ABSTRACT:
A material useful as a biomaterial for the manufacture of prosthetic devices and the like is provided by casting a suitable metal, such a Vitallium, into a hydroxyapatite and/or whitlockite investment with three-dimensional interconnected porosity. The resulting composite is finished to expose the investment in order to provide a superior surface for attachment to bone. The composite may be cast as part of the casting of metal prostheses such as hip joints or artificial teeth, in such a way that the investment is present in a thin layer at the desired bone attachment locations.
