Patent ID: 7661956

Claim:
A method of positioning an implant analog in a modified stone model of a patient's dentition for use in creating a patient specific prosthesis, comprising: preparing a stone model of a patient's dentition including teeth models and informational markers indicative of information concerning a dental implant installed in the patient's mouth; scanning the stone model; generating scan data from the scanning of the stone model; transferring the scan data to a CAD program; creating a three-dimensional model of at least a portion of the stone model on the CAD program using the scan data; determining the informational markers to gather information for manufacturing an abutment; developing abutment dimensional information based on the three-dimensional model and the information from the informational markers; developing implant analog positional information on the CAD program based on the information from the informational markers; transferring the implant analog positional information to a robot manipulator; modifying the stone model by removing a portion of the stone model in the region of the informational markers; and placing the implant analog on the modified stone model using the robot manipulator and the implant analog positional information.
