Abstract
A bone grafting material is derived from allogenic or xenogenic bone by a process that includes tanning with glutaraldehyde. The bone may be pulverized, used as a large block, or machined into a precise pre-determined shape, depending on the bone defect to be repaired. Glutaraldehyde tanning of bone yields a stabilized, highly biocompatible, and non-antigenic material which becomes incorporated into host bone when placed adjacent to it.
