3D printing manufacturing method of pure titanium dental crown

Abstract

A 3D printing manufacturing method of a pure titanium dental crown comprises the five steps of mold taking and modeling, 3D cutting, 3D mold drilling, surface treatment and gluing, and manufacturing of the pure titanium dental crown is completed. The dental crown is made of a pure titanium material, and the mechanical property and plasticity of titanium are utilized, so that the service life of the dental crown is prolonged, and the comfort of a patient in daily use of the dental crown is improved. The method is different from 3D printing in a layer-by-layer stacking form of additive manufacturing in the prior art, a three-axis displacement system of 3D printing is utilized, firstly, a pure titanium material is subjected to 3D cutting and polishing, so that the external structure of the material meets the use requirement of the oral cavity of a patient, then, the polished material is subjected to 3D mold drilling, and an internal recess required by dental crown installation is machined; and the 3D scanning technology and the 3D modeling technology are utilized in the cutting, polishing and mold drilling processes, the dental crown manufacturing precision and manufacturing efficiency are improved, and the defects that in the prior art, dental crown manufacturing time is long, manufacturing precision is low, and the service life is short are overcome.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing manufacturing method of a pure titanium crown. Background technique [0002] Teeth are the hardest organs in the human body. In addition to the functions of cutting and chewing, they also play the role of maintaining facial shape and assisting pronunciation. Dental crowns, also known as braces, are a method for repairing teeth. When the teeth are damaged and When it is difficult to restore by filling, artificial crowns can be made of different materials and placed on the reduced natural teeth. [0003] The existing dental crowns are generally made of materials with high hardness such as ceramics, which are beautiful in appearance but poor in toughness and stability, and are prone to damage during use, with low elongation and reduction of area and long production and processing time; The current 3D printing technology generally adopts the method of additive manu...

Problems solved by technology

[0005] In order to solve the technical problems existing in the background technology, the present invention proposes a 3D printing manufacturing method of a pure titanium crown, which uses pure titanium material to make the crown, and utilizes the mechanical properties and plasticity of titanium to improve the service life of the crown and the patient's daily life. Comfort when using dental crowns; this method is different from the 3D printing in the form of additive manufacturing layer by layer in the prior art. Using the three-axis displacement system of 3D printing, the pure titanium material is firstly 3D cut and polished to make the external structure of the material In line with the needs of the patient's oral cavity, 3D drilling templates are used to process the polished material to process the internal depression required for crown installation; the cutting, grinding and drilling template processes use 3D scanning technology and 3D modeling technology to improve The precision and production efficiency of crown production overcome the defects of long crown production time, low production precision and short service life in the prior art
