Platelet Rich Fibrin (PRF)
Platelet-rich fibrin (PRF) is a by-product of blood that is rich in platelets. Until now, its use has been confined to the hospital setting. This was due mainly to the cost of separating the platelets from the blood and a large amount of blood needed to produce a suitable quantity of platelets. New technology permits doctors to harvest and produce a sufficient quantity of platelets from a small amount of blood, which is drawn from the patient while they are having outpatient surgery.
Why All The Excitement About PRF?
Platelet Rich Fibrin permits the body to take advantage of the normal healing pathways at a greatly accelerated rate. During the healing process, the body rushes many cells and growth factors to the wound in order to initiate the healing process. Platelets assist information of a blood clot and release of growth factors which stimulate stem cells to regenerate new tissue. The more growth factors released and sequestered into the wound, the more stem cells are stimulated to produce new tissue. Thus, PRF permits the body to heal faster and more efficiently.
- Faster healing: The surgical site is supersaturated growth factors that produce an increase in tissue synthesis and faster tissue regeneration.
- Safety: PRF is a by-product of the patient’s own blood, therefore, disease transmission is not an issue.
- Convenience: PRF can be generated in the doctor’s office while the patient is undergoing an outpatient surgical procedure such as the placement of dental implants.
- Cost-effectiveness: Since PRF harvesting is done with a small amount of blood in the doctor’s office, the patient need not incur the expense of the harvesting procedure in a hospital or at a blood bank.
- Ease of use: PRF is easy to handle and actually improves the ease of application of bone substitute materials and bone grafting products by making them more gel-like.
PRF Has Many Clinical Applications
PRF can be used to aid bone grafting for dental implants. By adding PRF to the implant site with bone substitute particles, the implant surgeon can now grow bone more predictably and faster than ever before. Its application includes but is not limited to bone grafts, sinus lift procedures, ridge augmentation procedures, closure of cleft and/or lip, and palate defects. It can also assist in the repair of bone defects created by the removal of teeth, or small cysts and the repair of fistulas between the sinus cavity and mouth.
Frequently Asked Questions About PRF
Is PRF safe? Yes. During the surgical procedure, a small amount of your own blood is drawn out via the IV. This blood is then placed in the PRF centrifuge machine and spun down. In less than 15 minutes, the PRF is formed and ready to use.
Should PRF be used in all bone-grafting cases? Not always. In some cases, there is no need for PRF. However, in the majority of cases, the application of PRF to the graft will increase the final amount of bone present, in addition to making the wound heal faster and more efficiently.
Will my insurance cover the costs? Unfortunately not. The cost of the PRF application is paid by the patient. The cost will be minimal to the patient.
Can PRF be used alone to stimulate bone formation? No. PRF must be mixed with either the patient’s own bone, a bone substitute material such as demineralized freeze-dried bone, or a synthetic bone product, such as BIO-OSS.
Are there any contraindications to PRF? Very few. Obviously, patients with bleeding disorders or hematologic diseases do not qualify for this in-office procedure. Check with your surgeon and/or primary care physician to determine if PRF is right for you.
