| 摘 要： | 目的:观察聚乳酸材料PLA/PGA在同期植入种植体时的成骨效应及种植效果。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4、8、12周进行X线检查观察成骨情况,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:在所有植入PLA/PGA材料的兔上颌窦都有新鲜成熟骨形成,在同期植入的种植体稳定与新形成骨紧密结合,同时材料本身完全吸收。结论:自体骨复合多孔支架上颌窦提升同期种植体植入具有简便高效易行的优点。

| Abstract: | Objective:To investigate the effect of poly acid (PLA/PGA) as scaffold joint with self bone to produce new bone for implanting at the same time. Methods: Implanting the scaffold PLA/PGA by opened maxillary sinus floor lifting to News land rabbits’ maxillary sinus ,examine the new bone by X-ray 4,8,12 weeks after surgery ,observing the new bone and the effect of implanting by general observation ,microscopy and scanning electron microscopy after sacrificed by the end of 12 weeks. Results:All of the rabbits’ maxillary sinus produced 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. |
