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 for intraoral scanning includes an elongate handheld wand comprising a probe at a distal end of the handheld wand, one or more light projectors coupled to the handheld wand, and one or more cameras coupled to the handheld wand. Each camera comprises a camera sensor and objective optics comprising one or more lenses. Each camera is configured to focus at an object focal plane that is located between 1 mm and 30 mm from the lens that is farthest from the camera sensor. The apparatus further includes a fluorescent transparent film deposited on a surface selected from the group consisting of: a window of the probe through which light exits and enters the probe, and a transparent surface that is not integral to the probe.

Abstract: Methods and apparatuses for generating and displaying 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). These methods and apparatuses may be used for identifying and evaluating lesions, caries and cracks in the teeth.

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.
