摘要 目的利用种植型牵张器增高兔下颌牙槽嵴,观察牵张成骨过程中金葡液的作用,并探讨其可能的作用机制。方法 40只兔建模后随机分为实验组和对照组2组,每组20只。术后第8天开始,实验组局部注射金葡液,对照组不加药。术后不同时间分别行大体观察、X线观察、组织学观察、免疫组化观察和灰度值测定并进行统计学分析,测定血清钙、磷及碱性磷酸酶(ALP)含量。结果实验组术后不同时间的骨代谢活性、新骨生成和血清钙、磷及ALP含量均高于对照组。牵张后1d、1周、2周、四周,实验组和对照组免疫组化染色平均灰度值间差异有统计学意义。结论在兔下颌骨牵张成骨时,局部注射金葡液可以达到良好的骨再生,加速牵张过程中新骨生成,从而缩短骨愈合时间。
