项目摘要

The objective of this research were to measure the full range of mandible and solid modeling of the space morphology of movement track traced by each location on the mandible using laser lithography, clarify the characteristics of complex free curved surface displayd by movement space at each location, and to get an insight into the movement of the mandible.It was planned to measure the full movement range of mandibular position at incisal point using the sixdegree-of-freedom jaw movement analyzer, assume the profile morphology of full movement range at arbitrary points on the mandible obtained from the measured mandibular position, complete the solid model that can withstand sufficiently with the analysis on laser lithography and perform the analysis.The targeted model that can withstand sufficiently with the analysis, was then completed. The analysis using solid elucidated the characteristics of the movement space mprphology of each point on the mandible, and the entire movement of t … More he mandible at the incisal point was represented by the solid model. The specifics of the experiment is as follows ;1. Mandibular movement for each type of border movement at incisal point and side-to-side movement for each direction, was measured.2. For the analysis of data, the mandibular position at each border movement at arbitrary points on the mandible and side-to-side movement's mandibular position was compared thus assuming the full movement space morphology for each analyzed points.3. The profile morphology of movement space extraction was made by self designed interpolation algorithm and 3-dimensional CAD software combination using a method that avoids utmost damage with the characteristics of movement space.4. The solid model was then constructed the full movement space morphology at arbitrary points, temporomandibular joint morphology at any mandibular position, and the mandible.The results of this research deepened the understanding on mandibular movements. Especially the qualitative model could relate in establishing further parameter more logically for the diagnosis of mandibular function. Less

本研究的目的是利用激光光刻技术测量下颌骨的全范围，利用激光光刻技术对下颌骨上每个位置所跟踪的运动轨迹的空间形态进行实体建模，阐明每个位置的运动空间所显示的复杂自由曲面的特征，以了解下颌骨的运动情况。计划使用六自由度下颌运动分析仪测量切点位置的下颌全运动范围，假设由测量的下颌位置获得的下颌骨上任意点的全运动范围的轮廓形态，通过对激光光刻的分析，完成了足够承受能力的实体模型，并进行了分析，从而完成了具有足够承受能力的目标模型。利用Solid软件进行分析，阐明了下颌骨各点的运动空间形态特征，以及t…的整个运动过程切口处的下颌骨更多地由实体模型表示。实验的具体内容如下：1.测量每种切点边缘运动类型的下颌运动和每个方向的侧向运动。为了分析数据，比较了下颌骨上任意点的每个边缘运动的下颌位置和侧向运动的下颌位置，从而假设每个分析点的完整的运动空间形态。结合运动空间的特点，采用避免最大破坏的方法，利用自行设计的插补算法和三维CAD软件相结合的方法，对运动空间提取的轮廓形态进行了研究。在此基础上建立了任意点处的完整运动空间形态、任意位置的下颌关节形态以及下颌骨的实体模型，加深了对下颌骨运动的认识。尤其是定性模型可以更合理地为下颌功能的诊断建立进一步的参数。较少
