Embodiment 1

[0037] A three-dimensional model of the oral implant was established, and the three-dimensional model of the implant was sliced ​​with a thickness of 30 μm. After slicing was completed, the scanning path of the implant was planned, and the nine-square grid method was used for partition scanning. The area size was 2×2mm. When scanning different layers, the scanning direction was deflected by a certain angle, and the deflection angle was set to 37°.

[0038] The laser selective melting equipment adopts a combination of vacuuming and replacement. Firstly, the vacuum is pumped to 80KPa, and then high-purity Ar gas is filled into the forming chamber, and the replacement is repeated several times until the oxygen content in the forming chamber is lower than 100ppm and the pressure is maintained at 30mbar. .

[0039] Set the laser selection melting process parameters, the laser power for scanning the entity is 350W, the laser power for scanning the contour is 200W, the laser power fo...

Abstract

The invention discloses an oral implant 3D printing method. TTNZ alloy powder is prepared by a laser selective melting additive manufacturing process to form a TTNZ alloy oral implant, wherein the TTNZ alloy powder at least includes the following elements including, by mass, larger than 84% of Ti, 10%-10.9% of Ta, 1.45%-1.85% of Nb and 1.35%-1.85% of Zr. According to the oral implant 3D printing method, the novel TTNZ alloy powder is adopted as a raw material, and the laser selection melting additive manufacturing process is adopted, so that the prepared oral implant has good biosafety, synosteosis property and mechanical property. The invention also provides the oral implant prepared through the TTNZ powder and the method, and the good biosafety, synosteosis property and mechanical property are achieved.

Description

technical field [0001] The present invention relates to the technical field of medical implant materials, and more specifically, relates to a 3D printing method of an oral implant and an oral implant. Background technique [0002] At present, titanium alloys are mainly used as raw materials in the production of oral implants. Titanium alloys are usually divided into three types: α titanium alloys, β titanium alloys, and α+β titanium alloys. Alpha titanium alloys have good corrosion resistance, but lower strength. Although Ti-6Al-4V, a typical representative of α+β titanium alloy, has high strength and is easy to process, it is currently the main material for oral implants. It is not good, and contains cytotoxic elements V and Al, which can induce anemia, cancer and other diseases, which limits its clinical application to a certain extent. [0003] Therefore, it is an urgent problem to be solved in this field to provide an oral implant suitable for clinical application with...
