Abstract：
OBJECTIVE: To evaluate the outcome of Augmented reality technology in the recognizing of oral and maxillofacial anatomy.
METHODS: 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.
RESULTS: 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).
CONCLUSIONS: 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.

摘要：
目的：评价增强现实技术在口腔颌面部解剖识别中的应用效果。
方法：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研究对象。根据实验内容选择图像数据,以及重要的血管和骨组织结构，例如上颚和下颚，通过数字软件以3D（3维）重建颈部动脉和静脉以生成实验模型，重建的模型被加密并存储在云中。通过联网的移动设备扫描与3D模型相对应的QR（快速响应）代码，以获得增强现实图像，以帮助实验者进行教学和受试者进行识别。增强现实技术分别应用于理论解释和尸体解剖。以课后问卷的形式收集受试者的反馈，以评估增强现实技术辅助识别的有效性。
结果：在研究中，83名本科生被纳入本研究。增强现实技术可以成功地应用于口腔颌面部解剖结构的识别。所有受试者都可以通过连接的移动设备扫描QR码，从云端获取3D解剖模型，和放大/缩小/旋转移动模型。增强现实技术可以提供个性化的3D模型，基于学习者的需求和能力。likert量表结果显示,增强现实技术得到了学生的高度认可(9.19分),在形成立体感和激发学习热情方面获得了高分（分别为9.01和8.85分）。
结论：增强现实技术可以实现口腔颌面解剖重要结构的三维可视化，激发学生的学习热情。此外,它可以帮助学生构建口腔颌面部解剖的三维空间想象。增强现实技术在口腔颌面部解剖识别中的应用取得了良好的效果。
