  • Deposition of discrete nanoparticles on a nanostructured surface of an implant
    Publication number: 20080220394
    Abstract: A method of forming an implant to be implanted into living bone is disclosed. The method comprises the act of roughening at least a portion of the implant surface to produce a microscale roughened surface. The method further comprises forming a nanoscale roughened surface on the microscale roughened surface. The method further comprises the act of depositing discrete nanoparticles on the nanoscale roughened surface though a one-step process of exposing the roughened surface to a solution including the nanoparticles. The nanoparticles comprise a material having a property that promotes osseointegration.

  • Surface treatment process for implants made of titanium alloy
    Publication number: 20040265780
    Abstract: A titanium 6 A1/4V alloy is provided with a surface topography that is similar to the Osseotite® surface produced on commercially pure titanium. Native oxide is removed from the Ti 6A1/4V alloy, followed by contacting the metal at ambient temperature with an aqueous hydrochloric acid solution containing a relatively small amount of hydrofluoric acid.
