초록

본 연구는 정상 안모이면서 정상교합자인 37명을 대상으로 이마 형태를 분류한 후 분류 기준값을 찾아보았고 이마 분류에 따른 상악 전치의 위치차이를 연구하였다. 또 이마형태에 영향을 주는 인자들과 상악 전치의 위치와의 상관관계를 조사하여 다음과 같은 결과를 얻었다. 1. 이마의 형태는 angular, round, straight, concave 형태로 구분 가능하다. 2. 이마의 형태를 분류할 수 있는 특정 기준 값은 존재하지 않았지만 S value와 이마길이(Tri-Gla)를 이용하여 이마형태의 분류 가능성이 존재하였다. 3. 이마의 형태에 따른 상악 전치의 위치는 차이는 존재하지 않았다. 4. 이마 기울기와 Andrews 분석값은 유의한 음의 상관관계를 갖는다. 즉 이마 기울기가 커질수록 상악 전치는 후방 위치하게 되며 다음과 같은 공식 Andrew analysis = -0.39*Forehead inclination으로 표현할 수 있다.

In this study, 37 subjects with normal facial shape and normal occlusion are classified and reference value for such classification was investigated. Difference in position of maxillary incisor was studied according to the cl assification. Moreover, by investigating correlation between factors affecting forehead morphology and positio n of maxillary incisor, following results have been obtained. 1. Morphology of forehead can be classified as angular type, round type, straight type, and concave type. 2. There were no specific reference value for evaluation of forehead morphology but possibilities of evaluating forehead morphology using S value and forehead length (Tri-Gla) still remain. 3. There were no correlation between forehead morphology and position of maxillary incisor. 4. Forehead inclination and Andrew analysis show statistically significant negative correlation. That is, as forehead inclination increases, maxillary incisor is positioned posteriorly and this relationship can be shown as following equation, Andrew analysis = -0.39*Forehead inclination.
