What does “PRF” mean?
PRF stands for platelet-rich fibrin, a material containing platelets obtained by centrifuging the patient’s own blood. In dentistry, it is used as an adjunct to support healing at extraction or surgical sites.
A blood-derived material used to support healing
Centrifuging a blood sample can produce a fibrin structure containing platelets and other components. Different forms, including solid and liquid preparations, may be used at the required site. The material should be distinguished from a product or device brand.
Evidence differs by purpose
The German 2022 S3 guideline discusses filling an extraction socket, the space left after tooth removal, with solid PRF as an option for preserving ridge volume. This does not amount to a guarantee of success for every bone defect or implant operation. For immediate implant placement, differences in research methods and limited evidence also need consideration.
It does not replace basic surgery and care
Necessary cleaning, an appropriate surgical plan, and wound care remain important when PRF is added. Whether bone graft materials or membranes are also needed depends on the defect and treatment goals. PRF use alone does not establish that other procedures are unnecessary.
Frequently Asked Questions
Does PRF guarantee that an implant will integrate successfully?
No. Supporting early healing is different from demonstrating long-term osseointegration or implant retention. Bone and general health, surgical and prosthetic planning, and ongoing care remain important.
Can PRF replace bone graft materials?
In some situations requiring ridge preservation after extraction, filling the socket with solid PRF alone may be considered. However, this does not replace all bone grafting. Other materials or procedures may be needed depending on the extent of the tissue deficiency and the treatment goal.
