摘要： A method may include generating a 2D blank that can form a 3D dental aligner via thermoforming. The 2D blank may include a first material that includes a first discontinuity. The 2D blank may include a second material integrally formed within the first discontinuity. The first material may have a higher stiffness than the second material. The method may include thermoforming the 2D blank to form the 3D dental aligner having variable stiffness.

摘要： A method to generate a photo realistic dentition image includes receiving a 2D image of a patient dentition including a plurality of patient teeth. The method includes obtaining a template dentition including a plurality of template teeth that correspond with a subset of the patient teeth. The method includes generating a tooth location input to position the plurality of template teeth relative to the subset of the plurality of patient teeth. The method includes identifying an area of generation in the 2D image including a plurality of pixels and contextual information. The method includes generating new photo realistic teeth based on the tooth location input, the contextual information, and the area of generation. The method includes disposing the photo realistic teeth in the 2D image.

摘要： Systems and methods for determining movement of teeth include receiving a first 3D representation of a dentition comprising a plurality of teeth of a patient in an initial position, the 3D representation comprising a plurality of tooth representations including a plurality of points representing surfaces of a respective tooth of the dentition, generating, for each tooth representation, a compressed tooth representation using a geometric encoder model trained to compress the 3D representation of the detention, determining tooth movements of the plurality of teeth of the dentition from the initial position to a final position by applying each compressed tooth representation to a final position model trained to output movement of teeth of a dentition from initial positions to final positions, generating another 3D representation of the dentition comprising the plurality of teeth of the patient in the final position based on applying the tooth movements to the first 3D representations.

摘要： A system includes an orientation determination system comprising a camera where the camera is configured to capture an image of an orientation feature of a physical dental model of a dental arch of a customer with material thermoformed thereon. The orientation determination system is configured to identify an offset of the physical dental model with respect to a fixture plate during positioning or before or after the physical dental model is positioned on the fixture plate by determining an actual orientation of the physical dental model based on the orientation feature. The system also includes a laser trimming system configured to cut the material along a trim line based on the identified offset while the fixture plate is moved about at least two axes to produce a dental aligner specific to the customer and being configured to reposition one or more teeth of the customer.

摘要： A method comprises providing an imaging system configured to acquire images of an intraoral cavity of a user where the imaging system is configured to be operable by the user by allowing the user to visually monitor the intraoral cavity while the images of the intraoral cavity are acquired. The imaging system comprises an image acquisition device configured to acquire the images, and an orientation element configured to orient the image acquisition device with respect to the intraoral cavity to facilitate acquisition of the images. The method further includes at least one of determining an oral condition of the user based on the acquired images or providing feedback based on the acquired images.

摘要： Systems and methods for conducting intraoral scans of a mouth of a user include conducting, using an intraoral scanner at an intraoral scanning site, an intraoral scan of a mouth of a user based on determining that one or more teeth of the user are not being repositioned according to an initial treatment plan designed to reposition the one or more teeth of the user using a first plurality of aligners. The intraoral scan generates three-dimensional data of the mouth of the user. A corrective treatment plan is generated by a treatment plan computing system based on the three-dimensional data. A second plurality of aligners are produced at a fabrication site based on the corrective treatment plan. The second plurality of aligners are specific to the user and configured to reposition the teeth of the user according to the corrective treatment plan.
