Abstract

INTRODUCTION: Following the immediate implant placement, there is a gap called jumping space which increases the risk of implant failure. OBJECTIVES: The aim of the study was to evaluate the clinical and radiographic efficiency of platelet-rich fibrin membrane (PRF) combined with bone graft surrounding immediate implants in fresh extraction sockets. MATERIALS AND METHODS: A clinical and radiographic study was carried out on ten fresh extraction sockets with age range from 20 to 50 years. Sockets were occupied by immediate endosseous implant and grafted with allogenous bone graft and PRF. After placement all implants were evaluated clinically after 6 months (modified sulcus bleeding index, probing pocket depth and degree of mobility) and radiographically to evaluate marginal bone loss. RESULTS: There was less pain, edema, bleeding and probing depth in the study group than in the control group but the difference among them was not statistically significant (P > 0.05). There was significantly more bone density and less marginal bone loss in the study group than in the control group on the sixth postoperative month (P < 0.05). CONCLUSIONS: It is clear that PRF is biocompatible and can improve both soft tissue healing and bone regeneration after immediate implant placement.
