Abstract: An intraoral scanning system comprises an intraoral scanner and a computing device. The intraoral scanner is to configured to generate intraoral scan data of a bite of a patient. The computing device is configured to receive the intraoral scan data of the bite of the patient during scanning of the bite of the patient, wherein each datum of the intraoral scan data shows a portion of a lower dental arch and a portion of an upper dental arch of the patient. The computing device determines a difference in a relative position of the lower dental arch to the upper dental arch between at least a first datum of the intraoral scan data and a second datum of the intraoral scan data and performs a remedial action responsive to determining that the difference in the relative position of the lower dental arch to the upper dental arch exceeds a difference threshold.

Abstract: An apparatus for intraoral scanning comprises an elongate wand comprising a probe at a distal end of the wand, one or more cameras and a computer processor. The one or more cameras are disposed within the probe and arranged within the probe such that the one or more cameras receive rays of light from an intraoral cavity in a non-central manner, wherein the non-central manner in which the one or more cameras receive the rays of light from the intraoral cavity introduces image distortion. The computer processor is configured to generate a three-dimensional model of an intraoral surface based on images from the one or more cameras, wherein the computer processor compensates for the image distortion specifically introduced by the non-central manner in which the one or more cameras receive the rays of light from the intraoral cavity.

Abstract: Systems, methods, and/or computer-readable media described herein provide technical solutions to aid in the color matching of dental restorations. These systems, methods and/or computer readable media may receive a three-dimensional (3D) model of a tooth, where the 3D model includes a plurality of voxels, set each voxel to a starting optical property, and form a 3D visible light model from the 3D model by iteratively adjusting the optical property of each voxel based on optical properties measured from a scan of the tooth, where the 3D visible light model provides information to generate a color matched dental restoration.

Abstract: A dental scanning system comprises an intraoral scanner and one or more processors. The intraoral scanner comprises one or more light projectors configured to project a pattern (comprising a plurality of pattern features) on a dental object, and two or more cameras configured to acquire sets of images, each comprising at least one image from each camera. The processor(s) are configured to determine a correspondence between pattern features in the pattern of light and image features in each set of images by determining intersections of projector rays corresponding to one or more of the plurality of pattern features and camera rays corresponding to the one or more image features in three-dimensional (3D) space based on calibration data that associates the camera rays corresponding to pixels on the camera sensor of each of the two or more cameras to the projector rays.
