Abstract: Embodiments relate to techniques for assisting users of intraoral scanners during intraoral scanning. In an embodiment, a method includes receiving intraoral scans of a dental site, generating a 3D surface of the dental site based on the intraoral scans, determining a surface quality score for a region of the 3D surface, and outputting a view of the 3D surface to a display, wherein the region of the 3D surface is shown with a visualization associated with the surface quality score.

Abstract: An apparatus for intraoral scanning comprises an elongate wand comprising a probe at a distal end of the wand, one or more cameras and a computer processor. The one or more cameras are disposed within the probe and arranged within the probe such that the one or more cameras receive rays of light from an intraoral cavity in a non-central manner, wherein the non-central manner in which the one or more cameras receive the rays of light from the intraoral cavity introduces image distortion. The computer processor is configured to generate a three-dimensional model of an intraoral surface based on images from the one or more cameras, wherein the computer processor compensates for the image distortion specifically introduced by the non-central manner in which the one or more cameras receive the rays of light from the intraoral cavity.
