Problems solved by technology

[0003] The advantages of plastic braces orthodontics are: beautiful, removable, hygienic, quantitative, and can improve the work efficiency of orthodontists; but there are still some improvements in the technology and production process of orthodontic braces currently used in Europe and the United States Space, such as manufacturing methods, product accuracy, production costs, measuring instruments and quality inspection methods, etc.

Embodiment Construction

[0028] 1Precisely copy the tooth model and perform segmentation and restoration of the jaw.

[0029] Precise reproduction of teeth using precision molding materials. There are many options for molding materials, such as: gypsum, super-anhydrite, plastic, resin, metal, etc. The selected materials must have physical properties such as high precision, high strength, high temperature resistance, and wear resistance. Take super anhydrite or precision resin as an example: inject a mixture of super anhydrite and water with a water-powder ratio of 22:100, or a resin mixture with a curing agent and resin ratio of 1:7, into the tooth impression, oscillate fully, and discharge air bubbles. After curing, take it out and cut it into individual tooth models. According to the plaster model or other aids, the divided model teeth are rearranged and restored to their original shape.

[0030] In order to adjust the position of model teeth more accurately and use computer-aided design of treatm...

Abstract

The invention relates to a manufacturing method of a polymer orthodontic bracket, which has high precision, low production cost, convenient usage and can be removed during the using process. The manufacturing method comprises the following operation steps: (1) a dental model is precisely duplicated and carried out the segmentation; (2) the dental model after the segmentation is reduced and arranged on a fixed object; (3) the precise adjustment of the position and the angle of a tooth after the segmentation is realized by using the automatic or manual method via the change of the physical state or the shape of the fixed object of the dental model; (4) the quality detection and the control of a closed loop are implemented by comparing the pre-adjusted position and the angle with the actual measurement position and the angle of the tooth; (5) the film pressing is carried out on the dental model after checking the angle and the position.

Description

1. Technical field: [0001] The invention relates to a manufacturing method of orthodontic braces, in particular to a manufacturing method of polymer orthodontic braces. 2. Background technology: [0002] The traditional orthodontic method uses devices such as brackets and arched wires, which are large in size and have a strong foreign body sensation, making it uncomfortable for patients to wear; the color contrast with the teeth is large and not beautiful; they cannot be removed during the entire treatment period, and tartar is likely to occur and damage the teeth. Enamel, with many edges and corners, is easy to accumulate foreign matter on the surface of the teeth, and it is not convenient for oral cleaning, which is not conducive to oral hygiene. In recent years, with the widespread application of computer technology and new manufacturing processes in the orthodontic field, plastic braces orthodontics have begun to be accepted by the orthodontic field and patients in the U...
