Abstract
A physical preform suitable for a screw retained dental restoration (“SRR”) includes a sintered preform and an insert receiving region within at least a portion of the sintered preform. A computer-implemented method of providing a screw retained dental restoration includes receiving a virtual restoration mode and generating one or more virtual spiral toolpaths corresponding to a virtual restoration shape of the virtual restoration model. A computer-implemented method of correcting preform placement during milling includes probing one or more surface points of a preform mounted to a milling machine using a grinding bur of the milling machine and determining one or more preform alignment parameters based on a distance traveled by the grinding bur to the one or more surface points.
