Intentional Replantation Techniques: A Critical 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 was to critically examine reported techniques for intentional replantation. A search of the literature on intentional replantation techniques was performed using electronic databases including PubMed, Medline, and Scopus. A total of 3183 articles were generated and screened for relevance based on defined inclusion and exclusion criteria. Subsequently, 27 studies were included for critical review of technique. There has been an evolution in technique for intentional replantation over the decades. Numerous aspects of the procedure exhibit variations, whereas other aspects exhibit considerable consistency. Few studies reported techniques consistent with modern endodontic surgical principles. •More than 3000 articles were evaluated for relevancy to the topic of intentional replantation technique. Twenty-seven articles were critically analyzed for technique, comprising 16 different procedural categories or steps.•Details of reported and advocated techniques in the endodontic literature are demonstrated in both text and table format. In addition, illustrations of various steps in the procedure are provided. Areas of difference and consistency are also highlighted.•Few studies strictly adhered to principles of modern endodontic surgery.
