Concentrated PRF (C-PRF)

C-PRF is a platelet-rich fibrin variant in which the upper plasma layer is fractionated to isolate the fraction with the highest platelet and leukocyte concentration, rather than using the whole liquid layer.

In practice

C-PRF is a preparation technique rather than a machine capability. It requires careful, layered pipetting and is therefore more sensitive to operator skill than most protocols.

Injectable PRF (i-PRF)i-PRF is a liquid form of platelet-rich fibrin prepared at low centrifugal force and short duration, which leaves it injectable before it clots.
