Composite resin restorative materials have been used in dental practice for over 25 years. The original composite resins were subjected to discolouration and marginal breakdown. These problems have largely been overcome with the exception of marginal gaps at the dentine-restoration interface. The introduction of dentine adhesives has reduced but not eliminate this problem. This study shows how the marginal gaps at the dentine-restoration interface were significantly reduced firstly by the introduction of an intermediate resin and then further by using a dentine adhesive.
复合树脂修复材料已在牙科临床应用超过25年。最初的复合树脂会出现变色和边缘破损问题。除了牙本质-修复体界面处的边缘间隙外，这些问题在很大程度上已得到克服。牙本质黏结剂的引入减少了但并未消除这一问题。本研究表明，首先通过引入一种中间树脂，然后进一步使用牙本质黏结剂，牙本质-修复体界面处的边缘间隙如何显著减小。
