Publication number: 20230181295Abstract: 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.Type: ApplicationFiled: February 9, 2023Publication date: June 15, 2023Applicant: Dentlytec G.P.L.

Patent number: 11529056Abstract: According to some embodiments there is provided a method for structured light scanning of an intra-oral scene, comprising: projecting onto the intra-oral scene a color-coded pattern comprising an arrangement of entities having edges between them; each entity comprising a different narrow band of wavelengths; and detecting the projected pattern as a plurality of pixels in an acquired image of the scene using at least two narrowband filters, wherein for each pixel of at least 95% of the pixels of an entity of interest comprising a first band of wavelengths, a contribution of light from a second band of wavelengths of an adjacent entity is less than 10%. Some embodiments relate to a scanner system for structured light scanning of an intra-oral scene.Type: GrantFiled: October 18, 2017Date of Patent: December 20, 2022Assignee: Dentlytec G.P.L.

Publication number: 20220261574Abstract: Characteristics of a user's movement are evaluated based on performance of activities by a user within a field of view of a camera. Video data representing performance of a series of movements by the user is acquired by the camera. Pose data is determined based on the video data, the pose data representing positions of the user's body while performing the movements. The pose data is compared to a set of existing videos that correspond to known errors to identify errors performed by the user. The errors may be used to generate scores for various characteristics of the user's movement. Based on the errors, exercises or other activities to improve the movement of the user may be determined and included in an output presented to the user.Type: ApplicationFiled: February 16, 2021Publication date: August 18, 2022Inventors: EDUARD OKS, RIDGE CARPENTER, LAMARR SMITH, CLAIRE MCGOWAN, ELIZABETH REISMAN, IANIR IDESES, ELI ALSHAN, MARK KLIGER, MATAN GOLDMAN, LIZA POTIKHA, IDO YERUSHALMY, DOTAN KAUFMAN, GUY ADAM, OMER MEIR, LIOR FRITZ, IMRY KISSOS, GEORGY MELAMED, ERAN BORENSTEIN, SHARON ALPERT, NOAM SOREK

Publication number: 20220071737Abstract: 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.Type: ApplicationFiled: November 15, 2021Publication date: March 10, 2022Applicant: Dentlytec G.P.L.

Patent number: 11020208Abstract: 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.Type: GrantFiled: April 21, 2016Date of Patent: June 1, 2021Assignee: DENTLYTEC G.P.L. LTD.Inventors: Benny Pesach, Georgy Melamed, Blanc Zach Lehr, Ygael Grad
