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。
Objective: To evaluate the clinical effect of the removable partial denture mass scale. Methods: Design removable partial denture mass scale. In the base of artificial teeth, card ring support, connectors and changes in the four aspects of the establishment of 12 items, including the restoration of physical evaluation score and initial wear score, points A, B, C three levels. The four denture processing units were randomly divided into experimental group and control group, both groups were scored by single-blind method, and the experimental group was aware of the scale. The research group regularly reported the score to its management department and made medical and technical telephone exchanges. The control group No feedback. Comparison of two groups of prosthesis quality score. SPSS17.0 software package for statistical analysis of the data. Results: The scores of experimental group were higher than that of control group in four aspects: artificial denture, acetabular ring abutment, connector and adjustment. The variance analysis showed statistically significant (P <0.01). The experimental group had 27.2%, 39.5% and 40.6% A grade in the resin-based denture, stealth denture and casting stent denture, respectively, the C grade was 9.2%, 7.9% and 7.2%, respectively. In the control group, the A level was 9.4%, 15.6% and 15.0% respectively. The C level was 40.6%, 23.6% and 25.0% respectively. The B level was the majority and the C level was higher. Conclusion: The clinical application of removable partial denture mass scale can improve the quality of prosthesis.
