Osseoinductive metal implants for a living body and producing method thereof

A method of producing a metal implant for a living body, the method comprising:

• mechanically processing a titanium alloy to form a metal implant substrate;
• forming a titanium oxide layer on a surface of the processed metal implant substrate with a thickness of 3 nm to 20 nm;
• cleaning a surface of the titanium oxide layer on the metal implant substrate in an alkali degreasing solution;
• cleaning the titanium oxide layer of the metal implant substrate in a plasma atmosphere;
• ionizing a bio-active material selected from a group of consisting of Li, Na, Mg and Ca;
• and
• implanting the ionized bio-active material on the surface of the plasma cleaned titanium oxide layer of the metal implant substrate,
• wherein the ionized bio-active material is implanted on the surface of the plasma cleaned titanium oxide layer with 40 KeV of ion energy,
• wherein the ionized bio-active material is implanted while maintaining a temperature of the plasma cleaned titanium oxide layer at 25° C., and
• wherein the ionized bio-active material is implanted to form a bio-active material layer having a thickness of 0.1 μm.
