目的：探讨建立具有高质量牙列的下颌骨三维数字化解剖模型。方法用激光扫描获取1套标准下颌牙列解剖标本的精确三维模型，用CT扫描数据重建下颌骨三维模型，使用基于几何和图像解剖标志的配准变形方法将每颗牙齿模型对齐融合到下颌骨模型，进一步生成牙齿的牙釉质、牙本质、牙周膜。结果成功建立了具有高质量牙列的下颌骨三维数字化解剖模型，每颗牙齿具有牙冠细节和完整的牙根，区分牙釉质、牙本质、牙周膜，可以对任意解剖区域放大和旋转观察，显示解剖标志。结论高质量牙列的下颌骨三维数字化解剖模型具有逼真的三维显象和方便的教学学习功能，可用于口腔、颌面、解剖等多个学科。

Objective To study and establish a high quality digital 3D anatomical modeling of the mandible with full teeth.Methods A set of accurate digital models of standard anatomical specimens of mandibular teeth were obtained by laser scanning, and the 3D mandible model was reconstructed by CT scan data;then, a registration deformation method based on the geometry and image anatomical landmark was employed to do the registration of each tooth to the mandible model, and finally the tooth enamel , dentin, periodontal ligament were generated .Results A high quality digital 3D anatomical modeling of the mandible with full teeth was built , each tooth had detail crown and whole root , the distinction between the enamel , dentin, periodontal ligament , and any anatomical regions can be zoomed and rotately displayed . Conclusion The digital 3D anatomical modeling of the mandible with full teeth has realistic 3D imaging view and convenient teaching-learning function , and has tremendous apllication futures in the stomatology , maxillofacial and other medical departments .
