中文摘要 | 本研究目的在探討國內成年人二級第一分類異常咬合之齒列顏面形態的特徵。樣本採用二級第一分類異常咬合與正常咬合成年人各80名的測顱放射線圖。分析方式以單變項分析 (Student's t-test) 及多變項分析 (Hotelling's T^2 test)。另外探討構成二級第一分類異常咬合的因素。綜合本研究結果得知:男性與女性成人二級第一分類異常咬合群齒列顏面形態,除了有大小不同,另外在整體的表現上也有性別的差異,因此就本研究樣本而言,存在兩性二形(dimorphism)的情況。 |
英文摘要 | The aim of this study was to investigate the morphological characteristics of the craniofacial pattern in adults with Class Ⅱ division 1 malocclusion. Lateral cephalograms of 80 adults with Class Ⅱ division1 malocclusion were compared with the data from another 80 adults with normal occlusion. Student's t-test and multivariable analysis (Hotelling's T2 test) was used for statistical analysis. Besides that we also analyzed the combinations of components of Class Ⅱ division 1. The results are as follows: Among the dentofacial characters of Class Ⅱ division 1 in oursamples, there were not only the difference about the size but also the whole appearances between genders. Because of that we defined there was sexual dimorphism in our samples. |
