项目摘要

The chewing function is the most important function in all jaw functions, and it is possible to be maintained by harmony of stomatognathic system biomechanics.In this study, the data by measurement of tooth classification biting force, examination of the occlusal condition by dental prescale and the electromyographic activties of masseter and temporal muscles was recorded for the student of this faculty of dentistry as an evaluation of the stomatognathic system biomechanics. The chewing value was measured as an inspection of the chewing function, and sign of the TMD and existence of the experience of the symptom by the inquiry were investigated as the parameter which estimated the superfluous burden to the stomatognathic system.It was proven that the chewing function was higher, as the occlusion contact area is bigger. The chewing function was also higher, as the tooth classification biting force, biting force in centric occlusion or muscular activity are higher, the correlation is comparatively stronger between each other. It was shown that the biting force was bigge and the chewing function is also higher, as the occlusal contact condition and muscle function are more symmetrical.In the examinee of this study, almost half of the subjecs have the experience in sign and symptom of the TMD.But it was happy that biting force and chewing function did not lower in these subjecs.Though the dental prescale and electromyograms, etc.were the porameters which evaluated the stomatognathic system biomechanics, it was impossible to indicate numerical value for physiological range between TMD and nomal from the result of this study. However, it is considered that the most important chewing function of the jaw function was able to be evaluated analytically. Then the important sugestion for improving and maintaining the chewing function was given by this study.
咀嚼功能是颌部所有功能中最重要的功能,咀嚼功能的维持离不开口颌系统生物力学的协调。在本研究中,通过测量牙齿分类、咬合力、牙齿预分片检查咬合状况以及咬肌和颞肌肌电图活动,为该牙科学院的学生记录了数据,作为对口颌系统生物力学的评估。测量咀嚼值作为咀嚼功能的检验,并通过询问来研究TMD的标志和症状体验的存在性,作为估计口颌系统多余负担的参数。结果表明,咬合接触面积越大,咀嚼功能越强。咀嚼功能也较高,由于牙齿分类咬合力、中心咬合咬合力或肌肉活动咬合力较高,两者之间的相关性相对较强。结果表明,由于咬合接触条件和肌肉功能更为对称,咬合力较大,咀嚼功能也较高。在本研究的被试中,几乎有一半的被试有过TMD的症状和体征。但令人高兴的是,这些受试者的咬合力和咀嚼功能并没有降低。虽然牙前刻度和肌电图等是评价口腔系统生物力学的参数,但本研究结果无法给出TMD与正常生理范围的数值。然而,人们认为颌骨功能中最重要的咀嚼功能是可以用解析法来评估的。本研究对改善和维持咀嚼功能提出了重要建议。
