阻生牙拔除临床决策分析虚拟仿真教学平台的构建与应用

Development and application of a virtual simulation teaching platform for the clinical decision analysis of impacted tooth extraction

传统阻生牙拔除临床教学中存在学生观察视野狭小,医患沟通培养不足,临床思维培养不足,临床参与度不高等难题亟待解决。本研究以透视颌骨结构、拟定临床策略、沉浸参与临床、涵养医者精神为核心要素,设计“阻生牙拔除临床决策分析虚拟仿真教学平台”,运用虚拟仿真软件创造3D情景虚拟三种不同类型阻生牙临床情境,虚实结合,以临床思维串联阻生牙拔除临床决策分析过程,使学生身临其境地发现、分析和解决阻生牙拔除过程中的医学和人文问题。实验效果问卷调查显示,81.36%(48/59)的学生认为该软件可以提高临床思维能力;76.27%(45/59)的学生认为其有助于掌握阻生牙拔除的基本流程;62.71%(37/59)的学生认为它能提高阻生牙拔除操作技能。因此,该软件通过沉浸式教学体验、构建式教学设计及多维度教学评价,实现了培养学生具备口腔颌面外科临床诊疗思维能力及医生职业素养的目标。

In traditional clinical teaching of impacted tooth extraction,there are problems including limited observation fields for students,insufficient doctor-patient communication training,inadequate clinical thinking development,and low levels of clinical participation.Based on the core elements of visualizing jaw structure with perspective,formulating clinical strategy,immersing in clinical participation,and cultivating the spirit of caregiving,we developed a virtual reality simulation teaching platform for the clinical decision analysis of impacted tooth extraction.The virtual simulation-based platform can create three different impacted tooth scenarios in 3D,which demonstrates the process of clinical decision analysis of impacted tooth extraction through virtuality-reality interaction,allowing students to immerse in the discovery,analysis,and resolution of the medical and humanistic problems in the process of impacted tooth extraction.The questionnaire survey showed that 81.36%(48/59)of the students believed that the software could improve their clinical thinking ability;76.27%(45/59)of the students believed that it could help them master the basic process of impacted tooth extraction;and 62.71%(37/59)of the students believed that it could improve their skills of impacted tooth extraction.By providing immersive learning experience,constructive teaching design,and multi-dimensional teaching evaluation,the software achieved the goals of cultivating students'clinical thinking ability and professional literacy in oral and maxillofacial surgery.
