Abstract

This study was designed to investigate dental arch shapes buccally and lingually at Bracket Level of Koreans. This involved studying 63 inviduals (37 males, 26 females) with normal occlusion ranging in age from 17 to 24 years old. The landmarks were digitized and measurements and statistical analysis were performed by NEC 9801 V-M computer. The Results were as Follows: Bicanine width, Bipremolar width and Bimolar width were larger in males than in females. Buccal and lingual arch form and coordination form were obtained by NEC 9801 V-M computer. The parabolic equations which represents buccal and lingual arch form were obtained.

이 연구는 bracket이 붙여지는 위치에서의 이상적인 협측 및 설측 치열궁 형태를 그려내기 위하여 $17\~26$세까지의 정상교합자 63명의 상하악 모헝을 채득하여 계측점과 설정, 통계처리하여 다음과 같은 결과를 얻었다. 치열궁 형태를 나타내는 선계측 항목에서 Bicanine width, Bipremolar width, Bimolar width에서 남자가 여자보다 더 크게 나타났다. NEC 9801 V-M computer를 이용한 graphic 입력을 분석하여 협설측 치열궁 형태를 구하였다. 협측 및 설측 치열궁 형태를 나타내는 포물선식의 상수와 결정계수를 구하였다.
