The wear resistance of four proprietary posterior composite resins and amalgam were evaluated by an in vitro wear-testing system. Direct and indirect composite restorations were placed on occlusally flattened extracted molars. They were subjected to 400,000 cycles of artificial chewing. The vertical distance between the cavosurface margin and the worn occlusal surface, was measured to indicate the wear resistance of the restorative materials. The restorative systems, including a peroxide modifier, exhibited dramatic increases in wear resistance. The heat-treated composite inlay system exhibited minimal wear values compared to all other composite resins in the study. This system exhibited wear values that were less than those of the amalgam control group.
通过体外磨损测试系统评估了四种专利后牙复合树脂和银汞合金的耐磨性。将直接和间接复合修复体放置在咬合面磨平的拔除磨牙上。使其经受400,000次人工咀嚼循环。测量洞缘与磨损咬合面之间的垂直距离，以表明修复材料的耐磨性。包括过氧化物改性剂的修复系统表现出耐磨性的显著提高。与研究中的所有其他复合树脂相比，经热处理的复合嵌体系统表现出最小的磨损值。该系统的磨损值低于银汞合金对照组。
