ABSTRACT

Resin composite consists of a resin matrix and filler particles coated with an interfacial bond. They can be classified in a variety of ways, most usefully on the basis of the size of the filler particles. Resin composite is now the materials of choice for many restorations, including most occlusal cavities. The successful use of resin composite requires meticulous attention to enamel bonding, which will be described. In the long term, resin composite will have an increasing use in posterior approximal cavities, not only because of patient demands but also because of environmental concerns regarding mercury. This program will focus particularly on the use of resin composite in posterior teeth, by identifying the main problems and describing clinical strategies to overcome these problems. The clinical performance of resin composites in posterior teeth will be discussed.

OUTLINE
This program consists of approximately 45 slides which describe resin composites and their successful use, particularly in posterior teeth.

LEARNING OBJECTIVES
At the end of the lecture, participants will be able to:

• understand the classification of resin composites
• understand the rationale and techniques of bonding to enamel
• identify the main problems of using resin composite in
  posterior teeth
• be familiar with strategies to overcome these problems.
