目的：通过对GBR连续组织学研究及放射学检查,探讨几丁质硅胶复合膜在引导性骨再生(guidedboneregenerationGBR)中的作用。
方法：取新西兰兔24只,造成双侧桡骨15mm骨缺损,将48只肢体平均分为A、B、C、D组,每组各12只肢体,分别用几丁质硅胶复合膜、几丁质膜、硅胶管及空白对照。于手术后2、4、6、8、12、16周处死每组各两只兔,标本行X线及组织学检查。
结果：几丁质硅胶复合膜组的骨缺损区在成骨活动的活跃程度、骨再生量和再生髓腔结构等方面均优于单纯几丁质、硅胶管及空白对照组(P<005),使骨缺损得到了修复。
结论：几丁质硅胶复合膜能促进内、外骨痂的生长。 |

Abstract:
Objective:To explore the role of chitin silica gel complex pellicle in the process of guided bone regeneration(GBR) by using continuous histological study and radiological examination
Methods:Bone defects of 15mm on bilateral radius were created in 14 New Zealand rabbits.The 48 limbs were equally divided into 4 groups:A.chitin silica gel complex pellicle group;B.chitin pellicle;C.silica tube and D.control group.Two rabbits in each group were sacrificed at 2nd,4th,6th,8th,12th and 16th weeks after operation and the samples procured at the fracture sites were used for X ray and histological examinations.
Results: The osteoblastic activity,quantity of regenerative bones and regenerative marrow cavity structure in the bone defect region of group A were much better than those of group B,C and D( P<0 05 ).The bone defect was repaired well in group A.
Conclusion:Chitin silica gel complex pellicle might be able to promote growth of interior and external callus. |
