Mandibular Two-Implant Retained Overdenture: Prosthetic Design and Fabrication Protocol

Abstract

Among different treatment options, an implant-retained overdenture is a simple, cost-effective solution in the rehabilitation of the edentulous mandible. Despite wide-spread acceptance of the treatment, some controversies still exist with regard to the design of the overdenture, selection of the appropriate attachment system, and the most optimal techniques for the overdenture fabrication. In this article, the authors describe a mandibular overdenture retained by 2 freestanding implants placed in th anterior region of the mandible. The ovedenture design includes a metal-reinofrcing framework and uses prefabricated stock abutments and hinge-type resilient attachments for its retention. The proposed fabrication technique requires a minimal number of clinical appointments, and resilient attachments are incorporated into the overdenture in the laboratory.
