Description
Technical Field
[0001] The present invention relates to the technical field of medical equipment, and in particular to a denture manufacturing method based on 3D printing. Background Art
[0002] The denture processing industry is a high-precision industry. The existing denture processing methods all use wax casting as the main production process, with many auxiliary processes and materials. The working environment of technicians is poor, with a lot of dust and odorous gases. 3D printing devices can print out dentures. Their advantages are fast production time, medical grade, no odor, and the printed dentures are very transparent and natural, very close to real teeth in appearance and texture.
[0003] In the existing technical scheme, a method for manufacturing dentures based on 3D printing is proposed with publication number: CN105030357B, which includes the following methods: after the teeth are occluded with a first occlusal material, a first occlusal model is formed; the structure of the first occlusal model is scanned by a scanning device, and the height, width and thickness of the scanned denture are adjusted; a first 3D denture image is formed in a three-dimensional design software; and the denture is produced in a 3D printing device according to the first 3D denture image.
[0004] In order to solve the problem that although the denture image formed in the 3D software is accurate, if the denture is only made according to the scanned size without proper correction, there may be deviation in the denture. Teeth require high precision. If the size of the teeth is too large, it may easily cause discomfort in the mouth. Contact with the teeth on both sides may cause deformation of the teeth on both sides, and even cause the teeth to fail to be installed. If the size of the teeth is too small, it may easily cause air leakage from the teeth and affect pronunciation. The existing technology is to adjust the size of the denture image generated after scanning, so that the denture is easy to install, prevent the denture from colliding with the teeth on both sides, and the denture and the grinding teeth, improve the accuracy of the denture, and make it more comfortable for people to handle it after installing the denture.
