Fibrina rica em plaquetas e sua utilização na instalação de implantes dentários

Abstract

Platelet Rich Fibrin (PRF) is a second generation platelet concentrate that offers access to growth factors, accelerating the healing of soft and hard tissues and normal pathways for bone regeneration. The objective of this study is to review the literature regarding the benefits and effects of PRF on peri-implant tissue in implant surgery. A search for articles was carried out, in English, using a PubMed database, from 1995 to 2020. Scientific articles included randomized controlled trial, prospective studies, clinical cases and literature reviews. The rehabilitation of a patient after tooth extraction is challenging, because of the bone remodeling process. For successful treatment with a dental implant crown, it is essential that osseointegration occurs, which can be compromised by the absence of adequate bone volume. The literature shows different techniques that try to solve this problem, and PRF is used as one of the possibilities. PRF can improve the preservation of the remaining bone structure after tooth extraction and stimulate bone neoformation in the peri-implant tissue, accelerating the period of osseointegration of the implants; however the benefit in the primary stability of immediate implants subjected to immediate loading is still controversial.
