1. A method of forming an implant to be implanted into living bone, the method comprising the acts of:
- roughening at least a portion of the implant surface to produce a first topography;
further roughening the implant surface to produce a second topography superimposed on the first topography; and
providing a nanoscale topography superimposed on the first and second topographies.

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.

21. A method of forming an implant to be implanted into living bone, the method comprising the acts of:
-
grit blasting at least the portion of the implant surface to produce a first roughened surface including peak-to-valley heights of about 10 microns to about 30 microns; acid etching the grit blasted surface to produce a second roughened surface having peak-to-valley heights of less than about 10 microns superimposed on the first roughened surface; and providing a nanoscale topography superimposed on the second roughened surface. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
