Platelet concentrates should be quality-assured of purity and identity prior to clinical use. Unlike for the liquid form of platelet-rich plasma, platelet counts cannot be directly determined in solid fibrin clots and are instead calculated by subtracting the counts in other liquid or semi-clotted fractions from those in whole blood samples. Having long suspected the validity of this method, we...
Different approaches to enhance healing of hard or soft tissues include the use cytokines and growth factors modify cellular behaviour. Numerous are found in autologous blood concentrates - platelet-rich plasma (PRP) fibrin (PRF). Enamel matrix derivative (EMD) may improve tissue via amelogenins. Bilayered collagen (CM) is used for augmentation. The aim present study was assess potential benefi...
Platelets are known primarily for their role in hemostasis, but there is increasing interest in the effect of platelets on wound healing. Platelet isolates such as platelet-rich plasma have been advocated to enhance and accelerate wound healing. This article describes the use of a novel preparation, platelet-rich fibrin matrix (PRFM), for facial plastic surgery applications such as volume augme...
Platelet-Rich Fibrin (PRF) was first described by Choukroun et al., (2001). It has been referred to as a second-generation platelet concentrate, which has been shown to have several advantages over traditionally prepared platelet-rich plasma. PRF has a physiologic architecture that is very favourable to the healing process, obtained due to the slow polymerization process. The development of pla...
objectives : platelet preparations are commonly used to enhance bone and soft tissue regeneration. considering the existing controversies on the efficacy of platelet products for tissue regeneration, more in vitro studies are required. the aim of the present study was to compare the in vitro effects of plasma rich in growth factors (prgf) and platelet-rich fibrin (prf) on proliferation and viab...
A method to produce platelet-rich plasma and platelet concentrate using a double centrifuge technique in combination with the fibrin adhesive Tisseel is described. This technique constitutes the basic mixture for augmenting and improving an inadequate bone site. Also described is a procedure by which autologous bone or bone substitute is added to this mixture to increase the volume of grafting ...
