Intentional replantation as the last treatment option for endodontic failure. A narrative review

Abstract

Endodontic failure, characterized by the persistence of a peri-radicular inflammatory lesion in a previously treated tooth, shows a prevalence of 16 to 65% of the world population. There are different treatment options, including non-surgical endodontic retreatment and apical microsurgery. On some occasions, these options are not viable, and intentional replantation appears as an alternative to tooth extraction.

Objective: To analyze clinical aspects, treatment sequence, technical and biological principles, and clinical results of intentional replantation.

Conclusion: In cases of post-treatment endodontic disease, where conventional retreatment is not possible and anatomical limitations exclude the option of apical microsurgery, intentional replantation can be considered as a viable treatment alternative.
