下颌开闭口运动的三维数字化虚拟还原
Three-dimensional digital reduction of jaw opening and closing movement
目的 利用Motion capture运动捕捉及分析系统，获得下颌开闭口运动的6个自由度，结合上下颌骨三维数字化模型，实现下颌运动轨迹还原，为下颌运动虚拟仿真奠定了基础。 方法 1例咬合关系正常的健康成年男性，Motion capture运动捕捉及分析系统采集开闭口运动过程，获得下颌运动的6个自由度。CT图像重建上下颌骨独立的三维数字模型，在Autodesk 3dsmax 8.0中实现下颌开闭口运动还原。 结果 在Autodesk 3dsmax 8.0中，还原了下颌开闭口运动，清楚显示上下颌骨的位置变化关系，上下颌牙列在开闭口运动中的变化，颞下颌关节结构对应变化关系。 结论 Motion capture运动捕捉及分析系统采集6个自由度结合CT重建的上下颌骨三维数字化模型准确还原了下颌开闭口运动，量化可视化了下颌运动过程。
Objective To explore a three dimensional digital displayed method of mandibular movement, and provide a basis for the virtual reality of mandibular motion. Methods 1 case of male adult, with the integrated dentition, and no temporomandi-bular joint disorders was used in this study. The independent three-dimensional digital jaw model was reconstructed with CT image in Mimics11.0. The three-dimensional digital reduction of jaw opening and closing movement with six degrees of freedom was set up in Autodesk 3dsmax 8.0. Results Through the three-dimensional digital jaw opening and closing movement, the location between the upper and lower jaw, dentition, occlusion and the structures of the temporomandibular joint could be demonstrated clearly. Conclusions Adopting autodesk 3dsmax 8.0, virtual reality of jaw movement with six degree-of-freedom and 3D digital jaw models can be built, which is feasible to quantify and visualize the course of the mandibular movement.
