摘要： A confocal imaging apparatus includes an illumination module to generate an array of light beams. Focusing optics perform confocal focusing of an array of light beams onto a non-flat focal surface and direct the array of light beams toward a three dimensional object to be imaged. A translation mechanism adjusts a location of at least one lens to displace the non-flat focal surface along an imaging axis. A detector measures intensities of an array of returning light beams that are reflected off of the three dimensional object and directed back through the focusing optics. Intensities of the array of returning light beams are measured for locations of the at least one lens for determination of positions on the imaging axis of points of the three dimensional object. Detected positions of one or more points are adjusted to compensate for the non-flat focal surface.

摘要： 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.

摘要： Provided herein are systems and methods for monitoring a subject's teeth during orthodontic treatment. A wide angle (e.g., fisheye) image showing an occlusal view of both arches of the subject's dentition and may be input into a monitoring system configured compare the image to the treatment plan to determine how closely the current position of the subject's teeth tracks with the expected or desired positions according to the orthodontic treatment plan.

摘要： 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.

摘要： Systems, methods, and/or computer-readable media described herein provide technical solutions to the highly technical problems of machine generation of dental restorations. In particular, these systems, methods and/or computer readable media may provide technical solutions to aid in the creation of dental restorations that more closely resemble a natural tooth (including its internal optical structure). These systems, methods and/or computer readable media may help in virtually rendering a tooth, including its internal optical structure, and apply these renderings (e.g., digital models) to the fabrication of the dental restoration.
