Abstract
[한글] 저자는 1979년부터 E대 부속국민학교 학생중에서 정상교합과 치열을 가진 7세 아동 66명을 대상으로 상, 하악의 경석고 모형을 채득하여 3년동안 계속적으로 치궁폭경 및 장경을 계측, 분석한 결과 다음과 같은 결론을 얻었다. 1. 상악의 치궁폭경(arch width)은 제이 유구치간 거리 (E-E)를 제외하고는 연령이 증가함에 따라서 남녀 모두 증가하였다. 2. 하악의 치궁폭경 (arch width)은 연령이 증가함에 따라서 남, 녀 모두 현저히 증가하였다. 3. 치궁의 장경(arch length)은 연령이 증가함에 따라서 남, 녀에서 A-C는 현저히 증가하였으나 C-E에서는 거의 변화가 없었다. 4. 상악의 치궁폭경 (arch width)은 7,8세에는 거의 차이가 없었으나 9세에는 남자가 여자보다 컸다. 5. 하악의 치궁폭경 (arch width)은 7세의 E-E부위를 제외하고는 남녀간 차이가 없었다. 6. 상, 하악의 치궁장경 (arch length)은 9세때 하악의 C-E부위를 제외하고는 남, 녀간 차이가 거의 없었다. 7. 상악의 치궁폭경(arch width) 및 장경(arch length)은 하악보다 현저히 컸다. A Longitudinal Study on the Development of Dental Arches in Korean Children Hur Man Wook, D.D.S., M.S.D. Department of Dental Science, Graduate School of Yon Sei University (Directed by Professor Jong rap Lee D,D.S., M.S.D., Ph.D.) The purpose of this longitudinal study was to measure and analyze the width and length changes of dental arches at age 7 to 9.66 children were selected for this study. Stone models obtained from this children were measure and analyze annually. The results were as follows: 1. Widths of upper arch increased with age both in males and females except the region of 2nd deciduous molars. 2. Widths of lower arch increased with age significantly both in males and females. 3. Lengths of dental arches increased with age both in males and females at anterior portion. did not increase at posterior portion. 4. The upper widths of males were wider than those of females at age 9, but no significant difference were present at age 7, 8. 5. The differences of the lower widths between males and females were not present except the region of the 2nd deciduous molars (E-E) at age 7. 6. There were few differences between the lengthes of males and females exceptthe posterior lengthes at age 7. 7. Widths and lengthes of upper arches were difinitely wider and longer than lower arches.
