Abstract: A method comprises receiving, by a processing device, clinical data of a first state of one or more dental arches of a patient. The method further comprises determining, by the processing device, one or more stages of an orthodontic treatment plan for correcting the one or more dental arches based on processing of the clinical data. Determining a stage of the orthodontic treatment plan comprises determining one or more actions to be performed with respect to the one or more dental arches and determining a target state of the one or more dental arches that is predicted to result at least in part from the one or more actions.

Abstract: In embodiments, a processing device detects a margin line in a model of a preparation from one or more images. The processing device determines, for each segment of a plurality of segments of the margin line, a quality score for the segment. The processing device determines that a segment of the margin line has a quality score that is below a quality threshold, wherein the segment of the margin line was generated based on a first set of images. Responsive to determining that the segment of the margin line has the quality score that is below the quality threshold, the processing devices updates the three-dimensional model of the preparation by replacing a portion of the three-dimensional model associated with the segment of the margin line with image data from at least one of a new image or a second set of images.

Abstract: An appliance comprises a passive component and an active force generating component, in which the active force generating component is configured to react to a stimulus and generate tooth movement forces. In some embodiments, the passive component is configured to deflect when placed on one or more teeth and generate tooth movement forces, which are combined with tooth movement forces of the force generating component. In some embodiments, the passive component comprises a polymer which is less reactive to the stimulus than the force generating component. The force generating component can be configured to increase force to one or more teeth at an appropriate time.

Abstract: Intraoral systems and methods including aligners having soft tissue sensors. The soft tissue sensors may detect protein biomarkers to determine effectiveness of the aligners for causing tooth movement according to a treatment plan. One or more microneedles may be configured to pass the protein biomarker to the soft tissue sensor. A processor may be configured to compare a detected level of the protein biomarker to an expected lever of the protein biomarker, and determine whether an aligner should be replaced. A bias may be configured to apply continuous force to hold the microneedle(s) against a patient's soft tissue. A controller may be configured to apply a biasing force to move the microneedles(s) from a retracted position to an extended position to penetrate the patient's soft tissue.

Abstract: A method for preparing a tooth crown may include generating a 3D model of an external surface of a patient's tooth and generating a 3D model of an external surface of a first crown based on the 3D model of the external surface of the patient's tooth. The method may also include preparing the patient's tooth to receive the first crown while generating the 3D model of the external surface. A 3D model of the prepared tooth my be generated. A 3D model of an internal surface of the first crown may also be generated. The 3D model of the external surface and the 3D model of the internal surface may form a 3D model of the first crown.

Abstract: A processing device receives a plurality of intraoral scans of a dental arch. The processing device determines, from the plurality of intraoral scans, a first set of intraoral scans that depict a restorative object and a second set of intraoral scans that fail to depict any restorative object. The processing device generates a multi-resolution three-dimensional model of the dental arch, wherein a first portion of the multi-resolution three-dimensional model is generated from the first set of intraoral scans, has a first resolution and represents the restorative object, and wherein a second portion of the multi-resolution three-dimensional model is generated from the second set of intraoral scans, has a second resolution and represents a remainder of the dental arch, wherein the first resolution is greater than the second resolution.

Abstract: In embodiments, a processing device generates a three-dimensional model of a dental site from scan data, the three-dimensional model comprising a representation of a tooth, wherein a portion of the three-dimensional model comprises an interfering surface that obscures a portion of the tooth. The processing device receives or generates an image of the tooth, wherein the image depicts the interfering surface. The processing device processes the image to generate a modified image, wherein the portion of the tooth that was obscured by the interfering surface in the image is shown in the modified image. The processing device updates the three-dimensional model of the dental site by replacing, using the modified image, the portion of the three-dimensional model that comprises the interfering surface that obscures the portion of the tooth, wherein the portion of the tooth that was obscured in the three-dimensional model is shown in an updated three-dimensional model.

Abstract: A method and/or system generates a video of teeth of an individual over time. In one example, images comprising teeth of an individual are received, wherein the images are arranged in a sequence and each image is associated with a different stage of treatment of the teeth. One or more of the images are modified and/or replaced to align the images to one another. One or more synthetic images are generated, wherein each synthetic image is generated based on a pair of sequential images in the sequence and is an intermediate image that comprises an intermediate state of the teeth between a first state of a first image of the pair of sequential images and a second state of a second image of the pair of sequential images. A video is then generated that comprises the images and the one or more synthetic images.
