Abstract

A computer-implemented method for comparing digital 3D dental models is disclosed, wherein the method comprises receiving a first digital 3D dental model representative of a dental situation at a first time, receiving a second digital 3D dental model representative of the dental situation at a second time, wherein the second time is later than the first time. Further, the method comprises generating a difference map based on the first digital 3D dental model and the second digital 3D dental model, where generating of the difference map comprises obtaining values of geometric differences between the first digital 3D dental model and the second digital 3D dental model, identifying a greatest value of geometric differences from the values of geometric differences, generating a color scale comprising a plurality of discrete colors associated with the values of geometric differences, wherein colors of the plurality of discrete colors are separated by color scale threshold values, further wherein the color scale threshold values are generated based on the greatest value of geometric differences, and assigning the plurality of discrete colors to the values of geometric differences. The method further comprises displaying the difference map to visually highlight the values of geometric differences between the first digital 3D dental model and the second digital 3D dental model.
