3 Measuring a toothThe instrument may be used to measure a single area on a tooth("Tooth single") or to measure the cervical, middle and incisal areas("Tooth areas") as described in section 4.

Procedure to perform accurate measurements with VITA EasyshadeAdvance (for purposes of illustration, the probe tip is shown withoutan anti-infection cover):

Have the patient sit on a chair and lean back his head.The probe tip must be placed on an area of the enamel surfacethat has underlying dentine (middle to cervical area).

The probe tip must be placed perpendicular and flushto the tooth surface as shown in the adjacent figure (fig. 15).

While holding the probe tip steady against the dentine centerof the tooth, press the Measurement button and hold the probe tipagainst the tooth until two rapid "beeps" can be heard to indicatecompletion of the measurement.

VITA Easyshade Advance will display the results of the measurement.

Incorrect placement (fig. 16):Probe tip not flush on the tooth surface.

Incorrect placement – incisal (fig. 17):Probe tip must be a minimum of 2 mmfrom the incisal edge.

Incorrect placement – cervical (fig. 18):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 priorto the instrument sounding a "beep", an error messageor an erroneous measurement will be displayedand the measurement will need to be repeated.

Note: Prior to measuring a tooth, an infection control shieldmust be applied to the VITA Easyshade Advance probe tipand the instrument must be calibrated. It is recommendedto remove any stains from the surface of a tooth priorto measurement. It may be required to wipe the toothwith gauze to prevent the tip from sliding. The probe tipmust be placed entirely on the natural tooth. Any contactwith existing restorations must be avoided. Underlyingrestorations may adversely affect the measurement result.

4.1.1 VITABLOCS modeThe VITABLOCS mode informs you which VITA block should be usedfor accurate reproduction of the measured tooth.Highlight the Tooth/BLOCS icon and press the Enter button to confirm.

The suitable VITABLOCS in the VITA classical A1–D4 or VITA SYSTEM3D-MASTER shade systems are displayed. If a suitable block is notavailable in the VITA classical A1–D4 shade system (--- is displayed),use the block indicated in the VITA 3D-MASTER SYSTEM.

Note:To determine the correct block shade, a distinction is made between4 initial situations. Generally, measurements should not be carried outon prepared teeth (stumps) since they are too small and normallyalso darker than natural teeth.

1. Vital, non-discoloredEasyshade is used to determine the base shade on the tooth and therestoration can be prepared without any additional characterization.

2. Vital, discoloredEasyshade is used to determine the base shade on the tooth;the shade of the prepared restoration, however, needs to becharacterized before the restoration is seated (Akzent, Shading Paste).

3. Devitalized, non-discoloredEasyshade is used to determine the base shade on the tooth and therestoration can be prepared without any additional characterization.

4. Devitalized, discoloredThe tooth should not be measured with Easyshade; an adjacent toothwith 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.

Modes of operation

In the detail screen, the shade codes behind the arrow icon provideinformation about the nearest tooth shades. A detailed descriptionof the screen can be found in section 7.

Note: Compare the shade measured with a shade tab if possiblein daylight, under standardized daylight lamps or at 5500 - 6500 Kand not under normal indoor lighting!

4.3 Measuring on ceramic restorationsVITA Easyshade Advance enables dental professionals to verifythat a ceramic restoration's shade is an acceptable match tothe prescribed shade. The 29 shades and the 52 interpolated shadesof VITA SYSTEM 3D-MASTER and the 16 VITA classical A1–D4 shadescan be verified.Moreover, it is possible to determine the extent of deviationof a ceramic restoration from a standard defined by the user.Additionally, the instrument enables the determinationof the shade of a ceramic restoration.

4.3.1 Comparison of the shade with the VITA standardTo verify a restoration, highlight and select the Restoration iconon the Measurement menu and press the Enter button.The target shade is selected before measuring the restoration.After selecting the target shade, measure the middle thirdof the restoration. 1 to 3 asterisks, as shown in the following figures,indicate the degree to which the restoration matches the target shade.

To select a target shade, select the first digit or letter usingthe navigation buttons and the Enter button. Then only the digitsand letters can be selected, which may produce a correspondingVITA SYSTEM 3D-MASTER or VITA classical A1–D4 shade.

B selected first, then only 1, 2, 3 and 4 can be selected (fig. 33).

To select interpolated shades, go to the Extended Color mode (fig. 34).Navigation in the menu remains unchanged.

35 4.3.2 Comparison of the shade with the user standardA user standard is defined by measuring a restoration with any target shadeand then saved by selecting the Disk icon. After saving the standard,any deviations are set to zero, three *** (asterisks) are displayedsince the measurement is set as a reference value. Below the three ***(asterisks) you can see which VITA shades correspond to the measurement.As long as no target shade is selected, all other measurements in this modeare compared with the reference measurement determined by the userand displayed accordingly. The reference measurement defined bythe user can be chosen as a target shade after ticking the check mark.When a new standard is saved, the current reference measurementwill be overwritten.

4.3.3 Determining the shade of a ceramic restorationThe measurement is performed analogously to saving a user standard.The shade is displayed in VITA classical A1–D4 or VITA SYSTEM3-MASTER and helps to choose the VITA ceramic that ensuresperfect reproduction of the shade.

Note: To verify a restoration, only the base shade of therestoration is measured in the middle third of the restoration.The ceramic material must have a minimum thickness of 0.8 to1.5 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.

*** "Good" means that the base color of the restorationhas little or no color difference from the target shadeto which it has been verified.

** "Fair" means that the base color of the restorationmay have a noticeable but acceptable differencefrom the target shade to which it has been verified.However, this may not be acceptable for an anterior restoration.

* "Adjust" means that the base color of the restorationhas a noticeable difference from the target shadeto which it has been verified, and that the restorationshould be adjusted to be an acceptable shade match.

Press the Enter button to return to the "Verify restoration" screen.

L +/- The lightness of the restoration is above / below the lightnessof the target shade.

C +/- The chroma of the restoration is above (more intensive) / below (paler)than the chroma of the target shade.

5 Training modeTo learn how to use VITA Easyshade Advance, it is useful to practiceusing the instrument by measuring VITA Linearguide 3D-MASTER,VITA Toothguide 3D-MASTER or VITA classical A1–D4 shade tabs.

To measure a shade tab, highlight the Shade tab iconon the Settings menu.

Hold the probe tip steady on the middle of the shade taband exert slight pressure.Then press the Measurement switch.

The measurement result with the closest shade matchas determined by the instrument is displayed on the screen.

Use the Classical and 3D-MASTER icons to switchbetween the different shade systems.

If the probe tip is not held steady or is partially off the shade tab,faulty measurements will result. The instrument detects anddisplays major measurement errors (fig. 43).

For purposes of training, repeat the measurement untila correct result is displayed.

Note: The 29 VITA Linearguide or Toothguide 3D-MASTER shadesand the 16 VITA classical A1–D4 shades are displayed in the Training mode.Measuring other shade guides or interpolated VITA shade tabs willproduce different (possibly inaccurate) results. Due to the small differencein the color and the natural color variations of the shade tabs, even slightchanges in the measurement process may lead to the fact that a nearest"neighbor shade" is displayed for some shades.

CIEL*a*b*

An instrument for color measurement that measures the spectral distributionof light and converts it into color values (tristimulus value) or an internationallyaccepted numerical form.

Refers to the 29 shade sample teeth including 3 Bleached Shade Guideand the 52 VITA SYSTEM 3D-MASTER interpolated shades.

Refers to the 16 original VITA classical A1–D4 shades found on the VITA classicalA1–D4 shade guide, which was originally called the Lumin Vacuum shade guide.

The luminance of the color. It is the lightness or darkness of a color relativeto a series of grays ranging from white (L = 100) to black (L = 0).

The saturation (intensity) of a color. It is the difference between the colorand a gray having the same brightness, measured as the distance from theneutral axis. It is sometimes referred to as the purity of the color.

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 isrepresented 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°).

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.

A three-coordinate representation of color (tristimulus) in color space, definedby the International Commission on Illumination (Commission Internationaled'Eclairage). For additional information on color theory visit VITA's website atwww.vita-zahnfabrik.com
