Patent ID: 8386062

Claim:
A method of preparing a digital model and an artificial tooth applied to dental implant, comprising steps of: a) arranging a jig under a condition that there is a fixture in a patient's oral cavity, the fixture having a connection interface formed at a top side thereof, the jig having a feature and an abutting interface, the abutting interface being formed at a bottom side of the jig and corresponding to the connection interface, the feature being exposed outside the fixture and dental gum in the patient's oral cavity, the connection interface being combined with the abutting interface to enable the jig to be combined into the fixture; and scanning the patient's oral cavity by an oral scanner to acquire a first oral digital data and then saving it in a computer; b) operating the computer to select one of digital prostheses, each of which overlaps a digital jig having a digital feature corresponding to the feature of the jig, from a prosthetic database in the computer, combining the selected digital prosthesis and the first oral digital data by the overlap of the feature of the digital jig and that of the jig in the first oral digital data, and then removing the jig and the digital jig from the first oral digital data to generate a second oral data; c) generating a digital oral model based on the second oral digital data; and d) preparing a solid oral model based on the digital oral model, the digital prosthesis being substantialized to become a propositional prosthesis.
