Abstract

The clinical performance of dental composites has been significantly improved over the past decade through modifications in formulation that include using more stable polymerization promoters for greater color stability, incorporating high concentrations of finely ground fillers to produce adequate strength and excellent wear resistance while retaining translucency, adding radiopacifying agents for improved diagnostics; and utilizing dentin adhesives. However, there are problems which limit the use of composites, especially in posterior teeth. The materials remain very technique-sensitive due to the extensive contraction which accompanies polymerization and negatively influences marginal sealing in addition, the materials are generally considered to have inadequate mechanical properties and wear resistance in contact areas to serve as total replacements for amalgams. Current efforts are focusing on several areas, including the development of non- or minimally-shrinking dental composites containing spiro-orthocarbonates as additives to dimethacrylates or epoxy-base resins, and the production of alternative filler materials for ideal wear resistance and esthetics. This paper reviews the composition and characteristics of current dental composites, as well as recent areas of study.
