摘要:

背景:Bio-oss的颗粒状结构通常应用于洞形缺损的充填性移植,对于三壁以上的缺损修复难以成形。
目的:评价Bio-oss以纤维蛋白胶复合骨形态发生蛋白2作为赋形材料后的成骨性能。
方法:拔除9条杂种犬双侧下颌第2,4前臼齿及第2臼齿,造成1 cm×1 cm的骨缺损区,将Bio-oss+纤维蛋白胶+骨形态发生蛋白2、Bio-oss+纤维蛋白胶及Bio-oss材料分别植入第2,4前臼齿及第2臼齿骨缺损区。
结果与结论:各组软组织均一期愈合。Bio-oss复合纤维蛋白胶后,骨粉结合紧密,不易剥离。术后4,8,12周时 Bio-oss+纤维蛋白胶+骨形态发生蛋白2组新生骨百分率均高于其他两组(P < 0.05)。表明纤维蛋白胶的加入可以解决Bio-oss成形困难的问题,骨形态发生蛋白2的加入可促进成骨效果。

Abstract:

BACKGROUND: Bio-oss granular structure is normally used for hole-shaped defects in the form of filling transplantation, but it is difficult to forming for more than three-wall defects.
OBJECTIVE: To evaluate the osteogenic activities of Bio-oss after combination with fibrin glue and bone morphogenetic protein-2 in the repair of canine mandibular defects.
METHODS: The second and fourth premolar teeth and the second molar teeth were extracted bilaterally in nine hybrid canines, resulting in 1 cm × 1 cm bone defect. Bio-oss, Bio-oss+fibrin glue and Bio-oss+fibrin glue+bone morphogenetic protein-2 were implanted into bone defects of the second, fourth premolar teeth and the second molar teeth, respectively.
RESULTS AND CONCLUSION: Stage Ⅰ healing of soft tissues was achieved in all animals. Bio-oss was closely combined with fibrin glue, which was difficult to be separated. The proportion of new bone was higher in the Bio-oss+fibrin glue+bone morphogenetic protein-2 group than in the other two groups at 4, 8, and 12 weeks after extraction (P < 0.05). It shows that fibrin glue can solve the difficulty in Bio-oss formation, and Bio-oss combined with bone morphogenetic protein-2 can promote osteogenic activities.
