This case report describes a successful orthognathic treatment with minimal presurgical orthodontics and bilateral extraction of maxillary second molars. A 21-year-old man had mandibular prognathism. His maxillary second molars were bilaterally extruded because there were no opposing teeth. After minimal presurgical orthodontic treatment with bilateral extraction of maxillary second molars to prevent immediate premature contact after surgery, we performed Le Fort I and bilateral intraoral vertical ramus osteotomy to correct the patient’s mandibular prognathism. During the postoperative orthodontic treatment, maxillary third molars were aligned to replace the bilaterally extracted maxillary second molars. The total treatment period was 14 months. As a result of these treatments, the patient’s facial appearance was rapidly improved. The minimal presurgical orthodontic treatment can guarantee immediate stable occlusion after surgery and achieve a rapid aesthetic improvement in skeletal Class Ⅲ patients.
