Deposition of discrete nanoparticles on a nanostructured surface of an implant

摘要

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.

1. A method of forming an implant to be implanted into living bone, the method comprising the acts of:
forming a microscale roughened surface on at least a portion of the implant surface; forming a first nanotopography on the microscale roughened surface; and depositing a second nanotopography on portions of the first nanotopography, wherein a portion of the first nanotopography is exposed through the second nanotopography such that the exposed portion of the first nanotopography is for contacting bone.
