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: In embodiments, a first 3D model of a patient's teeth based on first intraoral scan data taken at a first time is processed to recognize the teeth in the first 3D model. A second 3D model of the patient's teeth based on second intraoral scan data taken at a second time is processed to recognize the teeth in the second 3D model. The first 3D model is compared to the second 3D model and a plurality of AOIs in the second virtual 3D model representative of at least one of tooth wear, tooth breakage, tooth movement, gingival recession or gingival swelling are determined based on the comparison. The teeth recognized in the first 3D model are compared to the teeth recognized in the second 3D model, and one or more AOIs in the second virtual 3D model representative of tooth wear or tooth breakage are determined based on the comparison.

Abstract: Data from an intraoral scan is received, the data comprising a plurality of intraoral images of a dental site. At least two intraoral images are identified that comprise a representation of at least a portion of a non-rigid object that was affixed to the dental site at a target area. Image registration is performed between the at least two intraoral images using the non-rigid object identified in the at least two intraoral images. A 3D model of the dental site is generated based on the image registration. A representation of the non-rigid object is subtracted from the 3D model based on the known properties of the non-rigid object. A surface of a portion of the dental site is interpolated where the non-rigid object was located based on a) data for other portions of the dental site and b) the surface of the base of the non-rigid object.

Abstract: Systems and methods are provided for preparation of orthodontics and prosthodontics. A method may include scanning a patient's teeth to form first 3D data of the patient's teeth including a removable element that obscures part of the dental surfaces of the patient's teeth and non-obscured tooth surfaces, removing the removable element form the patient's teeth so that the removable element no longer obscures the part of the dental surfaces of the patient's teeth, and scanning the previously obscured part of the dental surfaces of the patent's teeth and the non-obscured tooth surfaces.

Abstract: A method of using AR for dentistry and orthodontics is provided. An image of a dental arch is received, the image having been generated by an image capture device associated with an augmented reality (AR) display. A processing device registers the image to previous image data associated with the dental arch, compares one or more areas of the dental arch from the image to one or more corresponding areas of the dental arch from the previous image data, determines a position of an area of interest on the dental arch based on the comparing, generates a visual overlay comprising an indication of the area of interest, and outputs the visual overlay to the AR display, wherein the visual overlay is superimposed over a view of the dental arch on the AR display at the position of the area of interest.

Abstract: A method and system are provided for manufacturing a physical dental model. A virtual model is provided representative of at least a portion of the intra-oral cavity including at least one dental implant implanted therein, and the virtual model includes a virtual portion representative of each dental implant. The virtual spatial disposition of each such virtual portion is determined with respect to the virtual model, corresponding to a real spatial disposition of the respective implant with respect to the intra oral cavity. A physical model is then manufactured based on the virtual model, the physical model including a physical analog corresponding to each implant at a respective physical spatial disposition with respect to the physical model corresponding to the respective virtual spatial disposition of the respective virtual portion with respect to the first virtual model as already determined. In some embodiments, a jig is provided configured for maintaining a desired physical spatial disposition between the physical analog and a cavity of the physical dental model at least until the physical analog is affixed in the cavity.
