VITA Easyshade® Advance 4.0 Correct measurement of a tooth
3 Correct measurement of a tooth
The instrument may be used to measure only the central area on a tooth
("Basic shade measurement") or to measure the cervical, central and incisal
areas ("Measurement of tooth areas") as described in section 4.
Procedure to perform accurate measurements with VITA Easyshade
Advance 4.0 (for purposes of illustration, the probe tip is shown without
an anti-infection cover):
Have the patient sit on a chair and lean back his head.
Observe the color gradient of the tooth to be measured precisely
beforehand and locate the dentine centre.
The probe tip must be placed on the area of the enamel surface
that has underlying dentine (central to cervical area).
14
The probe tip must be placed perpendicular and flush
to the tooth surface as shown in the adjacent figure (fig. 14).
While holding the probe tip steady against the dentine center
of the tooth, press the Measurement button and hold the probe tip
against the tooth until two rapid "beeps" can be heard to indicate
completion of the measurement.
VITA Easyshade Advance 4.0 will display the results of the measurement.
15
Incorrect placement (fig. 15):
Probe tip not flush on the tooth surface.
13
VITA Easyshade® Advance 4.0 Correct measurement of a tooth
16
17
Incorrect placement – incisal (fig. 16):
Probe tip must be a minimum of 2 mm
from the incisal edge.
Incorrect placement – cervical (fig. 17):
Probe tip too close to gingival tissue.
Maintain a minimum distance of 2 mm to the tissue margin.
If the probe tip is moved off of the tooth prior
to the instrument sounding a "beep", an error message
or an erroneous measurement will be displayed
and the measurement will need to be repeated.
Note: Prior to measuring a tooth, an infection control shield
must be applied to the VITA Easyshade Advance 4.0 probe tip
and the instrument calibrated. It is recommended to remove
any stains from the surface of a tooth prior to measurement.
It may be required to wipe the tooth with gauze to prevent
the tip from sliding. The probe tip must be placed entirely on
the natural tooth. Any contact with existing restorations must
be avoided. Underlying restorations may adversely affect
the measurement result.

the VITA SYSTEM 3D-MASTER.
17
VITA Easyshade® Advance 4.0 Modes of operation
Note:
To determine the correct block shade, a distinction is made between
4 initial situations. Generally, measurements should not be carried out
on prepared teeth (stumps) since they are too small and normally
also darker than the unprepared teeth.
1. Vital, non-discolored
Easyshade is used to determine the base shade on the unprepared tooth and
the restoration can be prepared without any additional characterization.
2. Vital, discolored
Easyshade is used to determine the base shade on the unprepared tooth;
the shade of the restoration, however, must be characterized before being
seated (Akzent, Shading Paste).
3. Devitalized, non-discolored
Easyshade is used to determine the base shade on the unprepared tooth and
the restoration can be prepared without any additional characterization.
4. Devitalized, discolored
The tooth should not be measured with Easyshade. An adjacent tooth
with the same shade should be selected to determine the block shade.
A devitalized tooth should be bleached internally prior to treatment
(attempt to reproduce the shade of a non-discolored, devitalized tooth).
The prepared tooth should be characterized as described under 2.
25
4.2.3 Display of the bleached shade
To display the bleached shade, please select the sun icon in the lower part of
the display.
When selecting this display mode, the bleached index is shown for the
measured shade according to the VITA Bleached Guide (Art. no. B361).
The Bleached Index enables the simple verification of tooth bleaching procedures. To this purpose, the Bleached Index measured after treatment should be
subtracted from the Bleached Index before treatment. The difference corresponds to the number of SGUs (Shade Guide Units) of change achieved by the
treatment according to the American Dental Association recommendation.

4.3 Averaged measurement on the natural tooth
With the averaged measurement up to 30 measurements can be made on a
natural tooth. The average of the measurement results is displayed as a VITA
classical A1–D4 or VITA SYSTEM 3D-MASTER shade.
The number of averaged measurements is displayed.
4.4 Tooth area measurement on the natural tooth
To measure the cervical, middle and incisal shades of a tooth, highlight
and select the Tooth area measurement icon on the Measurement menu.
Measurement sequence: cervical, middle and incisal.
29
To begin (empty circle), place the probe on the cervical area of the tooth and
press the measurement switch. Two rapid "beeps" will indicate a successful
measurement and "OK" will be displayed.
Proceed with the measurements of the middle and incisal areas.
30
After successful measurement of all areas, the VITA classical A1–D4
and VITA SYSTEM 3D-MASTER shade results will be displayed.
If an error occurs during measurement, a long "beep" will sound
and "X" will be displayed in the measured tooth area (not shown).
Repeat the measurement of the area until a successful measurement
result is obtained.
19
VITA Easyshade® Advance 4.0 Modes of operation
31
To receive extended color information, highlight and select one of
the displayed shade results.
32
Please note: The measurement data of the VITA Easyshade Advance 4.0
are dependent on the measurement mode, and only valid for natural teeth.
The measurements of shade samples is possible only in the training mode.
Measurements made on dental restorations should always be carried out
in the restoration mode.
4.5 Measuring on ceramic restorations
VITA Easyshade Advance 4.0 enables dental professionals to verify
that a ceramic restoration's shade is an acceptable match to a prescribed
shade (fig. 33). Here both the 29 shades, the 52 mixed shades of both the
VITA SYSTEM 3D-MASTER and the 16 VITA classical A1–D4 shades
can be verified.
Moreover, you can also define your own shade standard (User standard,
section 4.4.2) and compare the ceramic restoraton with this. It is also possible
to determine the approximate shade value of the restoration.
20

4.5.1 Comparison of the shade of the VITA standard
To verify a restoration, select the icon for verifying the shade of
a restoration (fig. 33) and press the Enter button.
The target shade is selected before measuring the restoration
To select a target shade, select the first digit or letter using
the navigation buttons and the Enter button. Then only the digits
and letters can be selected, which may produce a corresponding
VITA SYSTEM 3D-MASTER or VITA classical A1–D4 shade.
34
35
Example: If a B is selected first, only the digits 1, 2, 3 and 4 will be
subsequently available as selection options (fig. 34).
To select mixed shades, go to the Extended Color mode (fig. 35).
Navigation in the menu remains unchanged.
After selecting the target shade, measure the middle third
of the restoration. 1 to 3 asterisks (*), as shown in the following figures,
indicate the degree to which the restoration matches the target shade.
21
VITA Easyshade® Advance 4.0 Modes of operation
36
37
38
*** Three asterisks mean “good”. That means that the base color
of the restoration has little to no color difference from the target
shade with which it has been compared.
** Two asterisks mean “fair”. That means that the base color of the
restoration may have a noticeable but still acceptable difference
from the target shade with which it has been compared.
However, this may not be sufficient for an anterior restoration.
*
One asterisk means “adjust”. That means that the base color of the
restoration has a noticeable difference from the target shade with
which it has been compared. The restoration should be adjusted
in order to obtain an acceptable shade match.
You will find a detailed description of the display in section 7.
Press the Enter button to return to the measurement menu.

4.5.2 Comparison of the shade of the restoration with a user standard
Select the Restoration mode (fig. 39). Now enter any tooth shade or highlight
the user standard icon (fig. 39). Measure the target shade of a ceramic
restoration with which the actual restoration is to be compared. Highlight the
disk icon (fig. 40) and press the Enter key. The shade measurement is now
saved, and will be displayed as the approximate VITA classical A1–D4 shade
and the VITA SYSTEM 3D-MASTER shade. All shade deviations are reset to
zero after saving, and three *** asterisks are displayed. This shade is now
defined as the user standard.
All subsequent shade measurements in this mode (without saving) will be
compared with the user standard and the match displayed with * to ***
asterisks, and the deviations in the LCh value displayed. The user standard
can be recalled at any time as a target shade by activating the user standard
icon (fig. 41). In order to define a new user standard, repeat the procedure
described at the beginning. The previous user standard will then be overwritten.
4.5.3 Determining the shade of a ceramic restoration
In order to determine the shade of the ceramic restoration, define this as a
user standard. The shade is displayed as the VITA classical A1–D4 and the
3D-MASTER shade and helps to choose the VITA ceramic that ensures perfect
reproduction of the shade.
Attention! The tooth shade measurement will be displayed only after saving.
Note: To verify a restoration, only the base shade of the
restoration is measured in the middle third of the restoration.
The ceramic material must have a minimum thickness of 0.8 to
1.5 mm to ensure accuracy of the measurement.
Very translucent all-ceramic restorations, such as veneers,
will require the application of a tooth-colored material,
such as VITA Simulate, to obtain accurate measurement results.

5 Training mode
To learn how to use the VITA Easyshade Advance 4.0, it is useful to practice
using the instrument by measuring the VITA Linearguide 3D-MASTER,
VITA Toothguide 3D-MASTER or VITA classical A1–D4 shade tabs.
To measure a shade tab, highlight the Shade tab icon
on the Settings menu.
43
Position the probe tip steady on the middle of the shade tab
and exert slight pressure.
Then press the Measurement switch.
The closest tooth shade match will be displayed.
44
45
Highlight the 3D/A1-D4 icon. You can now switch between
the two shade systems using the Select key.
If the probe tip is not held steady or is partially off the shade tab,
faulty measurements will result. The instrument detects and
displays major measurement errors (fig. 45).
For purposes of training, repeat the measurement until
a correct result is displayed.
Note: The 29 VITA Linearguide or Toothguide 3D-MASTER shades
and the 16 VITA classical A1–D4 shades are displayed in the Training mode.
Measuring other shade guides or VITA mixed shade tabs will produce
different (possibly inaccurate) results. Due to the small difference in the
color and the natural color variations of the shade tabs, even slight
changes in the measurement process may lead to the fact that a nearest
"neighbor shade" is displayed for some shades.

12.3 Troubleshooting
Problem
Then ...
VITA Easyshade Advance 4.0 cannot
be turned on.
Charge the battery as described in section 1.3.
VITA Easyshade Advance 4.0 cannot
be calibrated or repeatedly
prompts to calibrate again.
Make sure that the probe tip is correctly placed into the calibration block
holder and held at an angle of 90° and is not lifted before hearing the "beep",
which indicates completion of calibration. Reposition the probe tip as needed.
Make sure that the IR ports of the base unit and the hand piece are not blocked
(see section 1.6.1).
Measurements cannot be made after
switching on the VITA Easyshade
Advance 4.0.
The VITA Easyshade Advance 4.0 first has to be calibrated after switching on
(see section 1.6.). Only then is a measurement possible in the desired measurement mode (see section 4).
A measurement is made and
VITA Easyshade Advance 4.0
displays "---" in place of a
VITA classical A1–D4 shade or
VITA SYSTEM 3D-MASTER shade.
Either the color is outside the known range of dental shades,
the probe tip was not correctly positioned or was lifted or moved
during the measurement. Measure again; be careful to use proper
placement technique.
Inaccurate shades are always
displayed when testing on shade tabs.
Make sure that Easyshade is in Shade Tab mode. Make sure that the
calibration block and the probe tip are clean; then re-calibrate the unit.
Use only approved VITA Easyshade Advance 4.0 anti-infection covers.
Repeat the measurement, assuring that the probe tip is touching
the surface at 90° in the middle of the shade tab and that the probe tip
is not moving during the measurement. Compare the serial number
to make sure that the correct calibration block for VITA Easyshade Advance 4.0
is installed. Make sure that only VITA Linearguide or Toothguide
3D-MASTER and VITA classical A1–D4 shade tabs are used.
A letter (S or W) is displayed
to the right of the Toolbar icon.
This indicates a temporary change to the instrument, due to environmental
factors, such as static discharge or disconnecting the battery.
Turn the unit off and on again; the letter will not be displayed.

12.6 Glossary
Spectrophotometer
An instrument for color measurement that measures the spectral distribution
of light and converts it into color values (tristimulus value) or an internationally
accepted numerical form.
VITA SYSTEM 3D-MASTER shades
Refers to the 29 shade sample teeth including 3 Bleached Shade Guide
and the 52 VITA SYSTEM 3D-MASTER mixed shades.
VITA classical A1–D4 shades
Refers to the 16 original VITA classical A1–D4 shades found on the VITA classical
A1–D4 shade guide, which was originally called the Lumin Vacuum shade guide.
Value
The luminance of the color. It is the lightness or darkness of a color relative
to a series of grays ranging from white (L = 100) to black (L = 0).
Chroma
The saturation (intensity) of a color. It is the difference between the color
and a gray having the same brightness, measured as the distance from the
neutral axis. It is sometimes referred to as the purity of the color.
Hue
What we commonly call color (red, yellow, green, blue or some other color).
It corresponds to the physical wavelength of light. In the L*C*h* system it is
represented as an angle ranging from 0° to 360°. Angles that range from 0° to 90°
are reds, oranges and yellows; 90° to 180° are yellows, yellow-greens and greens;
180° to 270° are greens, cyans (blue-greens) and blues; 270° to 360° are blues,
purples and magentas, returning again to red at 360° (the same as 0°).
Mixed shades
The mixture of two or more shades of porcelain to achieve an intermediate shade.
For example, 2M2 can be mixed with 2M3 to achieve the shade 2M2.5.
CIE L*a*b*
A three-coordinate representation of color (tristimulus) in color space, defined
by the International Commission on Illumination (Commission Internationale
d'Eclairage). For additional information on color theory visit VITA's website at
