Staining and veneering
There are three different techniques for staining, characterizing, and veneering
IPS Empress CAD.
Internal characterization
IPS Empress ® Direct Color are light-curing composite stains for individual characteri-
zation. 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 Plus), the stains are applied.
Subsequently, the stains are polymerized with a curing light of the Bluephase family.
No further ceramic firing cycles must be conducted after the "internal
characterization" with IPS Empress Direct.
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 CAD
restorations, a smooth and fine-grained glazing paste is available.
Cut-back technique*
IPS Empress ® Esthetic Veneer ceramic materials are leucite-reinforced layering
materials for the cut-back technique. In this technique, full-contour 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 esthetic 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 fluores-
cence 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.
* Please refer to the Combination Tables for the available shades and materials.
