The Role of Orthodontics for Patients with Maxillofacial Bone Fracture Due to Trauma

Abstract

　　The purpose of this study was to retrospectively evaluate the records of patients who were treated at the orthodontic clinic in order to improve jaw deformity and malocclusion that occurred after maxillofacial fracture due to trauma. There were 11 patients（6 males and 5 females）who ranged in age from 9 to 44 years, with an average of 26.5 years. The most frequent causes of trauma were traffic injuries in 9, followed by sports injuries in 2. Of these patients, 8 had a fractured mandible, 7 had a fractured maxilla, and 4 had a fractured maxilla and mandible. The treatments performed at the orthodontic clinic included comprehensive orthodontic treatment for 4, surgical orthodontic treatment with two-jaw surgery and preparation of surgical splints for 3, and manual removal of incomplete dislocation of teeth, limited orthodontic treatment, and mandibular setback surgery for one patient each. Furthermore, after orthodontic treatment, there were many patients who required additional residual surgery, and the maximum was 11 times. In order to prevent jaw deformity and malocclusion after maxillofacial fractures due to trauma, involvement of an orthodontist to reduce maxillofacial fractures is desirable.
