Orthodontic patients are individuals that grow and develop : therefore selection of the proper time for orthodontic trdatment is considered to be one of the most difficult and yet difficult foctor. Since the development of cephalometric X-ray, amount and pattern of craniofacial growth change with aging could be predicted and became useful in the process of orthodontic treatment. The relationship between the mean values of cephalometric measurements and body helght and weight was studied among the groups(boys and girls) of Koream childern from the ages 0f 3-years to 12-years. 126 boys and 90 girls with no abnormality in growth and development and no history of orthodontic treatment from the ages of 3 years were chosen as subjects: Cephalometric X-ray were takem for 2 years and hard tissue analysis based on Burstone´s COGS, which was divided into measurements of 6 parts (Cranial base, Maxillar and Mandible, Vertical measurements, Horizontal measurements, Basal bone relationchip, Dental measurements.) The relationship between craniofacial growth and body height & weight was studied. The following conclusions were obtained : 1. The maximum growth in the measurements of cranial base, N-Ar(FH) corresponded with the age the maximum increasein body height & weight in both boys and girls. 2. Gonual angle gradually decreased with in both boys and girls. 3. N-ANS(L) showed greater amount of growth than ANS-Me(L), and this had greater influence on facial profile. 4. N-A-Pog° decreased with aging, and mandibular growth exceeded maxillary growth in amount and rate. 5. Length of Y-axis increased, but Y-axis to FH plane remained condtant. This show that mandible grows at a constant angulation to cranial base. 6. As permanert teeth erupt, interincisal angle deceased.
