교정적 정출술(Forced orthodontic eruption, FOE)은 각화 치은과 치조골량을 증가시키는 비침습적인 치료 방법이다. 정출력에 의해 치아가 정출되면 치은 섬유와 치주 인대가 신장되고 조골 세포의 유도가 촉진되어 새로운 골형성이 일어나게 된다. 또한 치은 변연이 치관 방향으로 이동되면서 부착 치은의 폭경이 증가된다. 반면, 점막 치은 경계는 일정하게 유지가 된다. 이러한 치료 효과들로 인해 교정적 정출술은 implant site development를 위해 사용될 수 있다. 본 증례 보고에서는 외상으로 인한 치관 파절로 수복이 불가능한 상악 전치부를 교정적 정출술로 연조직 증대를 이룬 후 치조골 이식술(block bone grafting)과 임플란트 식립을 통해 심미적으로 수복한 증례를 통해 교정적 정출술의 효과를 기술하고자 한다.

We evaluated the utility of applying isozyme analysis and two tagging methods, visible implant fluorescent elastomer (VIE) injection and uropod-cutting, to monitor the effects of releasing nursery-reared fleshy prawn (Fenneropenaeus chinensis) into natural habitat in Korea. One hundred thousand farmed prawns (70 mm long) were tagged by clipping off the outer left uropod and injecting them with VIE. This marked seed population was released at Muchangpo, Korea, on 11 and 19 July 2002. Two months later, total catch and catch per unit effort (CPUE) at three locations (Hongwon, Muchangpo, and Anmyundo) were determined. Total catch and CPUE increased nearly 18% over the previous year in Hongwon and Muchangpo. The mixing rate, estimated by uropod regeneration pattern, was 0.33% at Hongwon, 0.53% at Muchangpo, and 0.21% at Anmyundo. The recapture rate was about 3.5%. Isozyme analysis confirmed that the mixing rate was highest at Muchangpo. Moreover, fleshy prawns from Muchangpo were genetically most related to the seed population, indicating that the released prawns had largely remained near the released site. We also confirmed that isozyme genes are valuable as genetic markers for qualitative analyses of a released seed population.
