Abstract: Methods for designing orthodontic appliances for repositioning a patient's teeth are provided. In some embodiments, a method includes determining a movement path to move one or more teeth from an initial arrangement to a target arrangement, determining a force system to produce movement of the one or more teeth along the movement path, and determining an appliance geometry for an orthodontic appliance configured to produce the force system. The orthodontic appliance can include an outer shell comprising a plurality of teeth-receiving cavities and an inner structure positioned on an inner surface of the outer shell. The inner structure can have an elastic modulus different than an elastic modulus of the outer shell. The method can also include generating instructions for directly fabricating the orthodontic appliance using a layer-by-layer additive manufacturing technique.

Abstract: A multilayer sheet comprising first and second layers is provided. The first layer consists of a co-polyester. The second layer consists of a thermoplastic polyurethane elastomer having an elongation at break of greater than 200%, a hardness of 60A to 85D, an ultimate tensile strength of greater than about 5000 psi, and a light transmission between 400 nm and 800 nm of greater than about 75%. A mold is provided and the multilayer sheet is thermoformed over the mold to form a plurality of tooth-receiving cavities configured to receive and reposition a patient's teeth from a first arrangement toward a second arrangement. Excess material is trimmed from the thermoformed multilayer sheet to form a multilayer dental aligner.

Abstract: A dental appliance having an integrally formed reservoir and/or an ornamental design integrated thereon. The ornamental design can be selected or customized by a patient. The design can be created by directing energy to the dental appliance to alter a material property of at least a portion of the appliance to create the design. Alternatively, a groove or recess can be formed on a surface of the appliance to either mechanically retain an ornamental design or the groove or recess can be filled with ink to form the design. The appliance, including the integrally formed reservoir, can be formed using direct fabrication techniques.

Abstract: A dental appliance for positioning a patient's teeth includes a removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to directly receive at least some of the patient's teeth and apply a resilient positioning force to the patient's teeth. The appliance includes a hard polymer layer having a hard polymer layer elastic modulus disposed between a first soft polymer layer having a first soft polymer layer elastic modulus and a second soft polymer layer having a second soft polymer layer elastic modulus. The hard polymer layer elastic modulus is greater than each of the first soft polymer layer elastic modulus and the second soft polymer layer elastic modulus. At least one of the first soft polymer layer and the second soft polymer layer has a flexural modulus of greater than about 35,000 psi.
