Guided Bone Regeneration: CGF and PRF Combined With Various Types of Scaffolds-A Systematic Review.

Objective: Bone regeneration plays a pivotal role in modern oral surgery, particularly in facilitating successful implant-prosthetic rehabilitation. This systematic review explores the regenerative potential of growth factors, such as platelet-rich fibrin (PRF) and concentrated growth factors (CGFs), when combined with various types of scaffolds in bone augmentation procedures, including guided bone regeneration, split crest, sinus lift (SL), and alveolar ridge preservation. Method: A comprehensive search strategy yielded 18 relevant studies, which were analyzed for bone formation and stabilization outcomes. Results: Results indicate that PRF enhances bone regeneration and stabilization in SL and ridge augmentation procedures, while CGFs facilitate surgical techniques and augment bone. However, some studies did not report significant differences. Growth factors also demonstrate benefits in wound healing, reducing bone resorption, and enhancing socket preservation. Conclusion: Despite valuable insights, further research is needed to comprehensively understand the characteristics of growth factors in various surgical interventions, ensuring informed decision-making in bone regeneration surgery.
