The IPS Empress all ceramic system is comprised of two unique materials. The shading technique materials are made of leucite reinforced glass. The new layering material (Empress2) is a combination of a lithium disilicate framework material and fluorapitite ceramic used in the layering phase of fabrication. This new material is indicated for three unit bridges with the 2nd premolar as the distal abutment and for anterior or posterior crowns. The original Empress shading technique material is indicated for anterior crowns, inlays, onlays and veneers. The new IPS Empress2 material can be either adhesive cemented using resin cement (Variolink 11) or conventional cemented with a low expanding conventional cement (e.g. ProTec CEM).
