System, device, and method for intraoral scanning accuracy
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.

A method for intraoral scanning, including introducing an intraoral scanner (IOS) head into an oral cavity, acquiring an image of a field of view (FOV), processing the acquired FOV image and adjusting at least one image acquisition parameter based on said processing, and an intraoral scanner (IOS) including an IOS head including at least one imager imaging a field of view (FOV), at least on light emitter that illuminates said FOV and circuitry that controls said imager and/or said light emitter.

A method for measuring regions of a tooth in a mouth including: measuring at least one surface point on a surface of the tooth with respect to an element mechanically coupled to said surface point; determining a location of at least one visible reference mechanically coupled to said surface point with respect to said element; estimating a location of said surface point with respect to said visible reference. A device used for such measuring may include a main body comprising a final optical element of an imager which defines an optical field of view directed in a first direction; and a measurement element coupled to said main body extending generally in said first direction; where a tip of said measurement element is sized and shaped to be inserted between a tooth and adjacent gingiva; where said optical field of view is sized to image at least part of a tooth.

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.
There is provided according to some embodiments, a system, device and method for a three dimensional (3D) intraoral scanning of at least a portion of a tooth. An intraoral scanner may include a shadow casting object extending between a light emitter and the portion of the tooth. An imaging module may image the portion of the tooth and/or the projected shadow of the shadow casting object. A method to construct a 3D model may include illuminating at least a portion of the tooth with a light emitter; casting a shadow on the portion of the tooth by an object located between the emitter and the tooth; imaging the portion of the tooth, including at least a part of the shadow; and determining a location of a point on the tooth and related to the shadow, using the image.
