This clinical report describes a functional and esthetic treatment using an implant-supported fixed detachable prosthesis for a patient who underwent resection and skeletal reconstruction due to mandibular osteosarcoma. A four-stage protocol was used that included resection and rigid fixation with a reconstruction plate, autogenous bone graft, placement of osseointegrated implants, and prosthetic restoration. The patient required a second resection because of the positive margin of the first resection. An autogenous bone graft was placed after the negative margin of the second resection was confirmed. Six months after the iliac crest bone graft, five implants were placed in the defective areas of the mandible. These implants were restored with a fixed detachable denture fabricated with a cast gold alloy framework. This functional and esthetic prosthesis has performed favorably without any problems for one and a half year.
