[0011] Example Metal artificial trabecular bone for bone graft fusion and repair between vertebral bodies
[0012] According to the structure and shape characteristics of vertebral interbody bone defects, the metal artificial bone trabecula between vertebral bodies was prepared. The beam information is input into the computer-controlled electron beam melting molding equipment, and the temperature of 1800 °C generated by the electron beam is used to scan the titanium alloy powder in the molding equipment layer by layer and melt at high temperature until it accumulates into the required hexahedron shape. It has the shape, strength and elastic modulus similar to that of biological cancellous bone, and its surface has a porous structure to form a rough and loose outer surface, with an average pore diameter of 500 microns and a porosity of 60%.
[0013] According to the preparation method of the embodiment, according to the needs of the bone defect site, CT scan reconstruction is p...
