초록
의도적 재식술은 흔히 근관 치료가 실패한 경우 사용되는 치료법이나, 중도의 치주 질환에 이환된 치아에서는 대개 추천되지 않는다. 그러나, 일부 연구들은 의도적 재식술을 이용하여 치주 질환에 이환된 치아를 성공적으로 치료한 것을 보고 한 바가 있다. 본 연구에서는 중도 치주염에 이환된 치아를 의도적 재식술을 이용하여 치료한 증례를 보고하고자 한다. 해당 치아는 근관-치주 복합 병소로 진단 후 근관치료를 선행하였으나 광범위한 골소실을 나타냈으며, 이에 의도적으로 발치 후 치근 표면의 국소 인자를 완전히 제거한 후 재식하였다. 의도적 재식술을 이용하여 본 증례에서 중도 치주염에 이환된 치아를 발치하 지 않고 3년간의 경과 관찰 기간 동안 보존할 수 있었다.
Abstract
Although intentional replantation is frequently used as a treatment modality for endodontic problems, severe periodontal involvement has usually been regarded as a contraindication. However, there are some studies suggesting that intentional replantation could be a successful treatment alternative for periodontally involved teeth. This paper reports the treatment of a tooth with severe periodontal involvement using intentional replantation. The tooth, which had had root canal therapy due to endodontic-periodontal combined lesion but showed extensive bone loss, was gently extracted and replanted after thorough debridement of the root surface. By intentional replantation, a tooth with severe periodontal involvement in this case could be preserved, without extraction, over the course of a 3-year follow-up period.
