Abstract: Intentional replantation has been used as an alternative treatment modality to tooth extraction and prosthetic replacement when conventional endodontic treatment modalities are unfeasible or contraindicated. This case report presents a successful case of intentional replantation for the mandibular first molar with an endodontic mishap. Instrument separated in the apical third of the root canal and extended beyond its mesiobuccal root apex. Intentional replantation served as a means to remove the separated instrument. The PDL cells were kept viable throughout the endodontic treatment using a distinctive technique wherein a pre-operative impression is used for continuous wetting with saline. PRF was shredded and placed in the buccal wall to enhance PDL cell reattachment and prevent ankylosis. The two- year successful follow-up reinforced that intentional replantation can be a viable for removal of separated instruments that lie beyond the root apex. Use of these techniques to keep PDL cells viable and use of PRF can aid in prevention of ankylosis.
