Oral appliance for correcting class III problems of mandibular prognathism

摘要

An oral appliance (10), a system and a method for correcting malocclusions may cause teeth and/or jaws of the patient to move into a corrected position. An upper body (12) and a lower body (14) of the appliance may be connected by a hinge. Lingual protrusions may extend rearward from the anterior portion (16) of the upper body and contact the maxilla of the patient when the appliance is worn. A protrusion may extend from the anterior portion (20) of the lower body forward relative to the mouth and contact the lips and exert a rearward force against the lower teeth.
