ABSTRACT:
A method of manufacturing custom crown coping and infrastructures is provided. A metal portion (base) of an abutment is located in a model of a patient's mouth and the model is scanned. The data from the scan is then utilized to manufacture the ceramic portion of the abutment and the coping. In one embodiment, the coping and infrastructure is designed by first determining the shape and orientation of the final crown, subtracting a thickness for the crown from the shape to determine the shape and orientation of a coping, and subtracting a thickness for the coping to form the shape and orientation of an abutment.
