在过去的几年中，由于患者对用牙齿着色的牙齿替代物替换其金属牙齿替代物的需求增加，后部复合材料的使用增加。然而，直到最近，后复合材料还没有被认为是金属涂层的合适替代品，主要是因为它们在聚合过程中倾向于收缩，并且比传统的金属材料磨损更大。粘合剂和复合材料的改进现在使得生产不会产生过度长期磨损的后部复合材料成为可能。尽管有这些改进，临床医生可能会发现某些复合材料在某些患者中的磨损超过预期。通过对不同磨损机制的良好理解，临床医生可以熟悉临床磨损变化，并选择复合材料在没有过度磨损的情况下工作良好的临床病例。
During the past few years, the use of posterior composites has increased, due to an increased demand from patients to have their metallic restorations replaced with tooth colored restorations. However, until recently, posterior composites were not considered suitable alternatives to metallic restorations mainly because of their tendency to contract during polymerization and wear more than traditional metallic materials. Improvements in bonding agents and composite materials have now made it possible to produce posterior composites that may not produce excessive long-term wear. Despite these improvements, clinicians may find that some composites wear more than expected in certain patients. By developing a good understanding of the different wear mechanisms, the clinician can become familiar with clinical wear variations and select clinical cases where composites may work well without excessive wear.
