[Restoring esthetics and function of posterior teeth using direct composite restoration].
The growing demand for esthetic restorations in the posterior segments and the reports from all over the world concerning the possibility of a toxic effect of amalgam brought to the development of the composite resin materials. These allow excellent esthetic results without compromising the quality and long-term stability of the restorations. Out of the various types of posterior esthetic restorations, the most available are the direct ones. There are several substantial differences between fabricating amalgam or posterior composite restorations. The most significant difference concerns bonding to the tooth structures. The key to success in these restorations is the understanding of the reasons for failure, and the ways to prevent them. The failures are divided into two groups: biological failures--namely secondary caries, and mechanical failures--namely fracture and abrasion. The other key is understanding the materials used and their proper handling. This article illustrates in detail a step-by-step procedure the sequence of fabricating a posterior composite restoration in a posterior mandibular tooth, describing both techniques and materials used.
