Posterior composites are becoming a viable alternative to amalgam in selected cases. As the use of posterior composites increases, the necessity of repair of fractured, discolored, or worn restorations will increase. A number of studies have demonstrated that clinically acceptable repairs can be obtained for anterior composites. This study examined the bond strength of repairs made to aged posterior composite substrates when different bonding agent/composite pairs were used. Dentin bonding agent/composite pairs gave the highest bond strengths and were greater than the bond strength of resin to etched enamel. An enamel bonding agent/composite repair gave the lowest bond strengths, which were less than resin/etched enamel bond strengths.
在某些特定情况下，后牙复合树脂正成为汞合金的一种可行替代物。随着后牙复合树脂使用的增加，修复折断、变色或磨损修复体的必要性也会增加。许多研究表明，前牙复合树脂能够获得临床可接受的修复效果。本研究考察了使用不同的粘结剂/复合树脂组合对老化后的后牙复合树脂基底进行修复时的粘结强度。牙本质粘结剂/复合树脂组合的粘结强度最高，且大于树脂与酸蚀釉质之间的粘结强度。釉质粘结剂/复合树脂修复的粘结强度最低，低于树脂/酸蚀釉质的粘结强度。
