摘　　要：目的:评价可摘局部义齿质量量表的临床应用效果。方法:设计可摘局部义齿质量量表。在基托人工牙、卡环支托、连接体和调改4个方面设立12项条目,内容包括修复体目测评分和初戴评分,分A、B、C 3个级别。将4家义齿加工单位随机分为实验组和对照组,2组均用单盲法评分,实验组知晓量表,课题组定期向其管理部门反馈评分情况并作医-技电话交流,对照组不作反馈。对比2组修复体质量评分。采用SPSS17.0软件包对数据进行统计学分析。结果:实验组在基托人工牙、卡环支托、连接体和调改4个方面的评分均高于对照组,经方差分析,有统计学意义(P<0.01)。实验组在树脂基托义齿、隐形义齿和铸造支架义齿的A级分别为27.2%、39.5%和40.6%,C级分别为9.2%、7.9%和7.2%,B级为大多数。对照组A级分别为9.4%、15.6%和15.0%,C级分别为40.6%、23.6%和25.0%,B级为多数,C级比例较高,经χ2检验,2组有显著差异。结论:可摘局部义齿质量量表的临床应用可提高修复体制作质量。PURPOSE： To evaluate the effects of quality scale for removable partial dentures （RPD）in clinical application. METHODS： Quality scale for removable partial dentures was designed. Twelve items were devised for visual survey and try-in in base, artificial teeth, clasp, rest, connector and adjustment. The assessments were divided into 3 grades A, B and C. Four commercial dental laboratories were divided into experimental group and control group randomly. All RPD made in two groups were given score with the quality scale by single-blind method. In the experimental group , the technicians were familiar with the quality scale. The assessments were periodically feedbacked to administrative staffs and exchanges were carded out between doctors and technicians by telephone. No feedback information was provided in the control group. The assessments were compared between the two groups. The data was analyzed with SPSS17.0 software package. RESULTS： The scores of assessments for base, artificial teeth, clasp, rest, connector and adjustment in the experimental group were greater than that in the control group. The difference was significant between the two groups by analysis of variance （/9〈0.01）. The grade A and C for RPD used acrylic resin, flexible resin and cast framework in the experimental group was 27.2%,39.5%,40.6% and 9.2%, 7.9%,7.2%, respectively. The grade B was in the majority. In the control group, the grade A and C was 9.4%,15.6%,15% and 40.6%,23.6%,25%,respectively. The majority was grade B and the grade C was significantly higher than the experimental group （P〈0.05）. CONCLUSION： Applying the quality scale of RPD can improve the fabricating quality of prosthesis.Supported by Research Fund of Science and Technology Commission of Zhabei District and Bureau of Health, Shanghai Municipality （2010 general 07）.
