The procedure developed in this investigation is suitable for determining the abrasion resistance of restorative materials to toothbrush/dentifrice abrasion. Ideally, a restoration should have an abrasion resistance similar to that of enamel. Of the materials tested, gold was the only one that wore slightly less than enamel, whilst amalgam wore almost twice as quickly. The silicate material and composites (excluding TD.71) wear away 2-4 times faster than enamel. TD.71 and especially the unfilled resin exhibited very high rates of abrasion. After prolonged toothbrush/dentifrice abrasion, the surfaces of gold and amalgam were considerably smoother than those of the silicate and composite materials.
本研究中开发的程序适用于测定修复材料对牙刷/牙膏磨损的耐磨性。理想情况下，修复体的耐磨性应与牙釉质相似。在测试的材料中，金是唯一磨损程度略低于牙釉质的材料，而汞合金的磨损速度几乎快两倍。硅酸盐材料和复合材料（不包括TD.71）的磨损速度比牙釉质快2至4倍。TD.71，尤其是未填充树脂的磨损率非常高。经过长时间的牙刷/牙膏磨损后，金和汞合金的表面比硅酸盐和复合材料的表面光滑得多。
