Staining and veneering
There are three different techniques for staining, characterizing, and veneering
IPS Empress CAD:
1. Internal characterization
Tetric ® Color are light-curing composite stains for individualized characterizations.
They are ideally suitable for internal characterizations (cementation side) of
IPS Empress CAD restorations (e.g. veneers). After etching (60 seconds with
IPS Ceramic Etching Gel) and silanating (Monobond-S), the stains are applied. After
that, the stains are polymerized with a curing light of the bluephase family. No further
ceramic firing cycles should be conducted after the "internal characterization" with
Tetric Color.
2. External characterization*
IPS Empress ® Universal Shade / Stains are ceramic stains for individualized
characterizations. Among other things, they are ideal for external staining and
characterization of IPS Empress CAD restorations.
The dentin stains are available in 9 A-D and 15 Chromascop shades. For individualized
characterizations, 14 intensive stains are available. To reproduce the incisal
area, there are 2 Incisal Shades, which provide the incisal third with
optical translucency and an in-depth effect. For the final glaze firing
of the IPS Empress restorations, a smooth and fine-grained glazing paste is available.
3. Cut-back technique*
IPS Empress ® Esthetic Veneer ceramic material are leucite-reinforced layering
materials for the cut-back technique. In this technique, fully anatomical IPS Empress
CAD restorations (veneers and anterior crowns) are reduced in the incisal third to a
dentin-mamelon structure and subsequently completed using materials in paste and
powder form in order to design a true-to-nature and aesthetic incisal third.
The IPS Empress Veneer Kit comprises a selection of the most popular wash pastes and
layering materials required for the cut-back technique of IPS Empress restorations
(Esthetic and CAD). With the wash pastes, an excellent and homogeneous bond with
the reduced restoration is achieved. The layering materials feature incisal-like
fluorescence and true-to-nature opalescence. Additional wash pastes and layering
materials available as Refills are indicated on the material shade guide supplied with
the Kit.
