A single-pass test was used to study the surface failure of commercial and experimental restorative resins and composites. The surface failure observed for unfilled diacrylate resins was more severe than that seen for an unfilled acrylic resin. Addition of nonsilanated filler to the diacrylate resins increased the resistance to penetration but did not dramatically change the mode of surface failure. The surface failure of the commercial composite resins, which contain silanated filler, was ductile in mode and the resistance to penetration of the diamond slider was the highest of the materials studied. The wear of restorative resins and composites is determined, therefore, by resistance to penetration as well as mode of deformation during sliding.
采用单通道试验研究商用和实验性修复树脂及复合材料的表面失效情况。未填充的二丙烯酸酯树脂观察到的表面失效比未填充的丙烯酸树脂更为严重。向二丙烯酸酯树脂中添加未硅烷化的填料可提高抗穿透性，但并未显著改变表面失效模式。含有硅烷化填料的商用复合树脂的表面失效模式呈韧性，且在研究的材料中，其对金刚石滑块的抗穿透性最高。因此，修复树脂和复合材料的磨损取决于抗穿透性以及滑动过程中的变形模式。
