Outline of Final Research Achievements

In dental bone regeneration field, many bone substitutes were developed and studied, though, there are no bone substitutes, which have comparable remodeling ability with native host bone. Our department developed Hydroxyapatite Fiber (HA fiber), and it could demonstrate bone augmentation and healing ability.
In this research, we applied HA fiber with Magnesium, pointed as important factor for bone remodeling. With this modification, we expect ‘’precipitative bone regeneration ability’’ for HA fiber. Our research for this new Magnesium modified HA fiber (Mg mod HA fiber) were planned on in vitro and in vivo study. In vivo study demonstrated that Mg mod HA fiber enhance osteogenic gene expression. In vitro study demonstrated that Mg mod HA fiber enhance bone formation. We concluded that Magnesium modification for HA fiber was effective for bone formation.
