  • Patent number: 11173011
    Abstract: Methods and systems for tracking a dental tool within an oral cavity for taking and/or updating of a dental impression are described. In some embodiments, a marker, optionally a magnetic marker, is coupled to position movements of a rotatable dental tool. In some embodiments, detected movements of the marker are used, optionally in combination with other tracking data, to map contours which a portion of the rotatable dental tool follows during interaction with a dental surface. Optionally, the interaction occurs during grinding, drilling, and/or other procedures; which may be preparatory, for example, to the manufacture and/or fitting of a dental prosthetic.

  • Patent number: 11020208
    Abstract: Methods and devices are disclosed, by use of which an external fiducial element positioned in the mouth serves as a geometrical constraint on oral arch geometry. In some embodiments, the fiducial element is an oral insert which reaches to a plurality of oral arch regions to present surface details which are in well-defined distance and/or angular relationships to one another. These spatial relationships optionally comprise a spatial frame of reference which serves to constrain reconstruction of the geometry of one or both of the oral arches, for example reconstruction from a collection of digitally registered, partially-overlapping scans made along the oral arch.

  • Publication number: 20200155285
    Abstract: An intra oral scanner (IOS) including a probe is disclosed. Optionally, the probe is calibrated to measure locations at a higher accuracy than the IOS. For example, the probe may be used to locate points in a 3D map at high precision and/or the points used to increase the precision of location of other points and/or surfaces in the map. In some embodiments, the probe includes a sensor. Optionally, the probe may be used to measure locations that are hard to view with the IOS. For example, the IOS probe combination may be used to produce 3D maps of a recess in a tooth and/or gums and/or a periodontal pocket and/or to traduce a 3D map or periodontal disease. In some embodiments the probe may be used to measure physical properties, for example, the IOS probe combination may be used to produce a 3D image of hardness of mucosa.
