Abstract

The invention relates to human bone defect filling original position self-solidified bioactive material and the preparation method thereof. The material is bone / tooth defect repair material which is developed with bioactive calcium phosphate / tricalcium silicate composite powder and mixing liquid having the biological activity as raw materials. Compared with the prior material, the material of theinvention has the advantages that the biological activity is excellent, the shaping is arbitrary, the material is self-solidified, no cytotoxicity exists, and the degradation is gradual, the degradation rate can be adjusted, and the effect of inducing bone-like apatite formation can be achieved; the biological activity is more excellent than that of the calcium phosphate calcium phosphate bone-like cement, and the preparation method is simple.

Description

technical field

[0001] The invention relates to a bioactive calcium phosphate / tricalcium silicate composite self-curing material, a preparation method and an application. The provided material is used as a filling and repairing material for human hard tissue defects, that is, as a bioactive material for filling and repairing human bone and tooth defects. , for use in orthopedics, dentistry and minimally invasive treatments. It belongs to the field of medical biomaterials. Background technique

[0002] In the mid-1980s, Brown and Chow invented a new type of self-curing bioactive bone repair material - calcium phosphate cement (Calcium Phosphate Cement; CPC). CPC refers to a calcium phosphate (Calcium Phosphate, CP) material that is mixed with several phosphate powders and a blending solution, undergoes a hydration reaction at room temperature or the temperature of the human body, and can spontaneously solidify. CPC is different from ceramic materials. Its preparation, moldi...
