THBC/CGF for Alveolar Bone Regeneration: A Real-World Study

RecruitingNA

Sponsor: Stomatological Hospital Affiliated with Fujian Medical University

Conditions: Alveolar Bone Loss, Alveolar Ridge Resorption After Extraction, Tooth, Impacted

Interventions: Temperature-sensitive hydroxybutyl chitosan-loaded concentrated growth factor, Temperature-sensitive hydroxybutyl chitosan, Autologous Concentrated Growth Factor, Natural Healing without Biomaterial Intervention

Countries: China

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.
