How do you determine the tooth shade with VITAPAN 3D-MASTER?

The logical configuration of the shades makes working with VITAPAN 3D-MASTER very easy. The shade selection is a logical progression of three simplified choices - the desired shade is found very quickly:

In the first step of the shade taking procedure the value (lightness) is determined. Select the value level from the five value groups (levels 1 - 5) that is closest to the value of the tooth to be compared. Pull out the medium shade sample (M) from the selected value group.

In the second step the chroma (levels 1 2,3) is determined. Select the color sample of the selected M group that is closest to the tooth to be compared.

In the third step the hue (L, M, R) is determined. Check whether the natural tooth displays a "more yellowish" (L) or "more reddish" {R) shade than the color sample of the M-group that has been selected in the second step. Now the best matching shade sample is determined and the information is recorded in the color communication form.

	Value (lightness) level In the first step the value or lightness is determined.
	Chroma In the second step the chroma or color saturation is determined.
	Hue In the third step the hue is verified.

Tips for shade taking.

This makes shade taking even easier and more secure:

• Hold shade guide to the patient's mouth at arm's length.
• When taking a shade it is important not to use a direct source of light but to work under diffuse lighting. Ideal are natural daylight or suitable daylight lamps.
• Make a swift selection; always accept your first decision.
• When determining the shade, ask your patient not to wear bright colors or lipstick.
