A functional orthodontic appliance which includes permanent magnets embedded in the upper and lower acrylic positioning parts normally positioned behind the incisor teeth of the patient. The magnets are of opposite polarity on the top and bottom parts and positioned so as to influence movement of the patient's mandible into a vertical bite plane. The appliance may also include positioning wires and springs for promoting back tooth eruption corresponding to the change in the bite plane, and lateral expansion screws to promote mouth arch expansion.
