Fast Integration Treatment (FIT), a New Nanostructured Titanium Carbide Based Film, that Reduces more than 50 the Osseointegration Time of Surgical Implants

摘要

The use of titanium surgical prosthesis for dental and orthopaedic implants is continuously growing, mainly because the aging of the population of industrial ized countries. A drawback of these surgical operations resides in the long period necessary to reach a complete osseointegration and, than, to charge the prosthesis. This paper describes the biological results obtained with a new treatments (patent pending) realized by Pulsed Laser Ablation Deposition PLAD and Ion Plating Plasma Assisted IPPA vacuum deposition, evaluated both "in vitro" and "in vivo" and the compositional characteristics of the deposited nanostructured film. The tests performed, also with real dental prosthesis, implanted into rabbit legs, show an improvement in the osseointegration activity that induces to expect a reduction better than 50% in the "time to charge" in human bones. The treatment acts also as protection of the titanium prosthesis from the aggressive attacks of biological fluids and tissues;The IPPA treatment represents an evolution of a previous one, based on Pulsed Laser Ablation Deposition, that is not suitable for a real industrial production on 3D shaped substrates. Some details of the IPPA deposition process and the methods of biological characterizations are also reported.
