Patient: A 79-year-old woman had masticatory disorders due to inadequate mandibular complete dentures. The maxilla was fitted with Kennedy class 1 removable partial dentures and a panoramic radiograph showed a defect in the right mandibular condyle. The mandible had a discord in the facing relationship with the upper jaw and severe ridge resorption.
Discussion: It was judged that the right deviation of the mandible due to the defect of the right mandibular condyle caused a decrease in the retention of the entire mandibular denture, and piezography was performed when manufacturing the therapeutic denture. It is considered that the maintenance of the entire mandibular denture was improved by setting the artificial tooth arrangement and the denture base polishing surface morphology in the neutral zone.
Conclusions: Retention and stabilization of the denture were effectively achieved by paying attention to the arrangement position of the artificial teeth and morphology of the polished surface.
