The single most common contributing factor in the onset of TMJ disorders is cranio cervical trauma. This is strongly supported by the referred literature and a wide range of clinical experience. Trauma is also one of the most frequently overlooked factors when developing an occlusion related treatment plan. Failure to take into account a previous injury that has caused permanent damage to the TMJs could prove to be very embarrassing. If the symptoms are in remission at the initiation of occlusal therapy, a tense situation can arise if an old injury becomes acute during treatment and the patient mistakenly assumes that the occlusal therapy was the proximate cause of the flare up in symptoms. Pretreatment screening for TMJ injuries is extremely important and can have substantial impact on the final therapeutic course.
颞下颌关节紊乱症发病的最常见单一因素是颅颈创伤。这一点得到了参考文献和广泛临床经验的有力支持。在制定与咬合相关的治疗方案时，创伤也是最常被忽视的因素之一。未能考虑到先前已对颞下颌关节造成永久性损伤的创伤，可能会变得非常尴尬。如果在咬合治疗开始时症状处于缓解期，而旧伤在治疗期间转为急性，且患者错误地认为咬合治疗是症状突然加重的直接原因，就可能会出现紧张局面。治疗前对颞下颌关节损伤进行筛查极为重要，且会对最终的治疗过程产生重大影响。
