Platelet-rich fibrin application in immediate implant placement

The dental rehabilitation of a patient following single-tooth extraction in the esthetic zone is often clinically challenging. The treatment option for this is implant-supported single crown which has the advantage that adjacent teeth do not have to be prepared, as in a fixed prosthesis. This article presents a case of immediate implant placement in relation to 22 and a guided bone regeneration approach with platelet-rich fibrin (PRF) and bone graft. After immediate implant placement, to compensate for the gap (jumping distance) between the implant surface and bone walls of the socket, we used bone grafts and PRF clot as well as PRF membrane to achieve guided bone regeneration. PRF, which is the second generation platelet concentrate, offers the surgeon an access to growth factors with a simple and available technology. These growth factors, which are autologous, nontoxic, and nonimmunogenic, enhance and accelerate the normal bone regeneration pathways. The case presented showed successful outcome with a 1 year follow-up period.
