Fibrina rica em plaquetas associados à substitutos ósseos no tratamento de defeitos periodontais: revisão de literatura

Abstract

In periodontitis, the infectious process causes the destruction of periodontal tissues, as a result of these tissue losses periodontal pockets and defects in bone tissue form. Among the treatments proposed to reduce vertical defects in bone tissue are bone substitutes and such as fibrin-rich platelets (PRF). It is theorized that the union of these regenerative materials would have beneficial effects in the treatment of vertical bone defects and periodontal pocket reduction due to osteoconduction properties of bone substitutes and the release of growth factors released by the PRF. This review aimed to evaluate the use of PRF together with bone substitutes to reduce vertical intraosseous defects in addition to reducing periodontal pockets. For this, a bibliographic search was carried out in the PubMed database with the terms “platelet-rich fibrin”, “Periodontal diseases” and “Intraosseous defects”, filtering the results over a period of 10 years. 10 articles were selected that dealt with the research objective. The results show that both the PRF and the bone substitutes demonstrated a reduction in the bone defect when caused, as well as a reduction in the probing depth and an increase in the clinical attachment level, however superior results are observed with the union of these two that occurred. We thus conclude that the use of PRF together with bone substitutes proves to be more effective in the treatment of intraosseous defects compared to the individual use of materials. However, there is no consensus on some types of bone substitutes.
