Bilateral direct sinus lift with platelet rich fibrin (PRF) in combination with DFDBA and FDBA: a case report
نویسندگان
چکیده
Platelet rich fibrin (PRF), developed in France by Choukroun et al(2001), is a second generation platelet concentrate widely used to accelerate soft and hard tissue healing. It’s advantages over the better known platelet rich plasma (PRP) include ease of preparation & application, minimal expense and no need of biochemical blood handling (no bovine thrombin or anticoagulants required). This article describes the use of PRF in bilateral direct sinus lift case. Around 20 ml of blood is collected from the patient for each side procedure in the vacutainer tubes and then placed immediately before the coagulation cascade begins in a centrifugal machineat 3000 rpm for 10 min and the middle fraction containing the fibrin clot is then collected to obtain the PRF. Sinus cavities after lifting the membrane was filled with PRF in combination with DFDBA and FDBA. The post-operative radiograph showed faster healing as compared to physiologic healing. However, the preparation being strictly autologus, the amount of PRF obtained is limited.

OBJECTIVE Platelet-rich fibrin (PRF) belongs to a new generation of platelet concentrates, with simplified processing and without biochemical blood handling. The use of platelet gel to improve bone regeneration is a recent technique in implantology. However, the biologic properties and real effects of such products remain controversial. In this article, we therefore attempt to evaluate the pote...

Introduction: The healing process after surgery is a challenging issue for surgeons. Various materials and techniques have been developed to facilitate this process and reduce its period. Fibrin adhesives are often used in cardiothoracic and vascular surgery to seal diffuse microvascular bleeding and in general and plastic surgery to seal wound borders. This Case report and literature review ...
