Abstract: A computer implemented method for rendering digital three-dimensional dental models includes receiving a first digital 3D dental model including a first dental information of a patient; receiving a second digital 3D dental model including a second dental information of the patient; generating, in the digital 3D space, a superimposed model by superimposing one of the first digital 3D dental model or the second digital 3D dental model on another of the second digital 3D dental model or the first digital 3D dental model; and arranging a 2D controller and the superimposed model relative to each other such that a position of the 2D controller defines a boundary that demarcates the superimposed model between a first zone and a second zone.

Abstract: Disclosed is a system and method for presenting a graphical representation of an oral situation of a patient over time. In particular the system and method relates to a method of presenting a plurality of scans taken over time in manner where the focus on the changes in the oral situation of the patient is maintained.
