The aim of the study was to attempt to set average faciometric standards for Egyptians using the Kattan Facio-meter.
The sample consisted of 180 faculty students with age range 17-25 years. It was divided into three groups; Angle Class I, II and III. Class II was further subdivided into divisions 1 and 2. Linear and angular facial measurements in relation to K plane were taken using the Kattan facio-meter. The measurements were correlated to Angle's classification and between genders.
On comparing the different classes, Class II division 1 showed the statistically highest mean value for Orbitale-soft tissue A; =0.042, Class II divisions 1 and 2 for Orbitale- Labrale superius; =0.002 and soft tissue ANB; <0.001. Females showed significantly higher mean value than males for the upper incisor/K plane; =0.031. Males showed significantly higher mean value for the inter-incisal angle than females; =0.001.
Within the limitations of the current study, it was found that both linear and angular soft tissue measurements conformed to the antroposterior skeletal relation of the jaws and that Class II division 1 was due to protruded maxilla. Males had more prominent lips and deeper mentolabial sulcus. Egyptians had less prominent noses than Caucasians. The Kattan Facio-meter was a valuable tool for clinical analysis without the hazards of irradiation. Kattan Facio-meter, Angle Class I, II and III.
本研究的目的是尝试使用卡坦面部测量仪为埃及人设定平均面部测量标准。
样本由180名年龄在17 - 25岁的大学生组成。分为三组：安氏I类、II类和III类。II类又进一步细分为1分类和2分类。使用卡坦面部测量仪进行与K平面相关的线性和角度面部测量。测量结果与安氏分类以及性别进行相关性分析。
比较不同类别时，II类1分类在眶点 - 软组织A方面显示出统计学上最高的平均值；P = 0.042，II类1分类和2分类在眶点 - 上唇突点方面；P = 0.002，在软组织鼻唇角方面；P < 0.001。女性在上切牙与K平面的平均值显著高于男性；P = 0.031。男性的切牙间角平均值显著高于女性；P = 0.001。
在本研究的局限性内，发现线性和角度软组织测量均符合颌骨的前后骨骼关系，II类1分类是由于上颌前突所致。男性嘴唇更突出，颏唇沟更深。埃及人的鼻子不如高加索人突出。卡坦面部测量仪是临床分析的宝贵工具，无辐射危害。卡坦面部测量仪、安氏I类、II类和III类。
