Patent ID: 8769822

Claim:
A method for manufacturing a dental prosthesis including a coping and a crown, the method comprising: obtaining an electronic model of the dental prosthesis including an electronic model of the crown seated on an electronic model of the coping; determining a height of the dental prosthesis based on the electronic model of the dental prosthesis when the electronic model of the crown is positioned appropriately on the electronic model of the coping to simulate a proper seating of the crown on the coping; obtaining a coping fabricated based on the electronic model of the coping; obtaining a pattern of the crown based on the electronic model of the crown; obtaining an electronic model of a preparation die; determining a suitable height for the preparation die based on the height of the dental prosthesis and a height of a seating jig; modifying the electronic model of the preparation die to have the determined suitable height; fabricating the preparation die with the determined suitable height based on the electronic model of the preparation die; forming a manufacturing arrangement including mounting the coping on the preparation die and mounting the pattern of the crown on the coping; mounting the manufacturing arrangement on the seating jig; and analyzing a relationship between the manufacturing arrangement and the seating jig to determine whether the pattern of the crown is seated appropriately on the coping.
