目的

评估数字化效果模拟器在口腔正畸临床教学中的应用效果。

方法

选取2020—2021年于中山大学附属口腔医院正畸科就诊的安氏Ⅰ类、安氏Ⅱ类和安氏Ⅲ类错畸形病例共6个,完善问诊、临床检查和X线片检查后,提供相应的石膏模型和数字化模型。中山大学光华口腔医学院口腔正畸学专业的2018 ~ 2021级研究生28人通过分层随机抽样法分为两组(每组14人),分别进行传统的石膏模型排牙预测(A组)和数字化效果模拟器预测(B组),并完成正畸诊断和治疗计划。由具有硕士生导师资格的3位教师对其诊断和治疗计划进行评估,同时讲授其依据。两组学生分别对传统石膏排牙预测和数字化效果模拟器预测过程进行评价。

结果

在"制定方案主动性"和"考虑牙移动细节"方面,B组学生得分高于A组,差异具有统计学意义(P<0.001)。相比于A组,B组中更多学生认为数字化模拟器可提高学习兴趣(A组78.57%、B组100%)、加深对诊断与治疗计划的理解(A组75.00%、B组89.28%)和考虑更多三维牙移动(A组64.28%、B组75.00%)。在教师评价中,B组在治疗计划讲授过程得分高于A组(P<0.001)。

结论

数字化效果模拟器可锻炼学生的临床思维能力,提高口腔正畸诊断与治疗计划的制定的教学效果。

Objective

To evaluate the effect of outcome simulator in the clinical teaching of orthodontics.

Methods

Six typical malocclusion cases, derived from patients treated in Department of Orthodontics Hospital of Stomatology during 2020 to 2021, including Angle ClassⅠ, Angle ClassⅡ and Class Ⅲ malocclusion were selected. All clinical materials including contented consultation, clinical examination, X-ray analysis, plaster models and digital models were provided. 28 graduated students (grade 2019 to 2021) majoring in Orthodontics, Guanghua School of Stomatology, Sun Yat-sen University, were divided into two groups (Group A and Group B) by stratified random sampling. The students performed tooth arrangement on traditional plaster model (Group A) or outcome simulator (Group B) respectively, and then made diagnostic analysis and treatment plans. The diagnosis analysis and treatment plans from Group A and Group B were evaluated by 3 teachers (postgraduate tutors) and the explanations are given as well. The students and teachers conducted self-evaluation after undergoing different teaching methods.

Results

Students in Group B got higher scores in "Initiative of making treatment plans" and "Consider more tooth movement details" compared to students in Group A (P<0.001) . The ratios of agreement in "promoting interests in study" (78.57% in group A, 100% in group B) , "easier to understand treatment plans" (75% in group A, 89.28% in group B) and "more consideration of 3D tooth movement" (64.28% in group A, 75.00% in group B) in Group B were higher than Group A. Moreover, the teaching efficiency was higher in Group B compared to Group A (P<0.001) , rating by the teachers.

Conclusion

The outcome simulator can help build up students’ logical thinking power in clinical work and improve the teaching effect of making diagnosis and clinical treatment plans for orthodontics.
