Application research on repairing oral and maxillofacial epithelial defects with filin-protein porous composite scaffold. The silk fibroin solution was synthesized by hydrothermal synthesis, and the film was prepared by stirring and pouring. Then silk fibroin film and silk fibroin freeze-dried
support were prepared by stirring and smooth casting. It was characterized by FTIR, mechanical properties, dissolution detection, contact Angle and SEM. To evaluate the performance of this material in repairing rabbit oral mucosa and rabbit skin epithelial defects. The characterization shows
that the material has good contact Angle, mechanical properties, dissolution and biocompatibility. It has good repair function to rabbit oral epithelial tissue and skin epithelial tissue. Silk fibroin has excellent and unique properties. It has good development prospects and great clinical
value in tissue regeneration.
