Your Kit Contents
Everything you need to prepare and apply PRF in your clinical setting — from centrifuge to hand instruments.
PRF Centrifuge
Preset settings for A-PRF and i-PRF. Good results staying on A-PRF settings for both.
Tubes
24× S-PRF (green) for sticky bone. 100× A-PRF (red) for plugs and membranes.
Vacutainers
35× 21G Butterflies. Smaller diameter needles are less painful but more destructive to blood cells.
Hand Instruments
Rat-tooth forceps, graft scoop, graft packer, and transportation pad.
PRF Centrifuge
Preset Programs
The centrifuge has preset ideal settings for both A-PRF (plug and membrane) and i-PRF (sticky bone). We have found good results staying on A-PRF settings for both applications.
Tubes
S-PRF — Green Tubes
24× 10ml tubes. Used for producing i-PRF for sticky bone preparation.
A-PRF — Red Tubes
100× 10ml tubes. Produce PRF plugs which can also be flattened into membranes.
Vacutainers & Tube Rack
35× 21G Butterflies
Smaller diameter needles (22G and 23G) are less painful but more destructive to blood cells. 21G is the recommended gauge.
Tube Rack
Used to keep centrifuged tubes upright after spinning to preserve the separated layers before use.
PRF Press Box
Used to compress PRF plugs into flat membranes for use in GBR and other applications.
PRF Trays & Hand Instruments
PRF Trays
Flat tray for flat membranes. Rounded tray for sticky bone mixing.
Hand Instruments
  • Rat-tooth forceps — for removing the slug from the tube
  • Graft scoop
  • Graft packer
  • Transportation pad
PomPac Cooler
Why Use the PomPac?
A colder tube will produce more PRF. The PomPac can be kept in the freezer and tubes can be cooled inside it prior to blood draw, maximizing PRF yield.

The PRF Plug — Socket Preservation
Draw 1–2 A-PRF tubes per socket, remembering to spin counterbalanced. Form the plug and deliver it into the socket.

PRF Plug — Clinical Evidence
"The results showed an acceptable efficacy for PRF without graft materials in alveolar ridge preservation. This material is cost-effective and could be easily prepared. PRF application in extraction sockets yielded similar results to FDBA."

Socket Preservation — Histomorphometric Study
A randomized controlled trial of 90 patients compared FDBA+PRF membrane, PRF alone, and a control group. Implants were placed 4 months post-extraction with bone biopsies analyzed for vital bone and connective tissue.

63.29%
FDBA + PRF Membrane
Vital bone formation (±13.03%)
90
Patients
Randomized across 3 groups
Ivanova et al. — Both test groups showed significantly higher vital bone formation vs. control. No statistically significant difference between PRF alone and FDBA+PRF. PMID: 34299902
A-PRF vs. FDBA — Randomized Controlled Trial
40 patients requiring extraction and implant replacement were randomized into four ridge preservation groups: A-PRF, A-PRF+FDBA, FDBA, or blood clot. A-PRF was prepared at 1,300 rpm for 8 minutes. Bone cores were harvested after ~15 weeks.
Ridge Height Loss
Blood clot: 3.8 ± 2.0 mm vs. A-PRF: 1.8 ± 2.1 mm vs. A-PRF+FDBA: 1.0 ± 2.3 mm (p < 0.05)
Vital Bone
A-PRF: 46% ± 18% vs. FDBA: 29% ± 14% (p < 0.05) — significantly more vital bone with A-PRF
Bone Mineral Density
FDBA: 551 ± 58 mg/cm³ vs. blood clot: 487 ± 64 mg/cm³ (p < 0.05)

The PRF Plug — Wisdom Tooth Sockets
Pain & Analgesia
Significantly decreases post-op pain and reduces analgesic intake on days 3 and 7.
Edema & Trismus
Reduces post-operative edema and trismus, with statistically significant results at day 3 and 7 (p < 0.05).
Soft Tissue Healing
Improved soft tissue healing and reduced dry socket risk. Reduced hematomas and skin warmth on day 3.
Bone Density
Increased bone density in the socket. A-PRF was more important than tooth position or procedure duration in reducing complications.
Wisdom Tooth Study — Key Findings
A study of 100 patients undergoing lower third molar odontectomy (Gdańsk, 2018–2019) compared 50 patients with immediate A-PRF socket filling vs. 50 controls. Clinical features were assessed on days 3, 7, and 14.

A-PRF growth factors reduce postoperative complications — pain, trismus, edema, analgesics intake, hematomas, and skin warmth — after mandibular wisdom teeth odontectomy.
Chapter 3
The PRF Plug — Indirect Sinus Lift
If there was a way to lift the membrane and leave it lifted without graft — it would fill with bone. Using bone graft particles carries risk: what do you do if it migrates into the sinus? The PRF plug offers a safer alternative.
Chapter 4
The PRF Plug — Direct Sinus Lift
PRF as the sole filling material during lateral sinus lift with immediate implantation. Study by Mazor et al. — 25 sinus elevations on 20 patients, 41 implants placed in residual bone height of 1.5–6 mm (mean 2.9 ± 0.9 mm).

Sinus Elevations

"PRF as the sole filling material stabilized a high volume of natural regenerated bone in the sub-sinus cavity up to the tip of the implants. A simple and inexpensive biomaterial." — Mazor et al., J Periodontol 2009
Direct Sinus Lift — Surgical Views
Direct Sinus Lift — Intraoperative & CBCT
Intraoperative view (F): PRF plug inserted into the sinus cavity.
CBCT (G): Pre- and post-operative sagittal views showing sinus floor elevation.
Direct Sinus Lift — Pre & Post CBCT
Pre-operative (A): Right maxillary sinus. Sinus floor at approximately the 30mm mark.
Intraoperative (B): Implant placed with PRF plug visible in the sinus cavity.
Post-operative (D): Sinus floor now at ~40mm — successful elevation confirmed.

Creating the PRF Membrane
PRF Membrane — Plugs to Membranes
PRF plugs prior to pressing — yellowish fibrin matrix with reddish base.
Resulting PRF membranes after pressing — flattened, rich in platelets and growth factors.
PRF Membrane — GBR Application
PRF membranes can be placed over collagen membranes to improve tissue healing efficiency in Guided Bone Regeneration procedures.
PRF Membrane — Implants (Poncho Technique)
Use the poncho technique to support your implant tissue results. The PRF membrane is draped over the implant and surrounding gingiva to promote healing.

Sticky Bone — Preparation Protocol
Sticky Bone — Step by Step
A: Draw S-PRF from green tube into syringe over bone graft.
B: Pour S-PRF into bowl and mix with bone graft.
C: Mixed S-PRF and graft — reddish color from fibrin.
D: Sticky bone formed — graft coated in fibrin matrix.
