Abstract:

Objective To compare the clinical effect on dental implant with minimally invasive flapless surgery of immediate implantation in maxillary anterior zone.Methods Sixty patients were divided into observation group and control group. The observation group was given with flapless surgery during immediate implant, the control group used traditional flap surgery immediate implant. The patients were followed up 3, 6, 12 months and compared the pink aesthetic index、alveolar bone absorption level and the satisfaction index.Results The pink aesthetic index was significantly higher than that in control group in 3, 6 and 12 month (P<0.05). At the same time, the satisfaction index (87%) was also significantly higher than that in control group (74%). The alveolar bone absorption were lower than that in control group (P<0.05).Conclusion Flapless surgery of anterior maxillary teeth immediate implant can better improve the effect of both soft and hard tissue which also meets the needs of patients. Such method is worthy of recommendation.

摘要：

目的 观察常规翻瓣种植与不翻瓣种植在前牙即刻种植修复中的临床效果。方法 60例患者随机分成2组,试验组30例,采用不翻瓣方式行即刻种植术,对照组30例,采用常规翻瓣即刻种植术。记录2组修复后3、6、12个月的红色美学指数、牙槽骨吸收水平及满意度。结果 修复后3个月（t = 5.585）、6个月（t = 6.740）、12个月（t = 10.933）,试验组红色美学指数高于对照组（P<0.05）;修复后12个月试验组患者满意度（87%）高于对照组（74%）（χ ² = 1.667,P = 0.197）;修复后3个月（t = 6.360）、6个月（t = 14.112）、12个月（t = 11.553）,牙槽骨吸收水平较对照组低（P<0.05）。 结论 前牙即刻种植采用不翻瓣技术与常规翻瓣技术比较,可提高临床修复效果和患者的满意度。
