Platelet-rich fibrin (PRF) is something we like not only for how it supports healing after oral surgeries but also because it comes from you. No foreign material. Nothing synthetic. Just a concentrated portion of your own blood that’s loaded with things your body uses as it repairs itself: a fibrin matrix enriched with platelets and leukocytes, which release growth factors involved in healing.
Fibrin is the protein that helps form a clot and provides a kind of scaffold for new tissue.
Studies suggest that PRF helps speed up the healing process, as well as reduce post-op pain and discomfort. Here in our office, we use it in many surgical procedures, including extractions and the placement of zirconia implants.
Much of the research on PRF and dental implants has focused largely on matters of stability. That makes total sense, of course. Osseointegration — the fusing of the implant with the bone it’s set in — is crucial for long-term implant success. Without enough healthy, good quality bone to support it, an implant may not last.
But the health and response of the soft tissues around the implant matter, too.
A natural tooth has an entire support system built around it: bone, gums, connective tissues, and the periodontal ligament, which helps anchor the tooth while also acting as a kind of shock absorber and providing sensory feedback about pressure and movement.
Dental implants work differently. Though they don’t have a periodontal ligament, they still depend on healthy surrounding tissues for long-term support and protection — a point we’ve touched on briefly before.
How the soft tissues respond to implant placement was the focus of a systematic review and meta-analysis that was recently published in Odontology.
So in order “to assess the effect of platelet-rich fibrin (PRF) on soft tissue augmentation around dental implants,” researchers turned to studies that compared implants placed with PRF to those placed without it, paying particular attention to measurements related to soft tissue healing and health around the implant.
Thirteen studies involving 264 patients made the cut. Analysis found that adding PRF to implant placement improved early soft tissue healing compared to the tissues around implants placed without it. Patients receiving PRF tended to develop thicker, healthier gum tissues during the first three months after treatment, suggesting a better healing environment.
That’s part of the reason there’s growing interest in the quality of the “seal” formed by the soft tissues around an implant. Healthy gum tissue may help reduce irritation, limit bacterial infiltration, and support the long-term health of the area overall.
While longer-term studies are still needed, the findings of this review reinforce the concept that PRF may offer meaningful benefits during the critical early healing phase. Taken together with earlier research on implant mobility and healing, they point toward what many biological dentists have already seen clinically: Supporting the body’s healing response matters.
Of course, successful treatment of any kind involves many factors working together, influenced by the individual’s unique health history and current health situation. Implant surgery requires careful planning, healthy bone and gum tissue, good surgical technique, and appropriate home care afterward. The details can vary from patient to patient, which is why each treatment plan we write is customized to the individual’s needs.
Still, research like this helps explain why we continue to use PRF in the surgical procedures we do. We prefer to support healing with materials the body already recognizes as its own.
