Claim 12:
13. A system comprising:
an intraoral scanner to generate a plurality of intraoral images of a dental site of a patient; and
a computing device comprising a memory and a processor, the computing device operatively connected to the intraoral scanner, wherein the computing device is to:
receive the plurality of intraoral images of the dental site during an intraoral scan session, the plurality of intraoral images comprising a first intraoral image and a second intraoral image;
generate a first surface of a first region of the dental site based on the first intraoral image;
generate a second surface of a second region of the dental site based on the second intraoral image;
register the first intraoral image to a template at the first region of the dental site;
register the second intraoral image to the template at the second region of the dental site;
determine relative positions of the first surface of the first region of the dental site and the second surface of the second region of the dental site based on registration of the first intraoral image to the template and on registration of the second intraoral image to the template, wherein overlap between the first region of the dental site represented in the first intraoral image and the second region of the dental site represented the second intraoral image is insufficient for registration of the second intraoral image to the first intraoral image; and
output the first surface and the second surface having the relative positions to a display, wherein the template is not displayed.
