Porous ceramic skeleton, preparation method thereof and double-bionic resin ceramic composite material
The invention relates to the technical field of false teeth, and provides a porous ceramic skeleton, a preparation method thereof and a double-bionic resin ceramic composite material. The porous ceramic skeleton provided by the invention is of a three-dimensional structure formed by a plurality of unit cell structure arrays; each unit cell structure is a cube provided with a through hole, each through hole is of a chamfered three-cylinder structure, the sizes of three cylinders in the three-cylinder structure are the same, and the length of each cylinder in the three cylinders is the same as the side length of the cube. The porosity of the pore units is controlled by changing the parameter D, a porous ceramic framework with the porosity gradually changing from the bottom to the top is constructed, and the bionic effect of the resin permeable ceramic material and human teeth is achieved to the maximum extent from the physical property; the porous ceramic skeleton provided by the invention is high in porosity, pore diameter and pore distribution controllability, a three-dimensional through structure can be realized, and the bionic effect of a resin permeable ceramic material and human teeth is realized to the greatest extent from the structure.
本发明涉及义齿技术领域，提供了一种多孔陶瓷骨架及其制备方法以及一种双仿生树脂陶瓷复合材料。本发明提供的多孔陶瓷骨架为由若干个单胞结构阵列形成的立体结构；所述单胞结构为设置有通孔的正方体，所述通孔为倒角的三圆柱体结构，所述三圆柱体结构中的三个圆柱体尺寸相同，且所述三圆柱体中圆柱体的长度和所述正方体的边长相同。本发明通过改变参数D，控制孔单元的孔隙率，构建一种孔隙率从底部向顶部逐渐变化的多孔陶瓷骨架，从物理性能上最大程度的实现了树脂渗透陶瓷材料与人牙的仿生；本发明提供的多孔陶瓷骨架的孔隙率、孔径、孔分布可控性强，能够实现三维贯通结构，从结构上最大程度的实现了树脂渗透陶瓷材料与人牙的仿生。
