| Research Abstract |
Implantation of a nHAC membrane that was loaded with low dose of BMP-2 and placed on dentin chips, into rat thigh muscle, resulted in the formation of a long thin, cementum-like hard tissue on the dentin surface at an early stage after implantation without increasing dentin resorption. On the other hand, the nHAC, cross-linked by EDC and added fibrin glue has more elastic. This new material showed a good biocompatibility and biodegradability in vivo. nHAC-fibrin composite with BMP-2 resulted in ectopic bone formation in rat thigh muscle, and showed to be suitable as the carrier of BMP-2.
