Abstract: A method includes forming a plastic orthodontic aligner having a plurality of cavities shaped to receive at least portions of a plurality of teeth of a patient. A first segment of the plastic orthodontic aligner corresponds to a first subset of the plurality of cavities for moving a first subset of the plurality of teeth of the patient. A second segment of the plastic orthodontic aligner corresponds to a second subset of the plurality of cavities. The method further includes removing a first portion of the plastic orthodontic aligner between the first and second segments of the plastic orthodontic aligner to form a connector to minimize force transmission between the first and second segments. The connector is configured to be disposed along one or more additional teeth to span a gap between the first and second segments without exerting a clinically significant force on the one or more additional teeth.

Abstract: The present disclosure provides methods, computing device readable medium, devices, and systems having a dental attachment formation structures. One dental appliance includes a body having a first surface shaped to abut an exterior surface of a tooth and a well portion of the first surface shaped to form an attachment that is to be attached to the exterior surface of the tooth, a release layer formed over a surface of the well to allow the attachment to be removed from the well, and an attachment material that is used to form the attachment positioned within the well.

Abstract: Systems, methods, and devices for producing orthodontic appliances are provided. In one aspect, an orthodontic appliance comprises an outer shell comprising a plurality of cavities shaped to receive the patient's teeth and generate one or more of a force or a torque in response to the appliance being worn on the patient's teeth. The orthodontic appliance can comprise an inner structure having a stiffness different than a stiffness of the outer shell. The inner structure can be positioned on an inner surface of the outer shell in order to distribute the one or more of a force or a torque to at least one tooth received within the plurality of cavities.
