Platelet-rich plasma (PRP) was mixed with thrombin and excess calcium resulting in activated platelets trapped within the fibrin network; within the matrix, platelets secrete bioactive substances that diffuse into the surroundings tissues. PRP is prepared from the patient’s own blood, a variety of manufacturing techniques in vastly different cell counts, and growth factor concentrations. The clinical use of PRP is treatment of soft tissue diseases and injuries, treatment of burns, hard-to-heal wounds, tissue engineering, and implantology in dentistry. An essential criterion for PRP is for it to be autologous, for the donor of the blood, and the recipient of the PRP to the same person. Most of the literatures suggest that PRP does not appreciably impact bone healing or induce bone formation. PRP might augment recruitment of osteoblast progenitors to injection sites or in sites expected to experience delayed healing. In this capacity, PRP might be utilized to initiate repair of an otherwise poorly healing bony lesion. PRP stimulates bone repair in fractures. Early through late healing process is compromised with fractures, including reduced cell proliferation, delayed chondrogenesis, and decreased biomechanical properties. In this chapter, the importance of the PRP in oral and maxillofacial surgery in trauma patients is studied
