| Outline of Final Research Achievements |
Implantable metal frames that had mesh like shapes were formed by means of 3 dimensional direct manufacturing for metal (ARCAM). This equipment is an only one system that can produce 3 dimensional forming for metals using electron beam which enable to make no porosity of target products, eventually could achieved highest mechanical property.
Bone morphogenetic protein was combined on the surface of each 3 dimensional implant, then was implanted in the mouse. At 3 weeks after implantation, new bone formation was observed. When adequate pore size of mesh was formed in the implant, new bone formation was occurred not only on the surface of embedded implant but also inside of the mesh area of the implant. Dextrin showed excellent property as a carrier of recombinant BMP to scaffold. Consequently, the developed system in this project could applicable as a new method for clinical application in dentistry, orthopedics and other medical areas in near future.
