Zirconium oxide ceramic implant with three-dimensional communicated hierarchical pore structure and preparation method thereof
The invention relates to a zirconia ceramic implant with a three-dimensional communicated hierarchical pore structure and a preparation method, the zirconia ceramic implant comprises an implant body and an abutment, the abutment is arranged above the implant body through a retention prismatic table, the implant body sequentially comprises an implant root part, an implant body part and an implant neck part from bottom to top, a multi-stage hole structure is arranged in the implant body. The implant has the beneficial effects that the design that the bone combination holes are distributed in the surface of the implant body to be communicated with the internal hierarchical pore structure is adopted, the hierarchical pore structure promotes bone repair related cells to migrate and infiltrate inwards along pore channels, a good osteogenesis induction effect is achieved, human tissue and the implant device are promoted to be better combined in a short time, and the bone repair effect is improved. According to the invention, a certain tensioning effect is generated on the implant by the human tissue, the stability of the implant is improved, the high porosity required by the human tissue is ensured, meanwhile, the high mechanical property of the implant is ensured, and the rapid recovery of the oral cavity function is facilitated.
本发明涉及一种具有三维联通多级孔结构的氧化锆陶瓷种植体及制备方法，包括种植体本体和基台，基台通过固位棱台设于种植体本体上方，种植体本体从下到上依次包括种植体根部、种植体体部和种植体颈部，种植体本体内部设有多级孔结构。本发明的有益效果是：采用种植体本体表面分布骨结合孔连通内部多级孔结构的设计，多级孔结构促进了骨修复相关细胞沿孔道向内迁移和浸润，具有良好的诱导成骨作用，促使人体组织与种植体装置在短时间内更好地结合，使人体组织对种植体产生一定的拉紧作用，提高其稳固性，在保证满足人体组织所需的较高孔隙率的同时保证其有较高的力学性能，利于口腔功能的快速恢复。
