问题的陈述，需要了解咬合干扰对牙齿、牙周组织，特别是对颌骨功能的影响。本文综述了在动物和人类志愿者牙齿上放置实验性咬合干扰的研究。材料和方法。我们回顾了18项人类研究和10项动物研究的数据。实验咬合干扰分为改变牙尖牙合位置的干扰和仅在Jan侧移时接触的干扰。根据局部牙髓-牙周、颌骨功能或磨牙症效果对这些干预的结果进行分析。实验性最大咬合干扰对患牙的牙周和牙髓组织有有害影响；有时会导致平滑的颌骨功能中断，有时还会导致Jan肌肉疼痛和卡嗒。仅在侧颌运动中接触的实验性咬合干扰很少会对颌骨功能造成损害。此外，没有可靠的证据表明咬合干扰可以引起夜间磨牙症，或阻止它。实验性咬合干扰可导致短暂的局部牙齿疼痛、牙齿松动、姿势肌肉张力水平的轻微变化、咀嚼行程模式，有时还会导致滴答声。由于这些发现存在于相对无症状的患者中，这些数据并不能证明咬合干扰与慢性颌肌疼痛或颞下颌关节功能障碍问题存在因果关系。
Statement of problem, Understanding is needed regarding the effect that occlusal interferences have on the teeth, periodontium, and especially on jaw function.Purpose. This article summarizes research in which experimental occlusal interferences hale been placed on the teeth of animals and human volunteers.Material and Methods. Data from 18 human and 10 animals studies were reviewed. Experimental occlusal interferences were grouped into those that alter intercuspal position and those contacting on lateral jan movement only. The outcome of these interferences were analyzed according to their local pulpal-periodontal, jaw function, or bruxism effects.Results. Experimental occlusal interferences in maximum intercuspation had a deleterious effect on periodontal and pulpal tissues of the affected tooth; sometimes this produces a disruption of smooth jaw function and occasionally jan muscle pain and clicking. Experimental occlusal interferences that contact only in a lateral jaw movement are infrequently harmful to jaw function. Furthermore, no reliable evidence demonstrates that occlusal interferences can cause nocturnal bruxism, or stop it.Conclusion. Transient local tooth pain, loosening of the tooth, a slight change in postural muscle tension levels, chewing stroke patterns, and sometimes a clicking joint can be induced by an experimental occlusal interference. Because such findings are present in relatively asymptomatic patients, these data do not prove that occlusal interferences are causally related to a chronic jaw muscle pain or temporomandibular joint dysfunction problems.
