TLDR
An implantable prosthesis anchorage which contains a non-porous outer coating in the regions which are positioned in contact with bone is described in this paper, where the ceramic material is in particulate form having particle diameters between 0.5 and 1 mm.Abstract:
An implantable prosthesis anchorage which contains a non-porous outer coating in the regions which is positioned in contact with bone. The non-porous outer coating consists of (i) at least one bioactive resorbable ceramic material which is a calcium phosphate and (ii) at least one polymer which is mechanically and chemically stable in the body. The ceramic material is in particulate form having particle diameters between 0.5 and 1 mm. The ceramic material particles is incorporated in the polymer in such a way that resorption of the ceramic material leads to a polymer structure with continuous pores filled with living bone tissue. Bioactivating bonding residues of the ceramic material are left on the inner surfaces of the filled pores which were created by the resorption of the ceramic material.read more

Sputtering of bone on prostheses
Bevil J Shaw,Richard P Miller +1 more
TL;DR: In this paper, a system of coating prostheses with ground bone particles is presented, where prostheses made of various metals and other substances are coated using rf sputtering techniques to form a film which adheres to the device, stimulates living bone attachment thereto and which is ultimately replaced by new bone.
