Abstract

Intentional replantation has been used for alternative treatment for conventional root canal therapy. This case report describes that the intentional replantation with application of extrusive orhodontic force for 6 weeks, on which tooth of previous root canal the-rapy. As preapplicatory orthodontic force, tooth moblity was increased so that extraction of the designated tooth was more easily accomplished and augmented volume of periodontal ligament is expected to acceleated gingival reattachment.
