Abstract: A system for intraoral scanning comprises a scanner to generate image data of a dental site and a computing device. The computing device analyzes the image data to identify a captured surface pattern on a reference object at the dental site, identifies the reference object and determines a position and orientation of the reference object at the dental site based at least in part on the captured surface pattern on the reference object, and generates a three-dimensional (3D) model of the dental site based at least in part on the image data, wherein the identified reference object is used to augment the 3D model of the dental site.

Abstract: An intraoral scanner generates 2D images of a dental site and 3D intraoral scans of the dental site. The computing device receives the 2D images of the dental site and the 3D intraoral scans of the dental site from the intraoral scanner, generates a 3D model of the dental site based on the 3D intraoral scans of the dental site, and processes at least one of a) one or more of the 2D images of the dental site, b) one or more of the 3D intraoral scans of the dental site, or c) data from the 3D model of the dental site to identify one or more intraoral areas of interest (AOIs) at the dental site. The computing device determines a dental condition associated with the one or more intraoral AOIs, and determines a manner for scanning the one or more intraoral AOIs.

Abstract: A processor receives first intraoral scan data comprising a first depiction of a dental site; generates a virtual three-dimensional (3D) model of the dental site using the first intraoral scan data; and processes at least one of the first intraoral scan data or data from the virtual 3D model to identify an unclear feature. The processor outputs instructions to generate second intraoral scan data of the dental site depicting the portion of the dental site that is unclear; receives the second intraoral scan data; and updates the virtual 3D model of the dental site using the second intraoral scan data, wherein the portion of the dental site that was unclear in the virtual 3D model is replaced with information from the second intraoral scan data.
