In recent years, there has been an increase in number of patients with maxillofacial trauma due to traffic accident. If the patient has had the fracture of the maxilla with severely complicated trauma, generally, he is immediately transported to the emergency hospital and primary treatment may be done there. Consequently, some of them result in incomplete healing of the fracture.
Two cases, in this report, had open bite as a complication after treatment for maxillary fracture and were treated with Le Fort I osteotomy and mini-plate fixation. Following this secod operation, their occlusions have been recovered properly.
The main reason for their malocclusions was due to little consideration of the occlusions in primary treatment. These cases indicated the necessity of cooperation between the OMF surgeon and allied department faculty in primary treatment of maxillary fracture.
