A LONGITUDINAL ROENTGEN-CEPHALOMETRIC STUDY ON THE CRAN10FACIAL DEPTH AND HEIGHT BY
COBEN'S METHOD

(Directed by Prof. Young Kyu Ryu,D.D.S., Ph.D.)
The morphology and growth changes of the Craniofacial Complex are important in
orthodontics and cephalometrics for analysis and evaluation of facial bone growth
are widely used.The author analyzed the data using lateral cephalomotric
roentgenogram of 75 Korean male and 50 Korean females age of 6 to 10 with normal
occlusion to provide informations-relative rates of facial bone growth of Korean
which is to be contributed in Korean standard.
The results were as follows:
1. Means, standard deviation and coefficient of variation of Korean children werc
obtained.
2. The item which showed significent difference between male and female was
craniofacial height in absolute dimension.
3. No difference of sex was showed in increment f craniofacial height and depth.
4. Among the craniofarial depth increments, the lower facial depth dimension
increased most,midfacial depth dimension increased less, and cranial depth
dimension inceased the least.
5. The horizontal body of mandible showed rapid growing tendency more than did
the ascending ramus.restrictio
