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*mmand an elastic modulus no greater than about 1.5 GPa; and a second shell with a bending stiffness factor greater than 0.1 GPa*mm.

Aspects of the present disclosure relate to an orthodontic appliance removal device that includes a shaft defining a longitudinal dimension. The shaft includes a shaft proximate end and a shaft distal end, and a lateral portion proximate to the shaft distal end extending transversely away from the shaft in a direction generally orthogonal to the longitudinal dimension. The lateral portion includes a lateral portion proximate end that is adjacent to the shaft distal end, and a lateral portion distal end configured to contact an orthodontic appliance. A handle section is also coupled to the shaft adjacent to the shaft proximate end. In another embodiment, the orthodontic appliance removal device is a multi-tool device which further comprises a seating device for seating an orthodontic appliance and/or a toothbrush.
