Antibacterial coatings on titanium implants

J Biomed Mater Res B Appl Biomater. 2009 Oct;91(1):470-80. doi: 10.1002/jbm.b.31463.


Titanium and titanium alloys are key biomedical materials because of their good biocompatibility and mechanical properties. Nevertheless, infection on and around titanium implants still remains a problem which is usually difficult to treat and may lead to eventual implant removal. As a result, preventive measures are necessary to mitigate implant-frelated infection. One important strategy is to render the implant surface antibacterial by impeding the formation of a biofilm. A number of approaches have been proposed for this purpose and they are reviewed in this article.
