Poster 167: Tooth Autotransplantation in Combination With Autologous Platelet-Rich Plasma (PRP)

Abstract

Tooth autotransplantation is a promising procedure for recovering the occlusal function of lost teeth, if the periodontal healing is obtained. However, there are a few cases of transplant loss mostly due to the failure of wound healing. Platelet-rich plasma (PRP) is assumed to be effective for promoting wound healing because of some growth factors and the formation of fibrin. Therefore it has been applied to the regeneration of bone and soft tissue in the field of dentistry and plastic surgery. The aim of this study was to assess the efficacy of PRP applied to 5 teeth autotransplantation cases in which wound healing would likely to be unsuccessful since the insufficiency of gingiva and alveolar bone at recipient site; two cases were applied PRP to the socket caused by extirpation of radicular cyst with its tooth because we had planned to transplant tooth to that site in a short period after extirpation, three cases were applied PRP to the socket caused by extraction of donor tooth because donor site was adjacent to recipient site and both gingiva and alveolar bone between the recipient socket and the donor extraction socket were defected.
