摘要
目的:通过动物实验观察同期种植体与多孔支架植入后种植体与骨组织的结合状况来为临床应用提供依据。方法:将预制成形的PLA/PGA材料,通过上颌窦提升术植入新西兰兔的上颌窦中,同期植入钛种植体,术后12周全部处死通过大体、组织学及电镜观察成骨及种植效果。结果:12周后肉眼可见所有种植体顶端周围多孔支架均形成骨组织且与新骨结合紧密牢固:扫描电镜和透射电镜均证实新生骨组织与种植体结合紧密。结论:种植时在骨质不足的条件下,可以通过同期植入种植体和多孔支架来同时完成新骨形成及其二者的结合,种植体与新生骨结合牢固,方法有效效果可靠。
Objective：Investigate the interface between implant and new bone which formed from of poly acid（PLA/PGA） as scaffold embedded with implant at same time.Methods：Implanting the scaffold PLA/PGA by opened maxillary sinus floor lifting to News land rabbits＇ maxillary sinus,implanting at the same time,examine the new bone,observing the new bone and the effect of implanting by observing、 microscopy and scanning electron microscopy after sacrificed by the end of 12 weeks.Results：All of the rabbits＇ maxillary sinus produce the new mature bone,it bond with the dental solidly with the scaffold absorbed thoroughly.Conclusion：The method that this experiment applied can settle the implant problem of none enough bone effectively.
