Regenerative Endodontics Treatment on an Autotransplanted Tooth

Dental autotransplantation is a long-standing evidence-based treatment modality to provide a replacement for a tooth within the arch that is unrestorable and deemed for extraction by extracting another clinically healthy tooth from its original location and placing into the extraction socket of the extracted diseased tooth. Autotransplanted teeth have been shown to have a high survival rate and these teeth with the presence of a periodontal ligament in function there can be continued growth of the soft and hard tissue which does not occur with dental implants.

Successful management of teeth with closed apices that have been autotransplantated involves conventional root canal therapy to avoid inflammatory root resorption within two weeks. This case report is of a 18 year old female with a carious upper second premolar and a supernumerary impacted lower premolar. The supernumerary tooth had an apex which had not closed completely and after autotransplantation the tooth splinted for two weeks and subsequently treated with a regenerative endodontic procedure. This was carried out over two visits to initially medicate the tooth and then induce a clot after activating growth factors in the dentin of the canal space. The tooth was sealed with a collagen membrane and a bioceramic restoration to the level of the CEJ. At the follow up, the treatment was deemed successful with a stable autotransplanted tooth in function.
