Parafunctional behaviors, especially bruxism, are not uncommon among patient visiting dentists' clinics daily and they constitute a major dental issue for almost all dentists. Many researchers have focused on the definition, pathophysiology, and treatment of these behaviors. These parafunctional behaviors have a considerable negative impact on teeth and dental prothesis. In this review, we focused on the impact of parafunctional behaviors on dental bridges. We summarized the definitions, epidemiology, pathophysiology, and consequences of parafunctional behaviors. In addition, we reviewed previous dental literature studies that demonstrated the effect of bruxism or other parafunctional behaviors on dental bridges and dental prothesis. In conclusion, parafunctional behaviors are common involuntary movements involving the masticatory system. They are more prevalent among children. These behaviors have deleterious effects on dental structures. Causes of parafunctional behaviors include anxiety, depression, smoking, caffeine intake, sleep disorders, or central neurotransmitter dysfunction. Bruxism and other similar masticatory system activity cause dental fracture, loss, and weardown of enamel or teeth. They can also affect different types of dental protheses both fixed and removable types. Parafunctional behaviors shorten the life expectancy of these protheses, and damage residual dentition and denture-bearing tissues.
异常功能行为，尤其是磨牙症，在每天就诊于牙科诊所的患者中并不罕见，并且它们构成了几乎所有牙医面临的一个主要牙科问题。许多研究人员专注于这些行为的定义、病理生理学和治疗。这些异常功能行为对牙齿和牙修复体有相当大的负面影响。在本综述中，我们聚焦于异常功能行为对牙桥的影响。我们总结了异常功能行为的定义、流行病学、病理生理学及后果。此外，我们回顾了以往牙科文献研究，这些研究证明了磨牙症或其他异常功能行为对牙桥和牙修复体的影响。总之，异常功能行为是涉及咀嚼系统的常见非自主运动。它们在儿童中更为普遍。这些行为对牙齿结构有有害影响。异常功能行为的原因包括焦虑、抑郁、吸烟、咖啡因摄入、睡眠障碍或中枢神经递质功能障碍。磨牙症和其他类似的咀嚼系统活动会导致牙齿折断、脱落以及牙釉质或牙齿磨损。它们还会影响不同类型的牙修复体，包括固定和可摘类型。异常功能行为会缩短这些修复体的使用寿命，并损害剩余牙列和义齿承托组织。
