Abstract
PURPOSE: Orthognathic surgery is generally used to correct facial deformities and establish functional occlusion. Preoperative orthodontic treatment is important for stabilizing and establishing the postoperative occlusion. However, sufficient preoperative surgical orthodontic treatment might be sometimes difficult in patients with an abnormally shaped maxilla or mandible or severe jaw deformity. METHODS: We performed this technique over 10 patients with jaw deformities after insufficient presurgical orthodontic treatment. Adhesive resins are attached to the maxillary palatal cusps to during surgery for disclusion of the premolars and molars. RESULTS: The resins which are interfered during the postoperative orthodontic treatment can be removed gradually with a bur. Postoperative orthodontic treatment can be subsequently facilitated with a stable occlusion. CONCLUSION: This technique should be applied for surgery-first orthognathic surgery and avoidance of multi-piece Le Fort I osteotomy, and can facilitate postoperative orthodontic treatment following gradually removal of cusp interferences.
