Study on Silk Fibroin-Reinforced Collagen-Based Composite Membrane for Periodontal Bone Tissue Regeneration

Based on the mechanism of intramembranous ossification of the alveolar bone, it is necessary to design a biomimetic membrane material based on the principle of GBR (Guided Bone Regeneration) to simulate the biological microenvironment of alveolar bone regeneration, promote the direct differentiation of stem cells into osteoblasts and rapid mineralization, thereby achieving the goal of alveolar bone regeneration. This section, based on bionic principles, proposes to enhance the mechanical properties of the collagen membrane with silk fibroin to achieve synergistic regeneration of periodontal bone/soft tissue. This project employs silk fibroin-reinforced collagen membrane technology to overcome the dual bottlenecks of insufficient strength and excessively rapid degradation of existing materials; establishes a "structure-guided, mechanically supported, factor-controlled release" trinity regeneration strategy to achieve precise repair of periodontal composite tissues. This study will provide new materials and methods for periodontal regeneration and offer a theoretical reference for the combined regeneration of other hard/soft tissues.
