Problems solved by technology

The disadvantage of this is that the extra base part will take up a considerable part of the time when 3D printing is used, which prolongs the production time of the tooth model and virtually prolongs the production cycle of a single appliance
At the same time, the extra base part is a waste of 3D printing consumables, resulting

Embodiment 1

[0029] Such as Figure 1-3 The tooth model shown includes the crown part 1 of the upper part and the gingival part 3 of the lower part, and the truncated cone sheet 2 is arranged below the gingival part 3, and the upper bottom surface area of ​​the truncated pyramid sheet 2 is smaller than the lower bottom surface area, and The diameter is greater than the width of the gingival part 3, and the bottom surface is flush with the bottom surface of the gingival part, such as image 3 shown.

[0030] Such as Figure 4 As shown, the truncated cone sheet 2 is a truncated cone, the height of the truncated cone sheet 2 is 1.5mm, the base angle is 40°, and the upper bottom surface area is about 153.86mm 2 , the bottom surface area is about 314mm 2 . The frustum piece 2 is located in the middle of the dental arch. When the diaphragm is separated from the tooth model, the two symmetrical parts in the middle of the dental arch bear basically the same force, which is conducive to separa...

Embodiment 2

[0035] Such as Figure 6 As shown, the frustum sheet 2 is a truncated polyhedron, the height of the frustum sheet 2 is 1.8mm, the base angle is 50°, and the upper bottom surface area is about 145.32mm 2 , the bottom surface area is about 330mm 2 .

[0036] All the other are with embodiment 1.

[0037]When the above tooth model was produced, the base was not printed, and only the crown 1, the gingiva 3 and the frustum 2 were printed, which saved 26% of the printing time compared to printing the 8mm thick base. At the same time, the consumption of expensive printing consumables is also saved, and the production cost of each appliance can be reduced by 20% to 30%.

Abstract

The invention relates to a teeth model. The teeth model comprises an upper dental crown part and a lower gingival part, wherein a truncated cone sheet is arranged below the gingival part, the upper bottom area of the truncated cone sheet is smaller than the lower bottom area, the diameter of the upper bottom is greater than the width of the gingival part, and the lower bottom is leveled to the bottom of the gingival part. A method for preparing a concealed correcting device by utilizing the teeth model comprises the following steps: (1) obtaining the teeth model with the truncated cone sheet on the bottom by virtue of three-dimensional modeling and three-dimensional printing; (2) placing the teeth model on a metal plate of a film pressing machine, and carrying out the film pressing; (3) after the film pressing is ended, separating a diaphragm from the teeth model, slightly bending the hot-pressed diaphragm part, enabling the truncated cone sheet to be warped, holding, by a hand, the truncated cone sheet, and vigorously turning upwards the diaphragm, thus obtaining a primary tooth socket template; and (4) further processing to obtain the concealed correcting device. The method is simple and practical, the operation speed is high, the efficiency is improved, the cost is reduced, and the damage probability of the macromolecular diaphragm when in demolding can also be maximally reduced.

Description

technical field [0001] The invention belongs to the field of orthodontics, and in particular relates to a tooth model for preparing an invisible aligner and a method for preparing an invisible aligner using the tooth model. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to dental health and beauty. Bracket-free invisible orthodontic technology is rapidly emerging and developing, and product manufacturers need to provide solutions and suppress invisible aligners suitable for each different stage, so the demand for clear aligners is also increasing. The existing invisible aligner laminating technology is to embed the base of the three-dimensionally printed tooth model in the steel sand of the laminating machine, and then carry out hot pressing and laminating. The 3D printed tooth model has a base about 10 to 20 mm thick. In order to maintain the stability of the tooth model when laminating the film and avoid...
