The sliding-wear behavior of a number of commercially available microfilled and light-cured composite restoratives has been investigated and compared with the wear characteristics of conventional composites. The surface profiles of the composite restoratives, both pre- and post-test, have also been examined in order to study material attrition processes. The results indicate that: (1) microfilled composites are significantly more resistant to sliding wear than are restoratives containing conventionally-sized filler particles; (2) light-cured, microfilled composites exhibit a lower rate of sliding wear than do self-curing, microfilled restoratives; and (3) the wear process leads to an increase in surface roughness for all materials tested, but microfilled materials display lower surface roughness values, both before and after sliding-wear tests, than do restoratives containing conventional-sized filler particles.
已对多种市售微填料和光固化复合修复材料的滑动磨损行为进行了研究，并与传统复合材料的磨损特性进行了比较。为了研究材料磨损过程，还对复合修复材料在测试前后的表面轮廓进行了检查。结果表明：（1）微填料复合材料比含有常规尺寸填料颗粒的修复材料对滑动磨损的抵抗力显著更强；（2）光固化微填料复合材料的滑动磨损率低于自固化微填料修复材料；（3）磨损过程导致所有测试材料的表面粗糙度增加，但微填料材料在滑动磨损测试前后的表面粗糙度值均低于含有常规尺寸填料颗粒的修复材料。
