    Abstract: A scan model that is a mathematical model to simulate an imaging process performed by an x-ray imaging device that created a two-dimensional x-ray image of at least one tooth is generated. The scan model uses an initial estimate of one or more parameters of the x-ray imaging device. The one or more parameters include a scan angle parameter indicative of a scan angle of the x-ray imaging device. A two-dimensional contour of a three-dimensional model is adjusted to cause a first component of the two-dimensional contour to approximately align with a second component of the two-dimensional x-ray image. The scan model is calibrated based on data obtained from adjusting the two-dimensional contour.

    Abstract: Methods for fabricating layered appliances are provided. In some embodiments, a method includes generating a digital model of a polymeric shell including a plurality of tooth-receiving cavities shaped to receive and reposition a patient's teeth from a first arrangement toward a second arrangement. The polymeric shell can include an interior layer having a first stiffness, and an exterior layer having a second stiffness greater than the first stiffness. The exterior layer can include a discontinuity formed therein. The method can further include transmitting the digital model to a fabrication system configured to fabricate the polymeric shell based on the digital model.

    Abstract: The present invention provides protective repositioning appliances, accommodating mouth guards, and covering guards that protect an orthodontic patient against impact-induced injuries, as well as related systems and methods. A protective appliance can include teeth receiving cavities shaped to receive and reposition a patient's teeth and can include an occlusal portion having an impact-absorbing compliance. An accommodating mouth guard can include teeth receiving cavities shaped to accommodate a patient's teeth from a first arrangement to a second arrangement and can include an occlusal portion having an impact-absorbing compliance. A covering guard can include a guard segment that covers at least a portion of an appliance. The combination of a guard segment and an appliance can provide an occlusal compliance that absorbs impacts.

    Abstract: The present technology provides solutions for anonymizing patient data and in particular, for anonymizing potentially unique patient-identifying information while retaining clinically relevant information, for example, that can be used to illustrate the results or outcomes of a clinical intervention. In some aspects, a process of the disclosed technology can include steps for receiving patient data, wherein the patient data comprises a patient image corresponding with a patient, receiving treatment data, wherein the treatment data is based on a treatment goal for the patient, automatically determining, using one or more semantic controls, one or more anonymization parameters for the patient image; and generating, based on the one or more anonymization parameters, an anonymized patient image. Systems and machine-readable media are also provided.

    Abstract: A processing device receives intraoral scan data comprising a plurality of intraoral images of a dental site generated during scanning of the dental site by an intraoral scanner, one or more ink markings or other non-rigid indicia having been applied to the dental site prior to the scanning of the dental site, wherein at least two intraoral images of the plurality of intraoral images comprise representations of the one or more ink markings or other non-rigid indica. The processing device performs registration between the plurality of intraoral images and generates a three-dimensional (3D) model of the dental site using the plurality of intraoral images that have undergone registration, the 3D model of the dental site comprising a representation of the one or more ink markings or other non-rigid indica that were applied to the dental site prior to the scanning of the dental site.
