The CICERO system for CAD/CAM fabrication of full-ceramic crowns

J Prosthet Dent. 2001 Mar;85(3):261-7. doi: 10.1067/mpr.2001.114399.

Abstract

The CICERO method of crown fabrication consists of optically digitizing a gypsum die, designing the crown layer buildup, and subsequently pressing, sintering, and milling consecutive layers of a shaded high-strength alumina-based core material, a layer of dentin porcelain, and a final layer of incisal porcelain. Final finishing is performed in the dental laboratory. The CICERO method allows efficient production of all-ceramic restorations without compromising esthetics or function. This article reviews the process involved in the fabrication of a CICERO crown.
