THBC/CGF for Alveolar Bone Regeneration: A Real-World Study
A Real-World Study on Temperature-Sensitive Hydroxybutyl Chitosan-Loaded Concentrated Growth Factor for Alveolar Bone Defect Repair
Stomatological Hospital Affiliated with Fujian Medical University
136 participants
Aug 1, 2024
INTERVENTIONAL
Conditions
Summary
This study aims to combine real-world research with relevant bone repair materials and techniques to improve alveolar bone resorption in extraction sockets following impacted wisdom tooth removal, while achieving effective bone preservation or promoting bone regeneration. All eligible cases within specified parameters will be included in the clinical study scope. Based on real-world clinical data, we will proactively collect postoperative clinical examination findings and imaging data. Statistical analysis will be performed on clinical outcomes and follow-up data from patients undergoing mandibular impacted M3 extraction. The study aims to clarify the therapeutic efficacy of the thermosensitive hydroxyethylchitosan-loaded concentrated growth factor group in repairing mesial bone defects of M2s following M3 extraction.

Interventions
* THBC Component: Its key component is hydroxybutyl chitosan. The product is supplied as a clear or light yellow, easily flowing liquid at storage temperature (2-8 degrees Celsius) and undergoes a sol-gel transition to form a transparent or semi-transparent gel at body temperature (37 +/- 2 degrees Celsius). The product is composed of hydroxybutyl chitosan, glycerol, and purified water. It is designed to provide a physical barrier, create a moist wound-healing environment, and alleviate pain. * CGF Component: Concentrated Growth Factor (CGF) is a third-generation autologous platelet concentrate obtained from the patient's own venous blood through a specific centrifugation process. It presents as a dense, three-dimensional fibrin matrix rich in platelets, leukocytes, cytokines, and growth factors (such as PDGF, TGF-beta, VEGF). * Composite Process: Mixed under sterile conditions, injection flow rate less than or equal to 0.5 mL/s.

After tooth extraction, gently scraping the bone wall induces bleeding, allowing a natural blood clot to form. Within 30 minutes postoperatively, ensure the clot fills more than 90 percent of the socket without applying experimental biomaterials.
