Abstract
This orthodontic distalizing appliance includes a forward support assembly having an anchoring base in the roof of the mouth. A rearward laterally disposed spring assembly is provided having outer ends removably received within associated sheaths attached to maxillary molars. A centrally disposed adjustment assembly extends between the anchoring base and the spring assembly for applying a force to the spring assembly which is transmitted to the molars to be distalized.
