Problems solved by technology

[0006] However, we found in the process of practical application that although attaching inorganic materials to the surface of biological bone can effectively increase the mechanical properties of the material, the high-temperature composite operation will greatly remove the inorganic mineral components inside the biological bone itself and damage its mechanical properties. , to offset part of the mechanical properties brought by the active materials, so that the mechanical properties of the final composite inorganic material bio-bone scaffolds are only slightly higher than those of the untreated bone scaffolds, without significant improvement, which is far below the clinical requirements. Requirements for the use of supporting structures for bone tissue repair
[0007] In addition, although the above method can effectively increase the osteogenic activity of the material by compounding osteogenic active ingredients into biological bone, there is also a limitation in the compounding ratio of inorganic active materials, and it is impossible to flexibly control the compounding ratio of inorganic active materials to meet different needs. Application requirements and other issues

Abstract

The invention belongs to the technical field of biomaterials, and in particular relates to an artificial bone repair material with osteogenic activity, a preparation method and application thereof. The preparation method of the artificial bone repair material with osteogenic activity is to attach the bioactive material to the surface of the skeleton with a three-dimensional structure, and then quench; wherein, the bioactive material is in a molten state, and the skeleton is vibrated. complex. The present invention adopts the attachment method combining "molten form" and "vibration", which can make the bioactive material adhere to the surface of the basic skeleton better and evenly, and the degree of bonding is higher, and the surface structure is more regular, which can significantly improve the Comprehensive properties of artificial bone repair materials.

Description

Technical field [0001] The present invention belongs to the field of biomaterial technology, specifically relates to an artificial bone repair material having osteogenesis activity and mechanical support properties and preparation methods and applications thereof. Background [0002] The ideal artificial bone repair material should have the following characteristics: the primary role is structural support, which must have a certain mechanical strength and toughness; secondly, it should also have good biocompatibility, degradability and bone conductivity; in addition, it should have a suitable pore structure to facilitate cell proliferation and differentiation on its surface. [0003] Biologically derived bone has a natural three-dimensional spatial structure, which is conducive to promoting the growth and adhesion of bone cells, but its disadvantage is that the mechanical properties are poor, generally can only be used as a filling material and can not play a mechanical support p...
