Abstract: Methods and systems are described that mark and/or correct margin lines and/or other features of dental sites. In one example a three-dimensional model of a dental site is generated from intraoral scan data of the dental site, the three-dimensional model comprising a representation of a preparation tooth. An image of the preparation tooth is received or generated. Data from the image is processed using a trained machine learning model that has been trained to identify margin lines of preparation teeth, wherein the trained machine learning model outputs a probability map comprising, for each pixel in the image, a probability that the pixel depicts a margin line. The three-dimensional model of the dental site is then updated by marking the margin line on the representation of the preparation tooth based on the probability map.

Abstract: Methods and systems are described that mark and/or correct margin lines and/or other features of dental sites. In one example a three-dimensional model of a dental site is generated from intraoral scan data of the dental site, the three-dimensional model comprising a representation of a preparation tooth. An image of the preparation tooth is received or generated, the image comprising a height map. Data from the image is processed using a trained machine learning model that has been trained to identify margin lines of preparation teeth, wherein the trained machine learning model outputs a probability map comprising, for each pixel in the image, a probability that the pixel depicts a margin line. The three-dimensional model of the dental site is then updated by marking the margin line on the representation of the preparation tooth based on the probability map.

Abstract: Methods and systems are described that use 2D images and intraoral scans to generate and/or augment 3D models of dental site. In one example a method includes receiving a plurality of intraoral scans of a dental site generated by an intraoral scanner and a plurality of two-dimensional (2D) images of the dental site generated by the intraoral scanner, generating a three-dimensional (3D) surface of the dental site from the plurality of intraoral scans, determining a correspondence between points on the 3D surface and points in one or more 2D images of the plurality of 2D images, and performing one or more operations using the correspondence between the points on the 3D surface and the points on the one or more 2D images.

Abstract: A processing device generates a visual overlay comprising a virtual model of a dental arch that represents a treatment outcome for the dental arch. The processing device outputs the visual overlay to an augmented reality (AR) display or virtual reality (VR) display. The processing device receives user input based on a user interaction with the virtual model of the dental arch, wherein the user input modifies the virtual model of the dental arch and determines an update to the treatment outcome for the dental arch based on a user input. The processing device generates an updated treatment plan based on the update to the treatment outcome and updates the visual overlay, wherein the updated visual overlay comprises a view of the dental arch after the updated treatment outcome.

Abstract: Intraoral scanning systems for displaying 3D models of a patient's dental arch and near-IR images from the dental arch. These systems may include a wand with one or more image sensors and processors for processing the 3D models and near-IR information. The 3D models may include surface (e.g., color) information and the near-IR images may include information on internal structures, including enamel and dentin.
