Odontomas are hamartomatous lesions or malformations rather than true neoplasms which are
generally asymptomatic. Making up 22% of all odontogenic tumors of the jaw, it is the most
prevalent benign odontogenic tumor. It can be either compound or complex odontoma.
Complex odontomas do not resemble teeth at all, whereas compound odontomas, which are
composed of calcified tissues which resemble tooth. Odontomas usually are diagnosed
accidentally on routine radiographic examination. Complex odontomas are frequently found in
the posterior mandible. We report the case of unusually large sized complex odontoma in right
posterior mandible which had been successfully managed by surgical excision by multiple
separated blocks via intraoral approach to prevent pathological fracture of mandible and
avoiding extraoral incision which leads to unwanted extraoral scar.
