Abstract:
BACKGROUND:Because the content of oral and maxil ofacial anatomy is various and complex, only the traditional way of multimedia cannot display the anatomical structures from multi-angle and al-round. The development of virtual reality technology in oral and maxil ofacial 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 skul , and establish a multimedia database of oral and maxil ofacial 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 skul were chosen. Each specimen was taken at horizontal and vertical direction by the camera in the center of turntable. Al the images obtained were treated using Photoshop CS5 for dressing and compression. The image data were input into The VR Worx system, fol owed by parameters and hotspots setting and the compression. Final y, 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 skul were constructed with photography and the VR Worx 2.6 software, which could faithful y reproduce the anatomical characteristics of teeth, dentition and skul s, 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 skul . This approach is the entity reconstruction, and the reconstructed model appears clear, vivid, and is easy to be saved and promoted.
