摘要:
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.
