Abstract

Tooth movement facilitated by corticotomy and distraction osteogenesis, new paradigm in orthodontics, was discussed. Intrusive tooth movement of anterior or posterior teeth was thought to be difficult or impossible. In this study, a part of cortical bone, which was a sort of resistance to tooth movement in alveolar bone, was removed. On the other hand, active bone deposition was made possible in the tension side. That was the main concept of tooth movement facilitated by corticotomy and distraction osteogenesis. Teeth moved at such a speedy tate as we could not imagine in conventional tooth movement, which lead to the reduction of total treatment Period. And intrusive movement was Possible without a side effect, lot example, root resorption or the periodontal breakdown. Those were the superior aspects to the conventional orthodontics.

빠르며 정확하고 안전한 치아이동을 목표로 삼고 있는 교정치료에서 새로운 패러다임이라고 여겨지는 피질골 절제술과 견인 골형성술을 응용한 치아이동에 대하여 알아보았다. 일반적인 방법으로는 어렵거나 불가능하다고 여겨지는 치아의 함입 이동을 피질골 절제술과 견인 골형성술을 응용하여 도모하였다. 전치군 및 구치군 각각의 함입 이동 증례를 통해 피질골 절제술과 견인 골형성술의 적용 술식, 견인장치 등을 논하고 그 효과를 파악하였다. 빠른 치아이동과 이에 따른 교정치료 기간의 감소가 가능하고 기존의 교정치료로는 어려웠던 치아이동을 도모할 수 있었으며 무리한 치아이동 시 발생할 수 있는 치근 흡수나 치주조직의 파괴 같은 부작용도 줄일 수 있었다.
