Abstract: An image of a dental arch comprising a preparation tooth is generated by an image capture device associated with an augmented reality (AR) display. The image of the dental arch is registered to previous image data associated with the dental arch. A visual overlay associated with a dental prosthetic to be placed on the preparation tooth is generated based on the registering of the image of the dental arch to the previous image data associated with the dental arch. The visual overlay is output to the AR display, wherein the visual overlay is superimposed over a view of the preparation tooth on the AR display.

Abstract: A system comprises a scanner, an augmented reality (AR) display and a computing device. The scanner generates intraoral images of a dental arch and the AR display generates additional image data representative of a view from a wearer of the AR display. The computing device receives the intraoral images from the intraoral scanner, generates a virtual three-dimensional model of at least a portion of the dental arch from the intraoral images, receives the additional image data from the AR display, determines, from the additional image data, a region of the view that is outside of the dental arch, generates a visual overlay comprising the virtual three-dimensional model, and sends the visual overlay to the AR display. The AR display displays the visual overlay such that the virtual three-dimensional model is shown in the region of the view that is outside of the dental arch.
