The invention discloses a method for realizing digitized molding of an autogenous tooth transplantation accessory. The method comprises the following steps: after obtaining a jaw bone model by using a CT scanner, obtaining a resinous material jaw bone corresponding to the jaw bone model through 3D printing, and obtaining a metallic titanium mesh retention guide plate corresponding to a metallic titanium mesh retention guide plate model through the 3D printing. In the printing process, a regional frame selection command of a user, which is on the jaw bone model, can be received as well so as to correspondingly generate a relevant guide plate model. According to the method, utilizing autogenous teeth such as a wisdom tooth to transplant is realized, the resinous material jaw bone, an intraoral ring incision guide plate and the metallic titanium mesh retention guide plate are quickly obtained through digitized design so as to assist in the transplantation of the autogenous teeth, and the method can be more conveniently used by the user in the operation process.
