Injectable Platelet-Rich Fibrin (i-PRF) is an innovative, autologous biomaterial derived from a patient's own blood, used to promote tissue healing and regeneration. Unlike traditional platelet concentrates, i-PRF is produced without anticoagulants, leading to a fibrin matrix that naturally holds a high concentration of platelets, growth factors, and cytokines. When injected, this fibrin matrix releases bioactive molecules gradually, enhancing cellular proliferation, angiogenesis, and collagen production in target tissues. i-PRF has been widely applied in various medical fields, including dentistry, orthopedics, and dermatology, offering a minimally invasive, biocompatible method to support wound healing, bone regeneration, and soft tissue repair. Its use underscores a biological approach that harnesses the body's intrinsic healing capabilities, making it a promising adjunct in regenerative medicine.
