The ceramo-metallic restorations have enjoyed increasing universal popularity as the restoration of choice where long-term esthetics is desirable. However, with the many variables that exist in fabrication and function of these restorations, there is also a potential for failure. This failure usually involves the porcelain portion of the restoration (Santos et al., 2006).
