Abstract
A removable orthodontic appliance that includes an upper plate and a lower plate, the plates being unattached to each other but contacting each other on portions of their surfaces called indexing planes, which are oriented vertically. The tendency of the lower jaw to retract is opposed by the indexing planes of the upper plate which are located on the molars. The indexing planes of the upper plate bear against the indexing planes of the lower plate and thereby maintain the jaw in a jutting-forward position while not interfering with the opening and closing of the jaw that is necessary for normal eating, speaking and sleeping. The appliance of the present invention can be worn 24 hours a day by the patient and operates continuously while in place to maintain the condyles in desired positions.
