In embodiments, a system for scanning an intraoral cavity comprises an intraoral scanner to generate intraoral scan data of the intraoral cavity and viewfinder images of the intraoral cavity, a display, and a processing unit operatively connected to the intraoral scanner and to the display. The processing unit is to: receive the intraoral scan data and the viewfinder images from the intraoral scanner; generate a three-dimensional (3D) digital model of the intraoral cavity using the intraoral scan data; output the 3D digital model to the display; output the viewfinder images to the display; determine which portions of the intraoral cavity have been scanned; determine a current field of view of the intraoral scanner; determine a visual indicator that provides guidance for positioning and orienting the field of view of the intraoral scanner; and output the visual indicator to the display.
