Abstract

An invisible brace with a curved auxiliary pushing structure includes an invisible brace body, a plurality of pushing surfaces are arranged on the inner side of the invisible brace body, and the pushing surfaces are virtually connected to each other to form a pair of auxiliary curved surfaces for pushing human teeth. The auxiliary curved surfaces generate various upward, downward, and external pushing forces on the back teeth and front teeth of the human lower jaw, thereby achieving the correction effect of the teeth, preventing the back teeth from retreating to the inside of the mouth, and maintaining the back teeth to move correctly to the corrected position.

Description

Invisible braces with curved auxiliary push-holding structure

The present invention relates to braces, and in particular to a brace having a curved auxiliary pushing structure, which can correct teeth.

When orthodontics are used, metal or ceramic braces are used to push and lift the teeth with metal or ceramic components to correct the teeth to the correct position. However, since the aforementioned braces have a strong foreign body sensation in the mouth, they are easy to scratch the inner wall of the mouth, and are difficult to clean and remove, and also affect the appearance when the mouth is opened. Therefore, the industry currently designs invisible braces (without the obvious exposed components of traditional braces, not referring to the appearance of the braces being transparent or opaque), which are easy to remove and clean, quick to make, no foreign body sensation, and beautiful, so many patients use them.

However, although invisible braces are designed according to the patient's teeth, and are regularly analyzed, manufactured, and replaced, the inner side of the braces exerts various forces on the teeth, such that the teeth can be gradually moved and transformed to the appropriate position and angle; however, according to the classification of human teeth, they can be divided into anterior teeth and posterior teeth. Anterior teeth refer to the six teeth in front of the human mouth, including the central incisors, lateral incisors, and canines, with a total of six teeth on both sides, while posterior teeth refer to two premolars and three molars. According to the FDI tooth position representation (FDI notation), the anterior teeth refer to the teeth in the maxillary (11-13, 21-23) and mandibular (41-43, 31-33) positions, and the posterior teeth refer to the teeth in the maxillary (14-18, 24-28) and mandibular (44-48, 34-38) positions.

When orthodontic treatment is performed, especially when the lower jaw posterior teeth move forward, they will exert a thrust on the front teeth, which in turn will cause the front teeth to be forced to retract into the oral cavity, or even cause the posterior teeth to rotate and tilt toward the front teeth (as shown in Figure 8), thus reducing the correction effect.

In view of this, how to solve the above problems is the primary issue that this invention aims to solve.

One of the main purposes of the present invention is to provide an invisible brace with a curved auxiliary push-holding structure, which can allow the back teeth of the human oral cavity to move forward and prevent the front teeth from retreating to the inside of the oral cavity, thereby achieving the correction effect of the teeth.

To achieve the above-mentioned purpose, the invisible braces with curved surface auxiliary pushing and holding structure of the present invention include: an invisible braces body, which is divided into a front tooth area and a back tooth area according to the arrangement of human teeth; at least one front tooth pushing and holding surface is provided on the inner side of the invisible braces body in the front tooth area, and the front tooth pushing and holding surface generates a downward thrust and a downward thrust to the front teeth at the corresponding position of the human lower jaw, that is, the front tooth pushing and holding surface that generates a downward thrust to the front teeth at the corresponding position of the human lower jaw is provided on the inner side of the invisible braces body (it can be understood that the front tooth pushing and holding surface is provided on the inner side of the invisible braces body, which generates a downward thrust to the front teeth at the corresponding position of the human lower jaw, and the front tooth pushing and holding surface ... The inner side of the invisible brace body is provided with a relatively convex or concave structural surface for a specific tooth, thereby generating a pushing or pulling force on the tooth; and an attachment is provided on the tooth surface, and a groove is provided on the inner side of the invisible brace body to engage with the attachment, so that the tooth can cooperate with the attachment and receive the pushing or pulling force of the invisible brace body); the inner side of the invisible brace body is provided with at least one first posterior tooth pushing surface and at least one second posterior tooth pushing surface in the posterior tooth area, the first posterior tooth pushing surface generates an upward thrust on the posterior teeth at the corresponding position of the human lower jaw, and the second ... The tooth holding surface generates a downward thrust against the posterior teeth at the corresponding position of the human lower jaw, and the first posterior tooth holding surface is located between the anterior tooth holding surface and the second posterior tooth holding surface; the anterior tooth holding surface, the first posterior tooth holding surface, and the second posterior tooth holding surface are virtually connected to each other, and a pair of auxiliary curved surfaces for human tooth holding are formed on the inner side of the invisible brace body. The auxiliary curved surface can prevent the anterior teeth from retreating to the inside of the oral cavity when the posterior teeth move toward the anterior teeth for correction; this is because when the posterior teeth at the second posterior tooth holding surface need to move forward for correction, the first posterior tooth holding surface will be affected. The posterior teeth at the face will affect the anterior teeth of the front teeth, so according to the inertial force of the moving posterior teeth to the front, they must be given a downward force. The posterior teeth in front of the moving posterior teeth must be given an upward force to avoid squeezing and dislocation, and the anterior teeth must be given a downward force to the outside of the mouth to avoid retreating to the inside of the mouth. Therefore, they are connected to each other as the auxiliary curved surface on the inside of the invisible braces body (of course, the auxiliary curved surface path can be designed to generate various directions of force on the teeth), which produces a correction effect on the teeth.

Furthermore, a fixing piece is provided for the posterior teeth, and the fixing piece is connected to the upper jaw of the human body obliquely in front of the posterior teeth by a tension piece, so as to make the posterior teeth produce a corrective movement toward the anterior teeth; because the posterior teeth are affected by the tension piece, a force will be generated in the upper jaw and the anterior teeth direction, so the posterior teeth at this location need to be supplemented by the curved surface to apply downward force to offset the upward force generated by the tension piece.

Furthermore, the posterior teeth that are corrected and moved toward the anterior teeth refer to the posterior teeth located at the second posterior tooth thrust surface.

The above-mentioned purposes and advantages of the present invention can be easily understood from the detailed description and accompanying drawings of the following selected embodiments.

First, please refer to Figures 1-3, which are the invisible braces with curved auxiliary push-holding structure provided by the present invention, including: an invisible braces body 1, which is divided into an anterior tooth area 11 and a posterior tooth area 12 according to the arrangement of human teeth. Figure 1 shows the teeth of the upper and lower jaws of the human body, the front three teeth correspond to the anterior tooth area 11, and the back four teeth correspond to the posterior tooth area 12. It can be seen that there is a conspicuous gap between the molars and the premolars, and the front teeth are also slightly crooked, so the molars must be moved and corrected towards the anterior tooth area 11 by applying force, so that the teeth are closely and neatly arranged without generating too large a gap; the invisible braces body 1 is provided with a At least one front teeth pushing surface 111, which generates a downward and external thrust to the front teeth at the corresponding position of the human lower jaw. The front teeth pushing surface 111 can be understood as being designed according to the human teeth, so that the inner side of the invisible braces body 1 acts as a relatively convex or concave structural surface on a specific tooth (so the front teeth pushing surface 111 is real, not an imaginary structure), thereby generating a force to push or pull the tooth; and the tooth surface is provided with an attachment, and the inner side of the invisible braces body 1 is provided with a groove that engages with the attachment, so that the tooth can cooperate with the attachment and be pushed or pulled by the invisible braces body 1.

The invisible brace body 1 is provided with at least one first posterior tooth holding surface 121 and at least one second posterior tooth holding surface 122 on the inner side of the posterior tooth area 12. The first posterior tooth holding surface 121 generates an upward thrust to the posterior teeth at the corresponding position of the human mandible, and the second posterior tooth holding surface 122 generates a downward thrust to the posterior teeth at the corresponding position of the human mandible, and the first posterior tooth holding surface 121 is located at the anterior tooth holding surface 11. 1 and the second posterior tooth holding surface 122; as shown in Figures 1 and 3, the posterior teeth (molars) of the lower jaw correspond to the second posterior tooth holding surface 122, and the posterior teeth (molars) correspond to the first posterior tooth holding surface 121, so the posterior teeth (molars) will be pushed downward by the second posterior tooth holding surface 122, and the posterior teeth (molars) will be pushed upward by the first posterior tooth holding surface 121.

The posterior teeth are provided with a fixing member 2, and the fixing member 2 is connected to the upper jaw of the human body obliquely in front of the posterior teeth by a tension member 3, so as to make the posterior teeth produce a correction movement toward the anterior teeth; because the posterior teeth are affected by the tension member 3, a force will be generated in the upper jaw and the anterior teeth direction, so the posterior teeth at this location need the second posterior teeth pushing surface 122 to apply a downward force to offset the upward force generated by the tension member 3, and the posterior teeth that are corrected and moved toward the anterior teeth refer to the posterior teeth located at the second posterior teeth pushing surface 122; as shown in Figures 1 and 2, the outer side of the posterior teeth (molars) The fixing member 2 is provided, and the tension member 3 is connected to the upper jaw obliquely in front of the posterior teeth (the upper jaw connection can be an additional component outside the invisible brace body 1 of the upper jaw), so that the tension member 3 can generate an oblique pulling force on the posterior teeth at the second posterior teeth holding surface 122, that is, the component pulling force of the posterior teeth moving forward and the upward component pulling force, so that the posterior teeth (molars) can move forward to correct and eliminate the inter-tooth gap, and the second posterior teeth holding surface 122 generates a downward thrust on the posterior teeth (molars) to offset the upward component pulling force generated by the tension member 3 on the posterior teeth.

As shown in FIG. 1 and FIG. 3, the front teeth holding surface 111, the first back teeth holding surface 121, and the second back teeth holding surface 122 are virtually connected to each other, and a pair of auxiliary curved surfaces 4 for human teeth holding are formed on the inner side of the invisible brace body 1. The auxiliary curved surface 4 can prevent the front teeth from retreating to the inside of the oral cavity when the back teeth move toward the front teeth for correction. This is because when the back teeth at the second back teeth holding surface 122 move forward for correction, the back teeth at the first back teeth holding surface 121 are affected, and the front teeth at the front teeth holding surface 111 are also affected. Therefore, according to the inertial movement force of the moving back teeth to the front, a certain amount of force must be given. The posterior teeth in front of the posterior teeth to be moved must be given a force to pull upward to avoid squeezing and dislocation, and the anterior teeth must be given a force downward and to the outside of the oral cavity to avoid retreating to the inside of the oral cavity. Therefore, the auxiliary curved surface 4 (the auxiliary curved surface 4 can be designed to exert forces on the teeth in various directions) connected to each other on the inner side of the invisible brace body 1 produces a correction effect on the teeth; as shown in Figures 1, 4-6, Figure 4 is a schematic diagram of human mandibular teeth (light color), Figure 5 is a schematic diagram of the invisible brace body 1 of the present invention for the mandibular (dark color), and Figure 6 is a schematic diagram of the invisible brace body 1 of the present invention for the mandibular (dark color), and Figure 5 is a schematic diagram of the invisible brace body 1 of the present invention for the mandibular (dark color). The invisible brace body 1 of the lower jaw in FIG. 1 is combined with the lower jaw teeth of the human body in FIG. 4, so that the auxiliary curved surface 4 of the invisible brace body 1 (including the front teeth holding surface 111, the first back teeth holding surface 121, and the second back teeth holding surface 122) protrudes outside the lower jaw teeth of the human body (the dark part), and the front teeth holding surface 111, the first back teeth holding surface 121, and the second back teeth holding surface 122 are used together with FIG. 1 and FIG. 2 to express the holding force generated by the front teeth holding surface 111, the first back teeth holding surface 121, and the second back teeth holding surface 122 on each front tooth and back tooth; and FIG. 7 (also assisted by FIG. 1) shows that when the back teeth (molars) of the present invention move forward for correction, because the front teeth holding surface 111 , the first posterior teeth holding surface 121, and the second posterior teeth holding surface 122 have an auxiliary correction effect. When the posterior teeth (molars) move, they are pressed downward by the second posterior teeth holding surface 122 (in the direction of the large arrow) to offset the upward component pulling force (in the direction of the small arrow) of the tension member 3, so the posterior teeth (molars) will not tilt forward, and the posterior teeth are stably maintained to move correctly to the corrected position. The posterior teeth (premolars) are forced downward by the first posterior teeth holding surface 121 to prevent the posterior teeth (molars) from squeezing and tilting them, and the front teeth holding surface 111 assists in ensuring that the front teeth will not retract into the oral cavity, thereby correcting the correction effect of the teeth.

The disclosure of the above embodiments is only used to illustrate the present invention, not to limit the present invention, so any changes in numerical values or replacement of equivalent components should still fall within the scope of the present invention.

In summary, those who are familiar with this technology should be able to understand that this invention can indeed achieve the above-mentioned purpose and actually complies with the provisions of the Patent Law, so they can apply for it in accordance with the law.
