The use of digital dentistry is rapidly increasing in prosthodontics. However, most dental students are not familiar with applying digital technologies in dental clinics. Thus, the aim of the current study was to assess the perception of dental students at different educational years towards digital impressions in comparison to conventional impressions.
A cross-sectional questionnaire-based study was conducted on various educational years of dental students in the College of Dentistry, Imam Abdulrahman Bin Faisal University, between February and April 2023. The students had performed at least one intraoral scan (Trios 3shape) and another conventional polyether impression for phantom casts/patients. The questionnaire assessed students' perceptions of digital impressions using a 5-point scale ranging from strongly agree to strongly disagree. Mann-Whitney U and Kruskal-Wallis tests were used to compare students' perceptions of digital impressions according to gender and educational year, respectively.
The study included 122 students. About 55% were females with a mean (SD) age = 22.51 (3.36). Most students thought that digital impressions are faster and more user-friendly compared to conventional impressions. Significantly more female students thought that the handpiece was too big for intraoral use (p = 0.04) and that the process of the software was time-consuming and complicated. In general, higher educational year students were more satisfied with the digital impressions than lower educational year students.
Digital impressions were perceived by most students as being faster and easier than conventional ones. However, male students and those with higher educational years showed better perception of digital impression.
数字化牙科在修复学中的应用正在迅速增加。然而，大多数牙科学生并不熟悉在牙科诊所应用数字技术。因此，本研究旨在评估不同年级牙科学生对数字化印模与传统印模的看法。
本研究是在 2023 年 2 月至 4 月期间，在 Imam Abdulrahman Bin Faisal 大学牙科学院的各个年级的牙科学生中进行的一项基于问卷调查的横断面研究。学生们已经进行了至少一次口内扫描（Trios 3shape）和另一次传统聚醚印模用于虚拟模型/患者。问卷使用 5 分制评估学生对数字化印模的看法，范围从非常同意到非常不同意。Mann-Whitney U 和 Kruskal-Wallis 检验分别用于根据性别和年级比较学生对数字化印模的看法。
研究共纳入 122 名学生。约 55%为女性，平均（SD）年龄为 22.51（3.36）。大多数学生认为数字化印模比传统印模更快、更易用。有更多的女学生认为口内使用的手机头太大（p=0.04），软件的过程耗时且复杂。总的来说，高年级学生比低年级学生对数字化印模的满意度更高。
大多数学生认为数字化印模比传统印模更快、更容易，但男学生和高年级学生对数字化印模的看法更好。
