磨牙症通常被定义为上下牙齿之间的功能异常的紧咬和研磨动作。在这个活动中，可以施加非常强的力，持续时间超过功能性咀嚼的时间。这些生物力学负荷造成许多牙科问题，如牙折，过敏，牙周牵引，颞下颌关节功能障碍。研究磨牙症的研究人员长期以来一直在讨论精神压力和情绪紧张。还表明，攻击性咬与实验动物中应激诱导的脑中去甲肾上腺素周转增加、纹状体DOPAC含量的显著减弱以及胃溃疡形成的预防有关。压力管理的概念基于磨牙症的心理背景和咀嚼肌活动在减轻胃溃疡等压力相关症状方面的益处。咀嚼器官的咬紧和磨牙功能是心理超负荷时期的紧急出口。因此，咀嚼器官的闭合显著有助于个体管理压力的能力。正确牙列期磨牙症可以被认为是所有压力相关疾病的有效系统预防。
Bruxism is generally defined as a parafunctional clenching and grinding action between the upper and lower teeth. During this activity, extremely strong forces can be applied for time periods exceeding those of functional mastication. These biomechanical loads create many dental problems, such as abfractions, hypersensitivity, periodontal distraction, and temporo-mandibular dysfunction. Researchers studying Bruxism have long discussed psychic stress and emotional tension. It has also been indicated that an aggressive biting is associated with a significant attenuation of the stress-induced increase of nor-adrenalin turnover in the brain, of the striatal DOPAC contents and with the prevention of stomach ulcer formation in experimental animals. The concept of stress management based on the psychological background of Bruxism and the benefits attributable to masticatory muscle activity in attenuating stress-related symptoms such as stomach ulcer. The clenching and bruxing function of the masticatory organ is an emergency exit during periods of psychic overloading. Therefore, occlusion of the masticatory organ contributes significantly to an individual's ability to manage stress. Bruxism in proper dentition can be recognized as a valid system prophylaxis for all stress related diseases.
