Composite denture teeth made on a removable partial metal framework.
Most denture teeth and denture bases are made of polymethyl methacrylate, which does not chemically bond with a metal framework. The absence of a chemical bond leads to weak retention and high microleakage between the resin and metal interface. With a 4-META bonding agent, a chemical bond that increases retention and decreases microleakage can be created between the composite and the metal interface. This article describes a method for making composite denture teeth with a 4-META bonding agent. It can be done without costly equipment and can also be used to repair acrylic resin denture teeth.
