Abstract

The present invention relates to a bone repair material composition comprising a bone cement component and nano silicon nitride, wherein the bone cement component comprises magnesium oxide and sodiumdihydrogen phosphate, and the weight ratio of the nano silicon nitride to the bone cement component is 1: (1.5-9). The bone repair material prepared according to the invention has dual effects of resisting infection and promoting bone growth, not only inhibits bacterial adhesion, but also promotes adhesion and proliferation of osteoblasts, and can play a role in resisting infection and improving bony combination between an implant and a host bone after being implanted into a body.

Description

technical field

[0001] The invention relates to the field of medical biomaterials, in particular to a bone repair material and its preparation method and application. Background technique

[0002] Bone is a natural inorganic / organic composite material, more than 90% of the organic phase is collagen, and the inorganic phase mainly includes calcium phosphate, hydroxyapatite (HA), sodium phosphate, calcium citrate, magnesium phosphate etc., among which hydroxyapatite is the main one. When the natural bone is traumatized, due to the joint action of bone morphogenic protein and growth factors, it has a certain self-repair ability. After the bone repair material is implanted, it can ensure that the patient's bone defect remains fixed and the patient can carry out normal work. Daily activities, and often bone repair materials can also help damaged bone tissue repair itself, speeding up the healing process.

[0003] The development of bone repair materials has experienced numerous...
