Abstract: A system and method for repositioning teeth in a patient jaw includes an attachment bonded to a tooth. The attachment has at least one force receiving component for receiving a force. A polymeric shell repositioning appliance is positioned over at least some of the teeth in the patient jaw. The polymeric shell has at least one force transmitting component for engaging the force receiving component to form a locus of engagement. The locus of engagement transmits the force and moves but is maintained as the tooth is repositioned. In specific embodiments the locus of engagement is maintained over a substantial range of motion. The force transmitted at the locus of engagement increases in response to the tooth lagging an intended position. A space between the positioned appliance and the tooth permits the tooth to move into an intended position.

Abstract: Traditional orthodontic treatment often involves the use of basic repositioning devices, such as braces, and the use of supplementary devices, components or accessories to achieve desired end results. Such components may be mounted on fixed, non-removable devices or they may be part of a removable appliance typically worn prior to the application of the fixed devices. As with traditional treatment, it may be desired to utilize similar components when repositioning teeth with removable elastic repositioning appliances. Due to the nature of elastic appliances, such components may take a variety of forms ranging from readily available traditional accessories to specially created devices. Thus, traditional components may be mounted on or embedded in an elastic appliance, or the appliance may be formed to provide similar components. Likewise, the appliance may be modified to provide additional features for specific orthodontic treatments.
