PRP (Platelet-Rich Plasma), first used in traditional medicine in the 1980's and in dentistry in the 1990's, is a new approach to tissue regeneration and is becoming a valuable adjunct to promote healing in many dental procedures. If you've even casually followed sports in the last 10-15 years, no doubt you have heard about plasma-rich plasma injections. The treatment has been used across physical therapy and orthopedics to accelerate the healing time for muscle, joint, ligament, and bone injuries.
According to Dr. Gerald Imber, M.D. in Mens Journal, here's how it works. Blood contains several substances: white and red cells, plasma, and tiny cells called platelets, which are critical in blood clotting and wound healing. (The healing elements are also called growth factors). Two decades ago, we learned that when platelet growth factors are collected and concentrated, then injected into a wound, the healing time is appreciably faster.
In PRP therapy, the patient’s own blood is drawn out and then spun rapidly, resulting in a concentration of platelets. When this heavily concentrated portion of the blood is isolated it contains three to five times the number of growth factors found in normal blood.
PRP has proven to be effective in aiding several oral and maxillofacial surgical procedures. There is also evidence showing PRP therapy as a promising aid in periodontal regenerative therapy. PRP therapy helps in bone grafting, a procedure used to improve the outcome of dental implant surgery. PRP can also be used in the repair of bone defects in the wake of tooth or cyst removal and the repair of fistulas between the sinus cavity and the mouth.
In the dental profession, there is tremendous value placed on fast healing. PRP may help optimize the conditions for healing of bone and soft tissue. The faster a patient heals following surgery, the lower the risk of infection and other complications.
