“Bone grafting with your own blood” sounds unusual at first. Behind it is a method that makes use of the body’s natural wound healing: a concentrate rich in platelets and growth factors is obtained from your blood – platelet-rich fibrin, or PRF for short.

In short

PRF is obtained from a small amount of your own blood by centrifugation – without any additives. The resulting fibrin gel can be mixed with bone substitute material or placed on wounds as a membrane. It is considered very well tolerated and can support the healing of wounds and soft tissue.

## How PRF is produced

PRF 
1. **Blood sample**a few tubes from a vein in the arm, directly before the procedure.
2. **Centrifugation**The blood is spun for a few minutes and separates into layers.
3. **Fibrin concentrate**The middle layer with fibrin, platelets and white blood cells is drawn off.
4. **Application**as a gel mixed with bone substitute (“sticky bone”) or pressed into a membrane.

The fibrin concentrate is prepared immediately before the procedure.

## What PRF is used for

- filling tooth sockets after extractions (socket preservation)
- guided bone regeneration around implants
- sinus lift
- covering wounds, e.g. after wisdom tooth removal

## What PRF can – and cannot – do

PRF is not a “miracle cure” but a useful addition: studies suggest that it can improve soft tissue healing and reduce swelling. The actual bone building is still done by the grafting material or your own bone. We use PRF where, according to current knowledge, it offers an advantage.

Is PRF paid for by health insurance?

No, preparing PRF is a private service that you pay for yourself.
