Occlusion and restorative materials.
Undoubtedly, the materials used in conjunction with restorative dentistry have been changing over the years. Although restorative systems before the early 1960s have changed only moderately, the last two to three decades have witnessed some fairly dramatic developments. Composite resins, mercury-free alloys, quartz-free ceramics, and gold-reduced or gold-free alloys represent some of the more obvious introductions. Considerable information has been made available concerning their physical and mechanical characteristics; however, little has been published concerning their effect on occlusion and equilibration of the teeth.
