Problems solved by technology

In the field of invisible orthodontics, the use of braces for orthodontic treatment is more and more selected and accepted by patients, but the invisible braces used in the prior art are all single-layer, and the thickness of the diaphragm is about 0.6-0.75mm, and the selectivity is small. For patients with periodontal disease or patients with attachments, it is difficult to remove the belt, and the thicker the braces are, the stronger the foreign body sensation will be and the comfort will be reduced.

Embodiment １

[0038] Embodiment 1 A kind of preparation method of multi-layer braces

[0039] A kind of preparation method of double-layer braces, total thickness is 1.0mm, and it is carried out according to the following sequence of steps:

[0040] (1) Production of 3D dental model

[0041] Print the collected dental model data on the 3D printer, and then clean and solidify the dental model;

[0042] (2) Modification of dental model

[0043] The discontinuous gap between the teeth in the jaw model is trimmed; wherein, the trimming method is artificial filling or software design filling, and the artificial filling method is artificial filling of dental wax or filling of dental plaster; software design filling is carried out Edit and fill the jaw model data before 3D printing;

[0044] (3) Compression of inner braces

[0045] A) To identify the diaphragm, the identification method is to scan and identify on the laminating machine;

[0046] B) Use a diaphragm with a thickness of 0.5mm fo...

Abstract

The invention discloses a preparation method of multilayer braces. The multilayer braces are not less than 2 layers, and the total thicknesses of the multilayer braces are 0.2 to 1.2mm. The preparation method is implemented according to the following sequence of steps: (1) manufacturing a three-dimensional (3D) dental model; (2) trimming the dental model; (3) pressing inner-layer braces; (4) pressing sub-layer braces; (5) pressing N-layer braces, and finally preparing the multilayer braces. With the adoption of the multi-layer pressing method, technical parameters in the pressing process are controlled, and the personalized multilayer braces are finally manufactured. The preparation method of the multilayer braces disclosed by the invention is suitable for preparation of the multilayer braces.

Description

technical field [0001] The invention belongs to the field of orthodontic treatment, and relates to a preparation method of a dental brace, in particular to a preparation method of a multilayer dental brace. Background technique [0002] Traditional orthodontic treatment is mainly to set brackets and arch wires on the surface of the tooth list to play a role in orthodontic treatment, and to perform orthodontic treatment by twisting and pushing. For the sake of aesthetics, the braces are transferred from the lip side to the lingual side, which cannot be seen from the outside. However, this method has higher requirements on the doctor, and the patient has a larger stew in the mouth, which not only enhances the foreign body sensation, but also costs more. With the advancement of technology, invisible orthodontics are more and more accepted and used by patients. Invisible orthodontics without brackets is a computer-aided design and production of transparent elastic material movab...
