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: Embodiments relate to techniques for selecting images from a plurality of images generated by an intraoral scanner. A method includes receiving a plurality of images of a dental site generated by an intraoral scanner, identifying a subset of images from the plurality of images that satisfy one or more selection criteria, selecting the subset of images that satisfy the one or more selection criteria, and discarding or ignoring a remainder of images of the plurality of images that are not included in the subset of images.

Abstract: An intraoral scanner includes a plurality of cameras configured to generate a set of intraoral images, each intraoral image from the set of intraoral images being associated with a respective camera of the plurality of cameras. A computing device is configured to receive the set of intraoral images; select a first camera of the plurality of cameras that is associated with a first intraoral image of the set of intraoral images that satisfies one or more criteria, and output the first intraoral image associated with the first camera to a display.

Abstract: Systems, methods, and/or computer-readable media described herein provide technical solutions to the highly technical problems of machine generation of dental restorations. In particular, these systems, methods and/or computer readable media may provide technical solutions to aid in the creation of dental restorations that more closely resemble a natural tooth (including its internal optical structure). These systems, methods and/or computer readable media may help in virtually rendering a tooth, including its internal optical structure, and apply these renderings (e.g., digital models) to the fabrication of the dental restoration.

Abstract: Embodiments relate to techniques for real-time and post-scan visualization of intraoral scan data, which may include 3D images, 3D scans, 3D surfaces and/or 3D models. In one embodiment, an intraoral scanning system comprises a plurality of image sensors to periodically generate a set of intraoral two-dimensional (2D) images, wherein for each set of intraoral 2D images each image sensor of the plurality of image sensors is to generate an intraoral 2D image, and wherein relative positions and orientations of the plurality of image sensors are known. The intraoral scanning system further comprises a computing device, wherein the computing device is to perform the following for each set of intraoral 2D images: generate a combined intraoral image based on merging the set of intraoral 2D images together during scanning; and output the combined intraoral image to a display.

Abstract: Methods and apparatuses for taking, using and displaying three-dimensional (3D) volumetric models of a patient's dental arch. A 3D volumetric model may include surface (e.g., color) information as well as information on internal structure, such as near-infrared (near-IR) transparency values for internal structures including enamel and dentin.
