| Research Abstract |
In this study, in order to evaluate the usefulness of Zr70Ni16Cu6Al8 bulk metallic glasses(Zr-BMG) as a mini-screw for the orthodontic treatment, we analyzed from biological viewpoint. As a result, since bone-marrow mesenchymal cells on the Zr-BMG have the potential of focal adhesion, proliferation and osteogenic differentiation when cultured by osteogenic induction medium in vitro, it became clear that Zr-BMG have good biocompatibility. And more, we transplanted the Zr-BMG into the rat maxillary jaw. No inflammatory responses were seen in vivo.
