Porous titanium sheet which can be filled with composites in biological experiment and preparation method thereof

Abstract

The invention discloses a porous titanium sheet which can be filled with composites in a biological experiment and a preparation method thereof. The porous titanium sheet is of a cylindrical structure, wherein a first porous structure is arranged on the porous titanium sheet, and includes a plurality of vertical pores penetrating from one end face of the porous titanium sheet to the inside of theporous titanium sheet, the porous titanium sheet is provided with a second porous structure, and the second porous structure includes a plurality of filling through pores penetrating through the sidewalls of the porous titanium sheet, the filling through pores being parallel to the end face of the porous titanium sheet. As the porous titanium sheet is provided with filling through holes in the porous titanium sheet, the porous titanium sheet can be filled with different dosages and different materials in the filling through holes, and therefore, the porous titanium sheet can carry out multiple types of implant biological experiments. 3D printing rapid prototyping of the porous titanium sheet in the invention improves the preparation speed and the processing accuracy of the porous titaniumsheet. The invention is used in biological experiments of cells, animals and the like of orthopedic implants or dental implants.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a porous titanium sheet used for biological experiments on cells, animals, and the like for orthopedic implants or dental implant materials, structures, and surface morphology. Background technique [0002] At present, in the fields of dentistry and orthopedics, composite implants composed of granular fillers or reinforcing fibers and metals have gained popularity. However, the implants currently used in biological experiments of implants generally use pure porous titanium sheets. The use of pure porous titanium sheets for experiments can effectively simplify the process and reduce the production cost of experimental samples. However, pure porous titanium sheets have a solid structure and only Surface treatment is possible, so pure porous titanium sheets can only simulate the surface of implants by surface treatment. To carry out bio-implantation experiments ...

However, the implants currently used in biological experiments of implants generally use pure porous titanium sheets. The use of pure porous titanium sheets for experiments can effectively simplify the process and reduce the production cost of experimental samples. However, pure porous titanium sheets have a solid structure and only Surface treatment is possible, so pure porous titanium sheets can only simulate the surface of implants by surface treatment

To carry out bio-implantation experiments of composite implants composed of granular fillers or reinforcing fibers and metals requires a large number of implant sample preparations, which will greatly increase the cost and time of experiments.
