ABSTRACT:
A generally horseshoe shaped clear flexible resilient plastic wire-imbedded orthodontic appliance is made with a plastic portion with contours on the lingual side and on the labial side, wherein the contours snugly cover the patient's teeth so that the appliance remains in place. One or more flexible wires are imbedded within the lingual side of the plastic portion from the left molar area to the right molar area of the plastic portion, whereby the wires apply force on the lingual side of the patient's bite. The appliance is formed by obtaining a plaster cast of the patient's teeth and gums, removing plaster teeth from the plaster cast of the gums, reattaching the plaster teeth to the plaster cast of the gums to form a cast of proper bite alignment, attaching one or more wires to the labial surface of the aligned plaster teeth so the wires become imbedded within thermosetting plastic placed over the cast, putting the cast in a thermosetting plastic molding machine, inserting thermosetting plastic in the machine, and heating the thermosetting plastic around the cast of the proper bite alignment, so the wires are imbedded within the formed appliance after the thermosetting plastic cools. A series of appliances may be used to shift a patient's bite to proper bite orientation.
