Publication number: 20200397273Abstract: The present disclosure provides methods, computing device readable medium, devices, and systems that utilize a cheek retractor and/or a mobile device holder for case assessment and/or dental treatments. One cheek retractor includes a first and a second lip holder, both including imaging markers of a predetermined size to determine a scale of teeth of a user, where each imaging marker is located a predefined distance from the remaining imaging markers, and where the lip holder is to hold a cheek away from a mouth of a user to expose teeth of the user. A mobile device holder can include elements to receive a mobile device to capture images of the patient's teeth.Type: ApplicationFiled: September 4, 2020Publication date: December 24, 2020Inventors: Eric P. MEYER, Roman A. ROSCHIN, Tzishing Jesse LIM, Palak MITTAL, Stephan Albert Alexandre Dumothier, Norman C. SU, Huameng Ivan CHU

Publication number: 20200352681Abstract: Two or more adjacent teeth in a virtual model are determined. The two or more adjacent teeth include a first tooth adjacent to a second tooth in the virtual model. The virtual filler is inserted in the virtual model between the first tooth and the second tooth. Points in the virtual model are selected. The points and the virtual filler are transformed into a voxel volume. A geometry of an updated virtual filler is determined by transforming a surface of the voxel volume into a polygonal mesh.Type: ApplicationFiled: July 22, 2020Publication date: November 12, 2020Inventors: Israel Velazquez, Andrey Cherkas, Stephan Albert Alexandre Dumothier, Anatoliy Parpara, Alexey Geraskin, Yury Slynko, Danila Chesnokov

Publication number: 20200357116Abstract: A method for analyzing a quality of an orthodontic aligner is described. The method includes receiving, by a processor, a digital representation of a fabricated orthodontic aligner, the digital representation having been generated based on imaging of the fabricated orthodontic aligner. The method further includes analyzing, by the processor, the digital representation of the fabricated orthodontic aligner to identify a quality-related property of the fabricated orthodontic aligner. The method further includes determining, based on the quality-related property, that the fabricated orthodontic aligner comprises a manufacturing flaw. The method further includes classifying, by the processor, the fabricated orthodontic aligner as requiring further inspection by a technician based on determining that the fabricated orthodontic aligner comprises the manufacturing flaw.Type: ApplicationFiled: July 23, 2020Publication date: November 12, 2020Inventors: Anatoliy Parpara, Ivan Kharpalev, Stephan Albert Alexandre Dumothier, Andrey Cherkas, Alexey Kalinichenko, Jack Shaw, Israel Velazquez

Publication number: 20200242765Abstract: A system for inspecting a customized dental device associated with a dental application for manufacturing defects is disclosed. The system obtains images of the customized device and identifies an identifier of the customized device. The system determines a digital file associated with the customized device based on the identifier, the digital file including a first digital model of the customized device and/or a second digital model of a mold used during manufacture of the customized device. The system determines an intended property for the customized device based on at least one of the first digital model or the second digital model, determines an actual property of the customized device from the images, determines whether there is a manufacturing defect in the customized device by comparing the intended property for the customized device with the actual property of the customized device, and outputs an output associated with the determination.Type: ApplicationFiled: April 16, 2020Publication date: July 30, 2020Inventors: Anatoliy Parpara, Ivan Kharpalev, Stephan Albert Alexandre Dumothier, Andrey Cherkas, Alexey Kalinichenko, Jack Shaw, Israel Velazquez

Patent number: 10722328Abstract: A processing device determines two or more adjacent teeth in a virtual model, the two or more adjacent teeth include a first tooth adjacent to a second tooth in the virtual model. The processing device inserts a first virtual filler in the virtual model between the first tooth and the second tooth. The processing device selects points in the virtual model. A processing device transforms the plurality of points into a voxel volume comprising a plurality of voxels. A processing device performs a smoothing operation on the voxel volume. A processing device subsequent to performing the smoothing operation on the voxel volume, determines a geometry of an updated virtual filler by transforming a surface of the smoothed voxel volume into a polygonal mesh.Type: GrantFiled: October 3, 2018Date of Patent: July 28, 2020Assignee: Align Technology, Inc.Inventors: Israel Velazquez, Andrey Cherkas, Stephan Albert Alexandre Dumothier, Anatoliy Parpara, Alexey Geraskin, Yury Slynko, Danila Chesnokov
