Although porcelain has predictably served the dental profession for more than 200 years, this class of restorative material has presented a number of clinically undesirable characteristics. As a result, during the past several years, major efforts have been made to enhance the mechanical and physical characteristics of polymers to better mimic porcelain for specific clinical applications. In recent years, Bis-GMA/barium-glass polymer systems have been developed to offer dental professionals a versatile restorative alternative to porcelain. This article details the material properties and clinical characteristics of one such system for the esthetic restoration of anterior and posterior teeth.
