摘要：

背景：由于口腔颌面解剖的内容繁多，结构层次复杂，仅靠传统的多媒体方式很难将复杂的解剖层次多角度、全方位的展现出来。虚拟现实技术在口腔颌面解剖三维重建方面的研究发展迅速，引起众多学者的关注，成为了研究的热点。
目的：构建实体离体牙、牙列及颅骨的三维数字化可视模型，建立口腔颌面解剖数字资源库，使其信息化、网络化，为口腔医学的基础和临床教育教学提供新方法。
方法：选择一批冠根完好的离体牙及颅骨模型。利用数码相机，分别在水平、垂直方向的不同角度对每一个模型拍照。将拍摄好的图片导入Photoshop CS5，进行图片修整压缩。将获取的图片导入The VR Worx系统，设置各种参数、热区，压缩，最后将制作完成的牙体三维数字化可视模型的QuickTime VR对象影视输出至磁盘上。
结果与结论：通过数码相机结合The VR Worx 2.6软件进行三维重建，可以建立实体的牙体、牙列及颅骨的三维数字化可视模型。此模型可以在一定角度旋转、观察、缩放，同时可以对特殊的解剖部位进行标记设置热区。因此，利用数码相机结合The VR Worx 软件为平台，开发实体标本的三维数字模型是可行的。这种制作方法是实体的重建，制作出的模型可以清晰展示标本的解剖结构，形象生动，并且易于保存推广。

Abstract:

BACKGROUND: Because the content of oral and maxillofacial anatomy is various and complex, only the traditional way of multimedia cannot display the anatomical structures from multi-angle and all-round. The development of virtual reality technology in oral and maxillofacial anatomy of three-dimensional reconstruction research is rapid, causes the attention of many scholars, and has become a hot spot.
OBJECTIVE: To develop a three-dimensional digital model of tooth, dentition and skull, and establish a multimedia database of oral and maxillofacial anatomy to facilitate network sharing and information dissemination so as to provide new method for teaching of basic and clinical oral medicine.
METHODS: Extracted teeth with intact crown and root, dentition and skull were chosen. Each specimen was taken at horizontal and vertical direction by the camera in the center of turntable. All the images obtained were treated using Photoshop CS5 for dressing and compression. The image data were input into The VR Worx system, followed by parameters and hotspots setting and the compression. Finally, the three-dimensional digital models were reconstructed and output with QuickTime VR format into disk. 
RESULTS AND CONCLUSION: Three-dimensional digital models of tooth and skull were constructed with photography and the VR Worx 2.6 software, which could faithfully reproduce the anatomical characteristics of teeth, dentition and skulls, and facilitate researchers to rotate and scale for observation. Also, it was easy for hotspot-marking. On the platform of digital photography and The VR Worx software, it is feasible to establish the three-dimensional digital model of tooth and skull. This approach is the entity reconstruction, and the reconstructed model appears clear, vivid, and is easy to be saved and promoted.
