Biologically Active 'Scaffold' May Help Humans Replace Lost Or Missing Bone

Scientist and Professor Meital Zilberman of Tel Aviv University's Department of Biomedical Engineering has developed a new biologically active "scaffold" made from soluble fibers, which may help humans replace lost or missing bone. The invention, which does not yet have a name, could be used to restore missing bone in a limb lost in an accident, or repair receded jawbones necessary to secure dental implants, says Prof. Zilberman. The scaffold can be shaped so the bone will grow into the proper form. They're also specially developed to release bioactive drugs and proteins in a controlled manner. After a period of time, the fibers can be programmed to dissolve, leaving no trace. Her technology also has potential uses in cosmetic surgery. Instead of silicon implants to square the chin or raise cheekbones, the technology can be used to "grow your own" cheekbones or puffy lips. But Prof. Zilberman says it's far too early to think of such uses. She first started her work in biomaterials at the UT Southwestern Medical Center at Dallas, Texas, and currently is concentrating on various medical applications. One of them intends to make dental implants more effective. She envisions applying the invention to organ tissue regeneration in the future. This sounds extremely promising for dental implant treatment! Comments?
