Problems solved by technology

[0004] The denture model is obtained by scanning the three-dimensional shape data of the teeth and the whole dentition and then remodeling. It can scan the isolated teeth or the in-body teeth (the teeth that are still in the human body) and mold them, but it cannot be used in the case of patients with missing teeth. Scanning and building denture models

Embodiment

[0026] Example: figure 1 It is a 3D printing device disclosed in the present invention, which includes a computer control system 1 and a molding chamber 4. The computer control system 1 is connected to a fiber laser 2, and the top of the molding chamber 4 is connected to a beam isolator 3. One end of the beam isolator 3 faces the laser light emitted by the fiber laser 2 , and an F-Theta lens 10 is provided at the connection between the other end of the beam isolator 3 and the molding chamber 4 . The beam isolator 3 is L-shaped, and the vibrating mirror 9 and the beam expander 8 are fixed inside the beam isolator 3 , wherein the vibrating mirror 9 is located at a corner of the beam isolator 3 . The laser light passes through the beam expander 8 first, then is refracted by the vibrating mirror 9 , then passes through the F-Theta lens 10 , and finally enters the molding chamber 4 .

[0027] Such as figure 1 As shown, the bottom of the molding chamber 4 is provided with a moldin...

Abstract

The present invention relates to the technical field of 3D printing and particularly relates to a false tooth 3D printing manufacturing technology and a 3D printing device thereof. CBCT is used for shooting a plurality of horizontal tomograms of teeth of a patient and a tomogram distance between the two horizontal tomograms shot before and late is less than 0.5 mm; a symmetry axis of a whole dentition in each horizontal tomogram is drawn; positions symmetrical to missing teeth on the horizontal tomograms are found out and marked, the horizontal tomograms are uploaded to AutoCAD, outlines of the teeth closest to the marks in the whole dentition in the AutoCAD are drawn out, and mirror images of the outlines are stored as electronic documents; and all the electronic documents of the horizontal tomograms are uploaded to a computer of the 3D printing device in sequence. The false tooth 3D printing manufacturing technology has a characteristic that a missing tooth false tooth model can be established under a condition that the teeth of the patient are missing.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a denture 3D printing manufacturing process and a 3D printing device thereof. Background technique [0002] Dentures are what people often call "false teeth". In medicine, it is a general term for restorations made after the upper and lower teeth are partially or completely missing. The denture processing industry is a high-precision industry. The existing denture processing methods all use wax casting as the main production process. The auxiliary process is complicated and there are many auxiliary materials. Most of them are produced manually, with a low degree of automation and low production efficiency. [0003] The patent with the authorized notification number CN208929212U discloses a denture metal laser 3D printing device. When in use, the denture model file is transmitted to the control box through the USB socket. Under the joint action of adjusting the motor, 3D prin...
