An artificial bone, as disclosed in this utility model, comprises of a bionic bone, a pillar of support, and a multi-dimensional porous scaffold structure; said pillar of support and said multi-dimensional porous scaffold structure are connected to said bionic bone while the said multi-dimensional porous scaffold structure is inside the said pillar of support. The beneficial effects of this utility model are: artificial bone is utilized to replace the original bone. In the meantime, a pillar of support and a multi-dimensional porous scaffold structure are set inside the artificial bone. The pillar of support extends into the connection part of the original bone for support and fixation. The periphery the connection part of the original bone is set with a multi-dimensional porous scaffold structure, providing space for bone cells to attach and grow. Thus, the connecting part between the artificial bone and the original bone are steadier.
