目的：分析3M纳米树脂在牙齿修复的临床效果。方法：于2014 年1 月到2014年9 月，选取我院患者90 例，360 颗患牙，随机分为3M纳米复合树脂组、光固化复合树脂组、玻璃离子水门汀组，观察术后患者的满意度、临床疗效。结果：在术后即时，三组之间的患者满意度上的差异无统计学意义；在术后1 年后，3M纳米复合树脂组的患者满意度高（89.66 %）于光固化复合树脂组（78.57 %）和玻璃离子水门汀组（68.97 %）（P<0.05）；在临床疗效方面，3M纳米复合树脂组成功率为93.10%，远高于光固化复合树脂组（75.00 %）、玻璃离子水门汀组（68.97 %），组间差异具有统计学意义（P<0.05）；而光固化复合树脂组和玻璃离子水门汀组之间患者满意度和临床疗效上的差异无统计学意义（P>0.05）。结论：3M纳米树脂治疗在牙齿修复中具有良好的美观性和理想的临床疗效。

英文摘要:

Objective:To analyze the clinical effect of 3M nano resin on dental restoration.Methods:90 patients with defect of teeth who were admitted to our hospital fromJanuary to September 2014 were selected and randomly divided into three groups: the group of 3M nano resin group, the Light-cured composite resin group and the Glass ion cement group. The patients' satisfaction and clinical curative effect in the three groups were compared after operation.Results:After operation, there was no statistical differences among three groups at aspect of patients' satisfaction; One year after operation, patients' degree of satisfaction in group of 3M nano resin was 89.66 %, higher than the groups of Light-cured composite resin (78.57 %) and Glass ion cement (68.97 %) (P<0.05); At aspect of clinical curative effect, the success rate of the group of 3Mnano resin was 93.10%, higher than that of the groups of Light-cured composite resin (75.00 %) and Glass ion cement (68.97 %) and and its difference was statistically significant (P<0.05); However, there was no statistical differences between the groups of Light-cured composite resin and Glass ion cement at aspect of patients' satisfaction and clinical curative effect (P>0.05).Conclusion:The aesthetics and clinical curative effect on dental restoration were good with the material of 3M nano-resin.
