An adult woman with amelogenesis imperfecta, a skeletal Class III relationship, long face syndrome, and a severe anterior open bite received interdisciplinary treatment (orthodontics, orthognathic surgery, and prosthodontics). Presurgical orthodontic treatment was followed by a maxillary posterior impaction with anterior advancement and a mandibular setback. After surgery, the patient received ceramic crowns. Function and esthetics were successfully re-established. World J Orthod 2010;11:284–291.
