Abstract: Apparatuses and methods for monitoring the performance of an orthodontic appliance for repositioning a patient's teeth. An orthodontic appliance may include a plurality of teeth receiving cavities shaped to reposition the patient's teeth from an initial arrangement towards a target arrangement, and one or more sensors configured to determine tooth movement (based on position and/or orientation) and/or forces applied to the teeth. The sensor may be distributed between attachments and aligners that mate with the attachments.

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: Embodiments relate to an aligner breakage solution. A method includes obtaining a digital design of a polymeric aligner for a dental arch of a patient. The polymeric aligner is shaped to apply forces to teeth of the dental arch. The method also includes performing an analysis on the digital design of the polymeric aligner using at least one of a) a trained machine learning model, b) a numerical simulation, c) a geometry evaluator or d) a rules engine. The method may also include determining, based on the analysis, whether the digital design of the polymeric aligner includes probable points of damage, wherein for a probable point of damage there is a threshold probability that breakage, deformation, or warpage will occur. The method may also include, responsive to determining that the digital design of the polymeric aligner comprises probable points of damage, performing corrective actions based on the probable points of damage.

Abstract: Methods and systems for designing dental appliances are provided. In some embodiments, a method includes identifying one or more intended outcomes for one or more areas of a dental appliance, where the dental appliance is shaped to receive and engage with a person's dentition in accordance with a treatment plan; identifying one or more acceptability criteria for evaluating compliance with the one or more intended outcomes; obtaining an appliance model for the dental appliance, where the appliance model represents the one or more areas with one or more first physical properties conforming to the one or more acceptability criteria, and where the one or more first physical properties are different than one or more second physical properties outside the one or more areas; providing three-dimensional (3D) printing instructions to generate the dental appliance using the appliance model; and 3D printing the dental appliance using the 3D printing instructions.
