Temporomandibular joints (TMJ) are one of the most complex joints. Each one is located on one side of the face, and are composed of mandibular fossa, joint tubercle, and condylar process of mandible, separated by an articular disk. To these structures are attached ligaments and muscles, which will provide stability and movement. When TMJs work properly, jaw movements can be performed without pain or discomfort. It is important to mention that the complex formed by both TMJs will confront the maxillary with the mandibular bone and therefore will be related to the occlusion, linking these structures during growth and development.
颞下颌关节(TMJ)是最复杂的关节之一。每个颞下颌关节位于面部一侧,由下颌窝、关节结节和下颌骨髁突组成,中间由一个关节盘隔开。韧带和肌肉附着于这些结构,以提供稳定性和运动功能。当颞下颌关节正常工作时,下颌运动可以无痛或不适地进行。需要指出的是,两个颞下颌关节形成的复合体将使上颌骨与下颌骨相对,因此与咬合有关,在生长发育过程中将这些结构联系起来。
