Processing and properties of hydroxyapatite-based biomaterials for use
as hard tissue replacement implants

This paper reviews past, present and future of the hydroxyapatite (HAp)-based
biomaterials from the point of view of preparation of hard tissue replacement
implants. Properties of the hard tissues are also described. The mechanical
reliability of the pure HAp ceramics is low, therefore it cannot be used
as artificial teeth or bones. For these reasons, various HAp-based composites
have been fabricated, but only the HAp-coated titanium alloys have found
wide application. Among the others, the microstructurally controlled HAp
ceramics such as fibers/whiskers-reinforced HAp, fibrous HAp-reinforced
polymers, or biomimeticallyfabricated HAp/collagen composites seem to be
the most suitable ceramic materials for the future hard tissue replacement
implants.
