Abstract:
1. A computer-implemented method for design of a connector between a first dental restoration component and a second dental restoration component of a dental prosthesis, comprising: displaying, from a cross-sectional viewpoint, in a first frame of a computer-based interface, displaying, from a user selected viewpoint different from the cross-sectional viewpoint and rendered in three dimensions, in a second frame of the computer-based interface distinct from the first frame, receiving a modification based on operator input representing a manipulation by the operator of the first connection curve in the first frame or the third connection curve in the second frame; determining whether the modification is acceptable with respect to the acceptability design constraint; and providing a visual indication to the operator via both the first frame and the second frame based at least in part on whether the modification is acceptable with respect to the acceptability design constraint, the visual indication providing an indication that the first connection curve or the third connection curve overlaps an unacceptable production area, the method performed programmatically by a computer-aided design system that comprises one or more physical computers.
