Abstract

著者는 서울市에 居住하는 3∼5歲의 小兒 266名을 對象으로 乳齒列의 咬合樣相을 觀察한
바 다음과 같은 結論을 얻었다.
1) Sagittal canine relationship에 있어서 Class 1 pattern이 63.9%(170名, Class 2 pattern
이 2.3%(6名), Class 3 pattern이 21%(56名)이었고 12.8%(34名)가 左右側이 다르게 나타났
다.
2) Sagittal molar relationship에 있어서 Class 1 pattern이 44.3%(118名), Class 2 pattern
이 6.1%(16名), Class 3 pattern이 32.3%(86名)이었고 17.3%(46名)에서 左右側이 다르게 나
타났다.
3) Overjet는 2mm以內가 87.8%(234名)였고 Overbite는 3mm以內가 83.2%(218名)였다.
4) Crossbite는 5.3%(14名), Scissors-bite는 4.6%(12名)였다.
5) Midline deviation은 21.8%(58名)였다.
6) Primate space는 Interdental space의 好發部位와 一致하였다.

The author studied occlusion in the primary dentition of 3∼5 year old children and the
materials for the prevent study comprised plaster model of 266 children in Seoul.
The results were as followings;
1) In sagittal canine relationship, 63.9% (170 children) showed crass 1 pattern, 2.35(6
children) showed class 2 pattern, 21%(56 children) showed class 3 pattern and 12.8%(34
children) showed a different canine relationship in each side.
2) In sagittal molar relationship, 44.3% (118 children) showed class 1 pattern, 6.1%(16
children) showed class 2 pattern, 32.3%(86 children) showed class 3 pattern and 17.3%
(46 children) showed a different molar relationship in each side.
3) In overjet, 87.8% (234 children) showed under 2mm.
4) 5.3%(14 children) showed crossbite and 4.6% (12 children) showed scissors-bite.
5) 21.8%(58 children) showed midline deviation.
6) Primate space was coincided with more common position of interdental space.
