Abstract

Results and conclusions that can be drawn from this study are:1. All smooth, mesh, and seating preparation groups produced mean bond strengths significantly greater than that of the control group (p < 0.01).2. 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.3. Mean bond strengths for the electrolytically etched rest seat groups increased significantly at 30 days compared with the 24-hour means (p < .05).4. These results suggest that an electrolytically etched resin-bonded rest seat can easily withstand the functional stresses exerted by a removable partial denture.5. 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.
