Uses
Indications
IPS Empress CAD blocks can be used for the following adhesively cemented restorations. Depending on
the type and size of the restoration, the respective HT (High Translucency), LT (Low Translucency), or
Multi Block is recommended. IPS Empress CAD restorations may be cemented either polished,
stained/glazed, or veneered.
For further processing of IPS Empress CAD restorations, users have the following options:
– Aesthetic characterization and glazing of fully anatomical restorations using IPS Empress Universal
Shades, Stains, and Glaze pastes.
– Aesthetic veneering in the incisal third of reduced restorations (veneers and anterior crowns) using
IPS Empress Esthetic Veneer materials
Contraindications
– Bridge reconstructions
– Conventional cementation
– Very deep, subgingival preparations
– Patients with severely reduced residual dentition
– Bruxism
– Fully (circularly) veneered anterior and posterior crowns using IPS Empress Esthetic Veneer
