Versatility and aesthetics of the IPS Empress all-ceramic system.

With the reestablishment of function no longer a clinical issue, the aesthetic challenge takes precedence, with patients expecting natural-looking results. Since the late 1980s, a leucite-reinforced pressed-glass ceramic (IPS Empress, Ivoclar Williams, Amherst, NY) has been utilized in the anterior region for full crowns and veneers and in the posterior region for crowns, inlays and onlays. This article presents results achieved with the IPS Empress all-ceramic system, which features a unique combination of strength and natural light transmission qualities that resemble the characteristics of natural teeth.
