Preparation method of personalized biphase condylar scaffold

The invention discloses a preparation method of a personalized biphase condylar scaffold. The preparation method comprises the following steps of separating a mandible digital model by collecting data; selecting data on the opposite side of a lesion area in the mandible digital model, mapping the data to the lesion area in a mirror symmetry manner to obtain a condylar head and neck prosthesis model, and designing and printing a bone phase scaffold according to a condylar tissue structure form; preparing a cartilage phase scaffold; and spraying a compact layer on the surface of the head of the bone phase scaffold, connecting the cartilage phase scaffold with the compact layer through a dissolution-adhesion process to form a compact layer bone-cartilage composite scaffold, constructing a condylar biphase composite scaffold, and after a position retaining handle is designed on the condylar biphase composite scaffold, constructing the personalized biphase bionic condylar scaffold. The problems that the condylar f
