In order to fully understand the objects, features and advantages of the present invention, the present invention will be described in detail by the following specific embodiments and the accompanying drawings.

Please refer to FIG. 1 , which is a flow chart of a method for manufacturing an invisible braces according to the present invention. The manufacturing method comprises seven steps. Hereinafter, the production method will be described with reference to Fig. 1, Fig. 2a to Fig. 2e, and text.

First, as shown in FIG. 1, in step S101, a tooth data of a user is collected, and a photo of the mouth of the user, a scan file, a bite record, and the like are usually collected.

Next, as shown in FIG. 1 , in step S103, an upper dental orthodontic part and a lower dental orthodontic part are planned by the dental data; more specifically, the dental data is analyzed and planned using a computer. How the upper and lower teeth of the user are corrected.

Next, as shown in FIG. 1 and FIG. 2a, in step S105, the upper row of orthodontic portions and the lower row of orthodontic portions are respectively formed into an elastic upper correcting cuff 10 and an elastic lower correcting cuff 20, wherein The material of the elastic upper correcting cuff 10 and the elastic lower correcting cuff 20 is preferably ethylene/vinyl acetate (EVA) or a polymer mixed with cotton, rayon and rubber, which has better properties. Elastic coefficient.

Next, as shown in FIGS. 1 and 2b, in step S107, the elastic upper correcting cuff 10 is placed on an upper fixed mold 1, and the elastic lower correcting cuff 20 is placed on the lower fixed mold 2.

Next, as shown in FIG. 1 and FIG. 2c, in step S109, the elastic upper correcting cuff 10, the elastic lower correcting cuff 20 and an elastic connecting body 30 are heated to 180-280 ° C to correct the elasticity. The dental mouthpiece 10, the elastic lower correcting braces 20 and the elastic connecting body 30 are in a molten state; wherein, the heating is preferably heated to 200-230 ° C; in addition, in order to cooperate with the elastic upper correcting braces 10 and the elastic lower correcting braces 20, The elastic connecting body 30 is preferably an ethylene/vinyl acetate copolymer (EVA) or a polymer blended with cotton, rayon and rubber.

Next, as shown in FIGS. 1 and 2d, in step S111, the outer edge of the elastic upper correcting cuff 10 is fused or pressed to the top of the elastic connecting body 30, and the elastic lower correction is performed. The outer edge of the mouthpiece 20 is fused to the bottom of the elastic connector 30 in a meandering or pressing manner. Thereby, the elastic upper correcting cuff 10, the elastic lower correcting cuff 20 and the elastic connecting body 30 are integrated into one body. Here, it should be understood that when the elastic upper correcting cuff 10, the elastic lower correcting cuff 20 and the elastic connecting body 30 are fused by pressing or pressing, the upper fixed mold 1 and the lower fixed mold 2 are The arrangement prevents the elastic upper correcting cuff 10 and the elastic lower correcting cuff 20 from corresponding to the internal deformation of the upper and lower teeth of the user.

Finally, as in FIG. 1 and FIG. 2e, in step S113, the upper fixed mold 1 and the lower fixed mold 2 are removed to obtain an invisible corrective braces 100.

As shown in FIG. 3, when the user bites the invisible correcting cuff 100, the elastic structure of the elastic upper correcting cuff 10 and the elastic lower correcting cuff 20 is forced to correct the upper row of teeth and the lower row of teeth; in other words When the position of the upper row of teeth and the lower row of teeth has not been moved and twisted to the position of the elastic upper correcting braces 10 and the elastic lower correcting braces 20, by the force of the occlusion and the limit of the elastic structure, The upper row of teeth and the lower row of teeth are forced to move and twist to achieve the corrective effect. More specifically, by the characteristics of the material of the elastic upper correcting braces 10 and the elastic lower correcting braces 20, the force of the occlusion is combined, so that the user can quickly force the upper row of teeth and the lower part in the early stage of the corrective treatment. The teeth are moved and twisted; in the later stage of the corrective treatment, the corrective effect can be effectively maintained.

It can be seen from the above that since the invisible braces 100 do not correct the upper row of teeth and the lower row of teeth only by their own elastic structure, the upper row of teeth and the lower row of teeth must be corrected in accordance with the force of the bite; Therefore, when the user has a missing tooth, the effect of correcting other teeth is not affected. In other words, the invisible correcting braces 100 can be provided to more users than the conventional invisible braces. To correct it.

In addition, since the elastic upper correcting braces 10, the elastic lower correcting braces 20 and the elastic connecting body 30 are simple in structure and preferably transparent, when the user uses the invisible correcting braces 100, the appearance is beautiful and easy. It is clean and not easy to scratch the characteristics of the user's mouth.

Furthermore, when the elastic upper correcting cuff 10 and the elastic lower correcting cuff 20 respectively correct the upper row of teeth and the lower row of teeth, the elastic upper correcting cuff 10 is fixed by the elastic connecting body 30 and the elastic undercorrection is performed. The relative position of the mouthpiece 20 prevents the user from being unable to engage with the lower row of teeth after the end of the corrective treatment.

In summary, the method for manufacturing the invisible corrective braces is to produce the invisible correcting braces by the above steps, and the invisible correcting braces cooperate with the user's bite to provide sufficient force to simultaneously correct the upper row of the user. The teeth and the lower teeth are used to shorten the time of the corrective treatment; in addition, the invisible corrective braces are aesthetically pleasing, easy to clean and are not easily scratched by the user's mouth; furthermore, if the user has missing teeth, It can correct other teeth; in addition, after the end of the corrective treatment, it does not affect the bite of the upper and lower teeth.
