Abstract：
BACKGROUND: Due to rapid changes in dental practice, digital technologies have become prominent in undergraduate dental education at German universities in recent years. This shift has prompted a re-evaluation of content as well as teaching methods, particularly in courses where students are prepared for patient treatment. Traditional training on standardized models with resin teeth cannot cover the complexity of individual dental arch configuration encountered in patient situations. This study explores the use of 3D printing technology to create individualized models for prosthetic treatment simulations, aiming to evaluate students\' feedback towards their experience with this training setting.
METHODS: First, the study describes the design and fabrication of individualized models with exchangeable teeth based on intraoral scans, mounted on connected plates with distance holders that can be fixed to standard phantom heads. Second, students provided feedback through a questionnaire, assessing various aspects such as the effectiveness of the 3D-printed models compared to traditional frasaco models for preparation exercises.
RESULTS: The results indicated that the design of the realized models was feasible for preparation training (question no. 4: 93% positive rating) and showed positive perceptions of the 3D-printed models, with students finding them effective for preparation exercises and beneficial in bridging the gap between simulation and real patient situations (question no. 6: 69% positive rating).
CONCLUSIONS: The study suggests that 3D printing technology offers a valuable tool in dental education, providing realistic and patient-specific scenarios for students to enhance their skills and readiness for clinical practice. Further improvements in material properties in hand with cost-effective approaches are essential for widespread implementation.

摘要：
背景：由于牙科实践的快速变化，近年来，数字技术在德国大学的本科牙科教育中变得突出。这种转变促使对内容和教学方法进行重新评估，特别是在学生为患者治疗做好准备的课程中。使用树脂牙齿的标准化模型的传统训练无法涵盖患者情况下遇到的单个牙弓配置的复杂性。这项研究探讨了使用3D打印技术来创建用于假肢治疗模拟的个性化模型，旨在评估学生对他们在此培训环境中的体验的反馈。
方法：首先，该研究描述了基于口内扫描的可交换牙齿的个性化模型的设计和制造，安装在连接板的距离持有人，可以固定到标准的幻影头。第二,学生通过问卷提供反馈，评估各个方面，例如3D打印模型与传统frasaco模型相比的有效性，以进行准备练习。
结果：结果表明，实现的模型的设计对于准备训练是可行的（问题号4：93%的积极评价），并显示出对3D打印模型的积极看法，学生发现它们对准备练习有效，并有利于弥合模拟和真实患者情况之间的差距(问题号6：69%的正面评价）。
结论：研究表明，3D打印技术为牙科教育提供了一个有价值的工具，为学生提供现实和患者特定的场景，以提高他们的技能和临床实践的准备。通过具有成本效益的方法进一步改善材料性能对于广泛实施至关重要。
