引导性骨再生技术在前牙美学区即刻种植和延期种植中的临床疗效研究

摘要

目的：探讨GBR（引导性骨再生）技术在前牙美学区不同的种植时间（即刻种植和延期种植）的临床疗效。方法：随机选取应用GBR技术行前牙修复的患者69例（69牙），分为即刻种植27例和延期种植42例两组，所有患者均于二期术后18个月复查，记录分析两组的种植成功率、成骨效果（包括成骨生长与骨性结合）及美学效果（采用红色白色美学标准PES-WES评分）。结果：术后18个月，即刻种植组和延期种植组种植成功率分别为96.30%和97.62%，两组比较差异无统计学意义（P>0.05）；两组的成骨效果（包括成骨生长与骨性结合）比较差异均无统计学意义（P>0.05）；即刻种植组的红色美学指数（PES）与白色美学指数（WES）均高于延期种植组，两组比较差异均有统计学意义（P<0.05）。结论：在前牙美学区应用GBR技术时，种植时机不影响术后18个月的种植成功率及成骨效果，但即刻种植的美学效果高于延期种植。%Objective:To investigate the clinical efficacy of membrane guided bone regeneration (GBR) technique in immediate implants and delayed implant for anterior teeth aesthetic region.Method:69 teeth of 69 patients who received treatment for anterior teeth restoration with GBR technique were selected and randomly divided into two groups,immediate implant group for 27 cases and delayed implant group for 42 cases. After the second phase of surgery at 18 months, the success rate of implants, osteogenic effect(included osteogenesis grow and bony union)and aestheticeffect (assessed using pink esthetic scores PES and white esthetic score WES)of all patients were observed.Result: 18 months after operation, the success rate of implants in immediate implant group was 96.30% and the delayed implant group was 97.62% ,the difference was not statistically significant(P>0.05);compared the osteogenic effect(included osteogenesis grow and bony union)of two groups, the differences were not statistically significant(P>0.05);the score of PES and WES in immediate implant group were apparently higher than these in delayed implant group,the differences were statistically significant(P<0.05).Conclusion: In the predental aesthetic area,the planting time is not affected by the success rate of 18 months after the operation, but the aesthetic effect of immediate implantation is higher than that of GBR.
