目的

探讨重组人骨形成蛋白-2(rhBMP-2)和胶原基纳米骨复合材料(nHAC)修复牙周骨缺损的效果。

方法

制备小型猪牙周骨缺损模型,设立rhBMP-2-nHAC 复合材料植入组、空白对照组和单纯植入胶原基纳米骨组,术后8 周观察各组间修复效果及组织病理学变化,通过骨组织形态计量学测定分析评价牙周骨组织的再生情况。

结果

术后8 周可见复合材料植入组大量新生牙周组织生长,四环素单标记表面、四环素双标记表面、骨矿化沉积率、骨体积、类骨质表面、成骨细胞表面等骨组织形态计量学结果与空白对照组和单纯胶原基纳米骨组比较,差别均有统计学意义(P <0.05)。

结论

rhBMP-2 和nHAC 可明显促进牙周骨缺损修复。

Objective

To observe and evaluate the effects of recombinant human bone morphogenetic protein-2 (rhBMP-2) and nano-HAP-Collagen (nHAC) on periodontal bone defects repair.

Methods

The rhBMP-2 combined with nHAC were transplanted into man-made periodontal bone defects, and the groups covered with only nHAC or with nothing were the controls. The animals were sacrificed after 8 weeks and the periodontal bone regeneration was observed histologically. Bone histomorphometry was measured.

Results

The rhBMP-2-nHAC group exhibited a large amount of new periodontal tissue. In the bone histomorphometry study,significant differences were found for the STS, DTS, MAR, TBV, TOS and TBOS values among the three groups (P <0.05). The values of rhBMP-2-nHAC and nHAC group were significantly higher than that of the control group (P <0.05). The difference of those value were statistically significant between rhBMP-2-nHAC and nHAC group, too (P < 0.05).

Conclusions

The rhBMP-2-nHAC compound material presents better osteoconductive and osteoinductive activity. It can be used to promote periodontal regeneration.
