Rehabilitating Compromised Dentition With All-on-6: A Multidisciplinary Clinical Approach

Chandrama Pratap et al. Cureus. .

Abstract

This case report describes the rehabilitation of a patient using an implant‑supported fixed prosthesis in the mandible and a three‑unit fixed partial denture in the maxilla, following the extraction of periodontally compromised teeth. Six endosseous implants were placed in the mandibular arch, achieving favorable primary stability. The postoperative and maintenance phases were uneventful, with no biological or mechanical complications observed. The maxillary arch was restored with a tooth‑supported fixed partial denture, planned to optimize both esthetics and function. At the four‑month follow‑up after delivery of the mandibular prosthesis, clinical evaluation confirmed the biological health of peri‑implant tissues, biomechanical integrity of the restoration, and proper occlusal function. The patient reported high satisfaction with both esthetic and functional outcomes. For the definitive prostheses, direct metal laser sintering cobalt‑chromium frameworks veneered with ceramic were employed, owing to their advantages of precise marginal adaptation, favorable mechanical properties, and predictable long‑term performance.

Keywords: all-on-6 concept; direct metal laser sintering (dmls); implant-supported mouth recuperation; mandibular fixed dental prosthesis; maxillary fixed partial denture.

Direct metal laser sintering (DMLS) is a form of 3D printing. This process uses a laser to fuse metal powder into a precise, customized shape, often titanium. This material is known for its strength, durability, and good fit.
