Autologous Platelet Gel and PRF in Implant Dentistry

The biology of healing is the part of implant dentistry that the surgeon never fully controls. We can position the implant, contour the flap, and select the graft material — but the cellular response that determines whether the site integrates or fails belongs to the patient.

Autologous platelet concentrates — PRP, PRGF, PRF, and their variants — are an attempt to nudge that biology. Drawn from the patient's own blood and concentrated by centrifugation, they deliver a high local dose of growth factors at the surgical site at the moment they are most useful.

The clinical evidence is most consistent in three domains: socket preservation after extraction, soft-tissue healing after flap surgery, and sinus augmentation. The evidence is more mixed for routine implant placement in healthy bone, where the baseline healing response is already adequate.

What the concentrates are not is a workaround for poor case planning, inadequate bone volume, or systemic risk factors. They reduce friction in healing — they do not rewrite the biology of a compromised host.
