Abstract

The wear resistance of newer esthetic restorative materials has generally improved, and the damage caused by several materials to the opposing dentition also has been reduced. However, the very different structure and physical properties of tooth substance and restorative materials will eventually lead to varying degrees of differential wear. The extent and rate of the wear are influenced by many intraoral factors. Selection of the most appropriate restorative materials must be based on the knowledge of their wear behavior and the individual needs of each patient. The lowest wear rates for restorations and the opposing dentition occur with metal alloys, machined ceramics, and microfilled and microfine hybrid resin composites.
