摘要

為了要瞭解在台灣中國人的齒顎顏面顱骨形態及探討其在齒科人類學上的特徵，著者等在台灣地區收集12歲男子30名，女子30名及18歲男子36名，女子34名近乎正常咬合者的標準化側方測顱片，針對其顎顏面顱骨形態作分析，經電算機處理及統計分析，求得在台灣中國人的顎顏面顱骨形態的特徵。並從齒科人類學的觀點，與諸學者對日本人，北美白人，中南美印第安人的研究資料作比較，經過分析檢討，得到下列結論：
(1)在台灣中國人，日本人與中南美印第安人間類似點極多，而在較短的顱底部及顏面顱骨形態方面，與北美白人者完全不同。同時在台灣中國人、日本人及中南美印第安人呈現逆時鐘方向成長，而白人則為straight down的成長型式。上下顎骨的A點、B點也較白人者突，上下門牙齒軸也較向唇側傾斜。
(2)在台灣中國人與日本人類似，而與中南美印第安人相異之處為眼窩部平均形態的凹陷度較平坦，不明顯，及擁有較長的顏面高，較平的下顎下緣平面角，較突出的頦部。
(3)在台灣中國人與日本人不同之處在於在台灣中國人上下門牙間角較小，前下顏面高，下顎角、下顎下緣平面角較小。
即在台灣的中國人擁有較寬、較短的臉型，並且以下顎枝呈後移位，下顎角較小呈較直立，前牙較為前凸，為明顯的特徵。

The cephalometric films were collected from 30 boys and 30 girls of 12 years of age, and form 36 males and 34 females of 18 years of age; all of whom were Chinese in Taiwan, all possessed acceptable occlusion to survey the craniofacial morphology and characteristics associated with dental anthropology.
Data were analysed by the computer program at the Department of Orthodontics of Japan Tokyo Medical and Dental University. Data were compard with Japanese, North American Caucasians, Central and South American Indians from papers. It was concluded that:
1) Chinese in Taiwan were similar to Japanese, Central and South American Indians, in That; all possessed a shorter frontal cranial base and depth of face, and were completely different from North American Caucasians. The direction of growth showed counter-clockwise rotation in the four Mongoloid races; however, Caucasians showed straight-down growth. The four Mongoloid races had more frontal position of A,B point and more labial inclination of anterior tooth axis than Caucasians.
2) Chinese in Taiwan were similar to Japanese, but were different from Central and South American Indians, in having a flatter infraorbital outline, longer facial height, flattened mandibular plane angle and a more frontal position of chin.
3) Chinese in Taiwan were characteristically different from Japanese by having a smaller interincisal angle, lower frontal facial height, mandibular angle and mandibular plane angle.
In summary, the results indicated that Chinese in Taiwan are characterized by having a wide but short face pattern, a retroposition of the mandible ramus, a more upright mandible angle and a prominent labial inclination of anterior tooth axis.
