Rehabilitation of a patient with Screw-Retained Metal-Resin Implant-Tissue Supported Fixed Mandibular Complete Denture: A Hybrid Prosthesis (FP – 3): A Case Report

Abstract

A hybrid denture is one that is fabricated over a metal framework and retained by screws threaded into the implants. The anterior part of a mandibular hybrid denture is fixed on implants while the posterior part of the denture is extended and cantilevered from implants. This article presents the fabrication of a mandibular implant retained hybrid prosthesis. A total of four implants were placed in the mandibular arch. Framework was waxed, plastic castable abutments were used, casting was done, denture teeth were waxed to the hybrid framework and a final wax try-in was performed to verify and correct maxillomandibular relations before processing. The prosthesis was inserted after verification of occlusion, retention and to cast recovered and the fit was refined until the framework seated passively on the master cast. The mandibular achieve greater masticatory function and psychological satisfaction than with conventional over-dentures. Producing a passive- fitting substructure for a fixed removable screw retained hybrid prosthesis is one of the most technically complex tasks in implant dentistry. The technique presented describes a step by step procedure for achieving a perfectly fitted mandibular hybrid prosthesis.
