Abstract
A method including forming a first coating layer derived from an alkoxide on a substrate having a dimension suitable for an implant and forming a second coating layer on the first coating layer that promotes osseointegration. An apparatus comprising a substrate having a dimension suitable as a medical or dental implant and a coating on a surface of a first coating layer derived from an alkoxide and a second coating layer that promotes osseointegration.
Claims27
A method comprising:
- forming a first coating layer from a condensation reaction of an alkoxide, the first coating layer comprising a ligand comprising a positively charged moiety on a substrate having a dimension suitable for an implant;
- and
- applying a second coating on the first coating layer, the second coating comprising a hydroxyapatite material having a property that promotes osseointegration.
An apparatus comprising:
- a substrate having a dimension suitable as a medical or dental implant;
- and
- a coating on a surface of the substrate, the coating comprising a first, coating layer derived from a condensation reaction of an alkoxide having a ligand comprising a positively charged moiety and a different second coating layer on the first coating layer and comprising hydroxyapatite particles.
