Abstract
This case report describes the orthodontic treatment of a 29-year-old male who lost the maxillary bilateral central incisors as a result of a traffic accident. After emergency treatment for facial fracture by a plastic surgeon, the patient visited our orthodontic clinic. He had a concave profile, Class I molar relationship with slight maxillary retrusion, and crossbite of the maxillary bilateral lateral incisors. The interdental space was insufficient for prosthetic treatment of the missing maxillary incisors. Therefore, we planned to distalize the maxillary and mandibular molars to obtain appropriate interdental space for the prosthetic treatment of the missing teeth and to correct the crowding of the mandibular anterior teeth. The anterior crossbite was corrected, and appropriate overjet and overbite were obtained with functional occlusion after prosthetic treatment. This case report shows that the favorable occlusion and facial profile are obtained by the interdisciplinary treatment and discusses the specific problems which seen after the traffic accident.
