1. A method for registering a coordinate system of a physical model of a patient's tooth structure to a coordinate system of a digital model of the tooth structure, the method comprising: forming the physical model of the patient's tooth structure; attaching a pedestal having a known physical characteristic to the physical model; scanning the physical model and the pedestal to generate the digital model of the tooth structure and the pedestal; with a computer, registering the physical model to the digital model based on the known physical characteristic of the pedestal; and mating the pedestal of known physical characteristic into a fixture of manufacturing equipment and registering coordinate systems of the physical and digital models to a coordinate system of the manufacturing equipment.
