An American Board of Orthodontics case report. Treatment of an open bite malocclusion.
The patient had a Class I (Angle) malocclusion characterized by an anterior open bite, bimaxillary dental protrusion, posterior and anterior crossbites, and mandibular midline deviation. A nonextraction treatment was followed for this patient. A Begg appliance (0.020 inch) and a posterior high-pull headgear were used. The prognosis was good because of the rather favorable skeletal pattern of the patient. The active treatment lasted 12 months. The patient was retained with a positioner. The occlusion was stable at 2 years posttreatment.
