3M Z350XT纳米树脂和Keer Premisa通用纳米树脂修复前牙牙体缺损的疗效比较

Comparison of clinical curative effect in restore anterior tooth defects:using two different resins

目的:比较3M Z350XT纳米树脂和Keer Premisa通用纳米树脂修复前牙牙体缺损的临床效果。方法:364颗因龋坏或外伤造成牙体缺损需要进行修复的前牙随机分为两组,分别采用Z350XT树脂和Premisa树脂充填修复,并在修复后即刻、6个月、1年参考美国公共卫生署(USPHS)修复体临床评价标准对口内充填体进行临床评价。结果:两组在修复即刻检查评价,成功率均达到100%。6个月后随访,两组的成功率差异没有统计学意义(P>0.05)。1年后随访,两组成功率比较,Z350XT组明显高于Premisa组(P<0.05)。结论:Z350XT树脂用于前牙缺损修复的成功率较高,修复效果可靠。

Objective To observe the clinical curative effect of using 3M Z350XT resin and Keer Premisa resin in restore anterior tooth defects. Methods 364 anterior teeth that needed to be restored were divided into two groups randomly.One group was treated with 3M Z350XT resin compostite,the other was treated with Keer Premisa resin compostite.All the restorations were evaluated in oral cavity after 6 months and 1 year finlling with United State public health service criterions. Results In clinical service for 6 months, the successful rate was 100% in the two groups.There was no statistically significant difference （P〉0.05）. Conclusion In clinical service for lyear,3M Z350XT resin is much better than Keer Premisa resin,the difference being statistically significant（P〈0.05）.
