VITAPAN 3D-MASTER Shade Guide
Vita-3D – Step 1 Determine the lightness level (value)
Hold shade guide to patient’s mouth
Start with darkest group moving right to left
Select Value group 1, 2, 3, 4, or 5
Vita-3D – Step 2 Select the chroma
From your selected Value group, remove the middle tab (M) and spread the samples out like a fan
Select one of the three shade samples to determine chroma
Vita-3D – Step 3
Determine the hue
Check whether the natural tooth is more yellowish or more reddish than the shade sample selected
Vita-3D – Step 4
For more precise shade, intermediate levels for hue, value, and chroma can be given 2.5M2 = value between 2M2 and 3m2 3M1.5 = chroma between 3M1 and
3M2 3M2 / 3L2.5 = hue between 3M2 and
3L2.5
