The invention provides novel dental enamel inspired materials for
biomedical and dental applications. The materials are apatite-like
calcium phosphate complexes and may comprise apatite, octacalcium
phosphate crystals, or mixtures thereof. In one embodiment, the materials
(calcium phosphate coatings) are mixtures of crystals of apatite and its
precursor, octacalcium phosphate, nucleated on a titanium surface. They
are prepared using a chemical process leading to the formation of
biological apatite which is similar to that found in natural bone and
teeth. In one embodiment, the materials are prepared by placing a
titanium substrate in a supersaturated calcifyng solution containing
native or purified recombinant amelogenins. The presence of the
amelogenins modulates apatite crystal growth to mimic in vivo apatite
crystal formation. Applications for the materials include, without
limitation, dental tissue (enamel, dentin, cementum) replacement,
orthopeadic implants for bone repair, and coatings for improving the
biocompatibility and bone regeneration capability of currently available
implants or medical devices made of metallic, polymeric, ceramic or
composite materials.
