Embodiment 1

[0031] The 3D printing method of the present embodiment fast renewable cobalt chromium alloy coating tooth, it comprises the following steps:

[0032] (1) Obtaining denture size information: use a laser scanning device to scan the shape of the teeth occluded with the denture to obtain 3D data information on the surface topography of the denture, and then import it into the computer 3D software UG to continuously improve the 3D data information on the denture surface. Then convert the 3D model generated in the computer into an STL file and import it into the 3D printer control software.

[0033] (2) 3D printed denture main body: select zirconia powder mixed with a small amount of graphene and carbon nanotube powder, grind it with a ball mill until the particle size of the powder is less than 100um, fill it with protective gas and heat it up to 900°C, according to the imported 3D The main body of the denture is 3D printed by a 3D printer, and the laser is used for heat treatment...

Abstract

The invention discloses a method for 3D printing of a rapidly renewable cobalt-chromium alloy coated tooth. Laser scanning is adopted to assist manufacturing of an individual false tooth model, by using a 3D printing technique, zirconium dioxide powder is mixed with a small amount of graphene and carbon nanotube powder to make a false tooth main body, cobalt-chromium alloy powder is mixed with a small amount of the graphene and the carbon nanotube powder to make a false tooth base which is small and large gradually, and coating treatment is carried out on the false tooth base. The problems that a pure metal material is not attractive in appearance, a pure ceramic material is too crispy and long in recovery period after implanting can be overcome, people can feel that a false tooth and gingiva grow together, and an individual false tooth which is high in precision, good in wearing resistance, good in acid-alkali resistance, high in mechanical strength and good in biocompatibility can befinally manufactured.

Description

technical field [0001] The invention relates to the field of tooth preparation, in particular to a method for 3D printing fast and reproducible cobalt-chromium alloy-coated teeth to manufacture personalized dentures, which are applied to the restoration of tooth defects and restore tooth functions. Background technique [0002] 3D printing is based on digital model files, and uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. [0003] Zirconium dioxide is an excellent biomaterial, with good biocompatibility, superior to various metal alloys, including gold. Zirconium dioxide is non-irritating and non-allergic to the gums, and is very suitable for use in the oral cavity, avoiding adverse reactions such as allergies, irritation, and corrosion caused by metals in the oral cavity, and the thermal conductivity of zirconia is extremely low, and the weight is light, making it easier for patients to wear comfortable. [0004]...
