Abstract

Forced orthodontic eruption(FOE) is a non-surgical treatment approach that allows augmenting both soft- and hard-tissue profiles of potential implant sites, by forced orthodontic extrusion of "hopeless" teeth and their periodontal apparatus. By stretching the gingival and periodontal ligament fibers during extrusion, tension is imparted to the entire alveolar socket, stimulating osseous apposition at the alveolar crest. FOE increases the width of the attached gingiva, and the mucogingival junction remains stable when the gingival margin migrates coronally. Based on these effects, FOE of non-restorable teeth prior to implant placement is a viable alternative to conventional surgical augmentative procedures in implant site development. The aim of this case report is to describes coronal soft-tissue augmentation around fractured teeth, which was achieved by FOE before implant placement.

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.
