[Scanning electronic microscope (SCM) examination of the hydroxylapatite (HA) combined with bone morphogenetic protein (BMP) implanted on the bone surface].
HA combined with BMP was implanted on the surface of rabbit's parietal bone and examined with SCM. The results indicate that there are a large amount of new bone formation within the combined material and the amount is increasing as the time lapsed. The new bone is directly connected with the HA particles, forming a bony interface between the host bone and the implants to integrate them. In contrast, there are a lot of fibrous tissues with a little new bone formed on the interface if HA is implanted alone. The result implies that the BMP plays a very important role in new bone formation and the combined material is ideal for alveolar ridge augmentation.
