Practical procedure for restoration with IPS e.max | 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.
