Clinical application of platelet-rich fibrin by the application of the Double J technique during implant placement in alveolar bone defect areas: case reports.

Platelet-rich fibrin (PRF) belongs to a new generation of platelet concentrates, with simplified processing and without biochemical blood handling. PRF releases growth factors and matrix glycoproteins. In this study, the Double J technique was used. The Double J technique, which uses centrifuged venous blood that is sampled using 2 different types of DB vacutainers, is a procedure that covers the PRF matrix obtained from 1 of the DB vacutainers on transplanted osseous coagulum, which is obtained using the plasma layer and buffering layer from the second DB vacutainer. Two cases were reported because clinically valid results were obtained. Additional studies are definitely warranted.
