Abstract

Objective: The purpose of this study was to determine whether an exogenous electric current to the alveolar bone surrounding a tooth being orthodontically treated can enhance tooth movement in human and to verify the effect of electric currents on tooth movement in a clinical aspect. Methods: This study was performed on 7 female orthodontic patients. The electric appliance was set in the maxilla to provide a direct electric current of $20{\mu}A$. The maxillary canine on one side was assigned as the experimental side, and the other as control. The experimental canine was provided with orthodontic force and electric current. The control side was given orthodontic force only. Electrical current was applied to experimental canines for 5 hours a day. The amount of canine movement was measured with an electronic caliper every week. Results: The amount of orthodontic tooth movement in the experimental side during 4 weeks was greater by 30% compared to that of the control side. The amount of increase in tooth movement in the experimental side was statistically significant. The amount of tooth movement in the experimental side during the first two weeks was !Bleater than that in the following two weeks. The amount of weekly tooth movement in the control side was decreased gradually. Conclusions: These results suggested that the exogenous electric current from the miniature electric device might accelerate orthodontic tooth movement by one third and have the potential to reduce orthodontic treatment duration.

교정치료 본질인 치아이동을 보다 효과적으로 하기 위한 기계적 힘외의 다른 자극원으로서 전기적 자극에 대한 효용성이 부각되고 있다. 본 연구는 임상에서 초소형 전기장치에 의한 전기 자극이 교정적 치아이동에 미치는 효과를 실증하기 위해 시행되었다. 교정용 미니 스크류를 식립한 성인 여성 교정 환자 7명의 상악 견치 후방 견인 시 실험측에 150 gm의 기계적 교정력 외에 $20{\mu}A$의 직류 전류를 공급하는 초소형 전기 장치를 고안, 제작, 장착하여 견치의 근원심에 1일 5시간씩 4주간 전류 자극을 흘리고, 대조측에는 기계적 자극만을 가한 후, 매 주간 치아 이동량을 측정하여 치아이동에 있어서 전기자극의 효과를 검증하였다. 실험기간 동안 치아이동률에 있어서 실험군에서 대조군에 비해 1, 2째주에서 33%, 3, 4째주에서 21,4% 증가된 치아이동을 보였다. 실험군의 평균 치아 이동량은 1, 2째주가 3, 4째주에 비하여 컸으며, 그 차이는 각각 47%, 24% 증가된 치아 이동량을 보였다. 실험을 통하여 미세 전류가 적용되어 치아이동을 촉진할 수 있다는 것이 임상적으로 실증되었다. 생물학적으로 최적의 치아이동을 계획하여 치료계획을 단축시킬 수 있는 방법은 기계적 교정력과 전기자극을 동시에 가하는 것이라고 제안한다.
