The tensile bond strengths of a resin cement, Panavia Ex, to a spherical and an admixed amalgam were measured after surface treatment with different aluminum oxide abrasive spray procedures. The type of amalgam and the brand of aluminum oxide affected the bond strength of the resin to amalgam alloy. When the spherical alloy was air abraded using 60-microns aluminum oxide prior to cementation of a Rexillium rod using Panavia, the bond strength was not significantly different from the previously reported bond strengths of Panavia to etched enamel. Significantly lower bond strengths were obtained between Panavia and the admixed amalgam alloy. These results suggest that it may be possible to place a resin-bonded prosthesis on an abutment tooth that has been restored using a spherical amalgam alloy.
采用不同的氧化铝喷砂处理程序对表面进行处理后，测量了树脂水门汀Panavia Ex与球形银汞合金及混合型银汞合金之间的拉伸粘结强度。银汞合金的类型和氧化铝的品牌会影响树脂与银汞合金的粘结强度。当在使用Panavia粘结Rexillium棒之前，使用60微米的氧化铝对球形合金进行空气喷砂处理时，其粘结强度与之前报道的Panavia与酸蚀牙釉质之间的粘结强度无显著差异。在Panavia与混合型银汞合金之间获得的粘结强度明显较低。这些结果表明，在使用球形银汞合金修复的基牙上放置树脂粘结修复体可能是可行的。
