Step 1

Unpack Easyshade and install the calibration port (the calibration block and retainer)
Set the handpiece in the retainer
Plug Easyshade into the power source and press the power switch on the front of the unit
Allow the unit to warm up

Step 2

Remove an Easyshade infection control shield from the pack. Each shield needs to be peeled from the harder outer layer protecting it. Stretch it to cover the tip as displayed. Do not be afraid to over-stretch it. It needs to be treated similarly to cling film.
Inspect the probe tip to ensure that the optical face of the probe is evenly covered by the protective layer and that it has no creases.
Please be aware that each time a new sleeve is put on the unit, it will need to be re-calibrated.
We do not recommend keeping the unit on for any length of time. Once the shade has been determined, we suggest that the unit is switched off to assist longevity of parts.

Step 3

Once the unit has warmed up, the screen will read 'Apply shield and calibrate'
Calibration must take place each time the machine is switched on or each time a new protective sleeve is applied.
To calibrate - without pressing any buttons, place the tip of the handpiece firmly into the calibration port.
You will see a light come on from the handpiece.
Hold the probe tip steadily in place until Easyshade sounds a beep to indicate the calibration is complete.

Probe placement

Describes correct probe placement in images

A: Correct placement (probe tip perpendicular and flush on tooth surface)

B: Incorrect placement (probe tip not flush on surface of tooth)

C: Incorrect incisal placement (probe tip must be a minimum of 2mm from incisal edge)

D: Incorrect cervical placement (probe tip too close to gingival tissue. Maintain 2mm minimum separation from tissue margin)

Step 4

If you wish to check the unit against the 3D shade guide, pick a shade tab, ie 2M1 from your 3D shade guide.
On the touch screen press with your finger the arrowed area on the screen until it states 'Shade Tab'. Underneath, it will read 'Ready to test Shade Tab'.
Place the tip squarely against the middle of the tooth, as flat as possible, and press any one of the finger buttons on the hand piece.
The unit will light for about 2 seconds and the shade will show in relation to the shade tab. If it is not correct, check the sleeve again and re-calibrate by turning the unit off and then on again, letting it warm up, and follow the calibration process as previously indicated in Step 3.

Step 5

To take a simple shade of a tooth, press the arrowed box on the screen until it reads ‘Tooth single’
Underneath it will read ‘Ready to measure tooth’

Step 6

Place the tip squarely against the middle of tooth, as flat as possible and press any one of the finger buttons on the hand piece.
The unit will light for about 2 seconds and the shade will be indicated as shown. If the classical shade is not shown and you wish to see it, please consult the instruction manual as this is a setting within the menu settings.
Easyshade will interpolate shades, please see interpolation sheet to understand this. It's really very easily understood.

Step 7

To provide a more in-depth analysis of tooth shade, you can measure three areas of a tooth.
To measure three areas of a tooth, press the arrowed area until it reads 'Tooth areas'.
Place the tip close to the cervical area and press any button on the hand piece.
Repeat the process for the middle and incisal areas.

Interpolated Vita 3D-Master shades

The 29 Vita 3D-Master shades are shown in bold in the following tables. Also shown are 52 interpolated shades that can only be matched by using Vita 3D-Master porcelains which are mixed appropriately and equally.

Easyshade measures teeth and restorations to the nearest 3D-Master interpolated shade. With the addition of the Vita Classical 16 shades, which cannot be interpolated, a total of 97 shades may be selected by Easyshade and displayed in seconds.

M L and R Shades table

Interpolated shades explained

The first number of a shade (2M1) indicates the 'Value group' (brightness of the shade). The five groups are displayed from the lightest to the darkest. In this case (2M1) value group 2.

The letter on the shade guide indicates the hue (colour). The 'L' (eg 2L1.5) stands for Left and represents the more yellow hue, the 'M' (eg 2M1) stands for Middle and represents the middle shade between the Yellow and Red hues, and the 'R' (eg 2R2.5) stands for Right, which represents the Red hue.

The last number (2M1) on the tab is the 'Chroma' level (or colour saturation/intensity)

All these parameters are interchangeable within the three dimensions of colour and do not affect or influence the others. They enable one to arrive at a Vita 3D-Master interpolated shade. Refer to the interpolated 3D-Master shade chart (above) and cross-reference the target shade. To achieve an interpolated shade, it is necessary to mix together either 2 powders (50% each) of 4 powders (25% each).

Example 1: To arrive at the Shade 1.5M1.5 (this shade is half way between 1M1 and 2M1), mix 50% of 1M1 powder with 50% of 2M1.
Example 2 as shown in the picture: If Shade 1.5M1.5 is required, mix 25% of 1M1, 25% of 2M1, 25% of 1M2 and 25% of 2M2.

Vita 3D-Master shaded porcelains, including Omega 900, VMK95, VM7 and VM9 are the only porcelains made specifically to replicate the interpolated 3D-Master shades 'out of the bottle'. Vita 3D-Master shades are systematically arranged and replicate shades even when the restoration is varied in thickness. Shade interpolation is not a feature of Vita Classical shades.

Verifying shades

Press the arrowed area until it reads 'Restorations'
Select the shade originally prescribed to the laboratory. This could be an interpolated shade (please see interpolation)
Once shade is selected, wait until the screen reads 'Ready to verify shade'.
Take shade of the restoration using the hand piece as previously shown. The unit will indicate how accurate the restoration is to the shade you prescribed.

New Extended mode - Simply keep touching the display

By continually touching or tapping the screen display more data screens appear (4 in total). The 'translucency' screen compares a Vita shade guide tab translucence to the natural tooth in the middle third area.
It may also be beneficial in prescribing 'All-Ceramic' over 'VMK' restorations.
Touch once more (5th time) returning display to original screen.
See instruction manual to fully understand these workings.
