17 Claims

1. A method of depositing nanoparticles on a dental implant comprising:

preparing an electrolyte solution comprising an aqueous solution having silver nitrate (AgNO₃) and sodium nitrate (NaNO₃), wherein the aqueous solution has a concentration of between about 0.01 mM to about 50 mM, inclusive, AgNO₃, and wherein the aqueous solution has a concentration of between about 138 mM to about 1000 mM, inclusive, NaNO₃;

positioning the dental implant within the electrolyte solution;

applying an electric current to the electrolyte solution for a duration of time, thereby causing deposition of silver nanoparticles on a surface of the dental implant, the silver nanoparticles providing antimicrobial properties to the dental implant;

rinsing the dental implant with deposited silver nanoparticles; and

drying the dental implant with deposited silver nanoparticles in an oven between about 95° C. to about 105° C., inclusive for a period of time between about 20 minutes to about 40 minutes, inclusive.
