PRF — platelet-rich fibrin — is used in implant dentistry because it accelerates the biological processes that determine how quickly and reliably healing occurs. Understanding what PRF actually does — not just that it “improves healing” — helps patients evaluate whether it is appropriate for their case and ask the right questions.
What PRF Is
PRF is an autologous biomaterial: it is made from the patient’s own blood, drawn immediately before the procedure. The blood is centrifuged to separate its components. The middle layer contains a fibrin clot rich in platelets, leukocytes (white blood cells), and the growth factors these cells release. This clot — the PRF membrane — is what is applied to the surgical site.
Because it is derived entirely from the patient’s own blood with no additives, anticoagulants, or external biological materials, there is zero risk of allergic reaction or rejection. The preparation takes approximately 10–15 minutes from blood draw to membrane.
The Active Biology: Growth Factors That Matter
The three most clinically significant growth factors: PDGF stimulates osteoblast and fibroblast proliferation, drives new bone formation and angiogenesis; TGF-β regulates cell proliferation and collagen synthesis, reduces excessive inflammation; VEGF drives angiogenesis at the surgical site bringing the oxygen and nutrients that regenerating tissue requires. The fibrin matrix itself functions as a bioactive scaffold. For a comprehensive guide to different PRF types, see our PRF applications article.
Where PRF Is Used at Dazzle Dental Clinic
Implant placement sites: Applied around the implant to promote early osseointegration. Particularly valuable in soft bone (Misch Type III–IV) where biological support for integration is more critical.
Bone graft sites: PRF is mixed with particulate graft material to bind it, retain it in the defect, and accelerate its integration. This is its most consistently documented benefit — PRF combined with bone graft outperforms bone graft alone in most published studies measuring bone density at 6 months.
Sinus lifts: Placed within the elevated sinus membrane to promote new bone formation in the sub-sinus space. The combination of PRF and xenograft material in sinus lifts consistently reduces the healing period before implant placement.
Extraction sockets: Placed after tooth extraction to maintain ridge volume and accelerate socket healing. PRF reduces post-extraction pain and swelling in addition to its regenerative effects.
Soft tissue grafting: Used in conjunction with connective tissue grafts for peri-implant tissue augmentation and gingival recession coverage.
When PRF Adds Genuine Value vs. When It’s Routine
PRF is not used as a routine add-on at Dazzle — it is integrated where the clinical evidence supports meaningful benefit. Straightforward single implants in dense, healthy bone in medically uncomplicated patients may not require PRF, and we don’t add it automatically.
FAQs
Q1: Does PRF hurt? Is blood drawing required on the day of surgery?
Yes — a small blood sample is drawn at the clinic immediately before the procedure. This is a straightforward venepuncture, similar to a routine blood test. Processing takes 10–15 minutes and occurs while other pre-surgical preparations are being made.
Q2: Is PRF safe for patients with blood conditions?
PRF is derived from the patient’s own blood, so there is no external biological material risk. Patients with clotting disorders or on anticoagulant therapy require individual assessment. For most patients there are no contraindications.
Q3: Does PRF cost extra?
There is a preparation cost associated with PRF that reflects the centrifuge protocol and clinical time involved. At Dazzle, cases where PRF is recommended are quoted with PRF included; it is not added as an uncommunicated line item.
Q4: What is the difference between PRF and PRP?
Both are platelet concentrates derived from the patient’s blood. PRP requires anticoagulants to remain liquid. PRF is entirely natural without additives. The fibrin matrix in PRF releases growth factors more slowly and sustainably than PRP, which is considered a clinical advantage. PRF has largely replaced PRP in implant dentistry at centres using current protocols.
