Abstract: A system includes an intraoral scanner and a computing device. The intraoral scanner generates an intraoral scan of a dental site. The computing device processes an input comprising data from the intraoral scan using a trained machine learning model that has been trained to classify regions of dental sites, wherein the trained machine learning model generates an output comprising, for each point in the intraoral scan, an indication as to whether the point belongs to a first dental class that represents excess material. The computing device determines, based on the output, one or more points in the intraoral scan that are classified as excess material. The computing device then hides or removes, from at least one of the intraoral scan or a virtual three-dimensional (3D) model generated using the intraoral scan, data for the one or more points that are classified as excess material.

Abstract: A method includes processing an input comprising data from an intraoral image using a trained machine learning model that has been trained to classify regions of dental sites, wherein the trained machine learning model outputs a probability map comprising, for each pixel in the intraoral image, a first probability that the pixel belongs to a first dental class and a second probability that the pixel belongs to a second dental class, wherein the first dental class represents excess material, the excess material comprising material other than teeth or gums. The method further includes determining, based on the probability map, one or more pixels in the intraoral image that are classified as excess material. The method further includes hiding or removing from the intraoral image data for the one or more pixels that are classified as excess material.

Abstract: An adhesive object for placement in a patients mouth includes a body with an upper surface and a lower surface, the body having a shape. A lower surface of the body includes an adhesive. An upper surface of the body includes a feature that may be detectable by an intraoral scanner, wherein at least one of the shape of the body or the feature on the upper surface provides a geometrical reference point for image registration of images generated by the intraoral scanner.

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: 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.
