Abstract

Abstract: PURPOSE: To compare the application value of three cephalometric teaching modes(digital software tracing, traditional manual tracing, and the combination of these two methods) in the practical teaching of orthodontic-orthognathic combined treatment. METHODS: A total of 18 undergraduate students majoring in stomatology who practiced at the 2nd Dental Center, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from September 2022 to September 2023 were selected and randomly divided into 3 groups with 6 students in each group. Students in the three groups were taught Steiner cephalometric analysis using the Dolphin digital cephalometric software (the digital group), the traditional manual tracing method(the traditional group), and the combined method of the two approaches(the combined group), respectively. A 4-week intensive teaching and training program was carried out. Assessments were conducted at the end of the 2nd week and upon the completion of the training. The effects of different teaching methods were evaluated by comparing the differences between the measured values obtained by the students and the standard values. RESULTS: All students completed the course, with a 100% qualification rate of the experimental reports. After 2 weeks of training, the combined group showed significantly lower differences in core measurement items including SNA, SNB, ANB, U1-SN, U1-L1 and MP-SN compared with the traditional group and digital group(P<0.05). After 4 weeks of training, there were no significant differences in the deviations of all measurement items among the three groups. CONCLUSIONS: The combination of digital software and traditional methods can achieve favorable teaching effects in cephalometric teaching for combined orthodontic and orthognathic treatment. It provides more experience for the digital teaching of combined orthodontic and orthognathic treatment, and also offers a reference for the inheritance of traditional methods, which is worthy of further improvement and popularization.
