    摘要: An intervertebral fusion device includes a structural ceramic body. The structural ceramic body has a bottom surface, a top surface, a peripheral surface connected between the bottom surface and the top surface, and at least one pore channel penetrating the bottom surface and the top surface. The inner surface of the pore channel is either a convex curved surface or a funnel-shaped surface. For the pore channel having the convex curved surface, the pore diameter of the pore channel gradually expands from the center of the pore channel to the top surface and the bottom surface. The pore diameter can also gradually expand from the bottom surface to the top surface. The peripheral surface of the structural ceramic body is wavy or zigzag.

    摘要: An efficient biphasic calcium phosphate coating method. A high-concentration (4.5×) supersaturated calcium phosphate solution (SCPS) is used for coating and a thicker continuous coating is formed on a titanium disc. The coating contains dicalcium phosphate dihydrate and hydroxyapatite. The coating has improved encapsulation efficiency of a protein FITC-BSA and releases less Ca2+ under an acidic condition. A more efficient coating with a high yield and a protein encapsulation efficiency can be obtained with a less SCPS solution volume and a shorter coating time, such that a cost is greatly reduced in clinical application and the coating is very expected to be used in an osteogenic implant material in the biomedical field.
