Restorative approach in prosthetic rehabilitation of unilaterally resorbed maxillary edentulous ridge and partly resorbed mandibular edentulous ridges: A case report

Abstract

Introduction. The aim of this study was to fabricate a complete upper acrylic denture and a partial lower acrylic denture and provide occlusal rehabilitation with added benefit of correcting the position of altered condyle in a dysfunctional stomatognathic system. Case Report. Procedures for fabrication of acrylic dentures are thoroughly described. Specific scheme of occlusion was applied in the treatment of this patent. Occlusal contacts were established as tripod minor contacts on the side where the part of upper edentulous ridge was intensively reduced (on the right side) with divergent tracing of the condyle due to dysfunction. Tripod contacts were established on occlusal surfaces of opposing teeth as well. Contacts on the left side were formed as circumferential surfaces. Specially distributed occlusal contacts favorably influenced reduction of occlusal stresses on supporting tissues in the mouth of the patient. Tooth contacts arranged in such particular order were established to redistribute loading as well as to prevent excessive propulsion and latero-protrusive movements of the lower jaw. Conclusion. Occlusal pattern of tripod and single-point contacts was used to compensate differences in condylar movements of this patient with stomatognathic dysfunction, intending to diminish loads on reduced surfaces.
