Shade Determination – Tooth Shade, Shade of the Prepared

Tooth

Optimum integration in the oral cavity of the patient is the prerequisite for a true-to-nature all-ceramic

restoration. To achieve this, the following guidelines and notes must be observed by both the dentist

and the laboratory.

The overall esthetic result of an all-ceramic restoration is influenced by the following factors:

• Shade of the preparation (natural preparation, core build-up, abutment, implant)

• Shade of the restoration (framework shade, veneer, characterization)

• Shade of the cementation material

The optical effect of the preparation shade must not be underestimated during the fabrication of highly

esthetic restorations. For that reason, the shade of the preparation should be determined together with

the desired tooth shade in order to select the suitable block. Especially with severely discoloured

preparations or non-tooth-shaded build-ups, this is of utmost importance. Only if the dentist determines

the shade of the preparation and its subsequent transmission to the laboratory may the desired esthetics

be achieved in a targeted fashion.
