摘　　要：目的研究利用虚拟现实技术,建立三维立体牙颌面影像演示分析系统。方法采用Microsoft Visual C++7.0和OpenGL2.0作为图形开发工具,在个人电脑平台下进行虚拟牙颌面演示分析系统的研制。结果该系统基于个体化牙颌面软硬组织影像学资料所形成的三维立体影像清晰、逼真、立体感强且具有良好的实时交互性,较传统的二维图像或平面三维图像能更清楚、精确地显示和分析牙颌面内外部解剖结构及毗邻关系。结论本系统可提高牙颌面畸形诊断的准确性,具有临床实用价值及推广意义。Objective To study how to use the technology of virtual reality for establishing a demonstration and analysis system of 3D stereoscopic dento-maxillofacial images. Methods The Microsoft Visual C ^＋＋ 7.0 and OpenGL2.0 were used to develop the PC-based virtual dento-maxillofacial demonstration and analysis system. Results The 3D stereoscopic individual dento-maxillofacial images produced by this system were very clear and real. There was a good balance between high-quality rendering and real-time interaction. It can provide a better un- derstanding of dento-maxillofacial anatomic structures and the relationship with the surroundings than 2D image or 3D image on screen. Conclusion The system can increase the accuracy of the diagnosis on dento-maxillofacial deformity.
