Abstract
A processing device receives intraoral scan data comprising a plurality of intraoral images of a dental site generated during scanning of the dental site by an intraoral scanner, one or more ink markings or other non-rigid indicia having been applied to the dental site prior to the scanning of the dental site, wherein at least two intraoral images of the plurality of intraoral images comprise representations of the one or more ink markings or other non-rigid indica. The processing device performs registration between the plurality of intraoral images and generates a three-dimensional (3D) model of the dental site using the plurality of intraoral images that have undergone registration, the 3D model of the dental site comprising a representation of the one or more ink markings or other non-rigid indica that were applied to the dental site prior to the scanning of the dental site.
