The use of platelet-rich fibrin has gained importance as an autologous scaffold for tissue regeneration. One of its features is, when placing implants in fresh extraction sockets, to function as a selective scaffold and also as a barrier in order to correct marginal bone defects and/or to avoid collapse of surrounding soft tissue. However, its handling and placement require specific manipulation skills, to avoid unintentional slipping and dislodging during the suture procedure. In order to avoid these problems and to allow easier and faster use of the PRF matrix, a simple device for providing a self-stabilized fibrin plug has been developed. This plug surrounds, as an elastic ring, the transmucosal extension of the prosthetic components for conical internal connection implants, thus enhancing the effectiveness of the fibrin matrix expected performance.
