DENTAL IMPLANT COATED WITH A MIXED SOLUTION OF CHEMICAL BUFFERING AGENT AND ORGANIC AMPHIPHILIC SUBSTANCE AND A PREPARATION PROCESS THEREOF

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.

主权项

1. A bioactive-type of hydrophilic dental implant which is made of titanium or titanium alloy having a rough surface, characterized in that 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 substance having sulfonic group is formed on said rough surface which was pre-treated so as to remove a contaminant, wherein said organic pH buffering agent has 8.0 or more of pKa, and is at least one or more selected from AMPD, ammonia, bicine, glycine, glycyiglycine, tris, tricine and taurine; and said inorganic pH buffering agent is characterized in that it has hydroxyl group and is at least one or more selected from NaOH, KOH, Ca(OH)2, Ba(OH)2, Al(OH)3 and Sr(OH)2.
