Abstract: Computer-implemented method for digitally shortening a cap of a dental bridge comprising steps of (a) loading 3D data of the bridge from a computer-readable storage medium or generating 3D data of the bridge with a modelling software, the 3D data comprising cap data and bar data; (b) determining intersection points of a bar with geometrical features of the cap; and in case that a further bar is attached to the cap, repeating step (b); (c) determining from said intersection points an intersection point with the biggest z value; (d) performing a cut of the cap along a cutting surface, the location of which is based on said intersection point with the biggest z value; (e) defining data of a portion of the cap below the cutting surface as shortened cap. Further disclosed is a computer-readable medium for performing the method steps.

Abstract: Computer-implemented method for virtually modifying a digital model of a dental restoration, wherein a user selects a point on the surface of the dental restoration, wherein a sphere having the selected point as its centre is automatically displayed, wherein the user may define to add material to or remove material from the dental restoration inside the sphere to generate a modified part of the dental restoration and leaving the rest of the dental restoration unmodified, wherein the step of adding material to or removing material from the dental restoration is automatically performed in real time on a display. Further, the invention is related to a computer-readable medium having stored thereon instructions which when executed by a processor perform the method steps of the inventive computer-implemented method.
