P latelet-rich fibrin (PRF), developed in France by Choukroun et al (), is a second gen-eration platelet concentrate widely used to accelerate soft and hard. In various bone reconstruction procedures Choukroun’s PRF could provide a possible new bone. Mazor et al., stated that use of PRF as the sole filling. On the other hand, PRF was first used in by Choukroun et al. , specifically in oral and maxillofacial surgery, and is currently considered as a new.

On the other hand, PRF was first used in by Choukroun et al. It includes collection of whole venous blood around 5 ml in each of the two sterile vacutainer tubes 6 ml without anticoagulant and the vacutainer tubes are then placed in a centrifugal machine [ Figure 3 ] at 3, revolutions per minute rpm for 10 min, after which it settles into the following three layers: Following proper protocol and quick handling is the only way to obtain a clinically usable PRF clot charged with serum and platelets.
Additionally, the addition of PRF to the bone graft can lead to a reduction of the volume of bone substitute used and seems to improve revascularization of the graft by supporting angiogenesis [ 37 ]. Abstract The development of bioactive surgical additives to regulate the inflammation and increase the speed of healing process is one of the great challenges in clinical research. Introduction The development of bioactive surgical additives, which are being used to regulate the inflammation and increase the speed of healing process [ 1 ], is one of the great challenges in clinical research.
The aim is to review and discuss the strategies available for use of platelet rich fibrin as healing aid in dentistry. PRF protocol requires only centrifuged blood without any addition of anticoagulant and bovine thrombin [ 1 ]. Platelet-rich fibrin is a Bioscaffold and reservoir of growth factors for tissue regeneration.
Also, PRF may serve as a vehicle in carrying cells involved in tissue regeneration [ 22 ] and seems to have a sustained release of growth factors [ 23 ] in a period between 1 and 4 weeks, stimulating the environment for wound healing in a significant amount of time [ 24 ]. In this sense, platelet rich fibrin PRF appears as a natural and satisfactory alternative with favorable results and low risks.
It was not necessary to expose the PRF membrane layer because in this case it was possible to bind the mucosal margins. In vitro release of growth factors from platelet-rich fibrin PRF: Treatment of a furcation defect with a combination of platelet rich fibrin and bone graft-A case report.
It can hold 12 tubes. It was therefore natural to try to capture the whole amount of monocytes in the PRFto make it more active in stimulating bone grafts, but also to turn to a more rapid transformation of monocytes into macrophages to increase the effect bone stimulation.
This label is given to all practitioners who wish to be updated and to acquire the necessary knowledge to provide high quality education.

It has several advantages and possible indications to be used both in medicine and dentistry. A controlled clinical trial. Inventor of the PRF technique.
PRF membrane has exhibited favorable clinical results in the treatment of periodontal infrabony defects [ 22 ], protecting open wounds from oral environment when the suture cannot bind the mucosal margins [ 13192231 ], and accelerating hard and soft tissue healing [ 193133 ].
This is done fast and each tube is placed into the centrifuge. Simultaneous sinus-lift and implantation using microthreaded implants and leukocyte- and platelet-rich fibrin as sole grafting material: Bone graft, implant and reconstructive surgery.
Simultaneous sinus-lift and implantation using microthreaded implants and leukocyte- and platelet-rich fibrin as sole grafting material: However, using it also presents risk because bovine thrombin, which is used to handle PRP, may generate antibodies to factors V, XI, and thrombin that could cause coagulopathies that may endanger life [ 5 ].
Note the PRF layer over the bone graft.
Recently by showing good promising results with use of the PRF, it has proved to have a good prospect for its use as healing aid in various aspects of the dentistry.

Process for A-PRF – Advanced PRF
Platelet-rich fibrin PRF consists of an autologous leukocyte-platelet-rich fibrin matrix [ 113 ], composed of a tetra molecular structure, with cytokines, platelets, prd, and stem cells within it [ 1119 ], which acts as a biodegradable scaffold [ 20 ] that favors the development of microvascularization and is able to guide epithelial cell migration to its surface [ 1921 ].
