Abstract

The invention discloses an artificial tooth root or joint material capable of releasing zinc and cerium trace elements and having a nano / micron porous surface structure and a microarc oxidation preparation method thereof. The artificial tooth root or joint is prepared from a pure titanium or titanium alloy matrix and a porous titanium dioxide bioactive surface layer, wherein the porous titanium dioxide bioactive surface layer is obtained on the surface of the pure titanium or titanium alloy matrix by using a microarc oxidization technology and doped with the trace zinc and cerium elements, the pore diameter of the porous titanium dioxide bioactive surface layer is changed between 50nm and 500nm, thus the surface bacteriostatic capacity, the bioactivity and the cell regulation and control capacity of the initial implanted surface can be improved remarkably, and multiple beneficial functions are obtained. The preparation method comprises the steps of: firstly processing the artificial tooth root (joint) by selecting pure titanium or titanium alloy; then obtaining the titanium dioxide bioactive surface layer with the nano-micro porous structure on the surface of the artificial tooth root (joint) by adopting a microarc oxidization technology; meanwhile adding zinc and cerium soluble salts to electrolyte and carrying out synchronous doping by utilizing a microarc oxidization process.
