About this study

This research will be a randomised controlled trial (RCT) investigating whether the use of Horizontal Platelet Rich Fibrin (H-PRF) increases implant stability compared to those implants placed without H-PRF, and therefore, contributes to the implant's overall success. H-PRF is a second generation platelet concentrate that consists of a fibrin mesh containing cytokines and leukocytes. It has been shown to stimulate mesenchymal stem cells and osteoblasts that encourage bone formation as a result of the growth factors released from platelets, which should aid in osseointegration of implants. There is limited research that investigates the effects of H-PRF on implant stability. There is, however, some evidence that platelet-rich fibrin (PRF), which is produced in a fixed-angle centrifuge, increases implant stability and H-PRF is considered the evolution of PRF products. This research would follow a H-PRF preparation protocol which involves taking a sample of venous blood from patients using a butterfly needle to collect up to 8-9ml tubes of blood. After the tube of blood is collected, it would immediately be placed in a horizontal centrifuge machine with 3 tubes of water to balance the centrifuge, and placed opposite each other. A set rpm and time will be chosen, and the centrifuge will run until the time is complete. The H-PRF clots would then be ready and taken out of the tubes to separate them from the red blood cells. Following randomisation, implants will be placed in the…
