采用陶瓷（PO）、Au-Ag-Pd合金（PD）、直接修复复合树脂（CR）和牙釉质（TO）进行两体冲击滑动磨损试验，研究了冠桥复合树脂（ES）的磨损行为。虽然PO是最硬的，但在ES-PO的组合中，PO与ES的磨损最大，这可能是由它们撞击造成的表面破坏引起的。ES-PD的磨损量排在第二位。我们注意到，在这种组合中，ES的表面部分被刮薄的PD层污染，其程度可以用肉眼区分。ES与CR、TO或ES本身组合时，各部件的相互磨损相对较低。结果表明，混合复合树脂可作为后冠和后桥的替代材料，除非它与瓷或合金相对立。
The wearing behaviors of a hybrid composite resin for crown and bridge (ES) were examined using a two-body impacting-sliding wear test with a porcelain (PO), Au-Ag-Pd alloy (PD), direct restorative composite resin (CR) and tooth enamel (TO). Although PO was the hardest of all, it showed the largest wear together with ES in the combination of ES-PO, which was probably initiated from the superficial destruction by their impact. The wear in ES-PD was the second largest. It was noted in this combination that the surface of ES was partially contaminated by scraped thin layers of PD to a degree distinguished by the naked eye. The mutual wears of the components were relatively low in the combination of ES with CR, TO or ES itself. It is suggested from these findings that the hybrid composite resin may be useful as an alternative to porcelain for posterior crown and bridge unless it opposes porcelain or alloys.
