Orthognathic surgical approach and partial glossectomy to a skeletal 3 adult open bite.

Combined orthodontic treatment with orthognathic surgery and partial glossectomy were simultaneously performed in an adult male patient with mandibular prognathism and open bite from the lower right to the left first molars. Total active treatment period was 15 months. During the retention period, a tooth positioner was given to obtain proper interdigitation from set-up models. The post-surgical occlusion has been stable without any complication of the mandible and the tongue.
