Abstract

Introduction: This case report describes the surgical orthodontic treatment of a Class III young adult patient with transversal, sagittal and vertical skeletal discrepancy. Case Report: A male at age of 18 years sought treatment due to poor dentofacial aesthetics. He had a hyperdivergent face, skeletal Class III, mandibular prognathism, maxillary retrognathism, transverse deficiency, and dental crowding in both jaws. Treatment Progress: Orthodontic first stage decompensated the mandibular posterior teeth lingually inclined, and aligned maxillary molars and premolars. First surgery performed Le Fort I osteotomy to Surgical Assisted Rapid Maxillary Expansion (SARME). A second orthodontic stage created a negative overjet trough proclination of mandibular incisors. Double-jaw surgery performed Le Fort I osteotomy with maxillary advancement (5 mm) and impaction (4 mm), and Bilateral Sagittal Split Osteotomy (BSSO) with mandibular setback (3 mm). A third orthodontic stage achieved detailing of the occlusion. Treatment Results: At the treatment end, the patient showed improvement of dentofacial aesthetics, maxillary and mandibular teeth well aligned in dental arches with compatible form, proper intercuspation of posterior teeth, normal inter-incisors relationship, and normal function. The 3-years follow-up indicated treatment stability in short-term. Conclusion: Surgical orthodontic treatment with individualized sequence achieved successful results in a Class III young adult with transversal, sagittal, and vertical skeletal discrepancy
