摘要
目的:利用数字人数据集建立人下颌骨的三维数字化可视模型。方法:选择合适的尸体标本,经固定、动脉灌注、包埋、切削、数据采集,获得数字人数据集。取其数据图像中有关下颌骨的二维图像,提取轮廓线,应用Amira软件重建下颌骨。结果:采集到完整精确的下颌骨断面数据,利用软件将数据在三维方向上重建了下颌骨,精确地显示了下颌骨的解剖形态、下颌牙及下颌管的位置与走行。结论:通过数字化虚拟人体数据采集方法获取下颌骨数据集,应用软件重建下颌骨模型,从三维角度观察下颌骨,形态真实,立体感强,为口腔颌面解剖及外科教学、下颌骨疾病的诊断及手术以及下颌牙种植等提供了可视化模型。
PURPOSE： This study is designed to reconstruct 3-D digital visible mandibular model using digital human database. METHODS： An appropriate cadaver was fixed, and fused through arterial infusion, then embedded and sliced. The 2-D imaging data of mandible were obtained from this virtual human, and the virtual mandible was reconstructed using Amira software. RESULTS： Complete and accurate data of the mandible sections were collected, with which the virtual mandible was reconstructed three dimensionally. This virtual mandible displayed accurately the anatomical structure of the actual mandible, including the location and direction of the mandibular teeth and the mandibular canal. CONCLUSION： The 3-D mandible was constructed through the database of the digital human. The visible mandibular model will be an important learning tool in oral and maxillofacial anatomy and surgery, diagnosis and operation of mandibular diseases, and mandibular dental implantation.Supported by Reasearch Fund of Science and Technology Bureau of Shandong Province（Grant No.2003-27）.
