diagnosis/Procedure section for further
information.

AUTOMATIC PATIENT SYSTEM BACKUP FILES
Each time you close the program, a new backup file is created automatically. If you have made any changes to your
system, these changes are saved. This helps to protect the data stored within your system.
The first time the backup is created, the file -- "tekscan1.mdb" -- is saved in your C:/windows/system directory. If you
backup the system a second time, an additional file -- "tekscan2.mdb" -- is saved. Any further backups will cause the
earliest backup file to be replaced (overwritten).
Note: The standard system backup directory is "C:\windows\system." The name of this directory
may vary slightly, depending on your installation of MS Windows.

ANALYZING OCCLUSAL FORCE DATA
As you review Real-time or recorded occlusal force data, you will want to make use of the many diagnostic analysis tools
that T-Scan III provides. The main analysis options are: Display, Lines, and Graphs. Each of these features provides you
with a number of ways to present the data, which enables you to focus on specific aspects of the dynamic force
relationships of the contacts. The following sections describe how to best utilize these analysis options.
DISPLAY OPTIONS
The following T-Scan III display options are essential in the analysis of occlusal data. 2-D and 3-D Views, COF / COF
Trajectory, IP (Intercuspal Position), Max (Maximum Cumulative Force), Delta, and Arch Model. These analyses
are designed to enable the clinician to summarize the occlusal contacts in useful formats, with the force and time
relationships of the contacts displayed as color images.
Note that "IP," "Max," "Delta" and "Arch Model" are not available in Real-time mode .
These features, such as IP and Max, assist the dentist in the diagnosis and treatment planning of occlusal disease, such
as trauma caused by transient forces and interceptive contacts. T-Scan III also provides subtractive technology (Delta)
to isolate slides and other pathology from the occlusion, providing previously unavailable information. Center of Force
analysis allows the dentist to examine the total effect of restorative dentistry on the patient’s maximum closure and
excursions, and is as easy as the click of a mouse.
Note: When any of these View options is selected, it affects all open windows. Press the Ctrl key at
the same time to apply the selected option to only the ‘active’ window.
2-D / 3-D Views
2-D displays the image in two-dimensional form, with differences in
occlusal force represented by colors ranging from red (greatest) to
blue (lowest). This display looks the closest to the actual raw output
of the sensor, and individual (square) sensels are seen. When 2-D
display is selected, a dot is visible beside it in the menu, and its
Toolbar icon on the 2-D Movie window is depressed (shown at
right).
2-D Contour
displays the
pressures as a
two-dimensional,
contoured image,
with differences in
occlusal force
represented by
colors ranging from red (greatest) to blue (lowest). The sharp
corners of the sensor output are smoothed, making the pressure
boundaries easier to discern. 2-D Contours is the default view. This
view most closely resembles articulating paper marks. When 2-D
Contours display is selected, a dot is visible beside it in the menu,
and its Toolbar icon on the 2-D Movie window is depressed (shown
at left).
08/01/07
T-Scan III User Manual (Rev L)
115
3-D Columns: Displays a three-dimensional image, in which higher
occlusal contact forces are shown as relative peaks, or columns.
Differences in occlusal force can be distinguished by the colors ranging
from red (greatest) to blue (lowest), as well as by the height of each
column. The relative peaks provide the clinician with visual insight into the
gradients within each color band. When 3-D Columns display is selected,
a dot is visible beside it in the menu.
When a movie is opened, the 3-D Movie window is automatically opened
by default, displaying this "3-D Columns" view. This window can be closed
independently of the other windows. When you are in 3-D Columns
mode, the "Rotate" option becomes available; you may click on the screen
with the mouse cursor to rotate the display 90 degrees clockwise.
COF & COF Trajectory
The COF and COF Trajectory illustrates the "balance" of the occlusion in
the active window using a graphic COF "marker" and "trajectory." The COF marker pinpoints the location of the sum of
the total force of the occlusal contacts. This is done by calculating the sum of the medio-lateral and antero-posterior
force moments of the recorded contacts, and presenting this data by superimposing the COF marker on the tooth
contact data.
The COF Trajectory displays the history of the path of the Center of Force from the beginning of the recording to the
current frame, in relation to the COF target. The movement of the COF as the patient closes his/her teeth together can be
tracked by playing a movie one frame at a time with "COF Trajectory" toggled on. The trajectory is represented onscreen by a red a white line that "trails" the COF marker.
This powerful analysis tool can be used to determine the influence of interceptive contacts, estimate the stability of a
closure, and track the trajectory of an excursive movement.
Viewing COF and COF Trajectory on-screen
The COF (Center of Force) and COF Trajectory have three states associated with the icon on the 2-D Movie window
Toolbar:
1. Off: The COF, COF Trajectory and COF Target are all turned off or hidden from view.
2. COF / COF Trajectory on: The COF, COF Trajectory and COF Target are all viewable on-screen.
3. COF on: The COF and COF Target are viewable on-screen.
Note: in a Real-time window, the COF icon only has two states: the first and third outlined above.
08/01/07
T-Scan III User Manual (Rev L)
116
Position number 1: Off.
Position #2: COF / COF Trajectory on.
Position #3: COF on.
The COF marker is the same red and white icon that represents COF on the 2-D Movie window Toolbar. When COF is
enabled, it has a checkmark beside it in the menu, and the 2-D Movie window Toolbar icon is depressed. This option is
not available in 3-D display mode.
In a Real-time window, the COF Trajectory is unavailable. Only the COF marker is displayed. Refer to the Analyzing
Occlusal Force Data section for more detailed information.
COF Target
The COF marker is shown in relation to a dual elliptical target, which represents the ideal location of the center of force
for any maximum intercuspation closure, and acts as a guide with respect to a normal occlusion. The inner ellipse
shows the area within which the COF of 68% of a normal population is found, and the outer ellipse shows the area
within which the COF of 95% of a normal population is found.
08/01/07
T-Scan III User Manual (Rev L)
117
The COF target is displayed on-screen by two "target" circles and a crosshair to denote the center "target."
The relationship between the Center of Force marker and target is not intended to be an absolute measure of normal
occlusion, but to serve as a guide for the dentist to compare the patient’s occlusion to that of a group of normal
subjects.
The rationale for the center of force target came from the work of Maness et al, who described the mean location of the
distribution of occlusal contacts in maximum intercuspation; and from Mizui, et al, who quantified occlusal force in the
intercuspal position (see Appendix A. Background for COF Analysis).
Positioning the COF Target
The user has the ability to adjust the position of the COF target in Set
User Preferences (under the Options menu) if it is necessary. These
options are outlined below.
Note that the Center of Force (COF) must be enabled
using the COF icon on the Movie window Toolbar for any
of these parameters to be relevant.
•
Threshold: (O-100): Only those force values that are
above the COF Trajectory "Threshold" value (relative to the
maximum force within the movie) are displayed when COF
Trajectory is selected (under the "View" menu). In this
way, the user has some control over which frames of the
movie are used to calculate the COF Trajectory.
•
From Sensor Top: The COF "Target Position" enables you
to adjust the location of the automatically generated COF
Target. You can type in a value for the distance "From Sensor Top," in millimeters, to position the COF Target.
•
From Sensor Left: The COF "Target Position" enables you to adjust the location of the automatically generated
COF Target. You can type in a value for the distance "From Sensor Left," in millimeters, to position the COF
Target.
Showing/Hiding the COF (Trajectory)
The Show COF (Trajectory) "View" menu item is enabled by default. When enabled, the COF Trajectory icon is
displayed in the 2-D Movie window Toolbar. When disabled, the COF Trajectory icon is not displayed and is therefore
unavailable in the 2-D Movie window.
Show COF (Trajectory) enabled in the "View"
menu. This is the default setting. The COF
Trajectory icon can be used to toggle the various
COF Trajectory states (discussed below).
08/01/07
Show COF (Trajectory) disabled in the "View"
menu. The COF Trajectory is "grayed out" and

IP, Max and Delta
IP (Intercuspal Position)
When a new movie is recorded, or an existing movie is opened, it is
automatically advanced to the frame in which maximum
intercuspation occurs, or the largest area of tooth contact. The IP is a
useful reference for a number of common dental procedures. This
option takes into account only those forces that are above the noise
threshold (in the Recording Settings dialog) and the legend’s lower
limit. IP is only available when a Movie window is active, and is
unavailable when
"MAX" or "Delta" are
in effect.
In the image below,
the Movie is opened
and automatically
advances to the
frame in which maximum intercuspation occurs (IP). In
this example, IP occurs at 3.477 seconds into the Movie,
which is displayed on the Status Bar.
To disable this feature, open the Set User Preferences dialog (under the
"Options" menu), and uncheck the "Auto Intercuspal Position (IP)"
checkbox. When unchecked, any new movie that is recorded, or
existing movie that is opened, does not advance to the IP location.
Instead, the window opens to the first frame.
Max (Maximum Cumulative Force)
This allows the user to view the maximal force of closure for any bite
collected over a series of frames. It does this by displaying a composite
movie frame of the maximum force that each sensel reached over the
selected series of frames. Max allows the dentist to analyze both static
and dynamic data from a recording by providing a history of the highest
tooth contact forces on all teeth, and may be different from IP, which
represents only a single frame of a recording. Tooth contacts that may
have been transient interceptive contacts show up in Max but may not
be present in IP.
Max can be viewed for the entire movie or from the beginning of the
movie to the IP frame. Max is most useful when viewed over the series
of movie frames from the beginning of a closure to IP, and this is the
default ("From 1 -> IP"). To view the Max for the entire movie, open
the Set User Preferences dialog (under the "Options" menu) and under
"IP and Max," select "For Whole Movie."
08/01/07
T-Scan III User Manual (Rev L)
119
Max is only available when a Movie window is active. When it is enabled, the Movie window Status Bar displays "Max"
(for whole movie) or "Max IP" (for 1 -> IP), and the movie playback options are unavailable. If the COF Trajectory
display is enabled while Max is in effect, the trajectory for the entire range of frames is displayed. The Max option is
"toggled" on and off; when enabled, it has a checkmark beside it in the "View" menu.
Delta:
The Delta displays an image created by calculating the Max frame
from 1 to IP, then subtracting the IP frame. The Delta feature is
intended to identify the differences between the Max and IP movie
frames, and is used to demonstrate areas representing slides and
potential interceptive contacts otherwise difficult or impossible to
register. Perhaps the most clinically useful application of this option
is identifying differences in occlusal contacts during the guided
closure from centric relation to IP (CR-MIP slide). Many dentists
believe this analysis is key to understanding the health of the
occlusion, and Delta can clearly isolate these contacts for easy
identification.
Delta takes into account only those forces that are above the noise
threshold (in the Recording Settings dialog under the Options
menu) and the legend’s lower limit.
Delta is only available when a Movie window is active, and is unavailable when "Max" or "IP" are in effect. The Delta
option is "toggled" on and off; when enabled, it has a checkmark beside it in the menu, and the Movie Status Bar
displays "Max IP minus IP." The movie playback options are not available when Delta is selected.
The three figures below demonstrate the maximal force of a recorded closure from the beginning of the bite to IP (Max
- shown left), the frame showing IP and the Delta (shown center), or difference in tooth contacts between Max and IP
(shown right).
Arch Model, Table & Parameters
This section explains the concepts of the Arch Model, Arch Table and Arch Parameters.
Arch Model
The Arch Model Superimposes a model of the maxillary arch, as well as an "arch" outline on the tooth contact data in
the active 2-D Movie window. The Arch Model uses a combination of the contact energy outline of the 2-D Contour,
which defines the arch, and the proportionality of human teeth, to establish the tooth interface approximations across
the arch (source, Ash/Wheeler).
08/01/07
T-Scan III User Manual (Rev L)
120
The Arch Outline, which is drawn around the 2-D occlusal force image, provides some additional information for
analyzing your recordings. The Arch Model and Arch Outline are both saved with a movie file.
Arch Model enabled.
Arch Model disabled.
When a new movie is recorded, or an existing movie is opened, the
Arch Model is automatically displayed. This is the default setting. To
disable this behavior, go to the "Arch Model" tab in the "Set User
Preferences dialog (under the "Options" menu). The user can set the
following options.
•
Show Arch Model Automatically (New Real-Time Views):
With this option checked, a "Teeth Outline" (yellow trace) is
drawn around the 2-D occlusal force image automatically each
time a new Real-Time window is opened. When this option is
unchecked, no Arch lines are displayed.
•
Show Outline with Arch Model (All Views): With this option
checked, an "Arch Model" is always displayed.
•
Anterior/Posterior Default Position Multiplier: This factor is
used in the 2D Movie window when the "Anterior and
Posterior" icon is pressed, and the window is further subdivided into four quadrants (left and right, anterior
and posterior). The Central Incisor mm is multiplied by this factor to calculate the horizontal line default
position. The default is 2.15. A higher value moves the division line closer to the posterior, while a lower value
moves the line closer to the anterior.
Note: in order to view the Arch Model Outline, it must also be enabled (checked) under the "View"
menu ("View -> Arch Model").
Arch Model is only available when a Movie window is active. This option is "toggled" on and off; when it is enabled, it
has a checkmark beside it in the menu.
08/01/07
T-Scan III User Manual (Rev L)
121
When a recording (movie) is saved for the first time, the Arch Model is stored in the Patient Database. This Arch Model
is used for each new recording with this patient. Changing the Arch and saving this file as a new movie can save
revisions to this Arch Model. This brings up a prompt asking whether the new arch model should replace the existing
one in the database. Whenever a movie is opened that has a different Arch Model, there is a message asking whether the
new database arch should be used for this movie. To permanently save the new database arch to any existing movies,
you must re-save the movie with the new Arch Model using the Save As command (in the File menu) and replace the
original movie. Refer to Arch Parameters for more information on changing the Arch Model.
Embrasure Lines
The embrasure lines are the black lines that define tooth locations and follow the Arch Model. It is important to note
that the active region for each tooth is defined by a four-sided polygon that can be drawn from the end of each
embrasure line to the corresponding end of the embrasure lines on either side. In the image below left, the black lines
are the embrasure lines, while the red lines in the image below right denote a theoretical drawing of the active area for
the tooth. Note that the Red lines are purely theoretical, and will never be seen within the software. Any pressure sensed
outside this "Active" area is not included within any analysis.

Arch Table
The Arch Table opens additional Tabular data for the teeth within the
movie. This information can be changed or set by the user either prior to
recording (from a Real-time window) or post recording (within a Movie
window). The parameters that can be changed are displayed in white cells.
The data within gray cells cannot be changed. Clicking in any of the white
cell blocks places a green checkmark to note an enabled tooth parameter
within the Movie.
The following are the parameters outlined in the Arch Table: Missing
Closed, Missing Open, Implant, Bridge, Crown, Deciduous, Extra
Tooth, Pontic, and Removable Prosthetic. The Numbering System and
Tooth Width (mm) are automatically set by the software, and cannot be
changed or altered by the user.
Accessing the Arch Table
The Arch Table is automatically opened when a New Patient is created (shown below).
Note: If the Arch Table is closed, you cannot reopen it from the New Patient dialog. You can,
however, open it from the Real-time or 2-D Movie windows at any point in time after the patient is
created.
Note: If the Central Incisor Width is adjusted from the "New Patient" dialog, the Arch Table is not
automatically updated. However, once the patient is created and the Arch Table is opened from a
new Real-time window, the adjusted incisor width is displayed, and can be adjusted directly
within the Arch Table.
Note: Changing central incisor width will re-distribute tooth sizes.

Adjusting Tooth Positions and Properties
The positions and properties of individual teeth can be modified independently. The position of each tooth can be
adjusted by dragging the hash mark that separates each tooth. In addition, individual teeth can be labeled to mark
distinguishing features. Using the Arch Table, you can elect to mark specific teeth with these individual features by
clicking in the appropriate cells next to the tooth numbers.
Note: Right clicking on a tooth number also brings up a context-sensitive menu with a list of
features that can be applied to the tooth.
The following outlines the available features for marking each tooth:
•

Removable Prosthetic: Removable Prosthetic teeth are labeled by changing the tooth number to red. Tooth 12
is a Removable Prosthetic in the image below. Opening the Arch Table and clicking the "Removable Prosthetic"
cell for tooth 12 places a checkmark in the cell, noting that this tooth is a removable prosthetic. Clicking this
cell once again removes the checkmark and red label for the tooth.
Arch Parameters
Once in place, the Arch Model can be fine-tuned to best fit the patient’s teeth.
The proportions of the teeth in the Arch Model are based on the rule of golden proportions in reference to the width of
the Central Incisors. Increasing or decreasing the "Central Incisor width" field changes the proportions of all teeth. TScan III selects a default Central Incisor width of 8.5 mm, which automatically addresses the majority of the
population. The following procedure should be followed in order to adjust the Patient's Arch Model Parameters.

1. Before changing the Arch Parameters, make sure that Arch Model is enabled under
the "View" menu (shown at right). Also make sure the 2-D Movie window is active by
clicking on its Title Bar. The Title Bar is highlighted in blue.
2. Select Arch Parameters (located under the View menu - shown at right). This opens a dialog for the active
Movie window, from which you can either adjust the
patient’s Arch Model, or import an arch model from a
previous recording.
3. After measuring the patient’s incisor with your Iawanson
gauge, enter this value by clicking the up or down
arrows next to the "Central Incisor width" field (shown
below left). Note that the Arch Model changes instantly
so you can observe the new Arch Model directly onscreen. The standard deviations of +1 and -1 are +0.5
mm and -0.5 mm; this range of 11 positions in 0.1 mm
steps (8.0 to 9.0 mm) covers nearly 90% of the population.
Tooth Numbering
Systems
Once the arch
model has been
created, the teeth
can be labeled
using three
common
numbering systems
within the
"Numbering
System" tab on the Set User Preferences dialog (under the Options
menu). These options are outlined below.
•
Display Numbering System: If no checkmark is placed in
this box, the numbering system is turned off and all options
within this tab are "grayed out." The Movie window does not
display any numbering system for tooth location. Placing a
checkmark in this box opens up the other options on this tab
and displays numbers next to each tooth location within the
Movie window.
The image at left displays the Movie window without any
Numbering System applied.

To Import Arch Model Parameters from a previously recorded movie, click the "From External File" radio button. You
can then either type the stored movie’s file name and entire path in the "File Name" field, or click the Browse button.
The Browse button launches the "Open" dialog where you can select the original file’s name and location (shown
below).
ADDING A LINE
A Line can be placed into an open Movie or Real-time window, and used to measure the distance between two specific
points on the sensor. This option is a very useful tool that allows you to quickly determine dimensions inside the mouth.
Adding a Line to a Window
The following procedure can be used to add a Line to the Movie or Real-time window.
Note: up to 4 Lines can be added to any Real-time or Movie window.
1. Select Add Line from the View menu. You may also click the right mouse button while the cursor is over a
window, and select "Add Line."
Selecting "Add Line" from the "View" menu.
Selecting "Add Line" from the right-click contextsensitive menu.
2. When Add Line is selected, the "Line" symbol is added to the cursor over a Real-time or Movie window. Click
the mouse in the desired window, and a gray Line is placed at that point. The actual distance (on the sensor)
between the Line’s endpoints is displayed at the midpoint of the line.

GRAPHS
T-Scan III graphing features provide a simple way to study bilateral occlusal force relationships. The force percentage
display enables you to compare the left / right balance of an occlusion in a recording. This feature also provides the
dentist with a better understanding of the timing of occlusal events, such as total time for closure in IP and disclusion
time. The graphing option is unavailable when 3-D Columns mode is in effect.
Note: You cannot create a graph for a Real-time window .
Displaying a graph
A graph is automatically displayed when you record a movie or open a previously recorded movie file. To turn off the
graph, you must uncheck Graph in the "View" menu, or click the Show Graph icon on the 2-D Movie window Toolbar
to disable the graph for the active Movie window.
To show or hide the Graph display,
click "Graph" from the "View" menu.
Alternately, the user can click the
"Show Graph" icon on the 2-D Movie
window Toolbar.
When a graph is automatically created, two things happen:
•
The "active" Real-time or Movie window is divided into two equal-colored boxes (one red and one green)
about the mid-sagittal plane
•
The Graph Window displays a graph, which compares left versus right side occlusion, shown as a percentage
of the total force for an entire movie. The graph includes color-coded traces, which represent the percentage of
Maximum Force (represented by the gray line), as well as the forces inside the two equal colored boxes in the
active Movie window (green for left side and red for right side). This is outlined in the figure below.
08/01/07
T-Scan III User Manual (Rev L)
133
Graph Data
The graph displays the Relative Force (% of Total Force) for the left and right sides vs. Time (in seconds), for the
entire movie. A vertical "time line" marks the elapsed time, and current movie frame, at which the force percentages
inside the two colored boxes are being displayed.
The information to the right of the graph includes the following:
•
The "% of Maximum Force." This is noted on the graph by a gray trace that shows the force at that "time line"
position (frame) as a percentage of the total force. The "total force" is calculated by adding the left and right
force values for a frame. This gray "trace" is on by default, but may be disabled by deselecting "Show Total
Force" under the "Graph" tab in the Set User Preferences dialog (under the Options menu). Refer to the Graph
Preferences section for further information.
•
The amount of time from the start of the "A" Line (OT-A) to the ending "B" Line (OT-B), in seconds.
•
The location of the graph, denoted by a vertical solid black time line. This marks the elapsed time, and current
movie frame, at which the force percentages inside the two colored boxes in the 2-D Movie window are being
displayed. In other words, this is the location of the graph, which is in synch with the 2-D Movie window. Just
below the elapsed time are the force percentages for the left (green) and right (red) sides for any specific
movie frame. An ideal occlusion would have 50% of the occlusal force on the left side and 50% on the right
during a normal closure.
08/01/07
T-Scan III User Manual (Rev L)
134
To lock the timeline, click the Time in the 2-D Movie window Status Bar. The time turns red. This locks the
Timeline in the Graph. When you attempt to move the line, it snaps back into position.
A-B / C-D Increment/Differential Lines
The dashed lines marked "A" and "B" in the graph defines the "A-B Increment/Differential" lines. There are also two
other lines that can be added to the graph ("C" and "D"). These additional two lines can be added by selecting "Show CD Increment/Differential" in the "Graph" tab of the "Set User Preferences" dialog (under the "Options" menu). For more
information, refer to the Graph Preferences section.
These lines are used to mark two separate sets of positions (frames) of the movie. The A-B Increment/Differential lines
can be used to denote the start and end of the Occlusion Time (OT-A and OT-B) and the C-D Increment/Differential
lines can be used to denote the start and end of the Disclusion Time (DT-C and DT-D). To the right of the graph, the
elapsed times are noted.
The image at right
shows the Differential
lines (note: these lines
are called Differential
lines when using IP
recording mode).
The image below shows the Increment lines (note: these lines are called Increment lines when
using CR recording mode).

"Disclusion Time" (a term coined by Dr. Robert B. Kerstein, DMD) is the length of time that the posterior teeth, the
molars and premolars, are engaged and meshed together during the chewing function. The longer this time of meshing,
the longer the posterior teeth push against each other and compress each other into their tooth sockets, causing a
number of TMJ disorders.
Moving the Incremental/Differential lines
To move one of the Increment/Differential lines, simply place your mouse cursor over it. The mouse cursor changes
to a double-sided arrow. Click and drag the two-way arrow to the desired position. When these lines are moved, the
corresponding numerical values to the right of the graph are updated automatically.
Note: Be careful not to confuse the Timeline with the Increment/Differential lines. The Timeline is
solid, while the Increment/DIfferential lines are dashed.
Anterior and Posterior
Clicking on the Anterior & Posterior icon on the 2-D Movie window
Toolbar adds two additional Graph traces in the Graph window. These
are also color-coded and their output (Time) is displayed on the right
side of the Graph window.
Clicking the
Anterior and
Posterior icon
separates the
Movie window into
quadrants (shown
at right).
If you want to
change the size of
these four
quadrants, you can place the cursor at the intersection (center
point). A four-way arrow appears. Click and drag the center point in
any direction, and let go of the mouse when the quadrants are in the
desired position (shown at left).
Once the Movie is subdivided into quadrants, they are displayed
within the Graph window as shown below. Each trace is color-coded for the corresponding section of the window, and
the output is displayed on the right side of the Graph.
08/01/07
T-Scan III User Manual (Rev L)

The Anterior/Posterior line is positioned automatically. The default value is 2.15. This value can be changed within the
"Arch Parameters" tab of the Set User Preferences dialog. Refer to this section for further information on how to adjust
settings for the Anterior/Posterior functionality.
Graph Preferences
Graph options can be set up under the Set User Preferences dialog (under the Options menu). The following "Graph"
tab parameters are outlined below.
•
Show Total Force: When checked, the total force (gray trace)
is depicted in the graph, and the “% of Total Force” value is
displayed to the right of the graph.
•
Show A-B Increment/Differential: Shows two dotted lines (A
and B) which can be used to measure locations along the Xaxis of the graph. These lines are moveable by clicking and
dragging them to the desired location.
•
Show C-D Increment/Differential: Shows two additional
dotted lines (C and D) which can be used to measure locations
along the X-axis of the graph. These lines are moveable by
clicking and dragging them to the desired location.
The following shows all four lines within a Graph window.
Note that the exact location of the lines along the X-axis is
reported on the right side of the Graph window.

Manipulating the Graph
Changing the Size of the Graph Window
The main Graph window can be resized to any size you desire by
clicking and dragging on the outer edges of the Graph window.
In the same way, if the information on the right side of the
Graph window is not fully visible, this area can be expanded by
dragging (with the cursor) the line that separates it from the
actual graph.
Moving the Location of the "Time Line"
You can observe both the "time line" and the occlusal force values to the right change in unison as you play back a
recording. This allows the clinician to view the timing of occlusal events, and to see the force percentages for the left
and right sides for any specific movie frame.
The "time line" can also be dragged to any position (time) within the graph, and the corresponding movie also moves to
that frame. To move the "time line," place the mouse cursor over it. A two-way arrow appears, and the line can be
dragged in either direction.
You can also click anywhere in the graph (careful not to click on any increment lines), and the "time line" instantly
jumps to that point. When the "time line" is moved, numerical values to the right of the graph are also updated. If the
accompanying 2-D Movie window is paused, the "time line" is also paused, and you will not be able to move it.
To move one of the "A-B Increment" lines, place your mouse cursor over it, and drag the two-way arrow to the desired
position in the same manner as moving the "time line." When these lines are moved, the corresponding numerical
values to the right of the graph are updated automatically.
08/01/07
T-Scan III User Manual (Rev L)
138
Moving the Location of the Left and Right Boxes
You may also want to change the size of the left and right boxes in the Movie window. To do this, place the cursor on the
line that divides the boxes; a two-way arrow appears, and that line can be dragged in either direction. To remove one of
the boxes completely, drag the line all the way to the edge of the window and let go of the mouse. The graph is
automatically updated.
To move the box, click and drag from one location to the other. Notice the graph in the initial
position (below right)
Once the box is moved, the graph updates with new information for the left and right positions.
You can also divide the Movie window into four boxes. Refer to the Anterior and Posterior section for further
information on how to do this.
You can also dock and undock graph windows. Refer to the Smart Docking section for further information.

Closing/Opening a Graph from the Context Menu
You can utilize the right-click context menu to open and close a graph as well as to delete it. Hover your mouse over the
2-D Movie window's Left/Right division line. The cursor becomes a two-way arrow. Right click and select Graphs to
uncheck it (by default this is checked, meaning the Graph and Graph Zoom windows are displayed). When unchecked,
the 2-D window division line switches to gray and the Graph and Graph Zoom windows are closed. Right click over the
gray division line and click Graphs again to bring back both Graph and Zoom Graph windows.
Uncheck Graphs in the 2-D Movie window's division line context menu.
This results in removal of the Graph and Graph Zoom windows, but maintains the division line
and left/right boxes.

To delete the Graph from the right-click context menu select Delete. A warning message asks if you are sure you want to
remove the selected object. Click OK. This removes the Graph and Graph Zoom windows, and also removes the division
line (and left/right boxes) from the 2-D Movie Window. To access the Graph and Graph Zoom windows at this point,
click the Show Graph icon on the 2-D Movie window toolbar.
Click Delete from the 2-D Movie window's division line context menu.
A message asks if you are certain you want to delete the selected object. Click "OK."
This results in the Graph and Graph Zoom window being removed, as well as the division line and
left/right boxes in the 2-D Movie window.
08/01/07
T-Scan III User Manual (Rev L)
141
Closing a graph
To close a graph window, select Graph from the View menu, or click the Show Graph icon in the 2-D Movie window.
You can also close a graph by clicking the ‘X’ in the top right corner of the Graph window’s Title Bar.
Note: A graph will close automatically if the corresponding 2-D Movie window is closed.
Note: Closing the "Graph" window automatically closes the "Graph Zoom" window as well. Closing
the "Graph Zoom" window does not close any other open windows. To make the "Graph Zoom"
window visible again, toggle "Graph" from the "View" menu twice, or click the "Show Graph" icon
in the 2-D Movie window twice (first to close the graph and then again to open it once more).
Graph Zoom
The Graph Zoom acts as a secondary graph that displays a zoomedin view of the Main Graph window. The Graph Zoom cannot be
enlarged or reduced in size and is permanently fixed to display 1.5
seconds of the main Graph window. As most occlusal force activity
occurs and is captured in a very short duration of time with a lot of
activity, it is sometimes difficult to view the subtle nuances that
occur in the Graph window. This is where the Graph Zoom can be
useful to display activity down to the millisecond. It provides a
high-resolution view of activity that is occurring within the main
Graph during this short duration.
Moving the black time line in either direction within the Graph window dynamically updates the time line in the Graph
Zoom window. This aids the user to target and hone in on a specific area of the Movie. Think of the Graph window as a
large-scale map of the Movie, and the Graph Zoom is the smaller Inset map which displays a detailed view of a specific
area of the Movie.
Smart Docking
You can also dock and undock the Graph Zoom window. Refer to the Smart Docking section for further information.
Resizing the Graph Zoom window
To resize the window, click and drag from any side or corner of the window. The aspect ratio of the Graph Zoom
window is fixed and always maintained, no matter what size it becomes. This means both the height and width of the
window is changed at once. You cannot change one without changing the other.

COPY & EXPORT OPTIONS
COPY OPTIONS
Note: For further information on how to export information from Tekscan software into other
software applications, please refer to the “Copy & Export Options” section found in your system
software Help File under the “Help” menu.
T-Scan III provides a number of copy options that allow you to compare movie frames, create reports or documents
using actual color “movie” frames, and view the window information in a spreadsheet or word processing program.
The Copy command saves the currently “active” Real-time window, 2-D or 3-D Movie Frame, Graph, or Graph Zoom to
the MS Windows clipboard as an image (bitmap). At the same time, some general text information relating to the
window, including the window name, date and time, sensor information, time between frames, header information, and
comments, is also transferred to the clipboard. When you want to paste this information from the clipboard into another
document, select Edit>>Paste Special in that program, and then select either “bitmap” or “text” to get the data in the
desired form.
You may copy T-Scan III window data using one of the following methods:
1. To copy an entire 2-D or 3-D Movie, Real-time, Graph or Graph Zoom window: Click on the desired
window to make it “active.” Select Copy from the Edit menu (or click the corresponding Toolbar icon), or
click the right mouse button while the cursor is above the window and select Copy. The “active” window is
copied as an image (bitmap), and its header information will be copied as a text file, to the MS Windows
clipboard.
2. To copy only a specific area of a Movie or Real-time window: Position the mouse pointer at one corner of
the region to be copied. Click and hold down the left mouse button, and drag the cursor to the other edge of
the region to copy; a selection box will be drawn around the area, and a prompt opens asking if you would like
to keep the Copy Box. Click Yes. After a selection box has been created, it may be moved or resized by clicking
on its border and dragging to the new location, or clicking on a resize handle and dragging to the desired size.
Note that the mouse cursor changes shape to a double-sided arrow or four way arrow to indicate the allowable
actions.
Once the selection box is in place, select Copy from the “Edit” menu (or click the corresponding Toolbar
icon), or click the right mouse button while the cursor is over the window and select Copy. The area inside the
selection box is copied as an image (bitmap), and the window’s header information is copied as a text file, to
the MS Windows clipboard. Press the “Delete” key on your keyboard to remove the selection box.
3. To copy the Legend: Right mouse click anywhere on the Legend (color scale), and select Copy. The legend is
copied to the clipboard as an image (bitmap) only. The Copy command in the “Edit” menu does not affect the
Legend.
4. To copy the entire screen: Press the “Print Screen” key on your computer’s keyboard. A picture of the entire
screen, including any open 2-D or 3-D Movie windows, Real-time window, or Graph and Graph Zoom
windows, as well as the Toolbar and Menu, are placed into the Windows clipboard as an image (bitmap) only.
From there, you can paste this image into any other compatible program.

PRINTING
The Print function allows you to print the contents of the currently active Movie window, including comments and
graphs, to any of the hundreds of printers which MS Windows supports. The window is printed exactly as it appears onscreen, and includes the options selected in Print Setup.
PRINT SETUP
Print Setup allows you to select parameters to generate a final output of your T-Scan III movie along with Graphs and
Comments to a printer. Follow the instructions below to select your print options.
1. Select Print Setup from the File menu.
Print Setup gives you a number of options on how your printed page will
look. Most of the options are standard MS Windows printing options.
2. In the "Content" section, you can specify
exactly what will appear on the printout.
You make selections by clicking on an
option. A checkmark is placed to the left
of your choice. Unavailable options are
"grayed out." Each of these options is
described below:
Note: By
default, all
available
"Content"
options are
enabled
(checked), and
will print along with the "active" movie.
•
Fields: Prints any fields that were entered under Comments in the File menu, as well as the standard
patient fields (patient’s first, last, and middle name, patient ID, gender, and date of birth). Refer to the
Including Comments with a Recording section for more information on entering and changing fields.
•
Comments: Prints the comments that were entered under Comments in the File menu. In addition, if the
movie is "marked by procedure," the procedure name is listed in the header information. Refer to the
"Including Comments with a Recording" section for more information on comments, and the Marking a
Movie by Diagnosis or Procedure section for information on how to "mark" movies by procedure.
•
View: Prints the contents of the selected 2-D Movie window. If this option is not selected, no occlusal
force (sensor) data is printed.
•
Graph: Prints any graphs that correspond to an "active" 2-D Movie window (it is unavailable when a Realtime window is "active"). When this option is selected, the Graph is listed to the left. You can click on the
name of the graph to select (highlight) or deselect it for printing.
Note: If a graph does not print, or is not visible in the Print Preview, check the "Graph" Print Setup option.
•
08/01/07
Photo: Prints the associated Photo that is linked to the Movie. Refer to Linking a Photo to a Movie Frame
for further information.

There are also view options located at the bottom right of the dialog called "Scaling the
View." Select your choice based on your preference. These two options are outlined
below.
•
Fit on Page or Scale: These selections are mutually exclusive for a window. If
Fit on Page is selected (default), the size of the image will be set to the largest
printable area. If Scale is selected, you may enter the percentage of the actual
sensor that is displayed.
3. When you are satisfied with the Print Setup, click OK. Then select Print
Preview from the "File" menu, to see how your printout will look.
If some information is missing or you wish to make any other Print
Setup changes, close out of the Print Preview, and make any necessary adjustments in the Print Setup dialog (as
outlined in step 2 above).
The following displays a typical Print Preview screen.
08/01/07
T-Scan III User Manual (Rev L)

4. Select Print from the "File" menu (shown at right).
Enter any Printer-specific options. As printers vary, your make and
model will most likely be different than the one shown here. Consult your
printer's documentation for an explanation of your printer's options.
When you are ready to Print, click the OK button in your "Print" dialog.
If you receive an error message while printing, or printing does not begin in a timely manner, close any Realtime windows and/or stop recording data. If printing does not resume immediately, re-send the print job to
your printer. If you are still having problems, consult your Printer's documentation.
PRINTING GRAYSCALE
The T-Scan III software also allows you to print the color screen display as a grayscale image. When a grayscale (noncolor) printer is installed, and is selected as the default printer (in the Print Setup or "Print" options in the File menu),
the image is printed in grayscale.
In color printouts, the color scale (legend) goes from blue (lowest forces) to red (highest forces). The T-Scan III
software does not simply print these colors in black and white, because red and blue will both print dark and appear to
be at the same force.
When printing grayscale, the software automatically adjusts the Legend to divide the 13 possible force ranges into 13
shades of gray, going from light (low forces) to dark (high forces). The corresponding areas on the printout of the
display window is adjusted to agree with the Legend. In this way, the differences in occlusal force are much more easily
discerned.
Note: This option is intended for grayscale printers, and may not work correctly if printing to a
color printer, with the "print grayscale" option selected in your printer driver dialog. If you are in
doubt whether or not you have a grayscale printer, consult your printer's documentation.

APPENDIX A: BACKGROUND FOR COF ANALYSIS
This section provides further background for analyzing the Center of Force.
HOW THE CENTER OF FORCE IS CALCULATED
The location of the Center of Force marker is determined by calculating the sum of the medio-lateral force moment of
the tooth contacts about the mid-sagittal axis, and the mean of the left and right leverage arms in relation to the incisive
plane, according to the following formulas:
Left-Right Moment = Sum (contact force x contact distance right) - (contact force x contact distance left) and is
displayed in Newton-millimeters (N-mm).
The anterior-posterior location of the COF marker is found by calculating the left lever and right lever statistics from the
incisal plane as follows:
Left Lever = Sum (force at contact x distance from the incisal plane) / Sum (left contacts), displayed in millimeters.
Similarly the right lever is calculated, and the mean of the left and right leverage arms gives the average anteriorposterior distance of the marker from the incisive plane, which is described by the following formula:
Mean L-R lever = Right lever + Left lever / 2
These statistics allow the practitioner to identify the location of the Center of Force for any bite automatically by selecting
the COF option from the View menu.
RATIONALE FOR CENTER OF FORCE TARGET
The rationale for the COF target came from the work of Maness, et al, who described the mean location of the
distribution of occlusal contacts in maximum intercuspation; and from Mizui, et al, who quantified occlusal force in the
intercuspal position. Both investigators described a left-right balance of occlusal contacts about the mid-sagittal plane
with the center of the COF target located approximately in the region representing the mesial aspect of the first molar.
Maness, et al, identified the anterior-posterior center of the distribution of contacts in maximum intercuspation as 28
mm. distal to the incisal plane and Mizui, et al found the center at approximately 34 mm. The mean of these measures,
31 mm., represents the center of the target on the mid-sagittal plane and is used as an approximation of the ideal
location of the Center of Force in a normal subject.
The size of the target is taken from the standard deviation of the anterior-posterior and medio-lateral measure of the
distribution of occlusal contacts described by Maness, and is 7.65 mm. and 6.48 mm., respectively. These dimensions
describe an ellipse with a radius represented by two standard deviations, which describes 68% and 95% of normal
subjects. The center of the target lies approximately 31 millimeters distal from the incisal plane. This is the location of
the Center of Force target and is used as an approximation of the ideal location of the center of force in a normal
subject.
It must be emphasized that this analysis is provided to the dentist as an estimate of normal and the dentist must
determine the significance of the data in relation to other pertinent facts.

APPENDIX B: USING THE EXTERNAL TRIGGER & TRIG-SYNCH BOX
As an option, you may purchase additional software that will enable your Tekscan system to receive an external signal
recording. The trigger box was developed to provide this trigger signal so that the user can synchronize more than one
file. These two can also be used in combination with the optional software feature video playback to synchronize the
digital video (*.avi, *.mpg, *.mpeg, *.mp2, *.mps, *.mpe) with the pressure data from a Tekscan system.
Note: The external trigger cannot be used concurrently with the Synchronizing Pulse because they
use the same serial (COM) port.
SETTING UP THE SOFTWARE FOR EXTERNAL TRIGGERING
1. Select Acquisition Parameters from the
Options pull-down menu. This will bring up
the Data Acquisition Parameters dialog box
(shown at right).
2. Click in the check box to Enable Triggering.
The Triggering button, on the right side of the
dialog box, will become available.
3. Click the 'Triggering' button on the right side
of the dialog box. This brings up the
'Triggering' dialog box (below).
4. In the 'Start Triggering’ dialog box, select ‘External’ as the Start
Method. When the software receives input from the COM
(serial) port, recording begins.
5. In the 'Stop Triggering' area, select 'Frame count,' 'Last
contact,' 'External,' or 'None' as the Stop Method.
Select ‘Frame Count’ if you wish the software to stop when it
has recorded the set number of frames. If you select this
option, you must enter the frame count in the Triggering dialog
box under ‘Stop Frame Count.’ If you enter a different number
of frames in this field than what was entered in the Data
Acquisition Parameters dialog box, the software will stop recording at the Frame Count you entered under
Triggering.
Select ‘External’ if the software will receive an external signal to stop recording from a device attached to your
computer.
Select ‘None’ if you wish to stop recording manually, or if you want the entire movie as specified in the Data
Acquisition Parameters dialog box to be recorded. When None is selected, recording will stop only when you
select Stop from the Movie pull-down menu, click on the Stop icon in the Toolbar, press <F4> on your
keyboard, or the correct number of frames (as entered in the 'Frames to Record' field) have been recorded.
6. When you are satisfied with your choices, click 'OK' to return to the Data Acquisition Parameters dialog box.
7. In the Data Acquisition Parameters dialog box, click 'OK' to accept and save your settings.
08/01/07
T-Scan III User Manual (Rev L)

8. Once a recording is initiated by the user (by selecting Record or Snapshot from the Main Menu or Toolbar),
pressure data collection will not start until the start trigger event occurs. If no frames of data have been
collected (i.e.: no trigger event was received), and recording is stopped, the system will revert to Real-time
mode.
9. The recording will stop when specified by the ‘Stop Triggering’ event selections. If you wish to stop recording
manually, select Stop from the Movie menu, click on the Stop icon in the Toolbar, or press the <F4> key on
your keyboard.
The TS-100 box is used to generate an external trigger to be transmitted to the Tekscan software. The TS-100 can be
used in one of three ways:
1. The Trigger switch can be pushed by hand to trigger a recording.
2. External devices (such as an electric eye or light beam) can be connected to generate input that will trigger
recording in the software.
3. External devices can be connected to receive output from the trigger box for other data gathering purposes.
Each time the trigger is pushed, the TS-100 generates a single pulse to connected devices. Pushing the button
more than once, or having the inputs generate multiple square waves, will generate multiple pulses to the
outputs on the trigger box.
INSTALLING THE TS-100 HARDWARE ON YOUR SYSTEM
1. Enable External Triggering in the Tekscan software (as described above).
2. Exit the Tekscan software.
3. Connect the serial cable to the serial port you selected when enabling external triggering. When the TS-100 is
connected to the computer via the serial port, the batteries are being charged.
4. Connect the other end of the cable to the 'To Serial Port' terminal on the Trig-Synch box.
5. Plug in the External LED cable.
6.
(Optional) Plug in the External Power cord. The included external power supply can be used to power the box
when the batteries are low. In addition, the external power supply will recharge the batteries.
7.
(Optional) Plug in any other positive or negative Inputs to the channels labeled either 'Negative Input' or
'Positive Input.' Connecting other inputs will activate the trigger instead of using the trigger switch.
8.
(Optional) Plug in any other positive or negative Outputs to the channels labeled either 'Negative Output' or
'Positive Output.' The TS-100 will generate one pulse to these outputs each time the button is depressed or
each time an input device generates a square wave.
9. Toggle the power switch to ‘On’. The power indicator should light.

10. Restart the Tekscan software.
Negative Input: Connecting this channel to
ground will activate the trigger instead of using
the Trigger Switch.
Positive Input: Supplying +4V to this channel
will activate the trigger instead of using the
Trigger Switch.
Positive Output: This channel initially produces
a 0V output and then rises to a +4 output when
the trigger is activated.
Negative Output: This channel initially
produces a +4V output and falls to a 0V output
when the trigger is activated.

APPENDIX C: VIDEO FEATURES
The video software will enable you to record a video of your test at the same time you record pressure data using the
Tekscan sensor. The Tekscan software enables you to import video information for review and analysis side by side with
recorded pressure data. Synchronization of a physical image with the pressure data can aid in analyzing pressure data
created by ordinary movements during the test. Before a video can be recorded, the software must be set up for External
Triggering. However, External Triggering and Pre-triggering (if available for your software) cannot be used
concurrently. If you have purchased the video option, your Toolbar will have additional buttons.
Important: To use these features with the Tekscan software, you must have an open COM (serial)
port and Windows Media version 6.4 or higher. Tekscan recommends the use of the Tekscan TrigSync (TS-100) box for this feature.
USING THE TRIG-SYNCH BOX TO TAKE A VIDEO
1. To operate the TS-100 by hand as an external trigger, set up your camera so that both the test area and the LED
are within the camera's field of view.
2. Start the camera recording video information before triggering movie recording with the software.
3. When you are ready to start recording seating pressure data, push the trigger Switch. The LED will come on and
the software will begin recording. The LED signal visible in the video can later be used to synchronize the video
with the movie data recorded by the software.
4. Once the video has been recorded, it can be edited using the Video Functions.
Note: Be sure to save the movie data that was recorded at the same time as the video. Videos
recorded by the external video camera must be saved separately.
USING VIDEO OPTIONS TO ANALYZE PRESSURE DATA
Before the Tekscan software can use a video, the video must be converted to a digital movie and stored on your
computer. The software can use any of the following file extensions: *.avi, *.mpg, *.mpeg, *.mp2, *.mps, *.mpe.
Videos are linked together by time, not by the content of the video and movies. When saving your videos, be sure to
name them descriptively so that the videos can later be linked to the correct seating pressure movie. If a pressure data
movie is opened first, any video opened in the software will be linked to the movie, regardless of whether or not the
video is related to the movie of pressure data.
Note that the buttons in the Toolbar and the VCR buttons in the video window affect both the movie and video if they are
linked. If the movie and video are unlinked, the Toolbar buttons operate only the movie of pressure data, while the VCR
buttons in the video window affect only the video. Additionally, the Toolbar buttons
play frames at the rate specified in the Acquisition Parameters dialog box. The VCR
buttons in the video window play the frames at the acquisition rate of the video
camera used to record the video.
Opening a Linked Video
1. Open the .fsx movie file of seating pressure data that you wish to
synchronize with the video.
2. Using one of the three buttons (right) on the Toolbar, open the video.

until you are satisfied.
7. Scroll the movie until you have reached the start point.
8. Click "Cut Beginning” button. This brings up the Video dialog (at right).
Select one of the Compressors from the pull-down menu. The quality of
your video will depend both on the original compression used when your video was converted to digital format
and saved on your computer, as well as on the decompression you select when editing the video. In general,
the higher the compression, the smaller the file but the lower the quality of the video playback. The lower the
compression, the higher the quality of the video playback, but the larger the file. If your system has the
capacity, Tekscan recommends selecting Full Frames (Uncompressed). If you must select compression,
Tekscan recommends “DV Video Encoder,” “Microsoft Video 1,” or “Indeo.” Microsoft Video 1 comes with
Windows; Indeo is a video compression and decompression program available free of charge from Ligos.
Indeo's video compression and decompression software maintains high quality video playback while still
providing high compression of the file. It is downloadable at:
http://www.ligos.com/index.phtml?n1=products&n2=indeo&n3=video
If you select compression, you will be able to enter more settings. Compression Quality also affects quality of
the video. The higher the number selected, the better the quality and the larger the size of the file. If the
number selected is smaller, quality of the video will be degraded, but the file will be smaller. If your computer
is having difficulty playing the video, select a smaller compression number. When you select compression, the
Configure button will become available. Tekscan recommends that you leave the settings at the defaults. If you
make a mistake, click the 'Reload Original Video' button on the VCR bar in the video window.
9. Click the 'Save Video' or 'Save Video As' button to save your edited video.
10. If you have reached the end of the recorded seating pressure data, but the video is still playing, the excess video
can also be removed. Play the linked movie and video until the end of the movie. Use the scroll bar at the
bottom of the video window to scroll the video if necessary.
11. Click the 'Mark End Point' button on the VCR bar in the video window.
12. Play the movie and video to check that you have marked the end point correctly.
When you are satisfied, click the 'Cut the Rest' button on the VCR bar in the video window. This will again bring
up the Video Compression dialog box. Select one of the Compressors from the pull-down menu. Select the
same Compressor that you chose when you cut the beginning frames. If you make a mistake, click the 'Reload
Original Video' button on the VCR bar in the video window.
13. Click the 'Save Video' or 'Save Video As' button to save your edited video.

APPENDIX D: BIORESEARCH INTEGRATION MODULE
The BioEMG Integration Software synchronizes and integrates the data from the T-Scan III with electromyography data
of the BioEMG module. The following instructions are on how to operate the additional synchronization and integration
features included in the Integration Software. Otherwise, both systems function the same as in the non-integrated
version. If you need information on how to operate either system, please refer to their respective manuals.
USING THE BIOEMG INTEGRATION MODULE
Activating the Integration mode
To be in the integration mode, you must start the corresponding program by clicking the BioEMG icon in the T-Scan
III program’s main menu bar or by clicking the T-Scan III icon in the BioEMG program.
To acquire integrated data, the operator can do any of the following:
1. Activate BioEMG from the T-Scan III program by clicking the BioEMG icon on the main menu bar.
2. Activate the T-Scan III program from the BioEMG program by clicking the T-Scan III icon after you have
selected an existing patient or entered new patient data.
3. Once both programs are active by clicking on the integration icon, the recording procedures are the same as if
you were using the programs independently.
Note: When using the Integration module, the “trigger sensor” feature is not available. The systems
will start recording when “Recording” is activated.
Note: The default recording time is 30 seconds. This period can be changed within the "Data
Acquisition Parameters" dialog under the "Options" menu in the T-Scan III program.
Saving integrated data
When you save integrated data from either program, the data automatically saves in the other program if both files are
open at the initial time of saving the data.
Note: If you include comments and procedures in an integrated file, they are saved in both programs.
Comments feature
When you initially save a file, the comment text
strings are shared between the programs. This
ensures the same message in the corresponding
file of both BioEMG and T-Scan III. Comments,
changed after initially saving a file in one
program, will not automatically update in the
other program. In this case, if you need the same
text in the other program, you will need to make
the change manually in the other program.
The T-Scan III procedure line is automatically
passed into the BioEMG comment line. Editing
the "quick entry" comment list in either program will not automatically update the "quick entry" list in the other
program. If you need the same "quick entry" list in the other program, the change needs to be made manually.

163
Closing integrated files
If you are closing an un-saved recording of simultaneously acquired data, it closes both the T-Scan III and BioEMG
recordings simultaneously. If you are reviewing saved integrated data in both programs, the files will need to be closed
individually.
Identifying corresponding integrated data files in either program
T-Scan III files that have corresponding BioEMG files are automatically labeled with EMG in the procedure line.
Screen layout in integration mode
By default in the integration mode, both programs are tiled vertically. You can change this setting to horizontal by going
into Options -> Settings and clicking on the "View Settings" tab.
The following shows an image of the integration between the T-Scan III program on the right and the BioEMG module
on the left.

T-Scan III User Manual (Rev L)
164
Changing recording time
1. The integration module has a 10 second default recording time.
2. This setting can be changed in both programs. If you change the setting in one program, you should change it
in the other.
3. To change the recording time for the:
•
T-Scan II: go to Options -> Acquisition Parameters. Change the setting within the "BioPAK recording
time" field.
•
BioEMG: see the preset section of the BioEMG operator manual.
Time synchronization
The cursor of the T-Scan III graph and the BioEMG raw data window are synchronized. Changing the cursor position
in either program will synchronize the cursor position in the corresponding program.
Reviewing files
When the integration mode is active (see “Activating the Integration Mode” above), opening an integrated file in one
program will open the corresponding file in the other program.
Ordering the T-Scan III - BioEMG Integration Software
If you do not have the T-Scan III - BioEMG Integration Software and are considering a purchase, please note that the
Integration Software consists of two pieces:
1. The first piece is an additional optional feature that needs to be ordered and added to the T-Scan III software.
2. The second piece is the additional BioEMG optional feature that needs to be ordered from BioResearch.
In addition, you will need to upgrade your software(s) to be compatible. The integration mode requires T-Scan III
version 4.0 or later and BioEMG version 2.1 or later.

BRIDGING THE TEKSCAN DATABASE WITH OTHER APPLICATIONS
The following guidelines are for users interested in having an alternate application open an existing patient or create a
new patient within the Tekscan patient database.
Introduction
Tekscan has a simple command line interface so that other programs can start the Tekscan software and send across a
limited amount of patient information necessary to create the patient in our database or open an existing patient in our
database. Thereafter, whenever the link button is executed in the user's application, it will start the Tekscan software
and open the active patient’s record in Tekscan. The user can then continue with a recording or analysis in Tekscan.
This ability is included in the Tekscan software, and does not require any additional module or add-on. It would,
however, require a button in the corresponding software to activate and pass the information to Tekscan.
Example
The following example illustrates opening John Smith's patient record using the T-Scan III Tekscan software:
1. Go to Start -> Run. The "Run" dialog opens.
2. Type C:\tekscan\tscan2\tscan.exe -lSmith -fJohn -i123, for example. Alternately you can right-click on the
Tscan icon on your desktop and select Properties. Navigate to the shortcut tab and type
C:\tekscan\tscan2\tscan.exe -lSmith -fJohn -i123 in the "Target" field.
3. Execute the command, and the Tekscan software searches through the database. If John Smith is found in the
database, then John Smith's patient record opens on-screen. If John Smith is not found in the database, then a
new patient record is created for John Smith, and this new patient record opens on-screen.
Command Line Parameters
You can pass the following parameters in the command line when you start the Tekscan software executable:
tscan.exe [-fFirstname [-mMiddlename] -lLastname -iPatientid [-dBirthday] [-jBirthmonth] [-yBirthyear] [gGender]]
•
•
No spaces are allowed in the individual parameters.
The parameter sequence is irrelevant.
Example: “tscan.exe -fJohn -lSmith -iBT1000 -d07 -j02 -y1962 -g2”
•

•
-f (lowercase F): Firstname can be any alphanumerical string, Tekscan truncates it at 15 characters.
-m (lowercase M): Middlename can be any alphanumerical string, Tekscan truncates it at 15 chars (optional).
-l (lowercase L): Lastname can be any alphanumerical string, Tekscan truncates it at 20 chars.
-i (lowercase I): Patientid can be any alphanumerical string, Tekscan truncates it at 20 chars.
"Patientid" is the “key” link between the starter program and Tekscan software. This Patientid can be any sequence of
characters or letters the user desires. The semantics of the Patientid is irrelevant. Tekscan only makes a case-insensitive
alphanumeric search in the software database. If the same string is found, the patient is treated as a current patient in
the software, and his/her record is opened. If the patient is not found, the patient is treated as a new patient. If the same
Patientid is found, but there is a discrepancy between first, last or middle names, then a warning message is displayed.
If you already have several patients within your Tekscan Patient Database, and wish to create a link from an external
application, the recommended procedure is to change the Patient information (Patientid, First Name, Last Name, etc.)
within the Tekscan Patient Database to match that of the external application. This ensures duplicate records are not
created if there is a mismatch between the two sets of information.
