1. A system for performing quality control on a physical dentition model, the system comprising:
a fabrication module selected from the group comprising an injection molding system, a lathing and milling system, or a 3D printing system, the fabrication module configured to manufacture a physical dentition model that is based upon a virtual model of a patient's dentition;
a dentition model scanner configured to scan the physical dentition model to thereby obtain a scanned model; and
a quality control module comprising a processor and a non-transitory computer-readable storage medium comprising instructions executable by the processor to determine whether the manufactured physical dentition model is a good or a defective product based on a statistical characteristic of a differences model generated by comparing spatial points of the virtual model of the patient's dentition and corresponding best-fitting points of the scanned model to compile offsets between the spatial points of the virtual model and the corresponding best-fitting spatial points of the scanned model.
