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.
