In 14 cases of implants in fresh tooth extraction sites, we filled the gap with baked dental root tips between the site and the implant body.
The Clinical findings were as follows.
1. Intraoral finding is not a problem after operation.
2. Though the tips were large and these margins were sharp, they were small and round after some months, and they were enclosed by connective tissue in the upper part of the gap, and assimilated with bone tissue in the lower part of it.
3. In the X-ray findings, at surgery, though the radiopaque shadow was shown up to the top of the neck of the implant body, the border between the tips and the bone tissue was unclear. After 3～6 months, the radiolucent shadow was slightly shown around the neck of the implant body, but the border was more unclear. After 1～2 years, their shapes were unrecognizable, the top of alveolar bone was flat, and the radiolucent area was slightly shown at the part of implant neck.
4. These results suggest that it is possible to use baked dental root tips for bone replacement material in clinical treatment.
