中文摘要 | 顱底形態與三級異常咬合之間的關係,吾人尚未十分清楚。本研究的目的,在於探討三級異常咬合兒童顱底形態的特徵。比較 100 名三級異常咬合兒童與 100 名正常咬合兒童的側面測顱放射圖形,進行單變項分析與多變項分析的統計檢定,主要結果顯示後顱底呈現最大的差異。結論如下:顱底的長度縮短與角度彎折以及顱底與下顎枝之間的角度減小,導致三級異常咬合以及相關臉形的形成。顱底形態與其他類型異常咬合之間的關係,尚待釐清;值得進一步進行幾何形態學分析的研究,以便更清楚地找出顱底局部變異的位置所在。 |
英文摘要 | The association between cranial-base morphology and Class III malocclusion is not fully understood. The purpose of this study was to investigate the morphologic characteristics of the cranial base in children with Class III malocclusion. Lateral cephalograms from 100 children with Class III malocclusion were compared with those from 100 subjects with normal occlusion. Ten landmarks on the cranial base were identified and digitized. Cephalometric assessment using seven angular and 18 linear measurements was performed by univariate and multivariate analyses. The results revealed that the greatest between-group differences occurred in the posterior cranial-base region. It was concluded that shortening and angular bending of the cranial base, and a diminished angle between the cranial base and mandibular ramus, may lead to Class III malocclusion associated with Class III facial morphology. The association between cranial-base morphology and other types of malocclusion needs clarification. Further study of regional changes in the cranial base, with geometric morphometric analysis, is warranted. |
