1. A computer-implemented method for providing fabrication data useful in the fabrication of a wax model of a dental coping configured to fit a tooth preparation, the method comprising: receiving a three-dimensional (3D) virtual model of a patient's intraoral cavity comprising the tooth preparation; receiving a user input command to define a finish line on the 3D virtual model of the tooth preparation; generating a 3D virtual model of a dental coping based on the finish line and having an inner surface and an external surface offset from the inner surface, the inner surface being configured to fit over at least a portion of the tooth preparation, the external surface of the dental coping being disposed between the inner surface of the dental coping and an external surface of a tooth prosthesis; generating a computerized numerical control (CNC) set of wax fabrication instructions based on the 3D virtual model of the dental coping; outputting fabrication data comprising the CNC set of wax fabrication instructions for fabricating the wax model of the dental coping by a milling machine; and fabricating the wax model based on the fabrication data.
