Technique for realistic anterior crowns using the IPS Empress porcelain system.

In dentistry, the concept of realism can be applied to the creation of an artificial prosthesis that is not perfect, but real. If prosthesis are made to a flawless perfection, they will appear artificial. Ultimately, the clinician and ceramist should strive for realism. The IPS Empress System (Ivoclar Williams, Amherst, NY) is an all-ceramic restorative alternative utilizing a pressable leucite-reinforced glass ceramic for a variety of indications (e.g., crowns, inlays/onlays, veneers). The resulting tooth-colored and metal-free restorations combine strength and aesthetics approaching those of natural teeth. This article describes the technique and procedures required to achieve realistic anterior crowns with this all-ceramic system.
