Abstract
A processing device receives a first intraoral image of a first region of a dental site and a second intraoral image of a second region of the dental site during an intraoral scan session. The processing device determines that the first intraoral does not overlap with the second intraoral image. The processing device registers the first intraoral image to the second intraoral image in a three-dimensional space according to a historical template, wherein the historical template is a virtual model of the dental site as generated from additional intraoral images taken during a previous intraoral scan session.
