Study on the Fabrication of High Accuracy Solid Model and its Application using Temporomandibular Joint Data

本研究的目的是从基于实体感觉的高精度实体模型出发，分析人类口腔颌面系统的关节形态与运动的关系。在此基础上，首先开发了一种颞下颌关节数据处理器，然后对关节形态数据和下颌运动数据的测量方法以及光成型矫治器进行了研究，建立了一套能够制作高精度实体模型的加工工艺。此外，对成品模型无法通过图像获得的实体感觉进行了分析。研究结果如下：1.将商用数据设备部件和Intel Pentium 4(3.4 GHz)的4个CPU嵌入无声音箱中，用于制造具有并行运算处理能力的硬件，用于颞颌关节数据处理器。采用LINUX作为软件的操作系统，注重…的自由开发利用图像处理技术和CAD经验，自行设计轮廓提取算法，安排处理环境。2.获取健康受试者的颞颌关节和下颌运动数据。在计算机图形上完成形态数据和运动数据的叠加，并将实体状态的估计结果与实际测量结果进行比较，导致移动过程中各个下颌位置的形态发生变化。3.通过单个实际模型对激光的直径、增量方向和螺距以及增强格子的加工条件进行研究，建立了制作最佳加工状态的技术。4.对于制作的实体模型，完成了任意下颌位置的颞下颌关节形态、重叠的运动范围和颞下颌关节、任意位置的下颌运动和互补的下颌运动形态，并与计算机图形图像进行对比分析。本研究通过建立高精度的下颌关节运动范围实体模型，对理论运动的下颌尖点所经过的轴线的运动范围进行建模，并完成了下颌骨与切点、磨牙、下颌尖点的互补运动模型。较少

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.
