客观的自我评估是必不可少的学习和继续在牙科能力。计算机辅助设计/计算机辅助制造（CAD/CAM）学习软件（prepCheck，Sirona）允许学生客观地评估他们在临床前修复学中的表现。本研究的目的是评估学生的认知CAD/CAM学习软件的临床前口腔修复练习。2014年，哈佛牙科医学院的所有三年级牙科学生（n=36）都由经过培训的教师单独指导使用prepCheck。每位学生完成了金属陶瓷冠制备的临床前形成练习（#18）和总结性考试（#30），并在prepCheck中使用五种评估工具（缩小、边缘宽度、表面光洁度、锥度和底切）对制备进行了评价。然后，学生们对这五种工具的有用性、用户友好性和使用频率进行评分，评分范围从1=最低到5=最高。教师将牙齿准备分为通过（P），边缘通过（MP）或失败（F）。调查答复率为100%。用于底切和锥度的工具在有用性、用户友好性和使用频率方面得分最高。在所有类别中，复位工具评分均显著降低（p
Objective self-assessment is essential to learning and continued competence in dentistry. A computer-assisted design/computer-assisted manufacturing (CAD/CAM) learning software (prepCheck, Sirona) allows students to objectively assess their performance in preclinical prosthodontics. The aim of this study was to evaluate students' perceptions of CAD/CAM learning software for preclinical prosthodontics exercises. In 2014, all third-year dental students at Harvard School of Dental Medicine (n=36) were individually instructed by a trained faculty member in using prepCheck. Each student completed a preclinical formative exercise (#18) and summative examination (#30) for ceramometal crown preparation and evaluated the preparation using five assessment tools (reduction, margin width, surface finish, taper, and undercut) in prepCheck. The students then rated each of the five tools for usefulness, user-friendliness, and frequency of use on a scale from 1=lowest to 5=highest. Faculty members graded the tooth preparations as pass (P), marginal-pass (MP), or fail (F). The survey response rate was 100%. The tools for undercut and taper had the highest scores for usefulness, user-friendliness, and frequency of use. The reduction tool score was significantly lower in all categories (p
