项目摘要

The aim of this research is to analyze the relationship between morphology of temporomandibular joint and movement for human stomatognathic system from high accuracy fabricated solid model based on substantial sense.Based on the research protocol, first a temporomandibular joint data processor was developed and then the temporomandibular joint morphology data and measurement methods of mandibular movement data and light molding appliance, a processing technology could be established allowing the fabrication of high accuracy solid model. Further, an analysis was conducted regarding substantial sense on finished model, unable to obtain through image. The results are as follows :1.Commercially available data appliance parts and 4 CPUs from Intel Pentium 4 (3.4 GHz) embedded into a silent sound housing for fabrication of a hardware capable of parallel operation processing were applied for temporomandibular joint data processor. Linux adopted as software's OS focusing the freedom of develop … More ment and the processing environment arranged by self-designed profile extracting algorithm utilizing the image processing technology and CAD experiences.2.Data measurement for temporomandibular joint and mandibular movement was obtained from healthy subjects. The superimposition of morphology data and movement data was completed on the computer graphics, and the results of estimated solid condition compared with those of obtained by actual measurement, resulting in change of morphology for each mandibular position during movement.3.The high accuracy solid model was investigated by individual actual model for laser beam's diameter, incremental direction and pitch and processing condition of reinforced lattice, establishing a technology to fabricate the best processing status.4.For fabricated solid model, morphology of temporomandibular joint in arbitrary mandibular position, superimposed movement range and temporomandibular joint, mandibular movement in arbitrary position and complementary mandibular movement morphology were completed, and analyzed by comparing those images obtained via computer graphics.This research elucidated the temporomandibular joint movement with the fabrication of high accuracy solid model for movement range to the axis where theoretical movement condylar point passes through and completion of model for complementary mandibular movement to incisal point, molars and condylar point.

本研究的目的是从基于实体感的高精度实体模型出发，分析颞下颌关节形态与人体口颌系统运动的关系，在此基础上，首先开发了颞下颌关节数据处理器，然后研究了颞下颌关节形态数据、下颌运动数据测量方法和光塑矫治器，可以建立允许制造高精度实体模型的处理技术。此外，对无法通过图像获得的成品模型进行了实质性意义分析。结果如下：1.颞下颌关节数据处理器采用市售的数据家电部件和4个Intel Pentium 4（3.4GHz）CPU，嵌入静音外壳中，构成具有并行运算处理能力的硬件。采用Linux作为软件操作系统，注重开发的自由度 ...更多信息利用图像处理技术和CAD经验，自行设计了轮廓提取算法，并布置了处理环境。2.对健康受试者的颞下颌关节和下颌运动进行了测量。在计算机图形学上完成形态数据与运动数据的叠加，并将实体状态估计结果与实际测量结果进行比较，得出运动过程中下颌骨各位置的形态变化。3.通过对激光束直径、增量方向、间距以及加强网格加工条件的个体化实际模型，研究高精度实体模型。4.对所制作的实体模型，完成了下颌任意位置的颞下颌关节形态、运动范围与颞下颌关节的叠加形态、下颌任意位置的运动形态以及下颌运动的互补形态，本研究通过计算机图形学的方法对颞下颌关节的运动进行了分析，建立了理论运动髁突点经过轴线的运动范围的精确实体模型，完成了下颌骨与切点、磨牙和髁突点的互补运动模型。少
