Fixing teeth permanently.

Fixing teeth permanently

Teeth, it has been said, are the first things to rot in living people and the last things to rot after death. Finding replacements in living people hasn't been easy: Gum ridges that serve as seats for dentures tend to wear down, and permanent implants often break down over time. Mayo Clinic researchers in Rochester, Minn., are among several U.S. groups evaluating a technique devised at the University of Goteborg in Sweden. In the process, permanent implants are attached with titanium and gold fixtures into which the jawbone grows. After two years 98 percent of the fixtures remain stable in the 70 patients studied, they report in the February issue of MAYO CLINIC PROCEEDINGS.
