Abstract

Bond strengths of an adhesive resin bonded to two types of gold alloys were investigated in vitro with two different metal primers. Disk specimens were cast in a type IV gold alloy designed for resin-bonded restorations and in a low-temperature age-hardenable gold alloy. The specimens were primed with either a vinyl-thiol primer or a thiophosphate primer, then bonded with an adhesive resin initiated with tri-n-butyl borane derivative. Both primers effectively enhanced bond between gold alloys and the adhesive. The use of metal primers in conjunction with type IV gold alloys is useful for resin-bonded fixed partial dentures.

摘要

使用两种不同的金属底漆，在体外研究了一种粘结树脂与两种类型金合金的粘结强度。圆盘状试件用一种专为树脂粘结修复设计的IV型金合金以及一种低温时效硬化金合金铸造而成。试件分别用乙烯基硫醇底漆或硫代磷酸酯底漆处理，然后用由三正丁基硼烷衍生物引发的粘结树脂进行粘结。两种底漆均有效增强了金合金与粘结剂之间的粘结。将金属底漆与IV型金合金配合使用，对树脂粘结固定局部义齿很有用。
