Example Embodiment
[0043] Example 1: The body porous section 3 and the threaded porous section 4 of the segmented porous implant occupies 3 fan-shaped areas each. The body porous section 3 is divided into two parts along the radial direction from the inner to the outer surface. The pore size gradient increases to 150μm and 350μm respectively. The pore size of the threaded porous section 4 is 60μm, and the thickness of the threaded porous section 4 is 0.3mm. The thickness of the porous section 3 is 0.5 mm, and the body roughness of the body 2 is 4 μm.
Example Embodiment
[0044] Example 2: The body porous section 3 and the threaded porous section 4 of the segmented porous implant each occupy 4 fan-shaped areas. The body porous section 3 is divided into three parts along the radial direction from the inner to the outer surface. The pore size gradient increases, respectively 150μm, 200μm and 250μm. The pore size of the threaded porous section 4 is 100μm, and the thickness of the threaded porous section 4 is 0.6mm. The thickness of the body porous section 3 is 1 mm, and the body roughness of the body 2 is 10 μm.
Example Embodiment
[0045] Example 3: The body porous section 3 and the threaded porous section 4 of the segmented porous implant each occupy 5 fan-shaped areas. The porous section 3 of the body is divided into three parts along the radial direction from the inner to the outer surface. The pore size gradient increases, respectively, 150μm, 200μm and 400μm. The pore size of the threaded porous section 4 is 140μm, and the thickness of the threaded porous section 4 is 0.9mm. The thickness of the body porous section 3 is 1.3 mm, and the body roughness of the body 2 is 20 μm.
