ABSTRACT:
An orthodontic appliance is provided which has a buccal shield, an occlusal plate, a lingual flange for the incisors and slots for receiving the posterior teeth. The posterior segment of the appliance is preformed wider than the patient's lateral posterior teeth spacing and the slots are open lingually to permit the patient's tongue to press against the lingual surface of the posterior teeth to cause them to expand buccally. The slots are angled posteriorly to cause the posterior teeth to move distally.
