Abstract 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.
