title: How some ridge shapes affect the fit of denture bases.
abstract: Polymerization shrinkage can result in poor denture fit. The aim of this study was to determine the accuracy of heat-polymerized acrylic bases on simulated edentulous metal ridges having simplified and standardized geometric configurations. Analysis of variance was used to explore the relationship between fit and ridge-slope/ridge-convergences. The outcome of that analysis revealed that the discrepancies between the base plates decreased significantly (p < 0.05) as both the ridge slope decreased and the anterior-sagital convergence increased. These geometric correlations can help clinicians to anticipate potential areas of sore spots on residual ridges when delivering complete dentures.
