3D打印技术在颌骨肿瘤与肿瘤样变临床教学中的应用

Application of 3D printing technology in clinical teaching about jaw bones tumor and tumor-like lesions

目的探讨3D打印技术应用于颌骨肿瘤与肿瘤样变临床教学中的效果。方法将参与颌骨肿瘤与肿瘤样变课程的92名学生随机分成2组进行对比教学。第一组先进行以知识点讲解、病例分析及锥形束CT检查等为主的传统教学,再进行3D打印技术辅助的新方法教学;第二组先行3D打印技术辅助的新方法教学,再进行传统教学。分别对两组学生两学时后的教学情况进行问卷调查及对比,评估3D打印技术辅助的教学新方法对颌骨肿瘤与肿瘤样变临床教学的相关作用。结果传统教学方法对于颌骨肿瘤与肿瘤样变基础解剖知识点的掌握更有优势(P<0.05);对于肿瘤细节、知识记忆、肿瘤空间形态、教学生动性等方面,3D打印技术辅助的教学新方法更有优势(P<0.05)。教学顺序对最终学习效果影响较小,但牵涉到知识记忆和空间形态的理解方面,让学生先行3D打印技术辅助教学的新课程再行传统课程得分更高(P<0.05)。结论先进行3D打印技术辅助的教学新方法在一定程度上更有利于让学生从三维空间上去理解和掌握肿瘤与肿瘤样变的特点。

Objective To explore the effect of 3 D printing technology applying into clinical teaching about jaw bones tumor and tumor-like lesions.Methods In order to proceed the contrastive teaching experiment,we divided 92 students who participated in the jaw bones tumor and tumor-like lesions class into 2 groups randomly.Students in group 1 took traditional teaching method including the basics of knowledge,case analysis and CBCT test at the first period.After that,they took new teaching method assisted by 3 D printing technology at the second period.Students in group 2 were taught in reverse order by the same teacher.The questionnaire survey was conducted after each period in each group so as to evaluate the role new teaching method assisted by 3 D printing technology played in the jaw bones tumor and tumor-like lesions clinical teaching.Results The questionnaire surveys showed that traditional teaching method predominated in the students’grasp of basic knowledge about jaw bones tumor and tumor-like lesions(P<0.05).With regard to showing the details and spatial forms of lesions as well as teaching vividly,new teaching method assisted by 3 D printing technologywas better than the traditional one(P<0.05).The order didn’t concern a lot about the final learning effectiveness.However,when it came to the memorizing of knowledge and the understanding of lesions’spatial forms,students who took the new teaching method first had higher average scores(P<0.05).Conclusions To some extent,carrying on new teaching method assisted by 3 D printing technology first among the class may leads students to a better understanding and mastering about the anatomic features of jaw bones tumor and tumor-like lesions.
