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.
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。
