Notes:
Percutaneous type of orthopedic and dental implants requires not only a good adhesionwith bone, but also the ability to form good attachment and seal with connective tissues and skins.Currently, the skin-seal of such implants still remains as a problem to be resolved.Electrochemical processing was used to modify the surface of titanium implants in order to improvethe ability of anti-bacteria infection and skin seal around the implants by synthesizing a fluoridatedcalcium phosphate thin film on titanium substrate. The surface of titanium was cathodically treatedin an electrochemical cell. A thin film of about 80 nm thickness was deposited on the titaniumsurface by controlling the treatment parameters. The dense and gel-like film was composed ofcalcium phosphate and fluorine ions. Fluorine ion has the anti-bacteria property and could help toimprove the skin seal around the percutaneous device. The electrochemical method of fluoridatedcalcium phosphate thin film synthesis will provide an alternative method for surface treatment oforthopedic and dental implants
