1.4 Applying an infection control shield.
It is important to properly clean and disinfect the instrument between patient
uses and to use a new Easyshade infection control shield for each patient
to prevent patient cross-contamination.
The infection control shield also protects the fiber optics in the instrument
from damage.
1. Insert the tip of the hand piece into the shield
2. Remove paper backing from the shield
3. Pull shield carefully over the hook
4. Secure shield on the hook
Verify that the infection control shield is stretched uniformly
and flat over the face of the probe tip, and is not torn
during application (fig. 3+4).
Then calibrate the instrument as described in section 1.6.
The infection control shield should remain in place for all
measurements with the same patient.
These non-sterile covers are for single patient use only and should
be properly disposed of.
Note: An infection control shield that has come into contact
with a patient must not contact the calibration block assembly.
If contact occurs, follow the instructions for cleaning and
disinfection of the calibration block assembly in section 11.

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).
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.
Incorrect placement (fig. 15):
Probe tip not flush on the tooth surface.
Correct measurement of a tooth

16
VI A Easyshade®Advance 4.0
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.

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. evitalized, 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. evitalized, 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.
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 proce-
dures. To this purpose, the Bleached Index measured after treatment should be
subtracted from the Bleached Index before treatment. The difference corres-
ponds to the number of SGUs (Shade Guide Units) of change achieved by the
treatment according to the American ental Association recommendation.

4.4 ooth 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.
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.
After successful measurement of all areas, the VITA classical A1– 4
and VITA SYSTEM 3 -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.
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– 4 or VITA SYSTEM 3 -MASTER shade.
The number of averaged measurements is displayed.

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 3 -MASTER and the 16 VITA classical A1– 4 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.
