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.
