ABSTRACT
Since prognostic indicators are likely to take on increasingimportance as a diagnostic tool for selection of patients forimplant provision, this study investigated the influence of theshape and resiliency of the mandibular alveolar ridge on theretention and stability of conventional complete dentures. Ninety-three edentulous patients wearing both maxillary andmandibular conventional complete dentures composed the sample.Data were collected regarding shape and resiliencyof themandibular residual ridge. Dentures were assessed for retentionand stability using an objective and reproducible tool.The associationsbetween the clinical characteristics of the mandibularalveolar ridge and denture retention and stability were analyzedusing chi-square and Fisher exact tests (α = 0.05). A significantassociation between ridge shape and denture stability (p < 0.05)was found, while ridge resiliency was significantly associated todenture retention (p < 0.001). Based on the results, mandibularridge shape and resiliency influenced the retention and stabilityof conventional complete dentures...
