Description
A very popular re positioning of the tabs in VALUE order: B1, A1, B2, D2, A2, C1, C2, D4, A3, D3, B3, A3.5, B4, C3, A4, C4.
The VITA classical A1 – D4 shade guide serves to accurately determine tooth shade.
The arrangement of the shades in the VITA classical family of shades is as follows:
- A1 – A4 (reddish-brownish)
- B1 – B4 (reddish-yellowish)
- C1 – C4 (grayish shades)
- D2 – D4 (reddish-grey)
Tips for shade-taking:
If possible, determine the shade under daylight conditions or standardized daylight lamps, and not under normal indoor lighting conditions.
The shade-taking environment should preferably be in muted colors. Patients should be asked to remove lipstick or any cosmetics which could have an influence on shade- taking. Clothing in pronounced colors should be covered with a grey overall.
Make your choice swiftly; always accept your first decision, since the eyes begin to tire after approx. 5 – 7 seconds.
Procedure:
Hold the shade guide at a suitable distance (at arm’s length) against the patient’s mouth.
Make your choice of shade without hesitation by comparing the shade samples of the shade groups A – D with the natural tooth.
Disinfect the shade guide after every shade
