摘要： 目的 对比顺时针调拌法与顺时针联合八字形调拌法对藻酸盐印模精确性的影响。方法 选取2018年3月—4月上海市浦东新区周浦医院口腔科固定单冠烤瓷牙修复病例40例,由2名护士与同一名医生对40例单冠烤瓷牙修复患者分别用2种调拌方式取制2套模型,分为实验组和对照组。对照组使用顺时针手工调拌方法制取模型,实验组使用顺时针联合八字形手工调拌方法制取模型。采用SPSS 24.0软件包对数据进行Mann-Whitney秩和检验。结果 由同一名高年资技师使用放大镜对制备的印模进行观察,记录肩台印迹、龈沟翼及气泡产生情况,综合评价印模质量。2组间比较差异有统计学意义（Z=-4.634,P<0.001）。其中,顺时针联合八字形调拌法印模质量Ⅰ级优秀比例（77.5%）显著高于顺时针调拌法（10%）,Ⅳ级不合格比例（2.5%）显著低于顺时针调拌法（27.5%）。结论 使用顺时针联合八字形调拌法的印模质量显著高于顺时针调拌法,提高了取模的成功率,减少了重复印模给患者带来的不适。该技术的推广,有利于促进护理隐性知识的传播。

Abstract: PURPOSE: The effect of clockwise mixing method and clockwise combined eight-shaped mixing method on the accuracy of alginate impression was compared. METHODS: From march to April 2018, 40 dental restoration cases in the Department of Stomatology, Zhoupu Hospital, Pudong District, Shanghai were selected. Two nurses and the same doctor treated 40 patients with single crown porcelain restoration. Two sets of models were taken by two kinds of mixing methods, which were divided into experimental group and control group. Clockwise manual mixing method was used in the control group to take the model, while clockwise combined eight-shaped mixing method was used in the experimental group to take the model. SPSS 24.0 software package was used for Mann-Whitney rank sum test. RESULTS: The same high-grade technician used a magnifying glass to observe the prepared impression, recorded the shoulder print, the sulcus wing and bubble generation, and comprehensively evaluated the impression quality. A comparison was made between the two groups, Z=-4.634, P<0.001, and the difference was statistically significant. Among them, the ratio of excellent quality of the clockwise combined eight-shaped mixing method (77.5%) was significantly higher than that of the clockwise mixing method (10%), and the proportion of level IV unqualification (2.5%) was significantly lower than that of the clockwise mixing method (27.5%). CONCLUSIONS: The quality of impression using clockwise combined eight-shaped mixing method is higher than that of the clockwise method, which improves the success rate of the mold and reduces the discomfort caused by repeated impression. Application of this technique is helpful to the promotion of occult knowledge among nurses.
