A CASE OF BENIGN OSTEOBLASTOMA IN MANDIBLE TREATED BY INTRA-ORAL PARTIAL MANDIBULECTOMY WITH RESIN GRAFT

This is to report an uncommon case of Benign Osteoblastoma occured in left mandibular body of 19 year-old man. The authors treated the patient successfully by intra-oral partial mandibulectomy with resin graft, and examined histopathologically. The results are as follows; 1. Beingn Osteoblastoma is a vascular osteoid and bone-forming tumor which occured uncommonly in mandible, and has progressive swelling followed by pain. 2. In this case, it was impossible to treat the beign osteoblastoma with usual methods such as curettage and conservative resection, because the mass was hard, fused closely to the intact surrounding bone and extended to the inferior border of mandible. 3. We had a good functional and cosmetic result by an intra-oral partial mandibulectomy with resin graft, and could not seen any complications such as infection or rejection phenomena associated with resin allograft.
