Platelet Rich Fibrin (PRF)
PRF (Platelet Rich Fibrin) is one of the newest procedures in dentistry. This technology and technique allows dentists to use patients’ own cells to grow bone tissue. When a patient loses a tooth or bone due to periodontal disease, that bone can be grafted with bone that dentists buy from different companies which may be cow bone, cadaver bone or synthetic bone. However, such bone does not have the regular blood supply that a normal bone would have. This lack of blood supply could lead to delayed healing, infection and less integration of the grafted bone with the patient’s own bone. This problem has been solved with PRF. In many cases when using this technique, the platelet membrane can be used to signal the patient’s body to grow more bone; therefore, no outside bone is needed.
How does it work?
PRF procedure, as far as the patient is concerned, is very simple. The day of the surgery, the patient’s blood is drawn in the office. Then the plasma in the patient’s blood is separated. Plasma contains platelets and platelets consist of cell fragments and proteins. These cell fragments include a group of molecules that help with reducing inflammation and bleeding. This platelet portion will turn into a gel membrane which is held together by fibrins. This membrane can be placed in the implant area. In a case where outside bone is needed, this membrane from the patient’s own blood will provide white blood cells and proteins to reduce the risk of infection, inflammation, and bleeding. It also helps speed up the healing process and integration of the implant with the patient’s body.
