OBJECTIVES: Previous reports have revealed that several cytokines (including platelet-derived growth factor-BB, transforming growth factors-β1 and insulin-like growth factor-1) can enhance the rate of bone formation and synthesis of extracellular matrix in orthopaedics or periodontology. This study aimed to determine the concentration of cytokines within platelet-rich fibrin microstructures and...
Pseudoarthrosis, or nonunion, of the long bones is a challenging medical condition for orthopedic surgeons to treat. Therefore, healing enhancer materials are commonly used. The authors investigated whether platelet-rich fibrin accelerates long bone healing by comparing radiological and histological findings in a rat model of open femoral fracture. Platelet-rich fibrin is a current biomaterial ...
The development of novel regenerative material to reduce inflammation and enhance healing process is one the greatest task in clinical research. PRF ( platelet rich fibrin) an second generation concentrate which has gained popularity recent years due its unique process. Platelet Rich Fibrin completely autologous with extended growth factor release compared other concentrates. standard quality q...
Background: The purpose of this study was to create biomaterial scaffolds like platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) containing stromal cell-derived factor-1 (SDF1) as a chemokine to induce hyaline cartilage regeneration of rabbit knee in a full thickness defect.Methods: We created a full thickness defect in the trochlear groove of thirty-six bilateral knees of eighteen matu...
Background: Graft survival has been considered the major problem in reconstructive surgery. Clinical studies have helped us to understand the role of PRP in increasing skin survival. Our goal in this study was to examine the treatment effects of platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) on autologous full thickness skin graft survival in male rats. Methods: This experimental ...
Conclusion The platelet-rich plasmas failed to demonstrate significant benefits that justify the daily use, and the use of platelet-rich fibrin is limited to some very specific applications in which satisfactory results were achieved. Only a new simple, inexpensive and efficient technique such as the leucocyteand platelet-rich fibrin will continue to develop in oral and maxillofacial surgery in...
Platelet-rich fibrin (PRF) is a fibrin meshwork, in which platelet cytokines, growth factors, and cells are entrapped and discharged after a period and can serve as a resorbable film. PRF is the next generation of platelet concentrates equipped to improve arrangement without biochemical blood handling; PRF is an evolution of the fibrin adhesive, which is widely used in the oral surgery. The gui...
The topical use of platelet concentrates is recent and its efficiency remains controversial. Several techniques for platelet concentrates are available; however, their applications have been confusing because each method leads to a different product with different biology and potential uses. Here, we present classification of the different platelet concentrates into four categories, depending o...
