Ortho-surgical management of skeletal class III malocclusion: A case report

Abstract

18-year-old female, presented with c/c of forwardly placed lower jaw. Extraorally, the patient had a symmetrical face and concave profile, competent lips, positive lip step, and obliterated mentolabial sulcus. Intraorally, the patient had Angle’s class III malocclusion with an overjet of (–5) mm, overbite of 0%, and cross-bite with respect to 15,12, 11, 21, 22 and upper and lower midline shift. The patient was skeletal class III due to prognathic mandible with hypodivergent growth pattern, and proclined upper and lower incisors. The patient was managed ortho-surgically with bijaw surgery (maxillary advancement 4mm + mandibular setback 7 mm) after presurgical decompensation. This case report discusses in detail the diagnosis and comprehensive management of the skeletal class III case.
