Use of platelet-enriched fibrin in the protocol for autotransplantation of teeth

Introduction: Autotransplantation (ATT) is defined as the surgical transposition of a tooth from its original place in the alveolar ridge, to a new place in the ridge. The donor tooth can be erupted or impacted, vital or non-vital, with completed or uncompleted root formation. The recipient bed can be a fresh extraction socket, with or without infection, it can have all 4 bony walls, or less than 4, ATT can be finished later (after a couple of weeks following extraction) or in a newly formed socket (prepared bed). Platelet-rich fibrin is defined as an autogenous fibrin clot enriched with platelets and leukocytes, and it can be used as a biomaterial in the form of a plug or pressed membrane. Aim: The study aimed to evaluate the influence of using A-PRF on the soft tissue, bone and root healing and development in autotransplanted teeth in the same patient, via measuring of clinical and radiological parameters. Case report: According to the split mouth design, two procedures were performed on the same patient. In the first case, AT was performed in a classical manner, and in the second case, an A-PRF was included in the surgical protocol. Conclusion: There is a positive tendency for the influence of platelet-rich fibrin on the clinical and radiological parameters of the autotransplanted teeth. Extensive follow-up period and more clinical cases are needed for more specific conclusions about this topic.
