Abstract

The invention belongs to the technical field of biological ceramic materials and additive manufacturing, and particularly discloses a photocuring 3D printing ceramic composite material and a preparation method and application thereof. The light-cured 3D printing ceramic composite material is prepared from the following raw materials: basic ceramic powder, light-cured resin, an inorganic toughening agent and an auxiliary agent, the light-cured resin comprises first light-cured resin and second light-cured resin, the refractive index of the first light-cured resin is 1.42-1.52, and the refractive index of the second light-cured resin is 1.60-1.70; the volume ratio of the first light-cured resin to the second light-cured resin is (9: 1)-(2: 8). According to the preparation method disclosed by the invention, the biological ceramic, especially a fine complex pore structure with highly communicated interior, can be prepared through photocuring, the toughness of the biological ceramic implant for craniomaxillofacial is remarkably improved, the fracture toughness can reach 0.769-0.869 MPa.m < 1 / 2 >, and the bending strength is 6.18-7.84 MPa.

Description

technical field [0001] The invention belongs to the technical field of bioceramic materials and additive manufacturing, and in particular relates to a light-curing 3D printing ceramic composite material and a preparation method and application thereof. Background technique [0002] Bone defect is a common clinical disease, and its causes are often comminuted fractures caused by trauma and traffic accidents, or bone defects caused by surgical resection of tumors, as well as fractures and bone defects caused by various traumas and accidents. Among them, the repair of craniomaxillofacial bone defects has the highest requirements on implant materials. At present, the repair materials for craniomaxillofacial bone defects mainly include autologous bone, allogeneic bone, metal materials and bioceramic materials. Compared with bioceramic materials, other repair materials are more or less limited in their application in bone repair due to problems such as material selection, rejecti...
