Abstract: Methods and apparatuses for dental caries detection and communication. These methods and apparatuses may be used in real time, as part of an intraoral scanning system, or at any point following intraoral scanning. These methods and apparatuses may use a plurality of different images of the teeth, each having two or more fields (e.g., wavelengths such as visible light, near-infrared, fluorescent, etc.), and may use a trained pattern matching agent to detect possible caries centers from each image, then may project some or all of the possible caries centers onto a 3D model of the teeth to identify consensus caries and caries centers.

Abstract: Systems and methods for tracking orthodontic treatment using camera images. One or more input two-dimensional (2D) images of a patient's current teeth taken by a camera device can be received. The input 2D image(s) can correspond to occlusal view(s) of the patient's current teeth of the patient's upper and/or lower jaw in a current configuration. One or more rendered 2D images representing target positions of the patient's teeth at a planned treatment stage can be assessed. The rendered 2D image(s) can be based on virtual camera parameters that correspond to the input 2D image(s). One or more rotational differences between the patient's current teeth and the planned treatment stage can be determined by comparing silhouettes of corresponding teeth of the input 2D image(s) to the rendered 2D image(s). A difference indicator indicating the rotational difference(s) can be output.

Abstract: Provided herein are devices and methods generating a panoramic rendering of a subject's teeth. Methods and processes are provided to image the subject's teeth with a dental scan. Methods and processes are also provided to automatically 3D render the subject's teeth with the scan images. Methods and apparatuses are also provided to generate simulated panoramic views of the subject's dentition from various perspectives.

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: Provided herein are systems and methods for monitoring a subject's teeth during orthodontic treatment. A wide angle (e.g., fisheye) image showing an occlusal view of both arches of the subject's dentition and may be input into a monitoring system configured compare the image to the treatment plan to determine how closely the current position of the subject's teeth tracks with the expected or desired positions according to the orthodontic treatment plan.
