| Outline of Final Research Achievements |
The purpose of this researh was to develop and apply feasible and less invasive surgical treatments for maxillofacial boney defects using novel bioactive and bioresorbale scaffold materials of uHA/PDLLA composite for bone regeneration therapy in combination use of priosteal derived osteogenic progenitor cells. In vitro study, we elucidated the osteogenic cells could induce cell viablitity, growth and osteogenic differentiation in this novel scaffold showing the feasibility as a maxillofacial boney regenerative scaffold material. Further, in vivo study, we developed an animal model of critical boney defect with a diameter of 4mm in mandible using a rat. Then we grafted this scaffold materials into boney defects. The morphological and histomorphological studies obtained in this study showed this novel scaffold might induce bioactive function of osteogenic activity inducing bone regeneration. Also the periosteal derived osteogenic cells might further induce bone regenerative effects.
