Dr. Choukroun’s Ocean™ PRF Processing Cassette
Dr. Choukroun’s Ocean™ PRF Processing Cassette
Dr. Choukroun’s Ocean™ PRF Processing Cassette is a dedicated chairside press box workstation designed for the controlled processing of A-PRF™ clots and S-PRF™ plasma. Engineered to standardize PRF preparation, it enables clinicians to efficiently produce A-PRF™ membranes, plugs, ponchos, and S-PRF™ sticky bone within a single organized system.
Beyond instrument storage, the PRF Ocean™ functions as a structured PRF processing platform. It supports PRF handling in both liquid form (S-PRF™) and solid clot form (A-PRF™), allowing precise manipulation, compression, and combination of autologous components during regenerative procedures.
The integrated layout allows secure positioning of PRF tubes, organized staging of surgical instruments, uniform compression of A-PRF™ clots into membranes, controlled formation of plugs and ponchos, and predictable mixing of S-PRF™ with particulate graft material to produce cohesive sticky bone. The result is a streamlined, reproducible workflow that enhances procedural efficiency and biologic control in implant and grafting cases.
PRF Ocean™ Cassette Component Overview
1- PRF Processing Tray
Primary working surface for A-PRF™ and S-PRF™ preparation
1A. A-PRF™ Press Tray
Designed to compress A-PRF™ clots into uniform membranes
1B. S-PRF™ Sticky Bone Compartment
Dedicated mixing chamber for combining particulate graft material with S-PRF™ plasma and exudate to form sticky bone
1C. A-PRF™ Plug Forming Cylinders
Four cylindrical chambers for shaping A-PRF™ clots into plugs
1D. PRF Plug Piston
A weighted compression cylinder used to create pressure during A-PRF™ plug formation in section 1C
2.- PRF Ocean™ Cassette Housing
Encases the processing tray, allows tubes to be stored during processing, and houses PRF instruments for sterilization.
2A. Integrated Tube Holders
Tube holders are built into the cassette body, eliminating the need for an external tube holder.
2B. Hand Instrument Storage Inserts
Silicon inserts are integrated into the cassette, which allows instruments such as graft packers or tweezers to be stored when not in use.
2C. Scissor Storing Clip
A scissor-holding clip is integrated into the lid of the cassette, which allows a scissor to be stored in the open position during sterilization.
How to Produce S-PRF™ Sticky Bone Using the PRF Ocean™
- Centrifugation
Centrifuge the green and red tubes according to the protocol sheets provided under Dr. Choukroun’s guidelines.
- Tube Placement
After centrifugation, place both green and red tubes into Section 2A, the designated tube holders within the cassette. Allow the red tubes to remain upright with caps removed for a minimum of five minutes to complete coagulation before clot retrieval.
- Prepare the Graft Base
During the coagulation period, dispense the selected particulate grafting material into Section 1B. Irrigate S-PRF™ plasma from the green tubes into the particulate and gently blend to initiate hydration.
- Clot Processing
Once coagulated, remove each A-PRF™ clot from the red tubes using sterile tweezers. Excise the red blood cell fraction from the base of each clot with surgical scissors to isolate the fibrin portion.
- Membrane Compression
Remove the press tray from Section 1A and place the A-PRF™ clots within the compartment. Reposition the press tray to apply uniform compression. The calibrated weight of the tray is sufficient to form membranes. If thinner membranes or accelerated processing is desired, position the PRF piston 1D over the press tray to increase applied pressure.
- Exudate Collection
Compression will generate plasma exudate. Aspirate this exudate using a sterile syringe.
- Final Sticky Bone Formation
Transfer the collected exudate into Section 1B and incorporate it into the mixture of particulate graft and S-PRF™ plasma. Using a sterile instrument, blend thoroughly until a cohesive, moldable sticky bone consistency is achieved.
Once prepared, the sticky bone may be shaped to the desired dimensions and applied clinically for bone grafting procedures.
How to Produce A-PRF™ Membranes, Ponchos, and Plugs Using the PRF Ocean™
A-PRF™ Membrane Preparation
- Centrifuge the red tubes according to the established A-PRF™ protocol.
- Remove the red caps and allow the tubes to remain upright for approximately five minutes to complete coagulation. Tubes may be stored in Section 2A during this period.
- Remove each clot using sterile tweezers. Trim the red blood cell layer from the base of the clot with surgical scissors.
To form membranes, place the processed clots into Section 1A with the press tray removed. Reposition the press tray to apply uniform compression. The tray’s calibrated weight forms consistent membranes. If additional compression is required, position PRF piston 1D over the tray.
Following compression, membranes may be used immediately. If temporary storage is required, they may remain in Section 1A with the press tray removed. Pressed A-PRF™ membranes remain clinically usable for up to two hours after preparation.
A-PRF™ Poncho Fabrication
After membrane formation, position the membrane on top of the press tray in Section 1A. Using the integrated slit guide, create a central incision. This modification produces a poncho configuration suitable for placement around healing abutments or other prosthetic components.
A-PRF™ Plug Fabrication
After clot retrieval and removal of the red blood cell fraction, place each clot into one of the four cylindrical chambers in Section 1C. Position the PRF piston 1D over the selected chamber to apply vertical compression. Leave the clot in the plug cylinder with the piston pressing the clot for a minimum of five minutes to achieve proper plug formation.
