PRF (Platelet-Rich Fibrin)
Biological Dentistry
PRF (Platelet-Rich Fibrin)
PRF (Platelet-Rich Fibrin) is a completely natural and autologous (derived from the patient’s own body) biomaterial obtained from the patient’s own blood and prepared without the use of any chemical additives or anticoagulants. It is produced by concentrating the platelets, white blood cells, and growth factors in the blood within a fibrin matrix. In dentistry, it is widely used to accelerate healing, particularly in procedures such as implant placement, tooth extraction, bone grafting, and periodontal surgery.
The main purpose of PRF application is to accelerate the healing process following surgery or implant placement and to support tissue and bone regeneration.
When placed in the treatment area, the fibrin matrix, which contains a high concentration of growth factors, activates the body’s own repair mechanisms. This helps reduce pain, swelling, and healing time.
Biological Dentistry
Who Is It Suitable For?
- Patients undergoing dental implant placement,
- Patients who wish to accelerate socket healing after tooth extraction,
- Patients who will undergo bone grafting or sinus lifting procedures,
- Patients undergoing periodontal (gum) surgery,
- Patients who prefer natural, chemical-free healing support and embrace the biological dentistry approach,
- Patients whose wound healing is slow or who need additional support.
Biological Dentistry
Who Is It Not Suitable For?
- Patients with blood clotting disorders or those taking strong anticoagulant (blood-thinning) medications require careful evaluation.
- In patients with an active infection or an uncontrolled systemic disease, the existing condition must be treated first.
- In patients with severe bleeding disorders, certain blood diseases, or platelet function disorders, the application must be reassessed by the dentist.
Patients with medical conditions that prevent blood collection.
Biological Dentistry
Advantages
- Since it is obtained from the patient’s own blood, the risk of allergic reactions or rejection is almost nonexistent.
- It contains no chemical additives or anticoagulants and is completely natural.
- It reduces pain, swelling, and post-operative discomfort.
- It accelerates soft tissue and bone healing and has a supportive effect on implant and graft success rates.
- It can be prepared quickly and applied during the same session.
Biological Dentistry
Potential Risks
- Mild bruising, swelling, or temporary tenderness at the application site may occur as a result of blood collection.
- In rare cases, there may be a risk of infection at the blood collection site.
- Careful application is required in patients with bleeding disorders.
- The effectiveness of PRF may vary depending on the patient’s general health, age, and healing capacity.

Treatment Process
Blood Collection: A small amount of blood is drawn from the patient, just as it would be during a standard blood test.
Centrifugation: The collected blood is spun in a special centrifuge for a few minutes to separate the platelets and fibrin from the red blood cells.
PRF Membrane Preparation: The resulting fibrin clot is transformed into a membrane or gel.
Application: PRF is placed in the implant cavity, extraction socket, graft site, or surgical area. It is generally applied simultaneously with the procedure performed under local anesthesia.
Closure: The treatment area is closed using standard surgical techniques.
The time from blood collection to PRF preparation and application is generally 10–20 minutes. PRF preparation is carried out simultaneously with the main surgical procedure (implant placement, tooth extraction, grafting, etc.), rather than being added to its duration. Therefore, it does not significantly extend the total procedure time.
The positive effects of PRF application begin to be felt within the first few weeks. A noticeable reduction in pain and swelling is generally observed from the first few days. The full effects on tissue and bone regeneration usually become apparent within 2–3 months.
The healing process may vary depending on the type of procedure performed (implant placement, grafting, extraction, etc.) and the patient’s individual healing capacity.

Post-Treatment Care Instructions
Hard and very hot foods should be avoided during the first 24 hours after the procedure. Mild bruising at the blood collection site is normal and will disappear on its own within a few days. The oral care instructions recommended by the dentist (such as gentle brushing and mouthwash use) should be followed. Smoking and alcohol should be avoided for a few days after the procedure, if possible, as they may slow down the healing process. In case of severe pain, persistent bleeding, or signs of infection (fever, excessive swelling), the dentist should be contacted. Regular follow-up appointments should be attended.
