AIM
To identify cephalometric norms for a Jordanian population.
DESIGN
A cross sectional study using a sample selected on the basis of a balanced face and a Class I occlusion.
MATERIALS AND METHODS
65 subjects aged 14-17 years were selected from a larger sample on the basis of Class I incisors, a balanced profile and no previous orthodontic treatment. Lateral skull radiographs were digitised directly to produce values for SNA, SNB, ANB, UI/MX, LI/MN, UI/LI, MMPA and LI/A-Pog.
RESULTS
SNA and SNB were very close to the Eastman Standards. MMPA was significantly lower in Jordanians whilst UI/MX and LI/MN were significantly higher. Lower incisors were 4.6 mm further forward in relation to A-Pog in Jordanians.
目的
确定约旦人群的头影测量标准。
设计
一项横断面研究，样本选取基于面部匀称和I类咬合。
材料与方法
从更大样本中选取65名年龄在14至17岁之间的受试者，入选标准为I类切牙关系、面部轮廓匀称且既往未接受过正畸治疗。将头颅侧位X线片直接数字化，以得出SNA、SNB、ANB、UI/MX、LI/MN、UI/LI、MMPA和LI/A-Pog的值。
结果
SNA和SNB非常接近伊士曼标准。约旦人的MMPA显著更低，而UI/MX和LI/MN显著更高。约旦人的下切牙相对于A-Pog向前4.6毫米。
