分步教学法在数字化种植导板设计培训中的应用

Application of Step-by-step Teaching Method in the Training of Digital Implant Guide Design

目的:应用分步教学法进行数字化种植导板设计的培训并评估其效果。方法:选取2020~2021年滨州医学院附属烟台口腔医院临床实习口腔医学技术班50名学生为研究对象。按照随机数字表法分为实验组和对照组,各25名,实验组采用分步法教学,对照组采用整体教学法。教学结束后,由两组学生和5名授课教师分别进行教学评价。由第三方同行专家从建立订单数据导入、配准三维重建、虚拟三维排牙、种植体三维设计、导板设计生成5个方面分别打分,通过单项分和总分评价设计效果。结果:实验组分步教学法及对照组整体教学法的学生评分分别为(4.44±0.58)、(3.48±0.59),教师的评分分别为(4.52±0.51)、(3.28±0.54),第三方同行专家评分的综合评分分别为(8.32±0.64)、(7.48±0.65),种植体三维设计单项评分分别为(1.60±0.50)、(1.24±0.44),导板设计生成单项评分分别为(1.88±0.33)、(1.32±0.69),差异均具有统计学意义(P<0.05)。结论:分步教学法可以提高种植导板设计培训效果,学生和教师的接受度更高。

Objective:To evaluate the effect of applying the step-by-step teaching method in the training of implant guide design.Methods:50 students of stomatological technology class in Yantai Stomatological Hospital of Binzhou Medical University,were recruited in this study.They were randomly divided into the experimental group(n=25)and the control group(n=25).The experimental group was taught in the step-by-step method,and the control group was taught in the traditional teaching method.Thereafter,the assessments were done by the students and teachers.The quality of design was evaluated by the third-party peer experts from the establishment of data,the registration of three-dimensional reconstruction,the alignment of virtual dental crown,the design of implant’s three-dimensional position and the generation of guide,respectively.The scores of each aspect and the total were taken together as the outcome.Results:For the outcome of the experimental group and the control group,the students’assessments were(4.44±0.58)and(3.48±0.59),the teachers’assessments were(4.52±0.51)and(3.28±0.54).The total scores of the design effect evaluated by the thirdparty peer experts were(8.32±0.64)and(7.48±0.65).The scores of the design of implant’s three-dimensional position were(1.60±0.50)and(1.24±0.44),and the scores of the generation of guide were(1.88±0.33)and(1.32±0.69).The differences were statistically significant(P<0.05).Conclusions:The step-by-step teaching method could improve the training effect of implant guide design,and the acceptance of students and teachers was higher.
