    Abstract: A processing device receives images of an oral cavity of a patient generated by an intraoral scanner and subsequently receives an additional image of the oral cavity of the patient. The processing device makes a comparison between the additional image and the previously received images and determines an amount of overlap between the additional image and at least one of the previously received images based on the comparison. The processing device displays image data from at least one of a) the images or b) the additional image. The processing device determines whether or not the amount of overlap meets or exceeds an overlap threshold, and displays one or more visual indicators based on whether or not the amount of overlap meets or exceeds the overlap threshold, wherein the one or more visual indicators indicate whether or not the amount of overlap meets or exceeds the overlap threshold.

    Abstract: A method comprises obtaining reference data about a 3D calibration object, the reference data comprising known coordinates for a plurality of points on the object, and obtaining measurement data comprising measurements for the plurality of points on the object, the measurement data having been generated based on scanning of the object by an uncalibrated intraoral scanner. The method comprises comparing the measurement data to the reference data to determine differences therebetween and applying the determined differences between the measurement data and the reference data for the plurality of points to a function to generate a compensation model that compensates for one or more inaccuracies of the intraoral scanner. The compensation model is then stored, wherein the compensation model causes the intraoral scanner to be a calibrated intraoral scanner and is usable to correct measurement errors of the intraoral scanner caused by the one or more inaccuracies of the intraoral scanner.

    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.
