中文摘要 | 顱底形態與二級異常咬合之間的關係,吾人尚未十分清楚。本研究的目的,在於探討二級異常咬合兒童顱底形態的特徵。比較100名二級異常咬合兒童與100名正常咬合兒童的側面測顱放射圖形,賀德林T^2檢定的多變項分析顯現男孩兩者具有統計學上顯著差異性,但女孩則未達顯著水準。結論如下,二級異常咬合兒童的前顱底較長以及顱底角較大。至於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 Ⅱ malocclusion is still not fully understood. The purpose of this study was to investigate the morphological characteristics of the cranial base in children with Class Ⅱ malocclusion. Lateral cephalograms of 100 children with Class Ⅱ malocclusion were compared with their counterparts of 100 subjects with normal occlusion. Ten landmarks on the cranial base were identified and digitized. Cephalometric analysis utilizing 7 angular and 18 linear measurements were undertaken. Multivariate Hotelling's T^2 tests indicated that statistical differences existed between Class Ⅱ groups and normal controls in boys. Nevertheless, there was no significant difference between the two groups in girls. It is concluded that there are longer anterior cranial base and larger cranial base angle in children with Class Ⅱ malocclusion. The association between cranial base morphology and other types of malocclusion needs clarification. Further study with geometric morphometric analysis is warranted. |
