There is an increasing incidence of oncological pathology in the maxillofacial region today. Osteosarcoma is the second most common malignant bone tumour after bone marrow tumours. Osteosarcoma in the jaw and facial region may lead to a series of complex reconstructive operations, prolonged postoperative periods, complications of surgical interventions, long-term pain syndromes, craniofacial deformities, and functional, aesthetic, and sensory impairments. A 22-year-old female patient diagnosed with jaw osteosarcoma underwent partial mandibulectomy followed by surgery involving bone graft from the fibula and a mucocutaneous flap., On presentation to the Faculty of Dentistry the patient had tooth number 36 present intraorally, with the mandibular symphysis region reconstructed using a dermal flap. Six implants were planned for the patient. After 3 failed, a fixed and removable sectional prosthesis with precision attachments and clasps was planned using the remaining 3 implants and tooth number 36. The difference in density of the fibula bone compared to the mandible arises from the much greater density of the medullary cavity in the mandible. Additionally, the geometric differences in the cross-sectional anatomy of the fibula have been reported in the literature to potentially affect implant survival. It is speculated that the implant failure in this case may be due to this reason. In patients with difficulties in rehabilitation due to bone and tissue loss following complex surgeries such as mandibulectomy, both tooth-supported and implant-supported fixed and removable partial dentures can be beneficial.
