37% phosphoric acid in a liquid delivery form.

Indications:
– Enamel etching and dentin conditioning for sealants, composite restorations, and for the adhesive cementation of restorations.

Advantages:
– Micro-interlocking of Heliobond bonding agent with the etched enamel
– The material flows well into the fissures due to the low viscosity
– Reliable retention of the sealant, composite, and the seated restoration

IPS Empress ceramic material has been known and established for processing in the laboratory for 20 years. Since the introduction of IPS Empress CAD, esthetic restorations may also be fabricated in the dental office by means of CAD/CAM. Moreover, the IPS Empress family is supplemented by a composite for direct restorative therapy: IPS Empress Direct (see under Composites).

IPS Empress CAD blocks are suitable for the fabrication of all-ceramic inlays, onlays, veneers, and crowns by means of CAD/CAM.

They are available in two levels of translucency (high translucency and low translucency) as well as a polychromatic IPS Empress CAD Multi Block.
IPS Empress CAD restorations are finally either only polished or stained and glazed, and adhesively cemented.

IPS Empress® CAD HT

The IPS Empress CAD HT blocks exhibit a higher translucency and lower brightness value than the LT blocks. They are ideally suitable for fabricating inlays and onlays because of their exceptional chameleon effect. The high translucency of the material and its lifelike fluorescence allow the restoration to blend in seamlessly with the surrounding dentition.

 IPS Empress® CAD LT

The IPS Empress CAD LT blocks are characterized by their high level of brightness and true-to-nature chroma. Therefore, they are particularly suitable for fabricating larger restorations.
The specially adjusted brightness of the material prevents "greying" of full and partial restorations. The blocks demonstrate a naturallooking fluorescence, which matches the different indications.
Therefore, the restorations seamlessly blend into the remaining dentition under different light conditions.

IPS Empress® CAD Multi

The polychromatic IPS Empress CAD Multi blocks offer a smooth colour transition between the dentin and incisal areas. They
produce highly esthetic and natural-looking results, even without characterization. IPS Empress CAD Multi blocks feature a high level of chroma and lifelike opacity in the cervical areas and the desired level of translucency in the incisal region.
