Abstract

Medical records and Cone beam computed tomography of 20 patients with the diagnosis of temporomandibular joint ankylosis were included in the study.Results: Most of the patients presented with unilateral TMJ ankylosis (n=15, 75%) In unilateral ankylosis, the affected side ramus and body (4.89cm, 7.63cm respectively) were less than the non-affected sides (5.54cm, 8.15cm) respectively. Dentition crowding with malposed teeth was present in all bilateral TMJ ankylosis patients and 9 patients in unilateral cases.
