Abstract: A system for repositioning teeth a patient from an initial tooth arrangement to a final tooth arrangement includes a plurality of incremental position adjustment appliances, each having an arrangement of cavities shaped to receive and reposition teeth of the patient. The cavities in at least one appliance in the system have a different geometry than that of at least one other appliance in the system. At least some of the appliances in the system are successively worn by the patient to exert force on at least one tooth and move the teeth of the patient from a first arrangement to a successive arrangement different from the first arrangement. The system includes a first multilayer shell with a bending stiffness factor less than about 0.1 GPa*mm3 and an elastic modulus no greater than about 1.5 GPa; and a second shell with a bending stiffness factor greater than 0.1 GPa*mm3.
