  • 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.

  • Patent number: 10823635
    Abstract: Optical apparatus includes a diffractive optical element (DOE), which includes multiple optical surfaces, including at least an entrance surface and an exit surface, and a side surface, which is not parallel to the optical surfaces of the DOE. A grating is formed on at least one of the optical surfaces so as to receive radiation entering the DOE via the entrance surface and to diffract the radiation into a predefined pattern comprising multiple diffraction orders that exit the DOE via the exit surface. An optical detector is positioned in proximity to the side surface so as to receive and sense an intensity of a high order of the radiation diffracted from the grating that passes through the side surface of the DOE.

  • 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.
