[Ultramicrostructure study of artificial bone composite with high biological induction in repairing bone defect]
1Department of Oral and Maxillofacial Surgery, West China University of Medical Sciences.
Abstract:
The scanning electric microscopy (SEM). X-ray energy graph and Ca, P contents analysis were adopted in studying the mechanism and superiority of two different composite artificial bones (HA-bBMP-Co and HA-Co) to repair segmental bone defect in rabbits. The results indicated that HA-bBMP-Co had a double effects of bone induction and bone conduction. No difference of P content in two weeks after reconstructive surgery was found, but in other periods, there was an obvious difference in Ca and P content between HA-bBMP-Co group and HA-Co group (P < 0.05).
