Ameloblastoma is a slow-growing, persistent, and locally aggressive  neoplasm arising from the odontogenic epithelium. Only 10 percent of ameloblastomas occur in the anterior mandible. We present a case of an anterior mandibular ameloblastoma that was previously histpathologically diagnosed as a dentigerous cyst. Patient underwent wide surgical excision of the tumor followed by immediate reconstruction using non vascularized autogenous graft from the anterior ileum, stabilized with titanium reconstructive plates. A brief case report and review of literature is presented.
