초록

영구치가 선천 결손된 아동에서 유치가 발거되면, 교정적으로 공간을 폐쇄하거나, 성장이 끝나고 임플란트 수복을 시행할 때까지 공간을 유지하게 된다. 그러나 점차 치조골은 위축되고, 향후 보철 수복을 어렵게 하거나 비심미적인 결과를 야기할 수 있으므로, 임상의는 결손 공간과 치조골의 유지 모두 고려해야 한다. 본 증례에는 2개의 하악 전치가 결손된 환아에서 교정용 골성 고정원을 이용한 임시 보철 수복을 시행한 증례이다. 2개의 골성 고정원을 치조정 2 - 3 mm 하방에 수평으로 식립하였으며, 강선이 삽입된 인공치로 고정하였다. 2년의 경과 관찰동안 치은 염증이나 골성 고정원의 탈락은 발생하지 않았다. 또한 방사선 평가에서 인접 치조골의 성장이 저해되지 않았으며, 치조골 폭경 역시 양호하게 유지되었다.

Agenesis of permanent tooth in adolescent patients can be treated either by orthodontic treatment for space closure or by maintaining the space until implant restoration can be carried out in adult. However, gradual atrophy of alveolar bone width makes it difficult to restore the prosthesis in the future or may cause unaesthetic results. Therefore, maintaining of not only the missing space but also the alveolar bone width should be considered. This case is a treatment whereby a temporary replacement of missing 2 mandibular incisors in adolescent patient was carried out using 2 temporary anchorage devices (TADs). Two TADs were placed horizontally 2 - 3 mm below the top of alveolar ridge, and fixed with artificial teeth by stainless steel wires extended. During the 2 year follow-up, neither gingival inflammation nor loss of the TADs have occurred. In the radiographic evaluation, the growth of the adjacent alveolar bone was not inhibited, and the width of the alveolar bone was maintained.
