Title : Functional surface films for individual reconstructive implant in maxillofacial surgery

Abstract:

Trauma, disorders, oncology in head and neck organs have growing level . Actually to make reconstructive technologies for restoration this main region of human body. But metals and alloys meet many of these requirements, and the bond strength between the implant and the bone is insufficient. One of the effective ways to initiate the formation of a bone-like layer on the surface of the implant is to cover it with a bioactive multifunctional coating. We to performed innovative trial for manufacturing additive reconstructive implants for maxillofacial surgery. TiC 0.5+10%(Ca10(PO4)6(OH) were synthesized composite targets using the combined forces SHS-pressing technology. The targets were subjected to magnetron sputtering in a mixture of argon and nitrogen. The diameter of the target was 125 mm, the distance from the substrate to the target was 100 mm. The total pressure P was maintained at 0.2 Pa, the partial pressure of nitrogen was 14% of the total pressure.
Ti-Ca-P-C-O-N coatings with a thickness of 0.7-0.8 µm were deposited on titanium medical grids. During the deposition process, the substrate temperature was maintained at 2000C. The total deposition time of the coatings was 60-90 minutes. MBNPS possessed a unique combination of chemical, mechanical and tribological properties. Especially - low coefficient of friction in physiological media 0.12-0.25. After this implants performed in biomedical experience and clinic trial.  Clinic stage showed better results than pure titanium implants .
