Abstract: A mold is for thermoforming a dental appliance. The mold includes a first section of the mold and a second section of the mold. The second section includes a feature having a complex shape, an undercut, or a bite edge. The mold further includes a weakened region that joins the first section to the second section. The weakened region is breakable, deflectable, or deformable in response to a first threshold force to enable the first section and the second section to be removed from the dental appliance after the dental appliance is formed over the mold. The first threshold force is less than a second threshold force that would damage or permanently deform the dental appliance.

Abstract: A support is coupled to an appliance to decrease warpage. The support may comprise a plurality of extensions coupled to the appliance to decrease warpage. The extensions can be coupled to the appliance at one or more of many locations, such as on an occlusal surface, a wall, an edge or an interior of the appliance. In some embodiments, the extensions are coupled to walls of the appliance such as a buccal wall and a lingual wall, and the extensions can be coupled to the walls of the appliance near edges of the walls, such as a gingivally facing edges of the walls that are oriented toward the gingiva when the appliance is worn.

Abstract: An orthodontic aligner includes a first plastic segment having a first shape that fits over a first portion of a dental arch of a patient, a second plastic segment having a second shape that fits over a second portion of the dental arch of the patient, and a connector that joins the first plastic segment to the second plastic segment. The connector is configured to be disposed along a lingual side of one or more additional teeth of the patient without exerting a clinically significant force on the one or more additional teeth. The connector spans a gap between the first plastic segment and the second plastic segment, the gap corresponding to the one or more additional teeth that are not to receive the clinically significant force. The connector includes a flexible material that will perform at least one of flex, move or change shape responsive to applied forces.

Abstract: Systems, methods, and devices for post-processing additively manufactured objects are disclosed herein. In some embodiments, a method includes receiving a plurality of additively manufactured objects having excess material thereon. The method can include removing the excess material from the plurality of additively manufactured objects by rotating the plurality of additively manufactured objects. The method can also include adjusting an environmental temperature while rotating the plurality of additively manufactured objects according to a dynamic temperature profile that facilitates removal of the excess material from the plurality of additively manufactured objects. The dynamic temperature profile can include (a) a first temperature configured to decrease a viscosity of the excess material, and (b) a second temperature configured to increase a stiffness of the plurality of additively manufactured objects.

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: A breakable or deflectable mold includes a first section, a second section, and a weakened region that joins the first section to the second section. The weakened region is breakable or deflectable to enable the first section to be removed independently of the second section after a shell is formed over the breakable mold.
