[An experimental study of the tissue compatibility of titanium implants coated with hydroxyapatite and aluminum oxide by plasma spraying].

The reaction of bone tissue to implantation of cylindric titanium implants sprayed with hydroxyapatite and aluminum oxide was studied. The coating was characterized by a high biological histocompatibility. The elements of cellular reactions specific for foreign bodies were absent, this permitting us to refer such coating to bioactive materials. The strength of fixation in the bone was compatible to the strength of osseous tissue adjacent to bone tissue implant. The coating may be used in oral implantology, traumatology, and orthodontics.
