摘要： 目的 探讨3D打印模型牙在牙体形态学教学中的应用效果。方法 采用实验对照方法,于2017年9月选取第四军医大学2016级五年制口腔医学专业23名学员为实验组,以2015年9月开始牙体形态学课程的2014级五年制口腔医学专业的22名学员为对照组。实验组采用我院既有的网络课程进行理论课程和石膏牙雕刻实习教学,同时配发全套14颗3D打印模型牙。对照组不配发3D打印模型牙,其余教学方法和实验组相同。教学结束后比较两组学员的考核成绩,并对实验组学员进行问卷调查。结果 实验组学员石膏牙雕刻考核成绩为(87.57±4.55)分,高于对照组学员的(83.18±4.51)分,差异具有统计学意义(P<0.01)。实验组学员问卷调查结果显示,有95.7%(22/23)的学员认为3D打印模型牙对于牙齿形态特征掌握和石膏牙雕刻有较大帮助。结论 3D打印模型牙可以有效帮助学员掌握牙齿解剖形态特征,提高石膏牙雕刻技术。

Abstract: Objective To assess the effect of 3D-printed plastic model teeth in the teaching of dental morphology.Methods Twenty-three undergraduate stomatology students who had matriculated atthe Fourth Medical University in 2016 (course started in September 2017) and twenty-two who had matriculated in 2014 (course started in September 2015) were involved in the study.Each student who matriculated in 2016 was given a full set of 14 standard 3D-printed plastic model teeth for use during the learning process,and an anonymous questionnaire was used to evaluate the 3D-printed plastic model teeth from the perspective of the students.Results For the score of the sculpted gypsum teeth,students who used the 3D-printed plastic model teeth in their studies scored significantly higher (87.57±4.55 vs 83.18±4.51),P<0.01.95.7%(22/23) of the students in 2016 thought that the 3D-printed plastic model teeth were of great help or were very helpful for mastering the anatomy of teeth and for carving the plaster teeth.Conclusions The 3D-printed plastic teeth are of great help to the students in mastering and improving their carving skills.
