NOVELTY - The bracket has a porous bracket main body made of raw material comprising calcium magnesium silicate, graphene oxide and silk fibroin, where mass ratio of calcium-magnesium silicate, graphene oxide and silk fibroin is measured as (0.001 ~ 50): (0.001 ~ 50): 100, porosity of the porous bracket main bracket is measured as 80 % to 99 %. and aperture of the porous bracket main body is measured as 0.001 mu m to 300 mu m. USE - Porous bracket. ADVANTAGE - The porous bracket has better mechanical property, water absorption rate and water retention rate, and can slowly release calcium, magnesium and silicon ion, and has better mineralization, so as to promote hemostasis, osteogenic differentiation, vascularization and inhibiting osteoclasia differentiation. The bracket avoids drug release and short active factor action time by realizing purpose of effectively and continuously promoting bone repair. The bracket is simple in structure, and reduces preparation time consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a porous bracket manufacturing method.
