The invention discloses a high-tissue-affinity corrosion-resisting implant tooth and a manufacturing method thereof. The high-tissue-affinity corrosion-resisting implant tooth comprises a tooth implant body and an expansion core, wherein the tooth implant body takes a titanium alloy as a base material, and a tantalum metal layer and a tantalum oxide plating layer are plated on an outer layer; the tantalum metal layer and the tantalum oxide plating layer are manufactured through a physical vapor deposition technology of multi-arc ion plating or magnetron sputtering plating; and the expansion core takes a titanium alloy as a base material, and a titanium-tantalum alloy plating layer and a tantalum-silver alloy plating layer are plated on the outer layer. The implant tooth disclosed by the invention has good high tissue affinity, good corrosion resistance and good biocompatibility; and a preparation method of the composite material disclosed by the invention is simple, and the plating layer is combined with the base material very well.
