| Research Abstract |
The purpose of this study is to clarify the mechanism of osteons formation and regeneration that has never been studied and in vivo osteons formation and regeneration mechanism using novel biomaterials technologies. Therefore, we establish the in situ bone regeneration techniques to induce maturation bone matrix formation that was difficult until now. Thus, we examined the utility of cortical bone induced artificial bone with the addition of growth factors or cytokines by using the experimental dog (Beagle) model which found osteons structure in the same as human.
Furthermore, we prepared in situ regenerative bone tissue, which placed in a new absorbable mesh tray cortical bone induced artificial bone, and implanted in beagle bone defect model to verify their usefulness.
