  • Method for preparing a functionally gradient material for guided periodontal hard and soft tissue regeneration
    Patent number: 11696974
    Abstract: A functionally gradient material for guided periodontal hard and soft tissue regeneration includes a 3D printed scaffold layer and an electrospun fibrous membrane layer. The content of hydroxyapatite in the 3D printed scaffold layer is higher than the content of hydroxyapatite in the electrospun fibrous membrane layer. The pore size of the 3D printed scaffold layer is larger than the pore size of the electrospun fibrous membrane layer. The pore size of the 3D printed scaffold layer is 100-1000 ?m, and the fiber diameter of the electrospun fibrous membrane layer is 300-5000 nm. The electrospun fibrous membrane layer is in a random distribution or an oriented arrangement or has a mesh structure. The thickness of the electrospun fibrous membrane layer is 0.08-1 mm.
