项目摘要

In order to-find some useful parameters for functional evaluation of stomatognathic system and to develop a stomatognathic analyzing method, the jaw function of patients with temporomandibular joint (TMJ) dysfunction was compared with that of normal subjects. Moreover, influence of interincisal distance and occlusal contacts of bite plane was examined to make clear the usefulness for treatment of the patients.The results of this study were summarized as follows :1. Simplified gothic arch tracing method is extremely useful for the evaluation of mandibular movement by using such parameters as a magnitude of eccentric movements and a lateral deviation during protrusion in clinical practice.2. When more accurate analysis is necessary, mandibular kinesiograph(MKG), electromyograph (EMG) and occlusal sound are recorded simultaneously in electrically shielded room. These data are carried to a computer system through A/D converter, and analyzed for various parameters.3. Antero-posterior and lateral deviation of mandibular incisal point, the difference between right and left side of muscle activity, and variation of muscle activity duration among tapping strokes, and muscle activity and power spectrum during maximal clenching are the useful parameters for the diagnosis of TMJ dysfunction.4. It is suggested that the bite plane with an interincisal distance of 5mm is most effective in reducing activities of temporal muscles. The behavior of EMG activities was different in between with anterior and posterior occlusal contacts on bite plane. These results suggest the possibility to control EMG activities by applying the bite plane with the proper vertical dimension and occlusal contacts for each patient.

为了找到一些有用的参数，用于对气孔系统的功能评估并开发出气孔分析方法，将颞下颌关节（TMJ）功能障碍患者的下颌功能与正常受试者进行了比较。此外，检查了咬合平面的内部距离和咬合接触的影响，以明确对患者的治疗有用。该研究的结果总结如下：1。简化的哥特式拱形追踪方法对于通过使用此类参数（例如偏心运动的大小）和临床实践中突起期间的横向偏差（2）。当需要进行更准确的分析时，将下颌运动仪（MKG），肌电图（EMG）和咬合声音同时记录在电气屏蔽的房间中。这些数据通过A/D转换器传递到计算机系统，并分析各种参数3。下颌切口点的前后和横向偏差，肌肉活动的右侧和左侧之间的差异以及敲击中的肌肉活动持续时间的变化，最大夹紧过程中的肌肉活性和功率谱是TMJ诊断的有用参数。功能障碍4。建议具有5mm间距离的咬合平面最有效地减少颞肌肉的活性。 EMG活性的行为在咬合平面上与前咬合接触之间有所不同。这些结果表明，通过适当的垂直维度和每个患者的咬合接触的咬合平面来控制EMG活动。
