Abstract

A transparent correction teeth brace comprises an outer surface (1), an inner surface (2) and a thickness formed between the inner surface and the outer surface, wherein the thickness is unevenly distributed at different positions of the teeth brace, and the stressed, reinforced, wear-resistant and/or attachment-added positions of the teeth brace have a thickness greater than the positions that are normally stressed, less stressed, unstressed and/or serving only as connection. The transparent teeth brace has diverse functions due to the different thickness or rigidity of the transparent teeth brace itsself and the additional components and/or accessories on the teeth brace, and is not prone to deformation and material failure.

Description

Transparent orthodontic braces

Technical field

The present invention relates to the field of transparent braces, and more specifically, to a transparent orthodontic braces and a computer-aided manufacturing method thereof.

Background technique

The existing transparent braces are braces with uniform thickness or rigidity. In the process of correcting teeth, it is generally necessary to use multiple different transparent braces to gradually correct the position of the patient's teeth. Each transparent braces can correct the movement range of the teeth within 0.25~0.3 However, this range is not the limit range of the physiological movement of the teeth. The factors that limit this range are the material of the transparent braces and the way of treatment through the transparent braces. Due to the limited elasticity of transparent braces, the material will be strained or deformed during the treatment. Therefore, even if transparent braces with different softness and hardness are used in different stages of treatment, they may not be able to give the teeth enough correction strength, because transparent braces are uniform The thickness or rigidity of the braces is too single in the correction.

Summary of the invention

The present invention aims to overcome at least one of the above-mentioned defects of the prior art, and provides a transparent correction and a computer-aided manufacturing method thereof, which is used to solve the problem of insufficient correction strength of the existing transparent braces, prone to strain and deformation, and too single function The problem.

After passing through the S4 step, a part of the transparent braces where it needs to be stressed, strengthened, wear-resistant, and/or additional accessories, will appear rigid or thicker than braces that are generally stressed, less stressed, less stressed and/ Or the rigidity or thickness of the connecting position is greater, because the role of this part of the brace in the position that needs to be stressed, strengthened, wear-resistant and/or additional accessories is that the correction needs more than the general force correction. Tooth, and/or increase the strength and/or wear resistance of this part to make the braces less prone to material strain and deformation, and/or add accessories to correct the teeth in different ways, and they are under normal stress , The position of less force, no force, and/or only the connection function plays the role of connecting other parts of the brace, and/or for the correction requires general force correction, less force correction and/ Or teeth that do not require force correction, so the rigidity or thickness of this part of the braces is unevenly distributed, which is conducive to the realization of different functions of the braces in different positions and more diversified functions.

Further, in the transparent braces, another part of the transparent braces includes an outer surface, an inner surface, and a rigidity or thickness formed between the inner and outer surfaces, and the rigidity or thickness is uniformly distributed at different positions of the braces, The other part of the transparent braces further includes a reinforcing component, which is arranged at the position where the braces are subjected to force, reinforcement, wear resistance, and/or additional accessories.

Because this other part of the transparent braces plays a role in the position that needs to be stressed, strengthened, wear-resistant and/or additional accessories is to be used to correct the teeth that require more than normal force correction, and/or increase the strength of the force and/or the part Or the degree of abrasion resistance makes the braces less prone to material strain and deformation, and/or additional accessories can be added to correct the teeth in different ways, and they are generally stressed, less stressed, not stressed and/or only lifted. The role of the connection position is to connect other parts of the braces, and/or to correct teeth that require general force correction, less force correction, and/or no force correction, so in the S4 Steps: When designing this other part of the transparent brace, it is necessary to install a reinforcing member at the position of the force, reinforcement, wear resistance and/or additional accessories, which makes the part of the brace more rigid or thicker than other positions where no reinforcing member is provided , It is helpful for the braces to achieve different functions in different positions, and the functions are more diversified.

Compared with the prior art, the present invention has the following beneficial effects: through the different thickness or rigidity of the transparent braces and the additional components and/or accessories on the braces, the functions of the transparent braces are more diversified, and at the same time, it is not prone to deformation and material. Strain situation.
