ABSTRACT:
A computer-implemented method treats teeth by generating a digital arrangement of teeth; specifying a sequence of tooth movements to move the teeth to a target arrangement; and generating one or more appliances in accordance with the specified sequence of tooth movements, the appliances comprise polymeric shells having cavities and wherein the cavities of successive shells have different geometries shaped to receive and resiliently reposition teeth from one arrangement to a successive arrangement.
