1、应用膜引导技术即刻种植牙对骨修复影响[摘要]目的探讨膜引导技术在即刻种植牙中的临床疗效,以及对患者骨修复的影响。方法选择浙江省台州市温岭第三人民医院即刻种植牙患者38例(种植牙体52枚)作为研究对象,观察患者的临床疗效以及对不同方法测量计算成骨率进行比较。结果52颗牙钛膜平均保留时间为3.2个月,种植体稳定,所有切口均为甲级愈合,随访两年,患者种植体周围骨的吸收高度平均为(1.31±0.17)mm,未出现松动情况;平均骨厚度测量结果:直接测量法为(2.20±0.27)mm,CT二维测量法为(2.27±0.30)m
2、m,两种方法经相关性分析呈显著正相关(r=0.9994,P0.05)o结论膜引导技术运用于即刻种植中,能够获得良好的骨修复,CT三维重建能够对种植效果进行客观准确的评价,同时还能够为术前的方案设计提供参考,值得在牙种植中推广使用。[关键词]膜引导技术;即刻种植牙;骨修复[中图分类号]R782.12[文献标识码]C[文章编号]1673-7210(2013)11(c)-0166-03Theeffectsofguidedboneregeneration-membranetechniqueonbonerepairinim
