    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: A 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, deflectable, or deformable in response to a first threshold force to enable the first section to be removed from a shell independently of the second section after the shell is formed over the mold. The first threshold force is less than a second threshold force that would damage or permanently deform the shell. The first section is a first mold of at least a portion of one or more first teeth of a dental arch and the second section is a second mold of at least a portion of one or more second teeth of the dental arch.

    Abstract: Systems, methods, and devices for improved orthodontic treatment of a patient's teeth are provided herein. In some aspects, a method for fabricating an orthodontic appliance for treating a patient's teeth is disclosed. The method may comprise determining a movement path to move a tooth from an initial arrangement towards a target arrangement; determining a force system to move the tooth along the movement path; determining a variable gable bend to produce the force system; determining a geometry for a tooth receiving cavity of the appliance based on the variable gable bend; and generating instructions for fabricating the appliance having a tooth receiving cavity formed according to the geometry for the tooth receiving cavity.

    Abstract: A dental attachment placement device comprises a plurality of articulated registration elements shaped for placement on a plurality of teeth, which can facilitate placement, accommodate tooth movement, and improve alignment of the registration elements with the teeth, so as to accurately position an attachment for placement. The plurality of registration elements may comprise one or more attachment supports and one or more retention supports extending from the plurality of registration elements. A dental attachment can be removably coupled to the attachment support. The plurality of registration elements and attachment supports may be located on opposing sides of one or more teeth in order to maintain placement prior to adhering the attachment to the tooth. In some embodiments, each of the plurality of registration elements comprises a tooth registration surface shaped to engage the tooth with a specific position and orientation for accurate positioning of the attachment.
