Abstract
Monoblock orthopedic and/or dental implants are disclosed. The monoblock implants include a ceramic articulating surface and an osseointegrative bone-contacting surface. Methods of making such implants also disclosed.
Claims21
A monoblock orthopedic implant, comprising:
- a ceramic substrate comprising an inner bearing surface and a treated outer surface;
- a metallic scaffold adapted for osseointegration bonded to the outer surface;
- and
- a multi-layer construct positioned between the ceramic substrate and the metallic scaffold, the multi-layer construct comprising:
- an inner layer formed of a first material, the inner layer positioned on the treated outer surface;
- an intermediate layer formed of a second material;
- and
- an outer layer formed of a third material, wherein the second material is different from the first material and the third material.

(canceled)
A method for making a monoblock implant having a bearing ceramic surface, the method comprising:
- providing a ceramic substrate having an inner bearing surface and an outer bone-contacting surface;
- treating at least the outer surface of the substrate to provide an oxygen rich surface;
- depositing a first layer of a first metal onto the oxygen rich surface;
- depositing a second layer of a second metal onto the first layer;
- and
- depositing a third layer of the first metal onto the second layer to provide a modified outer surface, wherein the second metal is different from the first metal;
- and
- bonding an osseointegrative scaffold to the modified outer surface, wherein the osseointegrative scaffold comprises a metal foam.
