IMPLANT HAVING HIGH QUALITY SURFACE AND METHOD FOR SURFACE TREATMENT OF IMPLANT

摘要

An implant in which the surface is reformed and an implant surface processing method are provided to enhance the coherence of the implant and the brain. An implant in which the surface is reformed comprises: a substrate(10) formed of roughness of micro-unit; a barrier layer(20) of the substrate surface; and a nano-tube layer(30) on the barrier layer. The substrate can be made of the pure titanium or made of the titanium alloy by adding one or more metal selected from the aluminum(Al), tantalum(Ta), niobium(Nb), vanadium(V), zirconium(Zr), platinum(Pt), magnesium(Mg), and sodium(Na).
