indications and case series of intentional replantation of teeth

this case series aims to comprehensively introduce intentional replantation with a focus on its indications and case selection in endodontics. in all represented cases, calcium enriched mixture (cem) cement is used for root-end filling. this case series demonstrates twenty cases of ir and extraoral root-end resection and filling with cem cement. all the selected teeth had a failed endodontic treatment and required surgical/nonsurgical endodontic (re)treatment or extraction. subsequent to gentle tooth extraction, an appropriate root-end cavity was prepared and filled with cem cement. then the tooth was replanted; maximun procedure time was 15 min. a total of 18 cases (90%) were successful over a mean follow-up period of 15.5 months. it can be concluded that intentional replantation with careful case selection can have a high success rate over 2 years. intentional replantation may be a suitable treatment option for both trained general practitioners and specialists provided that the extraction is simple and straightforward.
