영문 초록

The establishment of NORMS on maxillofacial hard and soft tissue structures is very important for patients who need orthodontic and/or orthognathic surgery, because it can contribute to analyse and predict ideal treatment objectives for them. This study was performed to get some useful diagnostic Norms for analysis and prediction of dentofacial deformities of Korean who should be need orthognathic surgery. A gross and direct measuring of anatomic structures on the face of subjects, analysis on the forntal and lateral photometrics (1×1) and analysis on the lateral cephalometrics were done from 119 Korean adults (64 males and 55 females) with normal occlusion and acceptable facial beuty, and compared with each other and Michgan s Norms. The results were obtained as follows: 1. The useful Norms for analysis of orthognathic surgical prediction was made from a gross and direct measurements on the face, photometrics (1×1) and lateral cephalograms. 2. A real distance between medial canthi of the gross meausring and occupying rate of intercanthal width on horizontal plane of frontal photometrics in this study were more higher than those of Michgan s Norm. However, the amount of exposure of the maxillary incisors at rest and interlabial gap were more smaller than those of Michgan s Norm. 3. In Comparison of measurements between lateral photometrics and cephalometrics, vertical ratios on linear measurements were similar, however, three of angular measurements were significantly different and it was higher especially in females. 4. Maxillary skeletal position and degree of inclination of maxillay incisors in this study were similar to Michgan s Norm. However, nasolabial angel was more steeper on both photometrics and cephalograms, and upper lip posture was more anterior than Michigan s Norm. Therefore, I suggest that the steeper tendency of nasolabial angle and anterior positioning of upper lip of Korean were not depended on morphology of the hard tissue but morphological characteristics of the lip itself. 5. Both horizontal position of hard tissue pogonion from NaV-line and soft tissue pogonion from SnV-line were significantly located more posterior than Michgan s Norm, and their position seemed to be located variable from person to person.
