Augmented reality enhancements for dental practitioners

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.
