Abstract
In general, the invention relates to techniques for registering a three-dimensional (3D) coordinate system of a physical model of a patient's tooth structure to a 3D coordinate system of a virtual model of the same tooth structure. Techniques are described to register the complex geometries of the physical and virtual tooth structures by using a known physical characteristic of a pedestal associated with the physical model.
