The Biological Compatibility of Porous Surface of Titanium Oxide

Abstract

In this study, porous surface structure of Ti/TiO 2 is development for the tooth implant. This kind of structure is made by anode treatment processes with various conditions. The optimized porous surface structure of Ti/TiO 2 is treated in the electrolyte within SO 4 2-and PO 4 3-ions. The pH value of electrolyte is the parameter to modify the roughness of the surface. By the conditions of the experiment, the roughness keeps on submicro level. Moreover, the biological compatibility test, an important experiment of medical devices, is done to confirm the performance of the implant. The results showed that the treated surface feature is suitable for cells growth, and the cell proliferation performance is better than the raw material, machined Ti surface, about 10%.
