Abstract:
Intentional replantation (IR) is the intentional extraction of a tooth followed by its replacement back into its socket for the purpose of performing a root-end surgery or other necessary repairs. The procedure may be considered a favorable alternative to conventional microsurgery, especially when surgical access is restricted due to specific anatomical challenges. With advancements in magnification, bioceramics, and instrumentation, IR has become a well-established, scientifically supported treatment modality and is cost-effective when compared to single-implant placement. This article discusses the rationale and indications for IR, describes treatment protocols, and reports on its outcomes.
