CAD-CAM processing for all ceramic dental restorations

Abstract

High-strength ceramic materials such as polycrystalline alumina and zirconia-based ceramics can be used for the fabrication of various implant- or teeth-supported prostheses. Zirconia based ceramics can be successfully used for multiple unit – long span bridges or allow for the thickness reduction of the restorations in non-critical bio-mechanical situations. These materials have been introduced in dental practice, along with new technologies like the computer-assisted design/computer-assisted manufacturing (CAD/CAM) of dental restorations.
