The aim of the present case report is to describe the orthodontic-surgical treatment of a 17-year-and-9-month-old female patient\nwith a Class III malocclusion, poor facial esthetics, and mandibular and chin protrusion. She had significant anteroposterior and\ntransverse discrepancies, a concave profile, and strained lip closure. Intraorally, she had a negative overjet of 5mm and an overbite\nof 5 mm. The treatment objectives were to correct the malocclusion, and facial esthetic and also return the correct function. The\nsurgical procedures included a Le Fort I osteotomy for expansion, advancement, impaction, and rotation of the maxilla to correct the\nocclusal plane inclination. There was 2mmof impaction of the anterior portion of the maxilla and 5mmof extrusion in the posterior\nregion. A bilateral sagittal split osteotomy was performed in order to allow counterclockwise rotation of the mandible and anterior\nprojection of the chin, accompanying the maxillary occlusal plane. Rigid internal fixation was used without any intermaxillary\nfixation. It was concluded that these procedures were very effective in producing a pleasing facial esthetic result, showing stability\n7 years posttreatment.
