Nanotechnology and Metals Improve Success Rate of Implant Surgery

Recently published nanotechnology research may open up the possibility for medical metal implants to bond with the bodies hard and soft tissues in a manner more akin to nature’s natural bonding process. By chemically etching the surface of titanium, tantalum and chrome-cobalt-molybdenum CrCoMo alloy materials, researchers at the Universite de Montreal have found they can re-create the micro pitting found on the surface of bone. They feel this is the key to developing intelligent materials that are not only easily accepted by the human body but can actively respond to the surrounding biological environment. Experiments found that the body’s existing bone responded more readily to nano etched implants than is currently the case. This opens up the possibility for orthopedic and dental implants to be more rapidly accepted and assimilated in place of original bone, reducing complications and speeding recovery. Another possible application is cardiovascular stents that have anticoagulant properties, which will avoid thrombosis, as well as the capacity to control drug delivery at the implantation site.Researchers stress experiments are currently at the laboratory and the process needs to be further developed but if successful, could further enhance the use of metals in implant applications.–Stuart Burns
