Abstract: The present disclosure provides computing device implemented methods, computing device readable media, and systems for motion compensation in a three dimensional scan. Motion compensation can include receiving three-dimensional (3D) scans of a dentition, estimating a motion trajectory from one scan to another, and calculating a corrected scan by compensating for the motion trajectory. Estimating the motion trajectory can include one or more of: registering a scan to another scan and determining whether an amount of movement between the scans is within a registration threshold; determining an optical flow based on local motion between consecutive two-dimensional (2D) images taken during the scan, estimating and improving a motion trajectory of a point in the scan using the optical flow; and estimating an amount of motion of a 3D scanner during the scan as a rigid body transformation based on input from a position tracking device.

Abstract: A processing device of a system makes a comparison between a current image of an oral cavity of a patient and one or more previously received images of the oral cavity of the patient, the current image and the one or more previously received images having been generated by an intraoral scanner. The processing device determines an amount of overlap between a current field of view of the intraoral scanner and topography scans of the oral cavity based on the comparison. The processing device outputs a warning indicator associated with a positioning of the current field of view of the intraoral scanner responsive to determining that the amount of overlap fails to meet or exceed an overlap threshold.

Abstract: A system includes an intraoral scanner configured to generate intraoral scan data comprising intraoral images of an arch of a patient, and a computing device operatively coupled to the intraoral scanner. The computing device is configured to receive the intraoral scan data comprising the intraoral images of the arch generated during scanning of the arch by the intraoral scanner, a plurality of objects each comprising a surface pattern having been applied onto the arch of the patient prior to the scanning of the arch, wherein at least some of the intraoral images comprise representations of one or more objects of the plurality of objects. The computing device is further configured to generate a three-dimensional (3D) model of the arch using the intraoral images that comprise representations of the one or more objects and output the 3D model to a display.

Abstract: Methods and apparatuses (including systems and devices), including computer-implemented methods for segmenting, correcting and/or modifying a three-dimensional (3D) model of a subject's oral cavity to determine individual components such as teeth, gingiva, tongue, palate, etc., that may be selective and/or collectively digitally manipulated. In some implementations, artificial intelligence uses libraries of labeled 2D images and 3D dental models to learn how to segment a 3D dental model of a subject's oral cavity using 2D images, height map and/or other data and projection values that relate the 2D images to the 3D model. As noted herein, the dental classes can include a variety of intra-oral and extra-oral objects and can be represented as binary values, discrete values, a continuum of height map data, etc. In some implementations, several dental classes are predicted concurrently.

Abstract: A system comprises an image capture device, an augmented reality (AR) display to display, and a processing device. The processing deice receives image data of a dental arch from the image capture device and processes the image data using a plurality of detection rules, where each detection rule detects one or more dental conditions. The processing device determines a dental condition for the dental arch based on the processing, determines a position of an area of interest on the dental arch, wherein the area of interest is associated with the dental condition, generates a visual overlay comprising an indication of the dental condition at the position of the area of interest, and outputs the visual overlay to the AR display, wherein the visual overlay is superimposed over a view of the dental arch on the AR display at the position of the area of interest.

Abstract: A first computing device receives a command to associate the first computing device with an intraoral scanner, the command comprising an identifier. The first computing device wirelessly connects with a second computing device, and sends the identifier to the second computing device. The second computing device wirelessly connects to the intraoral scanner and associates the first computing device with the intraoral scanner. Subsequently, intraoral scan data generated by the first intraoral scanner is sent to the second computing device, the intraoral scan data is processed by the second computing device to generate a three-dimensional surface of a dental site, the three-dimensional surface or a view of the three-dimensional surface of the dental site is sent to the first computing device, and the three-dimensional surface or the view of the three-dimensional surface of the dental site is displayed by the first computing device.

Abstract: Calibrating an intraoral scanner includes obtaining reference data of a reference three-dimensional (3D) representation of a calibration object and obtaining, based on the intraoral scanner being used by a user to scan the 3D calibration object, and from one or more device to real-world coordinate transformations of two-dimensional (2D) images of the 3D calibration object, measurement data. Calibrating the intraoral scanner further includes aligning the measurement data to the reference data to obtain alignment data and updating, based on the alignment data, said one or more transformations.
