Description

IPS Empress CAD

IPS Empress CAD is associated with many years of successful clinical performance. It closely reproduces the natural tooth structure due to its distinct chameleon effect and lifelike fluorescence. IPS Empress CAD restorations demonstrate excellent light-optical properties and an outstanding mean biaxial flexural strength of 185 MPa1.

IPS Empress CAD is known for exceptional esthetics and can be easily polished to a high gloss: grind – polish – done.

Restorations made of IPS Empress CAD can be stained or glazed. The universal staining and glazing assortment IPS e.max Crystall./Shades/Stains and Glaze is suitable for this purpose.

IPS Empress CAD Multi
The multi-coloured IPS Empress CAD Multi BLOCKS produce restorations showing a natural-looking transition of the shade and fluorescence between the dentin and incisal areas. As a result, maximum esthetics and a vital appearance are achieved without having to characterize the restorations.

IPS Empress CAD HT / LT
IPS Empress CAD BLOCKS are available in two translucency levels (HT and LT). They are supplied in A-D shades as well as in Chromascop shade groups. Furthermore, IPS Empress CAD LT BLOCKS in four modern Bleach shades (BL1-BL4) complement this range of materials.

Indications

Crowns
Inlays, onlays
Veneers

Benefits

Highly esthetic restorations, efficiently created
Clinically proven ceramic material with a flexural strength of 185 MPa1

IPS Empress CAD BLOCKS are made of a leucite-reinforced glassceramic which consists of a glass and a crystal phase. Leucite crystals of few microns evenly grow in a multi-stage process directly from the amorphous glass phase. During the fabrication of the BLOCKS, the semi-finished product in powder form is pressed to BLOCKS in a fully automated procedure, which enables a maximum of homogeneity. Given the difference in the coefficients of thermal expansion (CTE) between the glass phase and the crystal phase (leucite), cooling after sintering produces compressive stress in the glass phase. This mechanism results in an increase in strength and enables IPS Empress CAD to achieve a flexural strength of 160 MPa.
