ORAL REHABILITATION OF A PATIENT WITH IMPLANT SCREW-RETAINED FIXED MANDIBULAR COMPLETE DENTURE: A HYBRID PROSTHESIS (FP- 3): A CASE REPORT

Abstract

The hybrid denture is a fixed-removable prosthesis resembles a flangeless denture that is retained solely by several Osseo integrated implants. There is no contact between the prosthesis and the tissues of the alveolar ridge. The anterior part of a mandibular hybrid denture is fixed on implants while the posterior part of the denture is extended and cantilevered from the most distal implant. Framework was waxed, plastic castable abutments were used, abutments casting was done after checking passive fit of plastic, denture teeth were waxed to the hybrid framework and a final wax try-in was performed to verify and correct maxillomandibular relations before processing. This article presents the fabrication of a mandibular implant retained hybrid prosthesis on the five implants that were placed in the mandibular arch in the inter mental foramina region. The rehabilitation of edentulous patients with hybrid dentures has been observed to achieve greater masticatory function and psychological satisfaction than with conventional over-dentures. Producing a passive fitting substructure for fixed removable screw retained hybrid prosthesis is one of the most technically complex tasks in implant dentistry.
