Abstract
[한글]

Center of resistance는 치아이동 양상을 결정짓는 중요한 요인이다. 저자는 건조두개골에서 상악 견치의 Center of resistance를 찾기 위해 초기 치아 이동과 같은 미세한 움직임의 정확한 정량 분석이 가능한 laser speckle interferometry를 이용하였고 이 결과를 확인하기 위해 laser holographic interferometry를 써서 다음과 같은 결론을 얻었다.

1. degree of rotation의 측정에서는 traction line이 치조골 정상에서 치근단쪽으로 4.4/18.0 level에서 bodily movement를 나타냈고 이 level을 center of resistance라고 할 수 있다.

2. degree of tipping의 측정에서는 center of resistance가 치조골 정상에서 치근단쪽으로 4.6/18.0 level에 위치함을 알 수 있었다.

3. holographic verification에서는 traction level C (3/18)와 D (6/18)사이에서 bodily movement가 일어남을 보여 주었고, 따라서 이 level에 center of resistance가 위치한다고 볼 수 있고 이 결과는 speckle interferometry를 이용한 실험의 결과와 일치하였다.

The center of resistance is a important determining factor of tooth movement pattern.

Laser speckle interferometry, recently developed for noninvasive measurement of small displacements (microns), was used to detect the center of resistance of a maxillary canine which has normal tooth axis and distal curved root in dry human

skull.

Laser holographic interferometry was used to verify the results of laser speckle interferometry.

The following result were obtained;

1. In measurement of the degree of rotation, center of resistance was localized when the traction line passed 4.4/18.0 level from alveola crest to root apex.

2. In measurement of the degree of tipping, center of resistance was localized when the traction line passed 4.6/l8.0 level from alveola crest to root apex.

3. In holographic determination, the center of resistance was observed when the traction line passed between 3mm to 6mm level from alveola crest to root apex, therefore the results using laser speckle interferometry was coincided with holographic results.
