Method for modifying calcium silicate biological ceramic through magnesium
The invention discloses a method for modifying calcium silicate biological ceramic through magnesium. The method is characterized by comprising the following steps: preparing biological ceramic powder; preparing 3D ceramic bio-ink; preparing a porous bracket by adopting a 3D ceramic ink writing device; carrying out sintering treatment on the obtained bracket; and expanding the sintered biological ceramic scaffold. Compared with the prior art, the method has the advantages that Ca in calcium silicate is partially replaced by Mg, key performance such as mechanical performance and biodegradability of the 3D printing biological ceramic scaffold is improved, and the 3D printing biological ceramic scaffold has bone regeneration potential and mechanical evolution advantages in the aspect of repairing parenchymal bone defects.
本发明公开了一种通过镁改性钙硅酸盐生物陶瓷的方法，其特征在于包括以下步骤：生物陶瓷粉末的制备；3D陶瓷生物墨水准备；采用3D陶瓷墨水书写装置制备多孔支架；将获得的支架进行烧结处理；将烧结后的生物陶瓷支架进行扩展。与背景技术相比，本发明的有益效果是：本发明以Mg部分取代硅酸钙中Ca的方法，实现了3D打印生物陶瓷支架机械性能和生物降解性等关键性能的改进，在修复薄壁骨缺损方面既具有骨再生潜力，又具有机械演化的优势。
