title: Surgical Orthodontic Treatment for Open Bite in Noonan Syndrome Patient: A Case Report.
abstract: Noonan syndrome, characterized by short stature, facial anomalies, and congenital heart defects, may also be associated with hematopoietic disorders. Craniofacial anomalies in affected patients include hypertelorism and severe open bite associated with masticatory dysfunction. We treated a Noonan syndrome patient with a skeletal open bite. Surgical orthodontic treatment including two-jaw surgery established a good occlusal relationship after correction of severe anemia. Both upper and lower incisors were moved to upright positions, while clockwise rotation of the palatal plane and decreased mandibular plane angle were accomplished. Lower masticatory activity may affect posttreatment occlusion in such cases.
