Abstract
During an intraoral scan session, a processing device receives a first intraoral image of a dental site and identifies a candidate intraoral area of interest from the first intraoral image. The processing device receives a second intraoral image of the dental site and verifies the first candidate intraoral area of interest as an intraoral area of interest based on comparison of the second intraoral image to the first intraoral image. The processing device then provides an indication of the intraoral area of interest during the intraoral scan session.
Claims21
A method comprising:
- receiving a first intraoral image of a dental site during an intraoral scan session;
- identifying, by a processing device, a first candidate intraoral area of interest from the first intraoral image;
- receiving a second intraoral image of the dental site during the intraoral scan session;
- verifying, by the processing device, the first candidate intraoral area of interest as an intraoral area of interest based on comparison of the second intraoral image to the first intraoral image;
- and
- providing, during the intraoral scan session, an indication of the intraoral area of interest.
A method comprising:
- receiving a plurality of intraoral images of a dental site;
- identifying, by a processing device and based on the plurality of intraoral images, a plurality of voxels satisfying a criterion;
- determining a subset of the plurality of voxels that are proximate to one another;
- grouping the subset of the plurality of voxels into an intraoral area of interest;
- and
- generating, by the processing device, an indication of the intraoral area of interest, wherein the intraoral area of interest is hidden in one or more views of the dental site, and wherein the indication of the intraoral area of interest is visible in the one or more views.
