Abstract: A method of generating a three-dimensional virtual model of an intraoral object includes capturing, by an imaging apparatus for performing intraoral scans, surface scan data of the intraoral object while changing a position of at least one lens of focusing optics of the imaging apparatus, wherein the surface scan data comprises depth data for a plurality of points of the intraoral object. The method further includes adjusting the depth data for one or more of the plurality of points based at least in part on the position of the at least one lens associated with the depth data for the one or more of the plurality of points. The method further includes generating the three-dimensional virtual model of the intraoral object using the adjusted depth data.

Abstract: Methods and apparatuses for generating a model of a subject's teeth. Described herein are intraoral scanning methods and apparatuses for generating a three-dimensional model of a subject's intraoral region (e.g., teeth) including both surface features and internal features. These methods and apparatuses may be used for identifying and evaluating lesions, caries and cracks in the teeth. Any of these methods and apparatuses may use minimum scattering coefficients and/or segmentation to form a volumetric model of the teeth.

Abstract: A computing device comprises a processor that uses a field curvature model that is calibrated to a confocal imaging apparatus. The processor receives intensity measurements generated by pixels of a detector of the confocal imaging apparatus. The processor determines, for each pixel, a focusing setting of the confocal imaging apparatus that provides a maximum measured intensity. The processor determines, for each pixel, a depth of a point of a 3D object associated with the pixel that corresponds to the determined focusing setting. The processor adjusts the depth of at least one point of the 3D object based on applying the determined focusing setting for the pixel associated with the at least one point to the field curvature model to compensate for a non-flat focal surface of the confocal imaging apparatus. The processor determines a shape of the 3D object based at least in part on the adjusted depth.

Abstract: Processing logic makes a comparison between first image data and second image data of a dental arch and determines a plurality of spatial differences between a first representation of the dental arch in the first image data and a second representation of the dental arch in the second image data. The processing logic determines that a first spatial difference is attributable to scanner inaccuracy and that a second spatial difference is attributable to a clinical change to the dental arch. The processing logic generates a third representation of the dental arch that is a modified version of the second representation, wherein the first spatial difference is removed in the third representation, and wherein the third representation comprises a visual enhancement that accentuates the second spatial difference.

Abstract: An intraoral scanning system comprises an elongate handheld wand with a probe at a distal end, a structured light projector configured to project a uniform structured light pattern onto an object, a plurality of cameras configured to capture points of the uniform structured light pattern projected onto the object by the structured light projector, and one or more processors. The one or more processors are configured to determine a correspondence between projected points in the uniform structured light pattern generated by the structured light projector and captured points of the uniform structured light pattern captured by the plurality of cameras viewing the uniform structured light pattern projected onto the object, and to use triangulation and the determined correspondence to determine three-dimensional points in space associated with the captured points of the uniform structured light pattern captured by the plurality of cameras.

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.

Abstract: A system comprises an intraoral scanner and one or more computing devices. The one or more computing devices are configured to: receive a plurality of intraoral scans of the dental arch; determine that an intraoral scan comprises a depiction of a first 3D surface and a depiction of at least a feature of a second 3D surface that is separated from the first 3D surface by at least one intervening 3D surface not shown in the at least one intraoral scan; stitch together the plurality of intraoral scans; and generate a virtual 3D model of the dental arch from the plurality of intraoral scans, wherein a distance between the first 3D surface and the second 3D surface in the virtual 3D model is based on the distance between first 3D surface and the feature of the second 3D surface in the at least one intraoral scan.
