To evaluate the outcome of Augmented reality technology in the recognizing of oral and maxillofacial anatomy.
This study was conducted on the undergraduate students in Peking University School of Stomatology who were learning oral and maxillofacial anatomy. The image data were selected according to the experiment content, and the important blood vessels and bone tissue structures, such as upper and lower jaws, neck arteries and veins were reconstructed in 3D(3-dimensional) by digital software to generate experiment models, and the reconstructed models were encrypted and stored in the cloud. The QR (quick response) code corresponding to the 3D model was scanned by a networked mobile device to obtain augmented reality images to assist experimenters in teaching and subjects in recognizing. Augmented reality technology was applied in both the theoretical explanation and cadaveric dissection respectively. Subjects' feedback was collected in the form of a post-class questionnaire to evaluate the effectiveness of augmented reality technology-assisted recognizing.
In the study, 83 undergraduate students were included as subjects in this study. Augmented reality technology could be successfully applied in the recognizing of oral and maxillofacial anatomy. All the subjects could scan the QR code through a connected mobile device to get the 3D anatomy model from the cloud, and zoom in/out/rotate the model on the mobile. Augmented reality technology could provide personalized 3D model, based on learners' needs and abilities. The results of likert scale showed that augmented reality technology was highly recognized by the students (9.19 points), and got high scores in terms of forming a three-dimensional sense and stimulating the enthusiasm for learning (9.01 and 8.85 points respectively).
Augmented reality technology can realize the three-dimensional visualization of important structures of oral and maxillofacial anatomy and stimulate students' enthusiasm for learning. Besides, it can assist students in building three-dimensional space imagination of the anatomy of oral and maxillofacial area. The application of augmented reality technology achieves favorable effect in the recognizing of oral and maxillofacial anatomy.
评估增强现实技术在口腔颌面解剖学识别中的效果。
本研究以北京大学口腔医学院正在学习口腔颌面解剖学的本科生为对象。根据实验内容选取图像数据，利用数字软件对上下颌、颈部动静脉等重要血管和骨组织结构进行三维重建，生成实验模型，并将重建后的模型加密存储于云端。通过联网移动设备扫描与三维模型对应的二维码，获取增强现实图像，辅助实验者教学及受试者识别。增强现实技术分别应用于理论讲解和尸体解剖中。以课后问卷的形式收集受试者反馈，评估增强现实技术辅助识别的有效性。
本研究纳入83名本科生作为受试者。增强现实技术能够成功应用于口腔颌面解剖学的识别。所有受试者均可通过连接的移动设备扫描二维码，从云端获取三维解剖模型，并在手机上对模型进行放大/缩小/旋转操作。增强现实技术可根据学习者的需求和能力提供个性化的三维模型。李克特量表结果显示，学生对增强现实技术认可度较高（9.19分），在形成立体感和激发学习积极性方面得分较高（分别为9.01分和8.85分）。
增强现实技术能够实现口腔颌面解剖学重要结构的三维可视化，激发学生的学习积极性。此外，它还能帮助学生构建口腔颌面区域解剖学的三维空间想象力。增强现实技术在口腔颌面解剖学识别中的应用取得了良好效果。
