| Outline of Final Research Achievements |
Recently, artificial bone having high biocompatibility have already been developed and applied to bone tissue reconstruction. However at present, there has been no less invasive and secure method for large defect of bone tissue on head and neck nor craniofacial surgery. In this study, we investigated osteogenetic ability of honeycomb β-TCP with through hole on rat histologically, and adequate osteogenesis was recognized depending on size of hole diameter. This honeycomb β-TCP which was transplanted to total bone defect on zygomatic bone of rat showed sufficient union at a cut end part of zygomatic bone on micro CT image. These results suggest that honeycomb β-TCP can be excellent biomaterial for reconstruction of hard tissue on facial area.
