Osteoblastoma is a solitary benign bone-forming neoplasm, which comprises 1% of all primary bone tumors. Multifocal benign osteoblastoma of the jaws is very rare. Osteoblastoma must be differentiated from other similar bone-forming lesions such as osteoid osteoma and osteosarcoma for correct diagnosis and proper treatment planning. Therefore, precise examination of the patient and correlation with radiographic and histological features are essential for the best treatment and prognosis. This study reports a rare case of multifocal osteoblastoma in a 30-year-old female, involving the mandible and the maxilla, which was treated by surgical excision, iliac bone graft reconstruction, and implantation. Complete surgical excision is necessary to treat osteoblastoma with a good prognosis. The patient was followed-up for four years postoperatively, and there were no signs of recurrence in the panoramic view or the clinical examination.
