First Claim
Patent Images
1. A method of treatment, repair, or replacement of human or animal bone, comprising:
- (a) preparing a semiconductor porous and/or polycrystalline silicon and a carrier material to form a silicon composite material such that at least part of the silicon is in contact with at least part of the carrier material;
(b) implanting the silicon composite material; and
(c) allowing the bone to bond to the silicon composite material;
wherein the silicon and carrier material have a structure and composition such that at least part of the silicon induces bioactivity in at least part of the carrier material.

2. A method of treatment, repair, or replacement of human or animal bone, comprising:
-
(a) preparing a semiconductor porous and/or polycrystalline silicon and a resorbable carrier material to form a silicon composite material such that at least part of the silicon is in contact with at least part of the carrier material; (b) implanting the silicon composite material; and (c) allowing the bone to bond to the silicon composite material; wherein the carrier material has a structure and composition such that it is resorbable and wherein the silicon and resorbable carrier material have a structure and composition such that at least part of the silicon induces bioactivity in at least part of the carrier material.
