| Outline of Final Research Achievements |
In cases where teeth are lost, maintenance of the denture and adaptation of the implant becomes difficult because the bone mass of the jaw decreases. Therefore, as a treatment after tooth extraction aiming at preventing reduction of bone mass, and also to increase bone mass, we investigated the effects of compression hemostasis by gauze after extraction and coral filling material implantation on bone. Immediately after removing the left molar of the mandibular bone of the Beagle dog, it was compressed by gauze, coral implantation was used as an experimental group, and right molar that was not pressed was used as a control. After implantation, the mandible was removed. Mandibular bone was measured bone density with X-ray and histological observation of new bone formation by confocal laser scanning microscope. Although there was no effect of compression by gauze on bone mass on this time, using bone filling agent by coral had the effect of bone augmentation.
