Abstract
The use of platelet concentrates has had a long history of use in various fields of medicine as an autologous source of growth factors fabricated utilizing centrifugation of blood under various conditions. While platelet-rich plasma (PRP) was proposed as a first-generation platelet concentrate over 3 decades ago, over the past 10 years, platelet rich fibrin (PRF) has seen a steady increase in utilization for a variety of medical procedures due to its lack of anti-coagulation factors favoring fibrin clot formation and faster wound healing. More recently, further research has demonstrated that shorter and slower centrifugation spin cycles (‘the low-speed concept’ now termed advanced-PRF, A-PRF+) additionally favors wound healing by incorporating higher populations of white blood cells and progenitor cells within the PRF fibrin matrix leading to higher growth factor release within the local microenvironment. Parallel to these findings, the development of a liquid injectable PRF (i-PRF) provides a new formulation of liquid PRF without using anti-coagulation factors that may specifically be combined with currently available bone biomaterials favoring particle stability, angiogenesis and tissue integration. This course aims to highlight the recent advancements made with respect to the newest formulations of platelet concentrates and systematically presents when, where and why specific platelet concentrates may be utilized to further speed wound healing and tissue regeneration for various clinical indications faced in routine daily dental practice.
