Embodiment 1

[0022] The processing method of the invisible braces includes a step of processing the dental model, and the processing step of the dental model includes:

[0023] 1) Design the jaw model

[0024] Using three-dimensional graphics processing software to design the target dental model, the interior of the dental model is with an internal support structure;

[0025] 2) Rapid prototyping dental model with internal support structure

[0026] The 3D printing equipment is used to rapidly form the dental model with internal support structure.

[0027] Before the step of processing the dental model, it also includes obtaining the three-dimensional dental model data and rebuilding the three-dimensional digital model of the dental jaw. After the step of processing the dental model, it also sequentially includes molding the dental braces, cutting the corners of the dental braces, and grinding and polishing. braces.

[0028] The interior of the dental model is provided with an internal ...

Embodiment 2

[0052] Embodiment 2: Dental model test test

[0053] In this embodiment, the weight, yield rate and dental model parameters of the finished dental model are tested.

[0054] This test carries out weight test to three different types of jaw models, which are respectively solid model, hollow model and the model with internal support structure of the present invention, each processing 10, and detecting its weight, specifically refer to the following table 1.

[0055] Table 1 Weight comparison of different jaw models (unit: g)

[0056]

[0057] By comparing the weight of the solid model, the hollow model and the model of the present invention, as can be seen from Table 1, the weight of the model made by the present invention is the lightest, which reduces by 22.3% compared with the hollow model, and the weight of the hollow model is relative to the solid model Reduced by 18.9%, and the strength of the model made by the present invention meets the production requirements. This s...

Embodiment 3

[0064] Example 3: Acquisition of dental model with internal support structure

[0065] (1) Following the honeycomb shape of bees, the hexagonal grid structure is used as the reinforcement structure of the prototype of the dental model.

[0066] (2) The data size selected in the internal support structure involved in the present invention refers to the size of the jaw model: in the usual measurement data, in the direction of the horizontal section of the jaw model, the incisor part at the narrowest part of the gum is 7mm As mentioned above, the molar part is generally above 12mm, so the size of the inscribed circle of the hexagonal grid structure is selected to be below 5mm, and a sufficient test has been done on this size. See Table 3 for the test comparison table. On the basis of functional materials, the rules of shelling 1.6mm, mesh opening 5mm, and grid wall thickness 0.6mm are adopted for design and manufacture.

[0067] (3) The specific operation steps are as follows: ...

Abstract

The invention discloses a method for processing invisible braces, which includes a step of processing a dental model, the step of processing a dental model includes: (1) designing a dental model, using three-dimensional graphics processing software to design a target dental model, and the tooth The interior of the jaw model is with an internal support structure; (2) Rapidly forming a dental model with an internal support structure, using 3D printing equipment to rapidly form the dental model with an internal support structure. The processing method of the invisible braces of the present invention improves the processing technology of the invisible braces, and substitutes the support structure inside the jaw model, which saves a large amount of raw materials for printing and reduces the production cost; The processing accuracy is improved, the time required for the entire braces production process is shortened, and the processing efficiency is improved; the weight of the honeycomb tooth and jaw model involved in the present invention is greatly reduced, which is beneficial to saving transportation costs in the production process.

Description

【Technical field】 [0001] The invention relates to the technical field of dental processing, more specifically, to a processing method for invisible braces. 【Background technique】 [0002] With the development of orthodontics, the invisible orthodontic technology applied to the correction of malocclusion is gradually becoming mature in mainland China. In recent years, 3D printing technology has set off a wave of industrialization and has gradually penetrated into various fields of the manufacturing industry. Naturally, 3D printing technology has also begun to be applied to invisible orthodontic technology to assist in the production of personalized polymer plastic invisible braces. [0003] At present, the rapid prototyping of dental models using 3D printing technology has become more and more accepted by dental material and equipment manufacturers because of its high precision. However, the high cost of 3D printing technology, especially the high price of raw materials for...
