This article describes the diagnosis and treatment of a skeletal Class II adolescent patient with a chronic finger sucking habit. A 13-year-old girl presented with a chief complaint of lip protrusion. Since she also had a severe thumb sucking habit, maxillary anterior segmental osteotomy was planned to not only change her profile but also abruptly change the oral environment to stop the chronic thumb sucking habit. After treatment, the habit disappeared, and the facial profile was improved. And uprighting of the maxillary incisors, posterior movement of the molars, and labial inclination of the mandibular incisors were observed. When treating a Class II patient with a large overjet that has persistent severe thumb sucking, surgery could be a good option to not only correct the malocclusion but also actively control the habit.
