Use of nanomaterials based on titanium dioxide and zirconium diozide as coatings for osteointegrated biomedical prostheses, and osteointegrated biomedical prostheses prepared therewith

摘要

Materials and methods, for preparation of coatings based on titanium dioxide for osteointegrated biomedical prostheses. The coatings may comprise nanomaterials having antibacterial properties. For example, an endo-osseous implant is provided with a coating comprised of nanocrystalline material comprising nanoparticles of formula (I) (L-Men+)i,  (I) where AOx represents TiO2 or ZrO2; Men+ is a metallic ion having antibacterial activity, with n=1 or 2; L is a bi functional organic molecule which can simultaneously bind to the metal oxide and to the metallic ion Men+, and i is the number of L-Men+ groups bound to one nanoparticle of AOx.
