IPS e.max Shade Determination
Optimum integration in the oral cavity of the patient is the prerequisite for a true-to-nature all-ceramic restoration. Differences in the shade of the restoration and the natural tooth structure adversely affect the appearance of the teeth in particular.
The following factors influence the overall lifelike, esthetic result of an all-ceramic restoration
- shade of the preparation,
- shade, translucency and thickness of the restoration
- indication and material
Shade determination of the natural tooth
After tooth cleaning, the tooth shade of the non-prepared tooth and/or the adjacent teeth is determined with the help of a shade guide, also taking individual characteristics into consideration.
Preparation shade is decisive
During the fabrication of highly esthetic restorations, the influence of the preparation shade on the final result is a decisive aspect. This is especially important when preparations are severely discoloured. Only if the dentist correctly determines the shade of the preparation and effectively transmits it to the laboratory can the desired esthetics be achieved in a targeted fashion.
Die shade selection
In order to facilitate the reproduction of the desired tooth shade, the shade of the preparation is determined with the help of the IPS Natural Die Material shade guide. This enables the technician to fabricate a model die similar to the preparation of the patient, on the basis of which the correct shade and brightness values of the all-ceramic restoration may be selected.
