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 the act of immersing the microscale roughened surface into a solution containing hydrogen peroxide and a basic solution to produce a nanoscale roughened surface consisting of nanopitting superimposed on the microscale roughened surface. The nanoscale roughened surface has a property that promotes osseointegration.
Claims19
A method of forming an implant to be implanted into living bone, the method comprising:
- acid etching at least a portion of the implant surface to produce a microscale roughened surface;
- and
- treating the microscale roughened surface to provide a nanoscale topography superimposed on the microscale roughened surface, wherein treating the microscale roughened surface to include the nanoscale topography includes immersing the implant in a solution including hydrogen peroxide and a basic solution.
A method of forming an implant to be implanted into living bone, the method comprising:
- roughening at least a portion of the implant surface to produce a dual microscale roughened surface including a first microscale surface having first peak-to-valley distances and a second microscale surface superimposed on the first microscale surface, the second microscale surface having second peak-to-valley distances that are less than the first peak-to-valley distances;
- and
- treating the dual microscale roughened surface to provide a nanoscale topography superimposed on the dual microscale roughened surface.
