Utilização do PRFL como aditivo na Odontologia

Abstract

The use of PRFL as an additive in dentistry The loss of the teeth promotes a reabsorption of the alveolar bone that often make it harder to the occlusal recovery through the use of implants due to lack of bone support to retain it. Several techniques have been used to recover or even preserve the remaining alveolar bone, such as bone expansion, RTG, autogenous grafts, homologues, heterogens, osteogenic distraction. However, the response to these techniques has not always been adequate in regeneration, often leading to poor morbidity and regeneration. Choukroun et al. (2006), developed the PRF and its use in oral surgery, having several uses in the implantology for bone , greater speed and safety in alveolar reconstructions, maxillary sinus lift, bone tissue augmentation and periodontal surgeries. PRF, being a natural and autogenic bioactive product, presents a simple preparation process in which a portion of centrifuged autogenous venous blood is used, obtaining a fibrin membrane with a high concentration of growth factors and leukocytes that besides stimulating the growth of the Bone and soft tissues. This platelet concentrate further promotes angiogenesis, migration and cell proliferation. For all these benefits, besides being a low-cost procedure, its use in oral surgeries is a viable clinical option.
