Abstract
Methods and systems for scanning an intraoral cavity of a patient provide capturing one or more viewfinder images of the intraoral cavity and scanning the intraoral cavity with an intraoral scanner to generate one or more topography scans of the intraoral cavity. The one or more topography scans may correspond to the one or more viewfinder images. The methods and systems further provide capturing a viewfinder image of a portion of the intraoral cavity, the viewfinder image overlapping with the one or more viewfinder images. An area of overlap of the viewfinder image with the one or more viewfinder images can be determined. One or more indicators of the area of overlap can be displayed on one or more locations of a display in order to provide guidance for positioning a field of view of the intraoral scanner.
