Method for designing a digital abutment for dental implant

[0021]Referring to FIG. 1, a method for designing a digital abutment for a dental implant fixture in accordance with a first embodiment of the present invention includes the steps of:

[0022]a) Implant planning: As shown in FIGS. 2 and 3, initiate implant planning based on the digital data obtained from the patient and loaded into the computer system to enable the implant fixture 11 (see FIG. 4) to be implanted at the implant site in the best position. The computer has the data of the digital oral cavity model of the patient. The data of the digital oral cavity model includes a digital gum 13 and a digital crown 23. The digital gum 13 and the digital crown 23 can be loaded from a digital database (not shown) of the computer system. Alternatively, the digital data can be loaded by means of scanning a gum / crown model made subject to the configuration of the oral cavity of the patient.

[0023]b) Establishment of digital reference abutment: As shown in FIGS. 4˜6, a digital reference abutment
