Abstract

A porous bionic skull repairing material includes a polymer material, whose structure is consistent with that of a human skull. The surface layers of the porous bionic skull repairing material are dense layers which are composed of non-degradable or degradable polymer materials and has blind holes having an asymmetric structure, and the inner layer of the porous bionic skull repairing material is a loose layer which has a porous structure. The repairing material can be molded by adopting a mixed mould pressing method or a 3D printing method, simulates a bone structure, with two dense sides and a loose middle, of a human skull to the greatest extent.
