This article investigates the influence of occlusion on condylar position as seen on TMJ tomograms in a group of 44 young adults with no histories of orthodontic or occlusal therapy and no objective signs of masticatory dysfunction; the sample was screened from a population of 253 students. Nonconcentric condylar position at ICP was a feature of Class II malocclusion with significantly more anterior positions in Class II, Division 1 than in Class I. Condylar position was unrelated to the amount of sagittal RCP-ICP slide, although most slides were less than 0.5 mm. The frequency of lateral slides was low, but was mildly related to bilaterally asymmetric condylar positions. Position was unrelated to the degree of overbite, which ranged from 0 to 10 mm. Bilateral condylar position asymmetry was not related to the direction of dental midline discrepancy, which ranged from 0 to 2 mm. No open bites or mandibular overjets were seen in this asymptomatic normal sample.
本文调查了44名无正畸或咬合治疗史且无咀嚼功能障碍客观体征的年轻成年人，在颞下颌关节断层扫描图像上所显示的咬合对髁突位置的影响；该样本是从253名学生群体中筛选出来的。正中关系位（ICP）时髁突非同心位置是安氏II类错牙合的一个特征，安氏II类1分类比安氏I类错牙合的髁突位置明显更靠前。髁突位置与矢状面后退接触位（RCP）至正中关系位（ICP）的滑动量无关，尽管大多数滑动小于0.5毫米。侧向滑动的频率较低，但与双侧不对称髁突位置有轻度关联。髁突位置与覆盖范围（从0至10毫米）无关。双侧髁突位置不对称与牙中线差异方向（从0至2毫米）无关。在这个无症状的正常样本中未观察到开牙合或下颌前突。
