Shade determination
The correct tooth shade is the basis for a restoration with a life-like appearance. After tooth cleaning, the tooth shade
of the non-prepared tooth and/or the adjacent teeth is determined. Individual characteristics have to be taken into
consideration when determining the tooth shade. If a crown preparation is planned, for example, the cervical shade should
also be determined. In order to achieve the best possible true-to-nature results, shade determination should be carried out
at daylight. Furthermore, the patient should not wear clothes of intensive colours and/or lipstick. Basically, it has to be kept
in mind that the final shade of the restoration is the result of the following individual shades:
– Die shade
– Shade of the ingot
– Shade of the layering ceramic
– Shade of the cementation material
IPS Natural Die Material
In order to facilitate the reproduction of the tooth shade, the shade
of the prepared tooth can be determined with the help of the
IPS Natural Die Material shade guide. This facilitates the fabrication
of the all-ceramic restoration and the individual characteristics of the
preparation may also be taken into consideration. By deterimining the
shade of the prepared tooth, the shade and brightness value of the
restorations may be checked during the individual fabrication steps.
IPS Empress Esthetic Shade Guide
With the IPS Empress Esthetic shade guide, the shade of the ingot
to be used can already be determined in the dental practice. In
addition, the shade guide may be used to select the suitable pressed
ingot and layering materials in the laboratory. The shade tabs have
been fired and pressed from original materials under laboratory
conditions and, therefore, correspond with the final result.
