A CEPHALOMETRIC STUDY OF KOREAN ADULT WITH NORMAL OCCLUSION BY ARCHIAL ANALYSIS

Accurate evaluation of position, size and morphology of jaws including teeth and alveolar bone is absolutely required to treat dentofacial deformities using combination of surgical-orthodontic technique. Previous analytic methods for orthognathic surgery were mostly forcused on quantative method based on specific cephalometric landmarks. However, considering these could vary in size of facial form for each individual, it is considered better for the facial form of each individual to be evaluated by the ratic between balance and proportional relationship than absolute value. In order to find some acceptably normal positional relationship in the architecture of the head and apply them to diagnosis and treatment in orthognathic surgery, the auther used the lateral cephalometrics of 29 adult men and 25 adult women with normal occlusion. The analysis were based on Archial analysis. The conclusion were as follows; 1) The mean values, standard deviations and standard errors of men and women each were obtained. 2) In the evaluation of the proportion of profile anteroposteriorly, each measured items companing to reference arc were all positioned some posteriorly. 3) In the evaluation of vertical proportions, all anterior and posterior lower faces were longer than the upper faces. 4) The length of mandibular corpus was longer than that of the cranial base. 5) No significant differences were noticed in measured values between men and women.
