PRF (Platelet Rich Fibrin)

 What is PRF?

 Platelet-Rich Fibrin (PRF) is a groundbreaking new technique in regenerative medicine that many patients are benefiting from.  PRF is a meshwork of cytokines, growth factors, and cells that are harvested from a small amount of the patient’s own blood. This blood is spun at a specific rate and time to form a fibrin clot full of regenerative potential.

  

 What is PRF used for?

 PRF has many applications including the following:

 Preventio of dry socket after tooth removal – PRF placed into an extraction site

  • Regeneration of bone after tooth removal – PRF placed into an extraction site
  • Soft tissue grafting – PRF placed over area of soft tissue deficiency to assist in soft tissue healing
  • Regeneration of bone after removal of cysts and other maxillofacial pathology – PRF placed into bony defect
  • Closure of oroantral communication/fistula – PRF placed over defect
  • Sinus lifts – PRF placed over lifted sinus membrane to assist in bony fill and maintenance of sinus health
  • Cosmetics/Skincare – Injectable PRF used for hair and skin rejuvenation and treatment of deep scarring and skin hyperpigmentation

Why use PRF?

 Surgeons and patients alike are benefiting from the use of PRF in surgical applications. From increasing post-operative comfort to assisting in regeneration of natural tissues PRF offers vast advantages

  • Significant decrease in patient discomfort. The use of PRF has been shown to reduce the risk of complications and restrictions a patient may experience. The result is a notable decrease in patient discomfort, post-surgical pain, and post-op bleeding.
  • It’s 100% natural and safe and easy to produce. PRF is derived from a patient’s own blood and processed and optimized for their clinical benefit. The use of PRF does not require anticoagulants, bovine thrombin, or any other foreign materials or chemicals. This means that patients have nearly no risk of a foreign body reaction.
  • PRF has been shown to result in significantly faster healing. This process generates a fibrin network that leads to more efficient cell migration and faster cell regeneration.

Why Choukroun’s A-PRF?

Many recent studies have shown the interest and potential of white cells in the inflammatory cascade, as a corollary, a prominent action in the early days of stimulation of osseo-progenitor cells. (Omar & Thomsen, Biomaterials, 2012, Kawazoe T, Cell. Transplant 2012)

It was therefore natural to try to capture the whole amount of monocytes in the PRF, to 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 is done with the A-PRF or Advanced-PRF.

The concept of PRF (Platelet Rich Fibrin) is based on the centrifugation of whole blood without anticoagulants. (J. Choukroun et al. 2001). At the end of the spin, a fibrin clot containing the majority of the platelets and white blood cells is obtained.

This fibrin clot called Platelet Rich Fibrin or PRF will release gradually and growth factors or cytokines in the site (VEGF, PDGF, TGF Beta, Thrombospondin)

The expected objective of these growth factors is to accelerate the soft tissue and bone healing.

Numerous international publications (143) are available and demonstrate the effectiveness of PRF in many indications: oral surgery (implants, bone grafting, periodontal surgery, extractions, etc…), Orthopedic, cosmetic and dermatological surgery.

Today, the PRF is recognized around the world, from Nice to New York from Los Angeles to Shanghai, from Rangoon to Moscow, from Sao Paulo to Cape Town, Santiago to Zagreb…

Its effectiveness is definitely proven.
