    Ceramic systems for CAD CAM
    (Universidad Privada Norbert Wiener, 2019-11-22) Rojas Daza, José Santos; Kobayashi Shinya, Arturo
    The evolution of computer-assisted ceramic systems has brought about changes and new treatment options available for patients. Dental ceramics and processing technologies have evolved over the past ten years, with most of the development being related to new microstructures and CAD-CAM methods (Computer-Aided Design, Computer-Aided Manufacturing). Among these, we have lithium disilicate, zirconia, and a composite material made of a polymer infiltrated with ceramic. Furthermore, there has been a trend toward the use of monolithic restorations, which has changed the clinical production route for fully ceramic dental prostheses, as multi-layered restorations, while more aesthetic, are unfortunately more prone to chipping or delamination. Ceramic abutments on implants, made with Yttrium-stabilized zirconium oxide, have been developed for their color and load resistance, helping to maintain aesthetics on the implant. The development of composite materials with ceramic reinforcement processed via CAD-CAM has become an interesting option, as they have intermediate properties between ceramics and polymers and are easier to mill and polish than others, while maintaining strength values and wear potential against antagonistic enamel similar to dental tissues.
