Digitalization is assuming increasing significance in dental education, as dental students are increasingly exposed to digital implant planning and contemporary technologies such as 3D printing. In this study, we present a cohort analysis aimed at assessing the potential benefits derived from the utilization of 3D prints to seamlessly translate planned procedures into real-life applications.
21 dental students participated in a virtual planning and hands-on course across two cohorts (C1: n = 10, C2: n = 11). The virtual implant planning phase involved the placement of four implants on an atrophic lower jaw model. Subsequently, Cohort 1 (C1) executed the implantation procedure on a prefabricated hands-on model, while Cohort 2 (C2) engaged with 3D prints representing their individual implant planning during the hands-on session. Subjective assessments of knowledge, skills, and the perceived utility of 3D prints were conducted through pre- and post-course questionnaires, utilizing a 5-point scale.
In the subjective evaluation, 17 out of 21 participants expressed a positive appraisal of the use of personalized models. Notably, there was no statistically significant improvement in overall knowledge scores; however, there was a discernible increase of 0.5 points in the ratings related to perceived expertise and procedural abilities.
While there was a notable increase in the subjective ratings of knowledge and abilities, no statistically significant difference was observed between the two groups. The consensus among dental students is that individually planned and printed implant models serve as a valuable and effective tool in hands-on courses.
数字化在牙科教育中变得越来越重要,因为牙科学生越来越多地接触到数字化种植体规划和当代技术,如 3D 打印。在这项研究中,我们进行了一项队列分析,旨在评估利用 3D 打印将计划的手术无缝转化为实际应用的潜在益处。
21 名牙科学生分两个队列(C1:n=10,C2:n=11)参加了虚拟规划和实践课程。虚拟种植体规划阶段涉及在上颌骨模型上放置四颗种植体。随后,C1 组(C1)在上预制的实践模型上执行种植手术,而 C2 组(C2)在实践课程中使用代表其个人种植体规划的 3D 打印模型。通过课前和课后问卷,利用 5 分制对知识、技能和对 3D 打印的感知效用进行主观评估。
在主观评估中,21 名参与者中有 17 名对个性化模型的使用表示肯定。值得注意的是,总体知识得分没有显著提高;然而,在感知专业知识和手术能力方面的评分却提高了 0.5 分。
虽然知识和能力的主观评分有显著提高,但两组之间没有统计学上的显著差异。牙科学生的共识是,个性化规划和打印的种植体模型在实践课程中是一种有价值且有效的工具。
