The purpose of this study was to compare the correlation between the learning effect of dental computer-aided design (CAD) software and computer literacy in the clinical and preclinical experience groups of computer-aided design and computer-aided manufacturing (CAD/CAM).
A total of 28 participants were recruited, including 14 dental students and 14 dental technicians. Their working time was evaluated using a custom abutment design with two dental CAD software program (exocad GmbH and Deltanine). The working time of custom abutment design was measured 3 times. A survey was conducted to evaluate the computer literacy. For statistical analysis, Mann-Whitney U test was used to analyze the difference between the clinical and preclinical experience groups and the correlation between computer literacy and reduction in working time was confirmed by Spearman's Rank correlation analysis (α=.05).
The median working time showed the clinical experience group had faster than the preclinical experience group (P<.001). On the other hand, the reduction in working time was higher in the preclinical experience group (P=.002). Only preclinical experience group had a significant positive correlation between the computer literacy and reduction in working time (P<.001).
Basic computer skills are required for first-time users to achie ve an excellent learning effect of dental CAD software program.
本研究旨在比较牙科计算机辅助设计（CAD）软件学习效果与计算机辅助设计和制造（CAD/CAM）临床和临床前经验组计算机素养的相关性。
共招募了 28 名参与者，包括 14 名牙科学生和 14 名牙科技术人员。使用具有两个牙科 CAD 软件程序（exocad GmbH 和 Deltanine）的定制基台设计来评估他们的工作时间。定制基台设计的工作时间测量了 3 次。进行了一项调查，以评估计算机素养。对于统计分析，使用曼-惠特尼 U 检验分析临床经验组和临床前经验组之间的差异，并通过 Spearman 秩相关分析确认计算机素养与工作时间减少之间的相关性（α=.05）。
中位数工作时间显示临床经验组比临床前经验组更快（P<.001）。另一方面，临床前经验组的工作时间减少更多（P=.002）。只有临床前经验组的计算机素养与工作时间减少之间存在显著正相关（P<.001）。
首次使用牙科 CAD 软件程序的用户需要基本的计算机技能才能获得出色的学习效果。
