Abstract

Porcelain fused to metal restorations have been considered as the gold standard in prosthetic dentistry for a long time thanks to their mechanical properties. However, several drawbacks (light transmission blocked by the metal and the opaque porcelain, metal corrosion phenomenon, gingival tattoo and potential allergic reactions) have limited its use. Recently, all ceramic materials have been introduced in prosthetic dentistry for the fabrication of natural like crowns and fixed partial dentures using CAD/CAM techniques. Zirconia seems to be of great interest thanks to its high esthetics and mechanical characteristics. This article describes, through a clinical report the use of Y-TZP based prostheses in long span fixed partial denture to restore function and esthetics.
