Guidance for positioning and orienting field of view of intraoral scanning

A system for scanning an intraoral cavity, comprising:

• an intraoral scanner configured to generate topographical scan data of the intraoral cavity and two-dimensional (2D) image data of the intraoral cavity, wherein the two-dimensional image data represents at least a portion of a field of view of the intraoral scanner;
• and
• a computing device configured to:
• receive the topographical scan data and the two-dimensional image data from the intraoral scanner;
• generate a three-dimensional (3D) digital model of the intraoral cavity using the topographical scan data;
• output the 3D digital model and the 2D image data to a display;
• determine which portions of the intraoral cavity have been scanned based on at least one of the topographical scan data or the 2D image data;
• generate a visual indicator that provides guidance for positioning and orienting the field of view of the intraoral scanner based at least in part on which portions of the intraoral cavity have been scanned;
• and
• output the visual indicator to the display.
