Abstract

[한글]

저자는 17세에서 20세 사이에 정상교합을 가진 한국성인 105명과 연세대학교 치과대학 부속병원 교정과에 내원중인 부정교합환자 76명의 두부방사선 계측 사진상에서 "Wits" 수치를 구한후, 서로 비교, 검정하여본 바 다음의 결론을 얻었다.

1. 한국인 성인 남, 여의 "Wits" 정상수치는

남자 : -0.82 mm 여자 : -0.17 mm였다.

2. 정상군의 남, 여 비교에서 "Wits" 정상수치는 유의성이 없었다.

3. ClⅡ. 부정 교합군의 "Wits" 수치의 평균값은 2.68 mm로써, 정상보다 큰(+) 값을 나타내었다.

4. ClⅢ. 부정 교합군의 "Wits" 수치의 평균값은 -8.14 mm로써, 정상보다 작은(-)값을 나타내었다.

Bong Che Cho, D.D.S.

Department of Dental Science, Graduate School, Yonsei University

(Directed by Prof. Young Kyu Ryu, D.D.S., Ph.D.)

The purpose of this study was giving some helpful datas in analysing the degree

of anteroposterior jaw disharmony with the "Wits" appraisal.

The cephalograms of 105 Korean adults with normal occlusion ranging from 17 to 20

years of age and 76 Koreans with various malocclusion ranging from 12 to 24 years

of age were studied and analyzed statistically

The results were as follows :

1. The mean value of "Wits" appraisal in normal occlusion group was -0.82 mm in

males and -0.17 mm in females.

2. There was no significant difference between the males and females in normal

occlusion group.

3. The mean value of "Wits" appraisal in Angle class Ⅱ malocclusion group was

2.67 mm and higher than normal group.

4. The mean value of "Wits" appraisal in Angle class Ⅲ malocclusion group was

-8.11 mm and lower than normal group.
