Augmented reality enhancements for dental practitioners

A processing device receives, from an image capture device associated with an augmented reality (AR) display, a plurality of images of a face of a patient. The processing device selects a subset of the plurality of images that meet one or more image selection criteria. The selection comprises determining, from the plurality of images, a first image that represents a first position extreme for the face; determining, from the plurality of images, a second image that represents a second position extreme of the face; selecting the first image; and selecting the second image. The processing device further generates a model of a jaw of the patient based at least in part on the subset of the plurality of images that have been selected.

In embodiments of a method for visually guided access cavity preparation, the method makes use of a 2D image of a phantom implant matching a desired access cavity path to a pulp chamber of a tooth anatomy, the phantom implant being non-tapered along its length and having a diameter no greater than 1.0 mm. The phantom implant is overlaid over a 2D or 3D image of the tooth anatomy and drilling of the access cavity path is monitored using a visual display that compares the drilled access cavity path to the desired access cavity path.

The present disclosure provides an implant surgery guiding method of guiding a position, direction and depth of a fixture to a dentist by real-time images. The implant surgery guiding method includes: (a) generating a 3D oral cavity image for a patient; (b) designing a target placement including a target position and a target orientation of a fixture based in the 3D oral cavity image; (c) attaching an oral marker comprising a first pattern to a jawbone or a surrounding body portion of the patient, determining a spatial relationship between the oral marker and the jawbone, attaching a handpiece marker comprising a second pattern on a handpiece of a dentist, and determining a spatial relationship between the handpiece marker and the handpiece; and (d) estimating positions and orientations of the jawbone and the handpiece based on changes in positions and orientations of the oral marker and the handpiece marker while tracking the motions of the oral marker and the handpiece marker, and displaying a jawbone image portion and a handpiece image portion on a screen reflecting real-time changes in the positions and orientations of the jawbone and the handpiece.

System For Preparing Teeth For The Placement Of Veneers

Dental instrumentation for use in guiding a cutting tool to remove tooth structure from a working tooth is prepared. A digital model of cutting guide shell structure for placement around a portion of the tooth to be treated is combined with preset tool movements to be made by the cutting tool by one or more processors to define final cutting guide data corresponding to final cutting guide structure for guiding the cutting tool. A digital model of a fixation instrument configuration for fixing the dental instrumentation to an adjacent tooth to the working tooth is combined with the final cutting guide data by one or more processors to define final instrument configuration data corresponding to a final instrument configuration for releasably fixing the dental instrumentation to the adjacent tooth and for guiding the cutting tool in the removal of the tooth structure from the tooth to be treated.

SURGICAL GUIDES
20220015861 · 2022-01-20 ·

Disclosed herein are surgical guides, surgical supports, surgical systems, and methods of use thereof. The surgical guides, supports, and systems discloses herein can include an instrument and a patient-specific support. The instrument can be connectable to a surgical support arm and include a guide surface. The patient-specific support can comprise an instrument engagement portion and an anatomy contacting surface. The instrument engagement portion can be configured to receive a portion of the instrument and the anatomy contacting surface contoured to match a contour of an anatomical surface of a patient. When coupled to the patient-specific support, the surgical support arm and the patient-specific support can position the instrument and the guide surface in a predetermined location and orientation relative to the anatomical surface of the patient with increased stability.

DEVICES AND METHODS FOR SHAPING A TOOTH
20220008163 · 2022-01-13 ·

Disclosed herein is a mountable dental device for shaping a tooth of a subject. The device includes: (i) an anchoring member configured to be removably affixed to a jaw of a subject by securing thereof to one or more teeth of the subject, and (ii) a computerized numerical control (CNC) machine fixedly mounted or mountable on the anchoring member. The CNC machine is configured to have installed thereon and maneuver a dental turbine. When the anchoring member is affixed to the jaw, the device is supported by the subject. The anchoring member is adjustable such as to allow the affixing thereof to jaws of different subjects. The CNC machine is configured to control operation of the dental turbine in at least one dental tooth-shaping procedure on at least one tooth of the subject.
