摘　　要：目的:评价数字化虚拟仿真系统用于口腔医学本科生开窗型贴面牙体预备临床前教学的效果。方法:在复旦大学口腔医学院口腔医学23名本科生早接触临床实践教学中,交替应用Simodont虚拟仿真培训系统(以下简称Simodont系统)和仿头模进行贴面牙体预备临床前教学。步骤如下:(1)23名学生接受贴面牙体预备理论知识学习,并完成理论考核;(2)学生被随机分为2组,分别使用Simodont系统和仿头模完成开窗型贴面牙体预备考核,并再次完成理论考核;(3)2组学生交换培训系统,再次完成开窗型贴面牙体预备考核;(4)学生填写调查问卷;(5)收集数据,统计分析。采用21.0软件包对数据进行统计学分析。结果:在评分统计结果中,仿头模培训系统在唇面预备量、唇面整体形态、颈部边缘、邻面边缘评分显著优于Simodont系统(P<0.05)。在培训顺序方面,仿头模优先组唇面预备量评分显著高于虚拟仿真优先组(P<0.05),而虚拟仿真优先组切端长度评分显著高于仿头模优先组(P<0.05)。问卷结果显示,大多数学生认为仿头模在牙体预备量、边缘形态、定深深度和切削力量控制方面优于Simodont系统,而Simodont系统在牙体预备安全性和未来实训发展趋势方面优于仿头模。结论:需要充分考虑数字化虚拟仿真系统的优势和局限性,合理设计教学规划,结合2种培训方法,以提高口腔医学生贴面牙体预备的临床前教学效果。PURPOSE:To evaluate the preclinical teaching effects of digital virtual simulation system applied in window-type veneer tooth preparation of undergraduate dental students.METHODS:In the early clinical exposure of five-year undergraduate students from School of Stomatology,Fudan University,Simodont virtual simulation system and conventional phantom-simulator system were alternatively used in the preclinical teaching of veneer tooth preparation.First,after theoretical training and tests of veneer tooth preparation,twenty-three students were randomly divided into two groups.Students in group of virtual simulation priority were trained using Simodont virtual simulation system,while those in group of phantom priority were trained using traditional phantom head to complete the window-type veneer tooth preparation within the specified time,followed by theoretical test again for all students.Then,the two groups of students exchanged training systems and completed the window-type veneer tooth preparation and assessment in the same time.All students were asked to fill up a teaching questionnaire for the evaluation of two training methods.The data were collected and analyzed using SPSS 21.0 software package.RESULTS:The scores of veneer preparations in labial surface cutting volume,labial surface form,cervical margin design,proximal margin design using traditional phantom head training system were significantly higher than those using Simodont virtual simulation system(P<0.05).Statistical results showed that the scores of labial surface cutting volume of phantom priority group were significantly higher than those of virtual simulation priority group(P<0.05),while the scores of incisal length of virtual simulation priority group were significantly higher than those of phantom priority group(P<0.05).The results of the questionnaire showed that the majority of students believed that the traditional phantom head was more helpful than Simodont virtual simulation in identification of labial surface cutting volume,margin form,depth
