作者采用X线头影测量一电子计算机系统对100名正常(牙合)广东汉族人的头颅定位正、侧位片进行三维分析。结果表明:颅颌面横向、垂直向的生长发育男性大于女性,而颏部的生长发育女性大于男性;面下部的垂直高度在13岁以后还继续增长;而上颌骨宽度在第一恒磨牙萌出后基本稳定;广东人眼眶的横向距及颅颌面矢状线矩比西安人大,而颅颌面垂直距离及上颌骨宽度、上下牙弓宽度比西安人小。
The authors used an X-cephalometry computer system to perform a three-dimensional analysis of the cranial and lateral radiographs of 100 normal occlusion Han Chinese in Guangdong. The results showed that the growth and development of the cranio-maxillofacial region in the transverse and vertical directions were larger than those in the female and the growth and development of the chin were larger than those in the male. The vertical height of the lower part of the face continued to increase after the age of 13 years. After the basic stability of Cantonese orbital transverse distance and craniomaxillofacial sagittal line than Xi'an, while the vertical distance of craniofacial and maxillary width, upper and lower dental arch width smaller than the Xi'an.
