The purpose of this study was to investigate the role of malocclusion in temporomandibular disorders (TMD) in an orthodontic patient population prior to treatment. The subjects were 508 Chinese patients (214 males, 294 females), 6 to 56 years of age. The type of malocclusion was diagnosed using dental casts, and TMD signs were recorded by clinical examination. The overall prevalence of TMD signs in the whole group was 26.6%. The frequencies of TMD signs were 44.0% for edge-to-edge bite, 31.2% for posterior crossbite, 27.6% for deep bite, 26.5% for excessive overjet, 26.5% for crowding, 23.7% for anterior crossbite and 23.6% for open bite. Although patients with edge-to-edge bite or posterior crossbite had TMD signs more often than the others in the whole group, the differences did not reach statistical significance. We did not find a significant relationship between morphologic malocclusion and TMD.
本研究的目的是调查错牙合畸形在正畸治疗前患者群体的颞下颌关节紊乱病（TMD）中的作用。研究对象为508名中国患者（男性214名，女性294名），年龄在6至56岁之间。使用石膏模型诊断错牙合畸形类型，并通过临床检查记录TMD体征。整个研究组中TMD体征的总体患病率为26.6%。TMD体征的出现频率在对刃牙合中为44.0%，后牙反合中为31.2%，深覆牙合中为27.6%，深覆盖中为26.5%，牙列拥挤中为26.5%，前牙反合中为23.7%，开合中为23.6%。虽然对刃牙合或后牙反合患者出现TMD体征的频率高于整个研究组中的其他患者，但差异未达到统计学意义。我们未发现形态学错牙合畸形与TMD之间存在显著关联。
