Objectives: To investigate histologically, clinically and radiographically the potentialof Platelet Rich Fibrin (PRF) as a socket graft material to enhance bone regeneration aftertooth extraction and in a trial to minimize alveolar ridge collapse prior to dental implantplacement in the mandible. Patients and Method: Included eight female healthy adultpatients, aged from 19 to 35 years, who were scheduled to undergo extraction of firstmandibular molars before implant placement. Patients were free from any systemicdisease or disorders that could affect the bony healing or affect fibrin clot formation.Atraumatic extraction are performed and the sockets were grafted with PRF & figure 8sutures are done. A re-entry surgery was performed and a core biopsy was taken for eachcase, prior to implant placement. Results: The 8 extraction sockets wounds healeduneventfully & the soft tissue healing proceeded normally as well, with no infection orany adverse reactions. The histological results showed enhanced bone healing within ashort time (4 months of grafting). The statistical results revealed that there wasstatistically significant increase in mean values of bone density postoperatively, fromzero to 4 months observation period. Conclusion: Resorption of the alveolar ridge afterextraction of teeth can be reduced considerably by simultaneous augmentation of thealveolar ridge with platelet rich fibrin.
