Segmental resections of the mandible resulting in discontinuity defects, present with a number of complications that hinder an optimal prosthetic rehabilitation of such defects. Re-establishment of continuity using free tissue transfer can help one overcome many of these shortcomings. Restoration of the missing dentition in such cases must be in the way of a stable prosthesis to combat the limited denture bearing area and non-keratinised tissue bed. An implant supported prosthesis depends on the availability of adequate bone height, alignment of the grafted bone, crown height space, recurrence of the neoplasm, the requirement of or the passage of time since radiation therapy, physical condition of the patient and economic factors. An alternative is a stable cast partial denture designed to facilitate broad stress distribution to the unresected side, avoid damage to the graft and aid in function. This case report describes the prosthetic rehabilitation of a partially resected mandible secondary to ameloblastoma, reconstructed with a free fibula graft, using a cast partial denture.
