虚拟现实技术在口腔诊疗操作培训中的应用

Application of virtual reality technology in oral operation training

虚拟现实(VR)是近年来迅速发展起来的一项高新技术,其操作技能模拟器不但可以模拟实际临床中的常规病例和疑难病例,供学生反复练习其诊疗要领,还可以连续记录操作过程的三维运动和力数据,进行回放观摩和分析,使教学、训练和考核环节变得可量化和标准化,不依赖于特定教师的经验,便于教学和考核;具备沉浸感、想象性和交互性等本质特征。在口腔医学教育领域,VR技术通过建立集成力学和视觉显示的虚拟仿真环境,逼真地再现了口腔医师对真牙操作时的感觉和信息。VR技术在口腔医学各专业领域的操作技能培训中的应用,将改善当下业界仍主要采用体外牙和人工牙来训练口腔医师触觉感知能力及操作技巧的教育环境,有望探索出一条培训口腔医师操作技能的新方法。

Virtual reality（VR） technology has been developing rapidly in recent years. VR has been widely applied in the medical field. A VR dental training system（VRDT） establishes a virtual simulation environment by integrating mechanical and visual display, and reproduces the feeling and information of dental operation on real teeth. The application of VRDT in dental operation training will improve training on the haptic perception and operating skills. VRDT is a highly promising dental educational tool for future applications.
