Cementomas are benign jaw tumors that originate from periodontal ligament elements. Four classifications of cementomas are described: periapical fibrous dysplasia, benign cementoblastoma, cementifying fibroma, and florid osseous dysplasia. Usual treatment regimens vary from observation to limited surgical resection based upon tumor type and clinical characteristics. We present an unusual case report of an extensive cementifying fibroma that required mandibular and inferior alveolar nerve resection followed by osseous and neural reconstruction.
