Patent number: 10713396Abstract: Methods for aligning a digital 3D model of teeth represented by a 3D mesh to a desired orientation within a 3D coordinate system. The method includes receiving the 3D mesh in random alignment and changing an orientation of the 3D mesh to align the digital 3D model of teeth with a desired axis in the 3D coordinate system. The methods can also detect a gum line in the digital 3D model to remove the gingiva from the model.Type: GrantFiled: December 12, 2018Date of Patent: July 14, 2020Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Guruprasad Somasundaram, Evan J. Ribnick, Ravishankar Sivalingam, Shannon D. Scott, Golshan Golnari, Aya Eid

Patent number: 10602127Abstract: A 3D imaging apparatus with enhanced depth of field to obtain electronic images of an object for use in generating a 3D digital model of the object. The apparatus includes a housing having mirrors positioned to receive an image from an object external to the housing and provide the image to an image sensor. The optical path between the object and the image sensor includes an aperture element having apertures for providing the image along multiple optical channels with a lens positioned within each of the optical channels. The apparatus also includes a transparent cover positioned within the optical path and having a plurality of fiducials. The depth of field of the apparatus includes the cover, allowing the fiducials to be used to calibrate the apparatus or verify and correct the existing calibration of it.Type: GrantFiled: October 16, 2019Date of Patent: March 24, 2020Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: David B. Stegall, Vladimir Kryzhniy, Eric S. Hansen, Aya Eid, Shannon D. Scott, Zhisheng Yun, James L. Graham, II

Patent number: 10410346Abstract: A method for detecting tooth wear using digital 3D models of teeth taken at different times. The digital 3D models of teeth are segmented to identify individual teeth within the digital 3D model. The segmentation includes performing a first segmentation method that over segments at least some of the teeth within the model and a second segmentation method that classifies points within the model as being either on an interior of a tooth or on a boundary between teeth. The results of the first and second segmentation methods are combined to generate segmented digital 3D models. The segmented digital 3D models of teeth are compared to detect tooth wear by determining differences between the segmented models, where the differences relate to the same tooth to detect wear on the tooth over time.Type: GrantFiled: March 3, 2017Date of Patent: September 10, 2019Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Guruprasad Somasundaram, Evan J.

Patent number: 10405796Abstract: Methods for estimating and predicting tooth wear based upon a single 3D digital model of teeth. The 3D digital model is segmented to identify individual teeth within the model. A digital model of a tooth is selected from the segmented model, and its original shape is predicted. The digital model is compared with the predicted original shape to estimate wear areas. A mapping function based upon values relating to tooth wear can also be applied to the selected digital model to predict wear of the tooth.Type: GrantFiled: July 20, 2017Date of Patent: September 10, 2019Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Evan J. Ribnick, Guruprasad Somasundaram, Brian J. Stankiewicz, Aya Eid, Ravishankar Sivalingam, Shannon D. Scott, Anthony J. Sabelli, Robert D. Lorentz
