摘要

Sinus lift surgery is essential after pneumatization caused by loss of posterior teeth. Leukocyte-Platelet-Rich Fibrin (L-PRF) accelerates bone healing by releasing growth factors that promote angiogenesis, cell differentiation, and inflammatory modulation. To evaluate the efficacy of L-PRF in bone healing and repair in sinus lift surgeries, in addition to investigating its role in angiogenesis and inflammatory modulation. The systematic review protocol included definition of the research question, search strategy, inclusion and exclusion criteria, study types, effect measures, screening methods, and data analysis. The search resulted in 860 studies. After removal of duplicates, 704 articles remained, of which 11 met the inclusion criteria. After careful evaluation, 4 studies were considered highly relevant and included in the systematic review. Evidence indicates that the combination of L-PRF with bone grafts, such as DBBM, can accelerate bone formation and allow early implant placement, supported by increased expression of protein markers essential for osteogenesis. The addition of L-PRF to DBBM demonstrated significant benefits in promoting a more favorable bone environment, reducing the time required for osseointegration.
