Severe Bilateral Mandibular Hyperplasia and Angle’s Class III Malocclusion in Indonesia: A Case Report

Malocclusion is an abnormal relationship between the teeth of the upper and lower jaws, with irregular tooth position, including crossbite and underbite. Malocclusion can occur in the form of crooked, protruding, or crowded teeth, affecting appearance, pronunciation, and mastication. Many factors lead to malocclusions, such as heredity, growth disturbance, and bad habits. Many Indonesians undergo orthodontic treatment to improve both function and appearance. The large demand for orthodontic treatment is due to increasing public knowledge about the impact of untreated malocclusion and the rising standard of living. We present a severe and rare case of malocclusion in Indonesia. A 20-year-old man presented with bilateral mandibular condylar hyperplasia and Angle’s class III malocclusion. A multidisciplinary team, including plastic and oral surgeons, orthodontists, and psychologists, was created to address this problem. The first surgical procedure was chosen to achieve correction in the shortest possible time. Le Fort I osteotomy and mandibular bilateral sagittal split and anterior subapical osteotomies using Kole’s procedure were performed. The patient underwent preoperative and postoperative examinations. After surgery, the occlusion was corrected and facial symmetry significantly improved.
