Abstract: Methods and systems are described that use a three-dimensional (3D) model of a dental site to generate a panoramic two-dimensional (2D) image of the dental site. In one example, a method includes receiving a 3D model of the dental site generated at least in part from an intraoral scan, generating a surface shaped to substantially surround a dental arch represented by the dental site, computing a surface projection by projecting the dental site onto the surface, and generating the panoramic 2D image from the surface projection.
