**Abstract**

Platelet-rich fibrin (PRF) as a biological scaffold is attracting clinicians' attention, mainly because it promotes bone and soft tissue healing. As autologous material, PRF has many advantages over other platelet concentrates, such as Platelet-rich plasma (PRP) and Plasma rich in growth factors (PRGF). Among many benefits, simple preparation (centrifugation protocol) stands out because no additional anticoagulant is added to the tubes. This chapter aims to clarify the PRF membranes and sticky bone preparation together with other platelet concentrates. A few clinical cases will show how sticky bone is together with PRF membranes applicative in different oral surgery indications. Clinical and radiological check-ups demonstrated excellent therapeutic outcomes. Sticky bone and PRF membranes have regenerative potential and are advised to use in many oral surgery procedures.
