Abstract: An orthodontic appliance for positioning one or more anterior teeth in a jaw of a patient comprising a clear labial component which extends over the labial surfaces of the patient's teeth and which has an anterior portion and a pair of posterior portions on opposite sides of the dental arch. The anterior and posterior portions of the labial component are in direct contact with the exterior surfaces of the teeth so that no other components of the appliance are located between the anterior and posterior portions of the labial component and those exterior surfaces of the teeth. A lingual component is located within the patient's dental arch for supporting the appliance and for applying force to the patient's anterior teeth, the lingual component operating to move the anterior teeth against the anterior portion of the labial component which serves as a reference against which the teeth are positioned.

Abstract: A facebow which overcomes the adverse effects and limitations of current designs by rotating the maxilla in a downward and forward direction, which assists in correcting anterior open bites. This is accomplished by a design that produces forces above the center of resistance of the maxilla and parallel to the Frankfurt horizontal plane. The extra-oral headgear design is characterized by providing two independent adjustments (forehead width and horizontal/vertical dimensions) that allow the appliance to be customized to each patient. In particular, the two independent adjustments are provided by a fully adjustable forehead pad and bilateral adjustable blocks on opposite sides of the facebow extra-oral frame to provide horizontal and vertical adjustments.
