Platelet-rich fibrin

Platelet-rich fibrin (PRF) or leucocyte- and platelet-rich fibrin (L-PRF) is a second-generation PRP where autologous platelets and leucocytes are present in a complex fibrin matrix^[1][2] to accelerate the healing of soft and hard tissue^[3] and is used as a tissue-engineering scaffold for endodontics.^[4]

Dentistry

Socket preservation

Socket preservation, a procedure to reduce bone loss after tooth extraction to preserve the dental alveolus (tooth socket) in the alveolar bone. A platelet-rich fibrin (PRF) membrane containing bone growth enhancing elements can be stitched over the wound or a graft material or scaffold is placed in the socket of an extracted tooth at the time of extraction. The socket is then directly closed with stitches or covered with a non-resorbable or resorbable membrane and sutured.

Sinus lift

A platelet-rich fibrin can be used if a sinus lift is required for a dental implant.^[5][6]

Guided bone and tissue regeneration

PRF is used in guided bone and tissue regeneration^[7]

Regenerative endodontics

PRF enhances alveolar bone augmentation^[8] and necrotic dental pulp and open tooth apex can be revitalized in regenerative endodontics with platelet-rich fibrin.^[9]
