Full-Arch Implant Rehabilitation Using Multi-Unit Abutments in a Completely Edentulous Patient: A Clinical Case...

Implant-supported prostheses are a predictable treatment option for the rehabilitation of completely edentulous patients. When appropriate surgical and prosthodontic protocols are followed, they effectively restore function, esthetics, and occlusal stability. This case report describes the management of a 50-year-old male patient with complete maxillary and mandibular edentulism using implant-supported full-arch prostheses with multi-unit abutments (MUAs). Clinical and radiographic evaluation, including orthopantomogram and cone beam computed tomography, was performed for treatment planning. A total of 12 endosseous implants were placed, six in each arch, achieving a primary stability of 35 Ncm. Prosthetic rehabilitation was carried out using an open-tray impression technique, accurate jaw relation records, and passive framework verification. A screw-retained definitive prosthesis was subsequently delivered. All implants demonstrated successful osseointegration with satisfactory stability. The final prostheses exhibited good esthetics, functional occlusion, and improved patient comfort. The patient reported enhanced mastication and overall satisfaction. This case highlights that full-arch implant rehabilitation using screw-retained prostheses with MUAs is a reliable and predictable treatment approach for completely edentulous patients.
