Optimizing form and function with the direct posterior composite resin: a case report.

The acceptance of mercury-containing restorative materials has declined, and the demand for amalgam substitutes has resulted in development of a variety of composite resins. Microhybrids are the newest generation of composite resins, and they incorporate particles of different sizes to maximize wear, polishability, and handling characteristics. The learning objective of this article is to present a technique to maximize form, function, and aesthetics in the placement of a posterior composite resin restoration. Shade selection, use of caries indicator, "total etch" technique, new generation bonding agent, and incremental resin placement are discussed. A step-by-step case presentation demonstrates that an appropriately placed direct posterior composite resin provides an excellent alternative to the traditional metal-colored restorations.
