摘要

目的　探索3D打印前牙区牙周骨缺损模型联合案例导向教学法（case-based learning，CBL）在重度牙周病松牙固定术规培教学中的效果。方法　纳入口腔全科住院医师规培生60人为研究对象，分为两组，每组30人；其中CBL组接受CBL教学，3D+CBL组采用3D打印前牙区牙周骨缺损模型联合CBL教学。教学结束后，教师对规培生理论和实践成绩进行考核，并设计调查问卷评估规培生松牙固定术学习的教学效果。采用SPSS 16.0软件进行统计学分析，两组间的比较采用t检验。结果　相较于CBL组，3D+CBL组理论成绩（89.0±3.2）和实践成绩（90.0±2.5）均高于CBL组理论成绩（83.3±3.6）和实践成绩（84.2±3.5）（P＜0.05）。调查问卷结果显示，3D+CBL组规培生在牙周基础知识的掌握、松牙固定术专业知识的掌握、病例诊断及制订治疗计划的能力、临床操作能力、教学内容趣味性、与带教教师沟通意愿、主动接诊患者的意识、规培满意度八个方面均高于CBL组（P＜0.05）。结论　3D打印前牙区牙周骨缺损模型联合CBL的教学在松牙固定术教学中获得较好的效果，为3D打印模具在前牙松牙固定术临床教学中的应用提供了参考

Abstract

Objective　To explore the effect of 3D printing periodontal bone defect model of anterior teeth combined with case-based learning (CBL) teaching mode in the standardized residency training of loose teeth fixation. Methods　Sixty general practitioner of stomatology students were equally divided into two groups

with one group receiving CBL teaching (CBL group) and the other group receiving 3D printing model combined CBL teaching (3D+CBL group). After the teaching

the teacher evaluated the overall practice effects

tested the residents' theory and practice scores

and designed a questionnaire to evaluate the teaching effect. SPSS 16.0 software was used for statistical analysis

and t test was used for comparison between the two groups. Results　The theoretical score (89.0±3.2) and the practical score (90.0±2.5) in the 3D+CBL group were significantly higher than the theoretical score (83.3±3.6) and the practical score (84.2±3.5) in the CBL group (P<0.05). The questionnaire showed that the students of the 3D+CBL group performed significantly better than those in CBL group in the following eight aspects

including mastery of basic periodontal knowledge

professional knowledge of loose teeth fixation

ability to diagnose cases and formulate treatment plans

clinical operation ability

interesting teaching content

willingness to communicate with teachers

awareness of actively receiving patients

and satisfaction of standardized residency training (P<0.05). Conclusion　The 3D printing periodontal bone defect model of anterior teeth combined with the CBL teaching mode has achieved good results in the teaching of loose teeth fixation

and it provides a reference for the application of 3D printing in clinical teaching for periodontology.
