Determining the basic tooth shade
Differences between natural tooth shades are primarily due to differences in lightness levels, and patients can be extremely aware of these. Consequently, determining the basic shade of a tooth is the key prerequisite for patient acceptance. The basic shade is found in the dentine center (central to gingival area). The VITA Toothguide 3D-MASTER, the VITA Linearguide 3D-Master and VITA Easyshade enable you to quickly, easily and reliably determine this key shade component.

Determining shade effects
Each natural tooth is a unique miracle of nature, so once
the basic shade has been determined, it is important to establish the detail of
the tooth, e.g. translucent areas or anomalies, in order to make the
reproduction as similar to the natural tooth as possible. We recommend taking a
digital photo in order to analyze the shade effects and details.

Tips on shade taking: - Shade-taking should be carried out prior to preparation as the ensuing dehydration makes tooth shades unnaturally white.
- Tooth shades should be determined in natural light if possible, or using a standard daylight lamp and not an operating lamp.
- Make your selection quickly and always go with your initial decision, as eyes tire after 5 to 7 seconds.
- There should be no bright colors in the shade-taking environment. That means the patient should not wear lipstick, tinted glasses or brightly colored clothing (this can be covered with a gray or cream colored cloth).
