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.

UI	MeSH Term	Description	Entries
D008670	Metals	Electropositive chemical elements characterized by ductility, malleability, luster, and conductance of heat and electricity. They can replace the hydrogen of an acid and form bases with hydroxyl radicals. (Grant & Hackh's Chemical Dictionary, 5th ed)	Metal
D008689	Methacrylates	Acrylic acids or acrylates which are substituted in the C-2 position with a methyl group.	Methacrylate
D001840	Dental Bonding	An adhesion procedure for orthodontic attachments, such as plastic DENTAL CROWNS. This process usually includes the application of an adhesive material (DENTAL CEMENTS) and letting it harden in-place by light or chemical curing.
