摘要：
A bioactive-type of hydrophilic dental implant which is made of titanium or titanium alloy having a rough surface, wherein a coating layer of a mixed solution comprising i) an organic pH buffering agent and/or inorganic pH buffering agent and ii) an organic amphiphilic having sulfonic group is formed on the rough surface which was pre-treated to remove a contaminant. The present invention has effects preventing that the dental implant is exposed to air before it is inserted into the alveolar bone and the implant surface is re-contaminated improving the biocompatibility of the implant, fluid- and blood-affinity, and the initial osseointegration performance and shortening the osseointegration period, and the surface of the dental implant can be maintained as being hydrophilic for at least 3 years by using a mixed solution of pH buffering agent and organic amphiphilic substance having sulfonic group as a surface coating solution.
