Intentional Replantation Techniques: A Review
Techniques and armamentarium for intentional replantation have varied throughout the years with no universally accepted clinical treatment guidelines. A wide range of success rates has been reported, and accordingly, this treatment method has often been regarded as a treatment of last resort.

However, recent studies have shown more consistent success rates as high as 88% to 95%. In light of these new studies, intentional replantation may now be considered a more commonly accepted treatment modality. The purpose of this review, published in the Journal of Endodontics was to critically examine reported techniques for intentional replantation.

The selection of intentional replantation as a treatment modality has been controversial. There are many reported indications, yet the procedure has often been considered a last resort option to retain natural teeth. As highlighted, there are several different steps in the procedure, thus the opportunity for many variations of technique and materials.

This may explain the wide range in reported success rates, which are often less favorable than other treatment methods. A recent systematic review found an overall 88% survival rate for intentionally replanted teeth, with more contemporary studies demonstrating success rates as high as 95%. Because of recently reported high survival rates, intentional replantation might now be considered among more commonly accepted treatment options.

It was noted in this same study, however, that only 2 of the articles were published in the past 12 years and also demonstrated differences in clinical technique, thereby limiting the understanding of contemporary intentional replantation practice. Thus, there seems to exist a wide variation in techniques and associated outcomes possibly stemming from the lack of an accepted protocol, as well as a lack of adherence to modern endodontic surgery principles.
