A method for designing a digital abutment for a dental implant includes the steps of: a) implant planning where implant planning is initiated based on digital data obtained from the patient and loaded into a computer system to enable an implant fixture to be implanted at the implant site in the best position, b) establishment of digital reference abutment where a digital reference abutment is established at the implant site and positioned on the implant fixture, c) adjustment of the digital reference abutment where the digital reference abutment has a subgingival part and a supragingival part at the top side of the subgingival part, and the angle between the subgingival part and the supragingival part is adjusted based on the best prosthesis position, and d) finish of digital abutment where the digital reference abutment becomes a digital abutment for placement after the adjustment.
