Abstract: An orthodontic alignment device can have a palatal contour anchorage (PCA) feature that generally matches the shape of the patient's hard pallet. This PCA feature may be built slightly off-set to deliberately push against the patient's palate and/or gingiva to provide anchorage support of staged translation of the teeth. By transferring the required anchorage away from the teeth and onto the palate, through the PCA feature, the adjacent teeth are no longer subjected to unwanted side effects of reaction forces.

Abstract: The present disclosure provides method, computing device readable medium, and devices for dental appliances with repositioning jaw elements. An example of a method can include identifying a misaligned jaw of a patient from a virtual image of the patient's jaw, providing a treatment plan for the patient including a virtual model of a dental appliance having a first shell and a second shell configured to reposition at least one tooth of the patient, and adjusting the position of the repositioning jaw elements on the first shell and the second shell to comply with a number of constraints. The virtual model of the dental appliance including repositioning jaw elements on the first shell and the second shell configured to move a position of the misaligned jaw of the patient.

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.

Abstract: A set of stabilizer aligners includes an upper stabilizer aligner for an upper dental arch of a patient and a lower stabilizer aligner for a lower dental arch of the patient. The upper stabilizer aligner comprises a first set of cavities that conform to a dentition of the upper dental arch and a first set of stabilizing features. The lower stabilizer aligner comprises a second set of cavities that conform to a dentition of the lower dental arch and a second set of stabilizing features. Stabilizing features in the second set of stabilizing features are configured to contact opposing stabilizing features in the first set of stabilizing features. The upper stabilizer aligner and the lower stabilizer aligner prevent jaw movement of the patient while the upper stabilizer aligner is worn on the upper dental arch, the lower stabilizer aligner is worn on the lower dental arch, and the upper stabilizer aligner is engaged with the lower stabilizer aligner.
