Porous titanium foam dental implants (a prototype is shown) being developed by NRC scientists will improve the way we replace lost of damaged teeth. Traditional dental implants are solid pieces of titanium, a biocompatible metal. The implant is surgically inserted into the jaw bone and capped with a ceramic tooth. However, the proprietary NRC titanium foam has a porous structure similar to that of bone. The pores provide a site for bone cells to grow into the implant and thus more solidly anchor it. This will facilitate faster healing and the use of smaller implants.
