磨牙竖直模型在口腔正畸学实验教学中的应用

目的:通过磨牙竖直模型在口腔医学本科教学中的应用,探索改革口腔正畸学有关固定矫治技术的实验教学方法。方法:在皖南医学院2009级口腔医学专业学生中随机选择两个小班(各30人)分别设为实验组和对照组。实验组进行磨牙竖直实验,对照组进行常规固定矫治器的实验。对托槽的粘贴、矫治弓丝的弯制和作用及运用、牙齿移动及移动类型、支抗的认识、辅助正畸的了解以及学习兴趣等几方面进行了问卷调查并进行统计学分析。结果:实验组在对矫治弓丝作用及运用、支抗的理解、牙齿移动及移动类型以及对辅助性正畸的认识与对照组的差别有统计学意义,在托槽的粘贴、弓丝的弯制以及对正畸学的学习兴趣方面的差别没有统计学意义。结论:口腔正畸学固定矫治技术的实验教学中运用磨牙竖直模型训练学生能够更好地让学生理解和掌握支抗、矫治弓丝的运用、牙齿的移动、牙齿移动的种类以及辅助性正畸治疗。

Applying molar uprighting model to experimental orthodontics practice

Objective：To explore a strategy to improve the experimental teaching of orthodontics for undergraduate students on the fixed molar uprighting model basis.Methods：Two small-sized classes（students enrolled in 2009 in Wannan Medical College） were randomly included and allocated to experi-mental group and control group（n=30 for each）.The experimental group were taught with molar uprighting model and the controls with conventional fix appliance.By the end of the curriculum,two groups of students were surveyed with questionnaire concerning the requirements specified in the program ob-jective including the skills of pasting brackets and archwire bending ,understating of the role of archwire in tooth movement and type of tooth movement , knowledge of anchorage and importance of adjunctive orthodontic treatment as well as the interest of orthodontics learning ,and the results were statistically analyzed.Results：The two groups were statistically different regarding the understanding of the role of archwire and its application ,knowledge of the an-chorage,the tooth movement and the movement type as well as importance of adjunctive orthodontic treatment ,yet remained not so significant on the skills of pasteing bracket and archwire bending besides learning interest in orthodontics .Conclusion：Application of molar uprighing model may benefit the students in learning orthodontics on commanding of the skills defined in the curriculum .
