摘　　要：目的介绍一种正畸虚实结合托槽定位训练方法,并探究其教学效果。方法按照随机数字表法将20名2022年3月至12月于四川大学华西口腔医院正畸科学习的硕士研究生分为试验组与对照组,各10名。试验组采用虚实结合托槽定位训练方法教学。对照组采用石膏牙模托槽定位训练方法教学。课程结束后,邀请每名学员利用仿头模在一副牙模上粘接托槽进行考核。获取学员粘接托槽后的数字化牙模并评估托槽定位误差,调查学员对两种训练方法的满意度。结果试验组共计粘接280颗托槽,对照组共计粘接280颗托槽,两组所粘接托槽均未出现脱落。两组近远中向平移误差、合龈向平移误差的绝对值比较,差异无统计学意义(P>0.05),试验组轴倾方旋转误差的绝对值小于对照组(P<0.05)。试验组满意度高于对照组(P<0.05)。结论虚实结合托槽定位训练方法能够帮助学员降低轴倾方向的托槽定位误差,提高学员教学满意度。Objective To introduce a virtual reality combined with orthodontic bracket positioning training method,and to evaluate its teaching effect.Methods Twenty postgraduate students learning at Department of Orthodontics,West China Hospital of Stomatology,Sichuan University from March to December 2022 were divided into experimental and control group according to the random number table method,with 10 students in each group.The experimental group was taught by the virtual reality combined with orthodontic bracket positioning training method.The control group was taught by the plaster model bracket positioning training method.After the training,each student in both groups was asked to bond brackets on a dental model in a dental mannequin for examination.The digital models of the dentitions bonded with brackets by the students were acquired and the brackets’positions were evaluated,and the students were investigated for the satisfaction for the two training methods.Results A total of 280 brackets were bonded by the experimental group,and a total of 280 brackets were bonded by the control group.No bracket bonding failure was found in any of the two groups.There was no significant difference between the two groups in the absolute values of proximal and distal translation error(P>0.05),and the absolute values of axial tilt rotation error in the experimental group were smaller than those in the control group(P<0.05).The satisfaction of the students in the experimental group was significantly higher than that of the control group(P<0.05).Conclusion The virtual reality combined bracket positioning method can help the students reduce the error in positioning the brackets in the angulation and improve the students’satisfaction for the teaching.
