Dental metal ceramic systems are designed for use when creating crowns, bridges and other ceramic dental restorations that feature metal substructures. These ceramic systems can be for either the layering technique or for press-to-metal restorations. In either case, the ceramic material is designed to bond well with the metal substructure while providing lifelike esthetics on the surface of the restoration. Different metal ceramics are compatible with different metal substructures so be sure the system you choose works with the metal used for the restoration framework.
