The aim of the study was to attempt to set average faciometric standards for Egyptians using the Kattan Facio-meter.
Material and Methods
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; p=0.042, Class II divisions 1 and 2 for Orbitale- Labrale superius; p=0.002 and soft tissue ANB; p<0.001. Females showed significantly higher mean value than males for the upper incisor/K plane; p=0.031. Males showed significantly higher mean value for the inter-incisal angle than females; p=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.
Key words:Kattan Facio-meter, Angle Class I, II and III.
