Evaluation of the Use of CGF Based Sticky Bone Packed in Fresh Odontectomy Site of Impacted Lower 3rd Molars
Sponsor: Cairo University
Summary
This clinical study aims to evaluate the effectiveness of Concentrated Growth Factor (CGF)-based sticky bone in enhancing bone healing after surgical removal of impacted mandibular third molars. Surgical extraction of impacted lower third molars is one of the most common procedures in oral and maxillofacial surgery and is often associated with postoperative complications such as pain, swelling, delayed healing, and bone defects within the extraction socket. CGF is an autologous platelet concentrate derived from the patient's venous blood through a specific centrifugation process. It contains a high concentration of growth factors that play a key role in angiogenesis, tissue regeneration, and bone formation. When combined with particulate bone graft material, CGF forms a cohesive structure known as "sticky bone," which can provide both biological stimulation and structural support for bone regeneration. In this study, CGF-based sticky bone will be placed into the fresh extraction socket immediately after surgical removal of the impacted mandibular third molar. Participants will be followed clinically and radiographically over a defined postoperative period. Clinical parameters such as pain intensity, soft tissue healing, and postoperative complications will be assessed, while radiographic analysis will be used to evaluate bone density and bone regeneration within the extraction site. The findings of this study may contribute to improving regenerative techniques in oral and maxillofacial surgery and provide evidence regarding the potential benefits of CGF-based sticky bone in enhancing postoperative healing and bone regeneration following third molar extraction.

Concentrated growth factors
This is a third-generation autologous blood concentrate prepared using a dedicated centrifugation system. The process creates a fibrin-rich organic matrix from the patient's own blood, CGF membrane is gently compressed using a sterile press to remove excess liquid. The compressed CGF membrane is mixed thoroughly with bovine xenograft bone particles.The mixture becomes cohesive and elastic, forming Sticky Bone, Then it is packed into the fresh extraction socket to enhance healing
