Implant prosthesis and method for producing same
First Claim
1. An implant prosthesis produced by the steps of:
- (a) providing a substrate of ceramic material;
(b) coating the substrate with a thin glass layer, the thin glass layer defining a surface remote from the substrate;
(c) roughening the surface of the thin glass layer remote from the substrate;
(d) thermally spraying a layer of calcium phosphate-based material on the roughened surface of said glass layer; and
(e) firing said layer of calcium phosphate based material at a temperature in the range of 600°
to 1100°

Abstract
An implant prosthesis comprising implant substrate of ceramic material, a thin glass layer coated over the adhering interface of the substrate relative at least to a bone, and a thermally sprayed layer of calcium phosphate based material formed over the glass layer.
The implant provides excellent adhesion of the thermally sprayed layer of calcium phosphate based material to the substrate, with ensuring advantages of stabilized implantation in a living body in that the thin glass layer between the substrate and the calcium phosphate based material removes fear of the sprayed material coming off and/or falling off the substrate or possibility of bringing about reduced strength of the substrate.
