ABSTRACT:
Systems for moving teeth of a patient's dental arch from a first tooth arrangement to a second tooth arrangement include a plurality of resilient appliances such as positioning trays or elongated arch members that are used in sequence. Each appliance of the systems includes a row of spaced apart couplings for connection to respective teeth of the dental arch. The appliances have certain geometric characteristics that match the geometric characteristics of other appliances of the system, and at least one appliance has a stiffness that is greater than the stiffness of at least one other appliance.
