Until now, the ability to fabricate definitive Cerec bridges for the posterior region was less a question of the capabilities of the Cerec software than the availability of ceramic materials with sufficient strength for these indications. With the launch of the somewhat translucent inCoris TZI zirconia, Sirona has made possible the computer-assisted design and computer- assisted manufacturing (CAD/CAM) of monolithic bridges using Cerec dental software. In this article, the possibilities and limitations of inCoris TZI, as well as inCoris TZI C (a recently introduced further development from Sirona), will be demonstrated, based on two clinical cases. Keywords: Cerec bridges, zirconia, esthetics with zirconia, inCoris TZI, inCoris TZI C
