The Class III posterior composite restoration.

This conservative method of restoring proximal carious lesions in posterior teeth is not offered as an "alternative" to more familiar methods. Rather, in the author's view, anyone who embraces the philosophy of "minimal invasion" and respects the preservation of sound tooth structure should first consider a class III composite resin restoration for aesthetic treatment of proximal caries in posterior teeth before using any other more aggressive or complex cavity design. In the practice of conservative dentistry, the author feels that the conventional class II approach is the less desirable alternative.

Porcelain veneers. Problems and solutions.

Porcelain veneer restorations require close attention to detail from beginning to end. It is often prudent to go slowly when working with these cases. Patients receiving them have high expectations that go beyond considerations of function alone. Many problems are encountered when porcelain veneers are used to improve the appearance of the teeth. Avoiding and overcoming these problems first requires identification of the causes of the problems, followed by changes in clinical techniques. Success is the result of careful selection of teeth to receive veneers; preparing teeth in a manner that optimizes the aesthetic potential of the veneer; employing techniques that maximize the strength of both the veneer and its adhesive bond to the tooth; utilizing high-quality provisional veneers; insisting on a precision fit; and paying attention to the details of adhesive bonding protocols.
