电热熔模器在口腔固定修复工艺学实验教学中的应用

Application of electric heating pattern instrument in experimental teaching of fixed partial den- ture technology

目的探讨电热熔模器在口腔固定修复工艺学实验教学中的应用效果。方法选取2008级和2009级口腔修复工艺专业本科生98人为研究对象。其中2008级学生46人作为对照组，采用酒精灯加热的滴蜡器熔化嵌体蜡，完成固定义齿蜡熔模制作；2009级学生52人为实验组，采用电热熔模器熔化嵌体蜡，完成固定义齿蜡熔模制作。通过学生实验考试成绩和问卷调查评估教学效果。结果实验组成绩为（25．5±2．1）分，对照组成绩为（22．6±1．8）分，差异有统计学意义（P〈0．05）。学生的问卷调查结果表明，实验组较对照组满意度更高。结论在口腔固定修复工艺学实验教学中应用电热熔模器制作蜡熔模，操作方便，能显著提高蜡熔模的制作质量和工作效率，增强学生学习的信心，值得推广。

Objective To discuss the effects of applying electric heating pattern instrument in experimental teaching of fixed partial denture technology. Methods Totally 98 prosthodontic under graduates of 2008 and 2009 grades were selected in this study; 46 students of 2008 grade were taken as control group and 52 students of 2009 grade were taken as experimental group. Students in experimental group made wax patterns with electric heating pattern instruments to melt inlay wax while those in con- trol group made wax patterns with instruments heated by alcohol lamps. Teaching effects were evaluated by experimental test scores and questionnaires. Results Test scores of experimental group were （22. 6 ± 1.8 ）, obviously higher than those of （22.6 -± 1.8 ） in control group （ P 〈 0.05 ）. Satisfaction degree of experimental group were increased significantly compared with that of control group based on the re- sults of questionnaire. Conclusions Applying electric heating pattem instrument in making wax pat- terns in experimental teaching of fixed partial denture technology is easy to operate and can improve the quality of wax pattern and working efficiency as well as enhance students＇ confidence, therefore it is worthy further spreading.
