Abstract : Mandibular distal extension partial edentulism presents by significantly biomechanical and functional challenges faced at the time of prosthetic rehabilitation because of the difference in support provided by the abutment teeth & residual ridge tissues. When implant supported prostheses or permanent restorations are impractical, the cast partial dentures (CPDs) continue to be a dependable and affordable treatment option for partial edentulous arches. In reference to 36, 37, and 47, the current clinical study details the prosthodontic rehabilitation of a partial edentulous mandibular arch employing a digitally created cobalt chromium CPD framework which was made to replace the missing teeth. Prosthesis insertion, jaw connection procedures, digital framework design, surveying, mouth preparation, framework production, and diagnostic assessment were all done in accordance with accepted biomechanical principles. To provide the best possible support, retention, stability, and advantageous stress distribution, the mandibular framework included a lingual bar major connector, occlusal rests, lattice minor connectors, proximal plates, and circumferential clasp assemblies. To improve mastication, occlusion, and patient comfort, acrylic denture teeth were positioned over the distal extension denture bases. During a follow-up review, the final prosthesis showed adequate retention, stability, aesthetics, and functional efficiency. In order to successfully rehabilitate mandibular partly edentulous arches with cast partial dentures over the long term, this case report emphasises the need for appropriate framework design and biomechanical planning. During follow-up, the cast partial denture showed better mastication and no soft tissue complications, with good retention, stability, functional efficiency, and patient comfort. For mandibular distal extension partial edentulism, digitally generated cobalt-chromium cast partial dentures provides a dependable, affordable, and efficient treatment alternative that guarantees the positive functional outcomes with patient satisfaction.
