Shade Determination — Tooth Shade, Shade of the Prepared
Tooth
Optimum integration in the oral cavity of the patient is the prequisite 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. In order to achieve the
desired esthetics, the shade of the prepared tooth must first be determined.
