Researchers at Medical College of Georgia have introduced a new technology to treat the tooth loss due to gum disease, that would embed specialized proteins onto dental implants to stimulate native stem cells to differentiate and become bone-forming cells thereby contributing to bone-regenerating implants. Researchers say: Titanium dental implants coated with proteins that induce bone formation may be a key advancement in treating tooth loss due to gum disease. Dr. Wikesj says: There was almost complete regeneration. The generated bone bonded with the implant’s surface and, eventually, existing bone in the gums. That allowed for the regeneration of gum tissues.
The technology has come a long way as some researchers in Finland have developed a machine which they claim to have the capability to manufacture human spare parts. Well, not exactly the human parts but in actual a tactic that enables fabrication of nano and micrometer scale structures that can be used as parts of tissue engineering scaffolds. So, they are not making human parts but the synthetic human tissues. I am impressed! Via: blog.sci.fi
