Abstract
A coated implant includes a coating comprising a doped hydroxyapatite portion and an undoped hydroxyapatite portion. The coated implant can be formed by treating a hydroxyapatite coating with a solution comprising a dopant metal.
Claims20
A coated implant comprising,
- a substrate having a bone-facing surface, and
- a doped coating located on the bone-facing surface of the substrate,
- wherein the doped coating comprises calcium and a dopant metal, and
- wherein the concentration of the dopant metal is anisotropic in the doped coating.

A process for forming a coated implant, the process comprising
- contacting a hydroxyapatite coating on a substrate with an aqueous solution comprising a dopant metal ion, and
- washing the hydroxyapatite coating after the step of contacting to form a doped hydroxyapatite coating comprising calcium and a dopant metal,
- wherein the concentration of the dopant metal is anisotropic in the doped hydroxyapatite coating.
A coated implant comprising,
- a substrate, and
- a coating located on a surface of the substrate,
- wherein the coating includes a doped hydroxyapatite portion and an undoped hydroxyapatite portion located between the doped hydroxyapatite portion and the substrate, and
- wherein the doped hydroxyapatite portion comprises calcium and a dopant metal.
