摘要
目的 进行基于CT断层影像的下颌骨及下牙列三维几何学仿真。方法 结合牙CT技术 ,采用交互式人机对话提取CT断层影像二维轮廓数据 ,应用美国PTC公司微机版Pro/Engineer和英国DELCAM公司POWERSHAPE等应用软件建立下颌骨及下牙列三维线框模型和实体模型。结果 得到了具有真实感的下颌骨及下牙列的三维实体模型 ,该模型能够进行三维显示 ,模型可编辑性强。结论 几何学仿真模型为快速原型和下颌骨及下牙列的力学仿真模型等进一步应用和研究打下了基础。本文采用的几何学仿真方法切实可行 ,在口腔颌面外科、骨科等领域有良好的应用前景。
Objective A 3D geometric simulation of mandible with dental arch from CT has been obtained in this study. Methods This process uses automatic system assisted with interactive action to get 2D contour data from CT images, then 3D wireframe model and solid model were obtained by using CAD/CAM software Pro E(USA) and DELCAM(UK).Results 3D solid model of mandible with dental arch were presented which can be fully edited. Conclusions This model can be applied to further educational and clinical researches such as RP , biomechanics simulation in prosthetic dentistry. The processes of simulation has wide applications in clinical practice of dentistry and dental education. [
