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: 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.

Abstract: An apparatus (system, device, method, and the like) is disclosed for refining a three-dimensional (3D) model, particularly 3D models of a subject's dentition. An initial 3D model is received or generated along with a plurality of two-dimensional (2D) images corresponding to the 3D model. The 3D model is refined using edge boundaries of a space around or between two or more objects of the 3D model identified from the 2D images.

Abstract: Methods and apparatuses (including systems and devices) for modifying a three-dimensional (3D) model of a subject's oral cavity to determine individual components such as teeth, gingiva, tongue, palate, etc. In some implementations one or more automated machine learning agents may modify one or more subsets of 3D models of the subject's oral cavity using height map data to identify, segment and/or modify to mesh regions of a 3D model constructed from a plurality of 2D images of the subject's dental cavity.

Abstract: Methods and apparatuses (including devices and systems, such as intraoral scanners and software) for analyzing images of a subject's teeth. In some examples these methods may include examining the same teeth or tooth regions across different times and/or different imaging modalities, including but not limited to visible light, infrared, florescent, etc. Also described herein are methods and apparatuses for using a single, master, control for automatically or semi-automatically simultaneously adjusting multiple imaging parameters across multiple images of a region taken with different imaging modalities and/or at different times.

Abstract: Remote progress tracking of orthodontic treatment may include receiving a 3D digital model of a patient's dentition including the patient's teeth. A 3D digital model of an impression of occlusal surfaces of the patient's teeth may be generated. The teeth of the 3D digital model of the patient's dentition may be registered to the position and orientation of the patient's teeth in the 3D digital model of the impression of the occlusal surfaces of the patient's teeth. An updated 3D digital model of the patient's teeth may be generated based on the registration.
