Tooth – Shade determination

Tooth – Shade determination

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 tooth stump (natural stump, devitalized stump, core build-up, abutment)
Shade of the cementation material
Shade of the restorative material (framework shade, translucency/opacity, brightness, veneer,

characterization)

Shade determination of the natural tooth

– Determine the tooth shade of the non-prepared tooth and/or the adjacent

teeth after tooth cleaning.

– In addition, determine the cervical shade if a crown preparation is planned,

for example.

– Determine the shade at daylight and in front of a neutral background.
– Avoid intensively coloured clothes and/or lipstick as these may

compromise the result.

– Use the A-D Shade Guide or Chromascop Shade Guide.
