Temporomandibular disorder (TMD) is a collective term used to identify a group of musculoskeletal conditions of the temporomandibular region. Bruxism is a non-functional activity characterized by repeated tooth clenching or grinding in an unconscious manner. Over the time bruxism may lead to TMD by the uploading it causes. Nasal obstruction is a common complaint that necessitates mouth breathing when severe. The treatment of bruxism is frequently performed by oral appliances, which induce occlusal disengagement and relax jaw musculature and therefore reduce the force on the temporomandibular joint (TMJ). We believe that nasal obstruction may indirectly have a preemptive and therapeutic effect on sleep bruxism related TMD by causing mouth breathing.
颞下颌关节紊乱（TMD）是一个统称，用于识别颞下颌区域的一组肌肉骨骼疾病。磨牙症是一种非功能性活动，表现为无意识地反复咬紧或磨牙。随着时间的推移，磨牙症可能会导致 TMD，因为它会造成牙齿的磨损。鼻塞是一种常见的抱怨，当鼻塞严重时，需要用嘴呼吸。磨牙症的治疗通常通过口腔矫治器来进行，口腔矫治器可以诱导咬合分离，放松颌骨肌肉，从而减少对颞下颌关节（TMJ）的压力。我们认为，鼻塞可能通过引起口呼吸，对与睡眠磨牙症相关的 TMD 产生预防性和治疗性的间接影响。
