    Abstract: Systems for orthodontic treatments are provided. In some embodiments, a system includes an attachment configured to be coupled to a tooth of a patient, the attachment having a first elasticity. The system can also include an orthodontic appliance having a shell with a plurality of teeth-receiving cavities shaped to reposition the patient's teeth from a first arrangement toward a second arrangement. The shell can have a second elasticity less than the first elasticity. The orthodontic appliance can include an attachment-receiving well formed in the shell. When the orthodontic appliance is worn on the patient's teeth, the attachment-receiving well can engage the attachment to effect a movement of at least one tooth of the patient.

    Abstract: Methods for designing orthodontic appliances are provided. In some embodiments, a method includes receiving a treatment plan for a patient's dentition and generating an aligner model representing an aligner configured to implement a treatment stage of the treatment plan. The aligner model can include a thickness map having a thickness parameter for each location of the aligner model. The method can include adjusting the thickness map by using the aligner model to evaluate an outcome when the aligner is applied to the patient's dentition, and iteratively reducing the value of each thickness parameter of the thickness map based on the evaluation until a resulting thickness is determined for each thickness parameter. The method can also include providing instructions to manufacture the aligner based on the aligner model with the resulting thickness for each thickness parameter of the thickness map.

    Abstract: Patterned dental positioning appliances including a shell including one or more cavities shaped to receive and exert repositioning forces on one or more teeth of a subject's dentition. An inner surface of at least a portion of the one or more cavities may include a raised mesh pattern arranged to contact one or more teeth within the at least a portion of the one or more cavities. The raised mesh pattern may be arranged to impart a contact force that affects one or more of a direction, a duration and a magnitude of the repositioning forces exerted on the one or more teeth. The raised mesh pattern may be is integrally formed with the shell and is made of the same polymer material as the shell.

    Abstract: Systems and methods for processing additively manufactured objects are described herein. In some embodiments, for example, a system includes a controller configured to provide one or more control signals; a heater coupled to the controller, where the heater comprises one or more heating elements arranged to heat a blasting medium in response to the one or more control signals; a chamber coupled to the controller, where the chamber comprises an agitatable drum shaped to receive a plurality of additively manufactured objects, and to agitate the plurality of additively manufactured objects in response to the one or more control signals; and an applicator coupled to the controller, where the applicator comprises a nozzle operative to direct, in response to the one or more control signals, a plurality of thermally conductive particles in the blasting medium toward the plurality of additively manufactured objects within the agitatable drum.
