  • ANALYSIS AND VISUALIZATION OF DENTAL ARCH OVER TIME
    Publication number: 20220346629
    Abstract: A processing device may execute instructions from a computer readable medium to perform operations comprising: making a comparison between first image data of at least a portion of a dental arch and second image data of at least the portion of the dental arch; determining a plurality of differences between a first representation of at least the portion of the dental arch in the first image data and a second representation of at least the portion of the dental arch in the second image data; determining that a first difference of the plurality of differences is attributable to tooth movement; determining that a second difference of the plurality of differences is attributable to tooth wear to one or more teeth on at least a portion of the dental arch; and generating a third representation of at least the portion of the dental arch that is a modified version of the second representation, wherein a visual indication of the tooth wear is provided in the third representation.

  • Analysis and visualization of a dental arch under a limited accuracy system
    Patent number: 11426053
    Abstract: 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.

  • LONGITUDINAL ANALYSIS AND VISUALIZATION UNDER LIMITED ACCURACY SYSTEM
    Publication number: 20200037848
