The correction of anterior open bite in dolichofacial individuals with magnetic forces has been studied. The attempt was made to intrude buccal segments by using interarch magnets set in repulsion in order to correct the anterior open bite of six dolichofacial patients. It was expected to intrude the posterior sections with these magnetic forces, to autorotate the mandible and to close the anterior open bite by decreasing the lower facial height and rotating the facial axis closed. The magnets were placed in each arch only on those teeth that needed intrusion, mainly second premolars and existing molars, for a period of 21 weeks on six patients with a vertical pattern and an anterior open bite. It was found that in this period of magnetic wear there was little or no intrusion of the buccal segments. There were no appreciable changes in the position of the facial axis. Three cases showed slight reduction of the anterior open bite independently of the magnetic forces. There was a problem with production of posterior crossbites which possibly were instrumental in reducing the intrusion capabilities of the magnetic forces. It was concluded that forces exerted by the magnets were great enough to result in tooth intrusion but design changes in the magnetic appliance were necessary to improve buccal section intrusion.
