Patent number: 11426053Abstract: Processing logic makes a comparison between first image data and second image data of a dental arch and determines a plurality of spatial differences between a first representation of the dental arch in the first image data and a second representation of the dental arch in the second image data. The processing logic determines that a first spatial difference is attributable to scanner inaccuracy and that a second spatial difference is attributable to a clinical change to the dental arch. The processing logic generates a third representation of the dental arch that is a modified version of the second representation, wherein the first spatial difference is removed in the third representation, and wherein the third representation comprises a visual enhancement that accentuates the second spatial difference.Type: GrantFiled: September 25, 2019Date of Patent: August 30, 2022Assignee: Align Technology, Inc.Inventors: Sergei Ozerov, Ofer Saphier, Avi Kopelman, Adi Levin, Pavel Razumovskiy, Michael Sabina, Mikhail Dyachenko, René M.
