This in vitro study compared three methods of surface treating gold alloys to improve resin adhesion. The tensile bond strengths and modes of failure between specimen pairs cemented with a chemically adhesive resin were recorded. Heat-treated gold alloy specimens were significantly more resistant to bond failure under tensile loading than were either alumina-blasted or tin-plated gold specimens. There was no statistically significant difference in bond failure between alumina-blasted and tin-plated gold specimens. The surface treatment altered the mode of failure from adhesive and/or adhesive-cohesive for alumina-blasted and tinplated gold specimens to cohesive (within the resin) for heat-treated gold specimens. Three case reports are presented to illustrate clinical applications of heat-treated gold alloys.
这项体外研究比较了三种表面处理金合金以改善树脂黏附力的方法。记录了用化学黏合树脂黏结的样本对之间的拉伸黏结强度和失效模式。在拉伸载荷下，热处理的金合金样本比经氧化铝喷砂处理或镀锡的金样本对黏结失效的抵抗力显著更强。经氧化铝喷砂处理的金样本和镀锡的金样本在黏结失效方面没有统计学上的显著差异。表面处理使经氧化铝喷砂处理和镀锡的金样本的失效模式从黏附性和/或黏附-内聚性转变为热处理金样本的内聚性（在树脂内部）。现呈现三个病例报告以说明热处理金合金的临床应用。
