文题释义：
Dentistry-ProConsult软件：是一款移动终端App，由奥古斯塔州立大学研发，适用于IOS系统，该软件可提供正常人群牙齿形态的3D模型和不同角度的牙齿咬合关系，同时可立体、动态、真实的显示在咬合和咀嚼过程中对应牙齿的相对位置及复杂的受力情况，便于学生掌握抽象的牙齿咬合关系。
石膏牙造模：学员在初步了解牙体解剖形态理论知识的基础上，用石膏雕刻刀在石膏牙上进行雕刻，形成立体的牙体形态，在雕刻的过程中进一步加深对牙体形态的理论知识的理解，并锻炼动手能力，为日后口腔临床操作打下基础。
 
 
背景：在口腔医学教学实践中，牙列的正常形态及咬合关系一直是教学的难点，但牙齿的咬合界面及功能耦联关系复杂，不易掌握，一直以来也是临床教学的难点和重点。
目的：探索Dentistry-ProConsult软件辅助石膏牙造模在口腔教学中的应用效果。
方法：将44名空军军医大学五年制口腔医学专业本科四年级学员随机分为2组，对照组(n=21)在传统教学模式下学习不同类型牙齿的解剖结构和咬合关系及雕刻蜡牙，无任何功能软件的应用；试验组(n=23)在Dentistry-ProConsult软件辅助石膏牙造模口腔教学模式下学习不同类型牙齿的解剖结构和咬合关系，通过Dentistry-ProConsult软件辅助石膏牙造模口腔教学，带教教师可主动引导学生通过三维模型从不同层次和角度理解牙齿的正常形态及复杂的咬合关系，在此基础上结合3D打印模型，让学员在石膏模具中逐一雕刻正常牙齿形态。学期末对学员的笔试成绩及操作成绩进行统计学分析。
结果与结论：①试验组理论成绩高于对照组[(85.6±12.4)，(79.3±15.7)分，t=6.735，P < 0.05]，操作考试成绩高于对照组[(88.2±10.6)，(82.5±14.5)分，t=7.182，P < 0.05]；②问卷调查显示，试验组学员对于该课程的教学满意程度评分优于对照组[(87.5±8.7)，(79.7±10.1)分，t=8.531，P < 0.05]；③结果表明，Dentistry- ProConsult软件辅助石膏牙造模教学方法显著提高了学员的理论及实践成绩，同时提高了学员的课堂满意度。

Abstract:

BACKGROUND: In the practice of stomatology teaching, the normal morphology of teeth and their occlusal relationship are always a difficult point in stomatology teaching. However, the occlusal relationship of teeth and their functional coupling are complicated and difficult to understand and are always the difficult point and focus of clinical teaching.
OBJECTIVE: To investigate the application of Dentistry-ProConsult software to assist plaster tooth modeling in stomatology teaching.
METHODS: Forty-four undergraduate students of five-year oral medicine major from the Air Force Medical University were randomly divided into two groups. In the control group (n=21), traditional teaching method was used to learn the anatomic structure and occlusion of different types of teeth and engrave wax teeth. In the experimental group (n=23), Dentistry-ProConsult software was used to learn the anatomic structure and occlusion of different types of teeth and to model plaster teeth. The teachers could guide students to learn the normal morphology of teeth and their occlusal relationship from different angles with the Dentistry-ProConsult software. In addition, the students were asked to carve the normal morphology of teeth in plaster model with the aid of 3D models. The theoretic and practicing test scores were compared between the control and experimental groups.
RESULTS AND CONCLUSION: The theoretic (85.6±12.4 vs. 79.3±15.7) and practicing test scores (88.2±10.6 vs. 82.5±14.5) in the experimental group were significantly higher than those in the control group (t=6.735 for theoretic test, t=7.182 for practicing test, P < 0.05). The feedback questionnaires showed that the satisfaction rate in the experimental group (87.5±8.7) was significantly higher than that in the traditional teaching group (79.7±10.1, t=8.531, P < 0.05). These results showed that application of Dentistry-ProConsult in the stomatology teaching greatly enhanced student’s theoretic and practicing test scores and increases student’s degree of satisfaction in stomatology teaching.
