: To assess the prevalence of posterior crossbite and/or deep bite among patients diagnosed with temporomandibular disorders (TMD) compared to a non-TMD population.: Four hundred ninety-four patients were enrolled: 345 with TMD according to the diagnostic criteria for TMD and 149 without TMD (control group). The chi-square test was used for statistical analysis.: A statistically significant association was found between sleep and awake bruxism and painful TMDs ( < .001 for both), but not with disc displacement. There was no association between posterior crossbite and/or deep bite with either painful TMD or disc displacement.: Within the study limitations, sleep bruxism and awake bruxism may be related to pain in the TMD, and the severity of a deep overbite and presence of a unilateral or bilateral posterior crossbite should not be considered risk factors or as having any effect on the pain associated with TMD and/or disc displacement.
: 评估诊断为颞下颌关节紊乱症（TMD）的患者与非 TMD 人群相比，后牙反合和/或深覆合的患病率。共纳入 494 例患者：345 例根据 TMD 的诊断标准诊断为 TMD，149 例为非 TMD（对照组）。采用卡方检验进行统计学分析。: 结果发现，睡眠和清醒磨牙症与疼痛性 TMD 之间存在统计学显著关联（两者均<.001），但与髁突移位无关。后牙反合和/或深覆合与疼痛性 TMD 或髁突移位之间均无关联。: 在研究的局限性内，睡眠磨牙症和清醒磨牙症可能与 TMD 疼痛有关，深覆合的严重程度以及单侧或双侧后牙反合不应被视为与 TMD 和/或髁突移位相关疼痛的危险因素或有任何影响。
