PURPOSE/OBJECTIVES: Dental students experience difficulties during the transition from preclinical to clinical curriculum. In order to help the students to adapt to the clinical education programme, a simulated practice using patient-based customised models was introduced in this study to prepare for their first clinical practice.
This study included 45 third-year predoctoral students (D3 students) who were about to perform the preparation of a single crown abutment on their first patient. After practicing abutment preparation using simulated models and providing the actual treatment to their own patient, the students were surveyed to investigate their perceptions on the simulated practice using the 3D-printed customised typodont model. The statistical analysis of the quantitative data and the thematic analysis of the qualitative data were conducted.
Regarding this simulation, more than 80% of the students gave positive feedback on their practice of (a) operative positions and postures, (b) finger rest, (c) occlusal reduction, (d) axial reduction and (e) proximal reduction. Student responses on the open-ended questions about how they perceived the usefulness of this simulation were categorised as "First clinical case," "Patient-based model" and "Realistic simulation environment." In addition, a number of improvements of the simulation were also suggested by the students including the typodont and the manikin.
This study gives insights into the significance of simulated practice using patient-based customised typodonts as a transitional education tool and its direction of development in the field of restorative treatments accompanied by irreversible tooth preparations.
目的/目标:牙科学生在从临床前课程过渡到临床课程的过程中会遇到困难。为了帮助学生适应临床教育计划,本研究引入了基于患者的定制模型进行模拟练习,为他们的首次临床实践做准备。
本研究纳入了45名即将对首位患者进行单冠基牙预备的三年级博士前学生(D3学生)。在使用模拟模型练习基牙预备并对自己的患者进行实际治疗后,对学生进行调查,以了解他们对使用3D打印定制牙模型进行模拟练习的看法。对定量数据进行了统计分析,对定性数据进行了主题分析。
关于这种模拟,超过80%的学生对他们在(a)手术体位和姿势、(b)手指支撑、(c)咬合降低、(d)轴向降低和(e)邻面降低方面的练习给出了积极反馈。学生们对关于他们如何看待这种模拟的有用性的开放式问题的回答被归类为“首例临床病例”、“基于患者的模型”和“逼真的模拟环境”。此外,学生们还提出了一些对模拟的改进建议,包括牙模型和人体模型。
本研究深入探讨了使用基于患者的定制牙模型进行模拟练习作为一种过渡性教育工具的重要性及其在伴有不可逆牙齿预备的修复治疗领域的发展方向。
