2-1. GENERAL

Because of its esthetic properties, resin can be used for the reproduction of lost tooth structure. The dental officer prepares the cavity in the tooth in the usual manner, inserts the plastic mixture directly into the cavity, and allows it to polymerize at mouth temperature. These materials are often referred to as direct-filling resins. Certain shortcomings in the physical properties of resins restrict their use when esthetics, such as the restoration of anterior teeth, are the principal concern. There are two types of direct filling resins. The older type is an unfilled polymethyl methacrylate. Such a resin is often referred to as an acrylic resin. The newer type is the composite resin.
