For composite resin and ceramic inlays there is little information about the survival of the luting agent. The purpose of this in vitro study was to relate the wear rate of the composite resin luting agent to interfacial gap dimensions and filler particle size. By controlling the gap dimension between the inlay and cavity preparation through use of the cement and horizontal gap width. It was confirmed that this relationship was linear. In addition, the inclination of the regression line was assumed to indicate the extent of wear. Therefore, the wear resistance of cements could be determined by determining this inclination. The results of this study revealed that two hybrid cements exhibited lower wear resistance than did a microfilled cement.
对于复合树脂和陶瓷嵌体，关于粘结剂存留率的信息很少。本体外研究的目的是将复合树脂粘结剂的磨损率与界面间隙尺寸和填料粒度联系起来。通过使用粘结剂和水平间隙宽度来控制嵌体与洞形预备之间的间隙尺寸。证实了这种关系是线性的。此外，回归线的斜率被认为表明磨损程度。因此，通过确定该斜率可以测定粘结剂的耐磨性。本研究结果显示，两种混合粘结剂的耐磨性低于微填料粘结剂。
