【Abstract】 ABSTRACTThe wear resistance of restorative materials is extremely important parameter. Since 1970s, many people effort to find a method and equepment for evaluating clinical wear resistance of restorative materials, but up to now it’s not successful. In this study an abrasive test machine was developed. According to abrasive mechanism in vivo soft abrasive material was used. From testing four kinds of filling materials, it’s observed clearly that their wear rate of volume were identical with clinical results in order of magnitude. The microstructure of wear surface were quite cimilar to clinical results.更多还原
