Patent number: 11918439Abstract: Apparatus for powder-free intra-oral 3D imaging by using a projected texture pattern. A projector projects a random texture pattern of light to teeth to be imaged, and a digital image sensor receives the projected texture pattern from the teeth. The reflected pattern of light reflects and scatters from the teeth. The texture pattern can be a grid having clusters of bright and dark blocks in a pseudo-random arrangement and can provide for powder-free intra-oral 3D imaging by using the pattern to optically simulate powder applied to the teeth. Polarizers can be used in the optical path to transmit the directly reflected light to the image sensor and suppress or discard some of the unwanted scattered light.Type: GrantFiled: February 7, 2019Date of Patent: March 5, 2024Assignee: MEDIT CORP.Inventors: David B. Stegall, Shannon D. Scott, Amanda L. Kastanek

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.
