Lecture abstract:

Leucocyte- and platelet-rich fibrin (L-PRF), a second generation platelet concentrate, is an autologous blood derived product, which can be obtained, quickly and at low cost.  L-PRF is produced from peripheral blood, which is immediately centrifuged without any anticoagulant.  L-PRF is rich in fibrin, platelets (± 95% of initial blood) and leucocytes (± 50% of initial blood), an can be transformed into strong membranes circa 1 mm in thickness.  L-PRF membranes releases large amounts of growth factors for a long period (up to 7 days).  They remain intact for more than 7 days due to a specific polymerization and architecture of the fibrin matrix, and they possess antibacterial effects.L-PRF membranes offer “significant” and “clinically relevant” advantages in case of: sinus augmentation, ridge preservation, initial osseointegration, soft tissue grafting, etc.…  This presentation will show scientific data in order to underline the clinical benefits.  It will also include clear guidelines (step by step procedures) for clinical use L-PRF in most relevant situations.
