Temporomandibular dysfunction is a relatively frequent disorder, affecting mainly young women, that remains a poorly recognized entity. Clinical symptoms usually associate pain and cracking of the jaw, frequently accompanied by limitation of opening of the mouth. Occlusal injury is the cause of the dysfunction in every case. Two panoramic radiographs, one in the usual terminal occlusion and the other with the mouth open, provide evidence of the amount of condylar movement and the morphology of the condyles. Active mandibular movements provide muscular re-education. The inhibitors of occlusion (palatine plate to increase incisor elevation or covering plate) have the objective of reducing muscle spasm. Treatment of the cause of the disorder is based on occlusal rehabilitation, surgery of the temporomandibular joint being doomed to failure as it attacks the consequences and not the origin of the occlusal dysfunction.
颞下颌关节紊乱是一种较为常见的疾病，主要影响年轻女性，目前仍是一种认识不足的病症。临床症状通常伴有颌部疼痛和弹响，常伴有张口受限。在每种情况下，咬合损伤都是功能紊乱的原因。两张全景X线片，一张在正常终末咬合时拍摄，另一张在张口时拍摄，可提供髁突运动程度和髁突形态的证据。主动下颌运动可进行肌肉再训练。咬合抑制剂（增加切牙抬高的腭板或覆盖板）旨在减少肌肉痉挛。该疾病病因的治疗基于咬合重建，颞下颌关节手术注定会失败，因为它针对的是咬合功能紊乱的后果而非根源。
