实验室研究已经充分表征了用于熔瓷贴面的A110 ~ s。体外试验表明，某些基底金属和金合金在成分、机械性能、热性能、瓷-金属相容性、铸造精度和操作特性方面存在显著差异。尽管有广泛的实验室评估，关于测试的临床意义及其预测这些流行修复材料的长期临床性能的能力仍然存在争议。本研究的目的是评估两种基底金属合金Verabond（Aalbadent Corp.，Concord，Calif.）和Alpha MS（Omega Dental Co.，加利福尼亚州圣罗莎）。常规的金基合金Jelenko“0”（JF Jelenko Co.，阿尔蒙克，纽约州）作为比较和对照的基础。
A 110~ s intended for use with fused porcelain veneers have been well characterized by laboratory studies. In vitro tests have demonstrated significant differences between certain base metal and gold alloys in regard to their composition,‘-3 mechanical properties, 4-” thermal behavior,‘,* porcelain-metal compatibility,‘-‘” casting accuracy, and manipulative characteristics.‘7-‘3 In spite of extensive laboratory evaluation, controversy still exists regarding the clinical significance of the tests and their ability to predict the long-term clinical performance of these popular restorative materials.The objective of this study was to evaluate the clinical performance of two base metal alloys, Verabond (Aalbadent Corp., Concord, Calif.) and Alpha MS (Omega Dental Co., Santa Rosa, Calif.). A conventional gold-based alloy, Jelenko ‘0’(JF Jelenko Co., Armonk, NY), was used as a basis of comparison and control.
