MAGNETIC ORTHODONTIC APPLIANCE ABSTRACT OF THE DISCLOSURE This invention relates to an orthodontic appliance for exerting a corrective magnetic force on live teeth in a patient's mouth. The appliance include two separate rigid caps having internal shapes conforming to the crown portions of juxtaposed teeth in the maxilla and mandible, respectively. The caps are adapted to be removably frictionally secured to such teeth. Two permanent magnets carried by the two caps, respectively, have facing poles which are in registry when the mouth is normally closed and further exert a magnetic force in a direction substantially normal to the occlusal plane. The poles are of extended area such that at least portions thereof remain in juxtaposed registry and the magnetic force maintains substantially in the same direction for normal relative jaw movement.
