Protocols

The available evidence shows PRF protocols vary significantly by clinical application and preparation method. However, specific dosing parameters and standardized protocols are limited in the current literature.

Preparation Methods

Multiple PRF variants are reported in studies, including:

Leukocyte-Platelet Rich Fibrin (L-PRF)
Advanced PRF (A-PRF+)
Injectable PRF (i-PRF)
Albumin PRF (Alb-PRF)
Horizontal PRF (H-PRF)

Clinical Applications

Periodontal Surgery:

Used as adjunct to open flap debridement for intrabony defects
Applied as membrane in combination with bone grafts
Protocols typically involve single intraoperative application

Oral Surgery:

Applied during immediate implant placement procedures
Used in sinus lift procedures as gel formulation
Single application at time of surgery appears standard

Temporomandibular Joint:

Intra-articular injection of injectable PRF (i-PRF) reported in case series
Specific injection volumes and frequencies not detailed in available abstracts

Wound healing:

Applied as dressing material for palatal wounds
Used in extraction socket healing protocols

Limitations

The current evidence lacks detailed standardized protocols regarding:

Specific blood volumes for preparation
Centrifugation parameters across different PRF types
Optimal timing and frequency of applications
Standardized concentration guidelines

Most studies report single applications during surgical procedures, but comprehensive dosing protocols are not well-established in the available literature.
