This in vitro study involving 84 caries-free molar specimens examined the resistance of complex amalgam restorations retained by two dentin bonding agents--Amalgambond and Amalgambond Plus--four regular TMS pins, six regular TMS pins and four pins in conjunction with Amalgambond. Analysis indicated that the Amalgambond restorations were significantly weaker than the other types. Amalgambond Plus restorations were significantly stronger than the Amalgambond restorations but not different from the remaining groups. The authors concluded that complex amalgam restorations should be retained with a combination of adhesive and mechanical retention.
这项涉及84个无龋磨牙标本的体外研究，检测了由两种牙本质粘结剂（Amalgambond和Amalgambond Plus）、四个常规TMS钉、六个常规TMS钉以及四个与Amalgambond联合使用的钉所固位的复合汞合金修复体的抗力。分析表明，Amalgambond修复体明显比其他类型的修复体弱。Amalgambond Plus修复体明显比Amalgambond修复体强，但与其余组无差异。作者得出结论，复合汞合金修复体应用粘结和机械固位相结合的方式进行固位。
