The role of fibrin rich in platelets and leukocytes in the bone healing of calvary defects: study in rabbits

Introduction: L-PRF is a concentrate of platelets and leukocytes in a fibrin network, obtained by autologous centrifugation collected at the time of surgery. It is part of the second generation of platelet concentrates, being low cost, easy to prepare, simple to obtain and has the ability to accelerate the healing of soft and hard tissues. Objective: To review bone repair of non-critical calvarial defects using L-PRF alone and in association with particulated autogenous bone. Method: Integrative review of literature taken from the SciELO, Pubmed and Scopus platforms in English and Portuguese using the following descriptors: “L-PRF, bone healing, calvarial defects, rabbit” in AND or OR by the title or summary. After selection, only articles considered relevant were read in full. Results: 39 articles were included. Conclusion: L-PRF alone had a positive effect on bone formation over the weeks.
