Mandibular function, headaches, and symptoms and signs of temporomandibular disorders (TMD) were studied in one group of girls with a well-defined normal occlusion (n = 60) and another group with class II malocclusion (n = 123). Frequent headaches and temporomandibular joint clicking, muscle tenderness to palpation, pain on mandibular movement, awareness of tooth clenching, and grinding were commoner in the class II malocclusion group. Awareness of tooth clenching had the largest influence on the odds for symptoms and signs of temporomandibular disorders (TMD) in a logistic regression analysis. Occlusal variables that increased the odds for symptoms and signs of TMD were large overjet, frontal open bite, few occlusal contacts, lateral sliding retruded-intercuspal contact position, crowding, and non-working side interferences. We concluded that normal occlusions have lower odds for symptoms and signs of TMD, whereas some occlusal characteristics, more frequently found in the class II malocclusion group, increased the odds for symptoms and signs of TMD.
对一组具有明确正常咬合的女孩（n = 60）和另一组安氏II类错牙合畸形的女孩（n = 123）的下颌功能、头痛以及颞下颌关节紊乱病（TMD）的症状和体征进行了研究。在安氏II类错牙合畸形组中，频繁头痛、颞下颌关节弹响、触诊时肌肉压痛、下颌运动时疼痛、咬牙和磨牙的意识更为常见。在逻辑回归分析中，咬牙意识对颞下颌关节紊乱病（TMD）症状和体征的几率影响最大。增加TMD症状和体征几率的咬合变量包括深覆盖、前牙开牙合、咬合接触少、侧方滑动后退-牙尖交错接触位、牙列拥挤和非工作侧干扰。我们得出结论，正常咬合出现TMD症状和体征的几率较低，而在安氏II类错牙合畸形组中更常见的一些咬合特征会增加TMD症状和体征的几率。
