A 30‐Year Follow‐Up of a Patient with Mandibular Complete‐Arch Fixed Implant‐Supported Prosthesis on 4 Implants. A Clinical Report

Abstract

Mandibular complete‐arch fixed implant‐supported prostheses are recognized as one of the earliest and most popular prostheses in implant dentistry. This prosthesis was the main focus in the early era of osseointegration. Despite its widespread popularity, few clinical reports exist have described long‐term follow‐up greater than 10 years for this type of prosthesis. This report describes a 30‐year follow‐up of a patient who underwent treatment for a mandibular complete arch fixed implant‐supported prosthesis with 4 machined surfaced implants, opposing a maxillary complete denture. This report documents a variety of photographs and radiographs taken over a period of 30 years to compare bone levels at various stages of care and maintenance, including de novo bone formation underneath the distal cantilevers due to functional loading. The biologic and biomechanical response to this treatment protocol and long‐term clinical observations and prosthodontic outcome and maintenance needs are also addressed.
