Combined surgical-orthodontic and prosthetic treatment of a partially edentulous patient with skeletal Class III malocclusion

Abstract

Purpose This article aims to showcase the effects and benefits of a multidisciplinary treatment approach incorporating orthodontics in adult patients with jaw deformities and partially edentulous jaws. We present a case of a skeletal Class III patient with partially edentulous jaws treated through a combination of surgical-orthodontic and prosthetic procedures.Materials and Methods A 49-year-old female patient sought treatment at our clinic for prosthetic care post root cyst extraction and improvement of her mandibular protrusion. She presented with a skeletal Class III malocclusion, facial asymmetry, maxillary distal extension defect, and mandibular intercalary defect.Results The patient underwent preoperative treatment with multi-bracket appliances to correct dental decompensation of the mandibular incisors and upright the mandibular molars. Subsequently, she underwent a bilateral sagittal split ramus osteotomy, with the mandibular setback of 8 mm on the right side and 4 mm on the left side. Prior to surgery, treatment dentures were fabricated for the defect, and post-surgery, these dentures, along with an occlusal splint, were secured with intermaxillary fixation screws and the remaining teeth. The interdental space in the mandibular anterior teeth was closed by postoperative treatment. The preoperative treatment lasted for 7 months, the hospital stay was 14 days, and the postoperative treatment continued for 6 months.Conclusion The successful treatment of this patient with jaw deformity and a partially edentulous jaw was achieved through the collaborative efforts of orthodontics, oral surgery, and prosthodontics departments.
