采用两种不同尺寸的磨粒抛光，考察了微细填充复合树脂和普通复合树脂的耐磨性。对复合树脂的力学性能与磨损的关系进行了研究和评价。常规复合材料的耐磨性远低于微填充树脂。含10ƒ纳米碳化硅颗粒的银汞合金和人牙釉质具有最强的耐磨性，而含20ƒ纳米碳化硅颗粒的银汞合金和牙釉质的耐磨性与微填充树脂相当。磨粒大小对磨损的影响因材料不同而不同。填料含量、努氏硬度、弹性模量、破坏能等力学性能与磨损率有很好的相关性。
The wear resistance of microfilled and conventional composite resins, was examined, using two sizes of abrasive particles for polishing. The mechanical properties of the composite resins were also studied and evaluated in relation to wear. Conventional composites showed much lower wear resistance than the microfilled resins. The amalgam and human enamel abraded with 10ƒÊm SiC particles, had strongest wear resistance, and those abraded with 20ƒÊm SiC particles had resistance similar to that of the microfilled resins in wear. The effect of the size of the abrasive particles on wear differed with the material tested. Filler content, the mechanical properties of knoop hardness, elastic modulus and destructive energy correlated well with wear rate.
