Results and conclusions that can be drawn from this study are: All smooth, mesh, and seating preparation groups produced mean bond strengths significantly greater than that of the control group (p less than 0.01). The cast mesh rest seats exhibited significantly greater bond strengths at 24 hours (p = .0072). However, at 30 days, statistically significant differences between the three groups were not evident. Mean bond strengths for the electrolytically etched rest seat groups increased significantly at 30 days compared with the 24-hour means (p less than .05). These results suggest that an electrolytically etched resin-bonded rest seat can easily withstand the functional stresses exerted by a removable partial denture. The incorporation of seating preparation on an abutment tooth for an etched resin-bonded lingual rest seat seems to offer no advantage in terms of retentive strength.
所有光滑处理、网状处理和就位准备组产生的平均粘结强度均显著高于对照组（p小于0.01）。铸造网状支托就位座在24小时时表现出显著更高的粘结强度（p = 0.0072）。然而，在30天时，三组之间的统计学显著差异并不明显。与24小时均值相比，电解蚀刻支托就位座组的平均粘结强度在30天时显著增加（p小于0.05）。这些结果表明，电解蚀刻树脂粘结支托就位座能够轻松承受可摘局部义齿施加的功能应力。在邻牙上为蚀刻树脂粘结舌侧支托就位座进行就位准备，在固位强度方面似乎并无优势。
