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.
咀嚼功能是所有颌骨功能中最重要的功能,通过口腔颌面系统生物力学的协调来维持咀嚼功能是可能的。本研究通过测量牙齿分类咬合力、牙体前牙切面检查咬合情况以及咬肌和颞肌的肌电活动来评价口腔颌面系统的生物力学。测量咀嚼值作为咀嚼功能的检验,调查TMD征象和是否有症状体征作为评估口腔颌骨系统负担的参数,证明咬合接触面积越大,咀嚼功能越强。咀嚼功能也较高,牙齿分类咬合力、正中咬合咬合力或肌肉活动度越高,二者之间的相关性越强。结果表明,由于咬合接触条件和肌肉功能的对称性,咬合力较大,咀嚼功能也较高;在本研究的受试者中,几乎一半的受试者有TMD的体征和症状,但令人欣慰的是,这些受试者的咬合力和咀嚼功能并没有降低。虽然牙体标尺和肌电等是评价口腔颌面系统生物力学的参数,但从本研究的结果无法表明TMD与正常之间的生理范围的数值。然而,人们认为,颌骨功能最重要的咀嚼功能是能够通过分析来评估的。在此基础上提出了改善和维持咀嚼功能的重要建议。
