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 roughened surface. The method further comprises the act of depositing discrete nanoparticles on the roughened surface though a one-step process of exposing the roughened surface to a solution. The nanoparticles comprise a material having a property that promotes osseointegration.

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.

International Classification:

A61F 2/02

US Classification:

433173, 4332011, 623 2355

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.

International Classification:

B05D 3/00
A61K 6/00
A61L 27/30

US Classification:

427 227, 427 226

Abstract:

A method of increasing the hydrophilicity of an implant to be implanted into living bone. The method comprises the act of depositing non-toxic salt residuals on the surface of the implant by exposing the surface to a solution including the non-toxic salts. The method further comprises the act of drying the implant.

International Classification:

A61L 33/00
B05D 3/00

US Classification:

427 212, 4332011

Abstract:

A method of forming a nanocrystalline surface on an implant. The method includes the act of roughening at least a portion of the implant surface to form a roughened surface. The method further includes the act of, without forming an alkoxide on the roughened surface, depositing nanocrystals on the roughened surface. The nanocrystals include a material having a property that promotes osseointegration.

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.
