虚拟模型外科在正颌外科线上教学中的应用

Application of virtual model surgery in online teaching of orthognathic surgery

目的探索虚拟模型外科在口腔专业本科生正颌外科线上教学中的应用价值。方法选取2020年5月至11月90名口腔专业本科生为研究对象,将其随机分为A组(30例,PPT理论教学)、B组(30例,数字化理论教学)和C组(30例,数字化实验教学)。采用课后测验及Likert量表问卷评价三组学生的教学效果。结果三组学生的课后测验、问卷调查评分比较,差异具有统计学意义(F=29.448、74.004,P<0.001);A组的课后测验、问卷调查评分低于B组、C组,差异具有统计学意义(P<0.001);B组、C组的课后测验、问卷调查评分比较,差异无统计学意义(P>0.05)。结论将数字化正颌虚拟手术系统引入到本科生的线上教学中是对本科生培养方式的一种有效改进,有益于本科生对正颌外科学的理解,使得线上教学工作朝着更科学、合理的方向发展。

Objective To explore the application value of virtual model surgery in online teaching of orthognathic surgery for undergraduates majoring in stomatology.Methods A total of 90 undergraduate students majoring in stomatology from May to November 2020 were selected as the study objects and randomly divided into group A(30 cases,PPT theoretical teaching),group B(30 cases,digital theoretical teaching)and group C(30 cases,digital experimental teaching).The after-school test and Likert scale questionnaire were used to evaluate the teaching effect of the three groups of students.Results There were significant differences in the scores of after-school tests and questionnaire survey among the three groups(F=29.448,74.004,P<0.001);the scores of after-school test and questionnaire survey in the group A were lower than those in the group B and the group C,and the differences were statistically significant(P<0.001);there were no significant differences in the scores of after-school test and questionnaire survey between the group B and the group C(P>0.05).Conclusion Introducing the digital orthognathic virtual surgery system into the online teaching of undergraduates is an effective improvement of the undergraduate training method,which is beneficial to the undergraduates'understanding of orthognathic surgery and makes the online teaching work develop in a more scientific and reasonable direction.
