Wear resistance of composite veneering materials was evaluated in vitro using a tooth brush wear testing device as well as a three-body wear testing machine. Composite resin veneered metal casting specimens were prepared using metal adhesive promoter. Wear resistance of the resin-metal interface was evaluated by means of the two wear testing devices. Wear resistance of the interface considerably improved through the use of a metal adhesive agent that contain thiol derivative monomer. Wear testing also revealed that both particle size distribution and sdhesive bonding between the filler particles and the matrix resin affected wear resistance of the materials. On the basis of these findings, it is concluded that wear resistance of composite resin veneered restorations can be improved with the use of appropriate adhesive promoter at the materials interface.

采用牙刷磨损试验机和三体磨损试验机对复合贴面材料的耐磨性进行了体外评价。采用金属粘结促进剂制备了复合树脂贴面金属铸造试件。通过两种磨损试验装置评价了树脂-金属界面的耐磨性。通过使用含有硫醇衍生物单体的金属粘合剂，界面的耐磨性显著提高。磨损试验还表明，颗粒尺寸分布和填料颗粒与基体树脂之间的粘结影响材料的耐磨性。在此基础上，得出结论：在材料界面处使用适当的粘合促进剂可以提高复合树脂贴面的耐磨性。
