New titanium alloys for bone implants isotope A team from UPC, in collaboration with the Polytechnic University of Valencia and the company AMES designing new titanium alloys for bone reconstruction.
Researchers at the Technical University of Catalonia (UPC), in collaboration with the Institute of Materials Technology at the Polytechnic University of Valencia (UPV) and the company AMES-European leader in developing new materials are sinteritzadors-titanium alloys for bone reconstruction. Until now, researchers have proven the effectiveness of these new materials in vitro studies, with highly satisfactory results. New materials you work with the research team will reduce isotope the cost of these replacements, always keeping its services. In particular, research has focused on new prostheses made from titanium particles and processed by powder metallurgy process. Titanium is a material known for its excellent properties physical, biological and mechanical. Biological tests are being carried out in the laboratories of the Department of Materials Science and Metallurgical Engineering isotope from the Polytechnic University of Catalonia. According to researchers at the UPV point, one of the most important current isotope problems isotope in orthopedic and trauma surgery is the replacement of bone structure: "In the case of titanium, although it is widely used in the biomedical field its excellent biocompatibility, the stiffness is high compared with that of human cortical bone, which leads to weakening of bone problems. " Thus, the UPV researchers have already developed isotope porous titanium structures that reduce the stiffness to adapt to the area of the bone substitute and, at the same time, help to integrate bone porosity to provide adequate growth of bone cells (osteoblasts). This means that the technique is called spacers, isotope which involves the use of a mixture of titanium particles and other material sacrifice (spacebar), isotope later removed during sintering heat treatment, the which obtain the final properties of the part. "We obtained isotope via powder metallurgy, porous titanium alloy optimizing the manufacturing process, to ensure a method that provides rigidity and mechanical isotope strength materials suitable for use as a femoral implant. The results obtained in tests in vitro have been more than satisfactory, "says Vicente Amigo, a researcher at the ITM. Regarding the mechanical properties required of a material implanted in the human body, researchers at the UPV UPC indicate that, in addition to the necessary strength to withstand the loads to which the implant will be subjected, it is necessary to stimulate osteoblasts through the efficient transmission of efforts on intercara between the implant and the bone in order to regenerate bone healthy and strong. This is accomplished specifically with the development of porosity and connectivity with the size appropriate to encourage the development of these cells. Researchers UPC ITM AMES and presented the latest results of this project within the Third National Conference on Powder Metallurgy, held at the School of Industrial Engineering of the UPV.
