Synergy in Dentistry - Vol.3, No. 1, 2005

The drive for all-ceramic or metal-free dentistry has had its ups and downs over the past decade. However, computer-aided design/computer-aided manufacturing (CAD/ CAM) materials have been introduced into the marketplace for the fabrication of single-unit restorations and 3and 4-unit bridges. These materials hold promise for predictably satisfying the need for esthetic and strong restorations for such indications. Proper case selection for such all-ceramic restorations—as well as adhering to standard clinical protocol for preparation design, impression-making, and cementation—is essential. This article presents a case in which an anterior 3-unit, allceramic CAD/CAM bridge (Lava Crowns and Bridges System) was used to replace a previously placed porcelain-fused-to-metal bridge.
