Abstract

Autotransplantation of third molars with completely formed roots is known to be effective and provide a high long-term success rate. However, in case of severe mobility or unexpectedly extraction is observed during the monitoring period after surgery, it is generally considered as a failure. This case report describes successful replantation of autotransplanted mature third molar into surgically created molar socket. 1 year follow up of transplanted tooth showed clinically normal periodontal pocket depth and tooth mobility. Root resorption or bone loss were not observed. Provided that there is no apparent sign of inflammation, re-insertion into socket is a viable alternative to immediate determination of extraction.

성숙된 치근을 갖는 제3대구치를 이용한 자가치아이식술은 효과적이며, 장기간 높은 성공률 보여주는 것으로 알려져 있다. 자가이식술 이후 생착 여부에 대해 경과 관찰하는 기간동안 치아가 심한 동요도를 보이는 경우, 이를 실패로 간주하고 발치를 하는 것이 일반적이다. 하지만, 이번 증례에서는, 자가치아 이식술 후 치아가 고정이 되지 않아, 구강 외로 탈락되었으나, 시기 적절히 재식을 시도하여 다시 생착을 획득하였고, 1년 이후까지도 성공적인 임상 결과를 보였다. 재식하였지만, 치근 흡수나 골소실도 보이지 않았다. 자가치아이식 후 교합적 문제로 고정을 보이지 않으나, 염증소견이 없는 치아라면 치조와에 재식하는 것이 발치에 앞선 대안이 될 수 있다.
