Description

Technical Field

[0001] The utility model relates to a structure of a dental brace which can effectively reduce angle loss and increase the clamping force during operation, thereby improving the performance of the dental brace angle. Background Art

[0002] When a person's teeth are not straight, their appearance (such as protruding upper teeth with tilted teeth), function and health may be affected. Even the degree of alignment of the teeth will directly affect the chewing function. When the teeth are not aligned properly, it is often easy to cause the teeth to be unable to bite. Therefore, modern medicine has developed orthodontic technology, which uses dental braces fixed on the teeth and then uses correction wires wrapped around the braces to force the teeth to be corrected to the correct position and neatly arranged, thereby restoring the chewing function and making the appearance more beautiful.

[0003] Traditional dental braces use archwires and brackets to apply corrective force to the teeth. The archwire can be pre-shaped and connected to the teeth through brackets fixed on the surface of the teeth. When it is installed, the archwire will elastically deform to accommodate the malpositioned teeth. The archwire is elastic and applies force to the teeth through the brackets to align the teeth with the archwire in a pre-shaped form. At this time, the archwire will continue to exert force on the teeth and gradually push the teeth to the corrected position. When using self-ligating braces, the archwire can slide more freely in the bracket slot, thereby achieving corrective tooth movement for the patient with less pressure and discomfort.

[0004] However, the above-mentioned archwire still has the following problems and defects when used and needs to be improved:

[0005] Most common archwires are rectangular or circular. The circular shape is used to align teeth, but it cannot adjust protruding teeth inward. Rectangular archwires, on the other hand, can take advantage of the angled latch to apply force to adjust teeth inward. However, a rectangle only has four corners, so the latch force, angle, and contact point still need to be improved. Utility Model Content

[0006] The purpose of the present invention is to provide a structure of a dental brace which can effectively reduce angle loss during operation and increase the clamping force to improve the performance of the dental brace angle.

[0007] The main purpose of the present invention is to provide a stronger clamping force when the archwire body is engaged with the archwire slot of the dental braces by means of at least five angled portions on the archwire body and at least one pair of non-parallel side walls, thereby effectively improving the force application point and reducing angle loss, making the angle of the dental braces more obvious and sufficient in performance and improving the beauty of the teeth arrangement.

[0008] The main structure of the present invention that can achieve the above-mentioned main purpose includes an archwire body for being set in a dental brace, wherein the archwire body has at least five corner portions, and each corner portion has a side wall between them, wherein at least one pair of side walls are non-parallel surfaces to each other. Thereby, when the archwire body is placed in the dental brace, the at least five corner portions on the archwire body will form a plurality of contact points with the inner side walls of the archwire groove on the dental brace to engage. When the contact points increase, the force application points can be effectively increased and the angle loss can be reduced, so that the angle of the dental brace is more obvious and sufficient in performance, and the teeth are arranged more beautifully.

[0009] By using the above technology, it is possible to overcome the problems of existing bow wires that only have four corners, and have poor performance in terms of locking force, angle, and contact point. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is a further detailed description of the technical means, structure and technical effects adopted by the present invention in conjunction with the accompanying drawings and preferred embodiments.

[0024] Figures 1 to 3 The three-dimensional diagram, side view and implementation diagram of the first preferred embodiment of the utility model are clearly shown in the figure. It can be seen that the new model includes:

[0025] an archwire body 1 for being disposed in a dental brace 2;

[0026] at least five angled portions 11 located on the archwire body 1; and

[0027] A plurality of side walls 12 are located between the corner portions 11, and at least one pair of the side walls 12A are non-parallel surfaces to each other.

[0028] In this embodiment, two non-parallel side walls 12A are connected to each other at one end.

[0029] Thus, when the archwire body 1 is inserted into the archwire slot 21 of the dental brace 2, its multiple angled portions 11 can engage the corners 211 within the archwire slot 21, effectively reducing angle loss. This allows for a stable engaging force when the archwire body 1 is pulled at different angles, resulting in a more stable tensioning of the archwire body 1 and better torque performance. Overall, this improves the angular performance of the dental brace 2. In other words, since the number of angled portions 11 is typically only four, when the angle at which the archwire body 1 and the dental brace 2 are mated has changed to the point where the four angled portions 11 are no longer able to engage stably, the effect of achieving uniform tooth alignment is diminished. In contrast, the archwire body 1 of the present invention has at least five angled portions. With one more angled portion 11, there is one more position that can engage the corner 211 of the archwire slot 21. This means that the archwire body 1 and the dental brace 2 can support a wider range of angles, achieving the advantages described above.

[0030] Figure 4 This is a side view of the second preferred embodiment of the new trial model. It can be clearly seen from the figure that the difference between this embodiment and the above embodiment is that the angle A between the two non-parallel side walls 12A of this embodiment is smaller than that of the above embodiment. This means that the angle A between the two non-parallel side walls 12A can be changed according to needs and is not limited. The effect achieved is the same as that of the above embodiment, so it will not be repeated.

[0031] Figure 5 This is a side view of the third preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the above embodiments is that, in this embodiment, the number of the six corner portions 11 is taken as an example. When there are six corner portions 11, the side wall 12B between the two non-parallel side walls 12A is connected to the two non-parallel side walls 12A at both ends, and the angle A presented by the connection between them is the same. It can be seen that by having more corner portions 11, better locking and fastening force can be achieved, the angle performance is better, and the angle loss can be effectively reduced.

[0032] Figure 6 This is a side view of a fourth preferred embodiment of the present invention. As can be clearly seen from the figure, in this embodiment, six corner portions 11 are used as an example. When there are six corner portions 11, the side wall 12B between two mutually non-parallel side walls 12A is connected to the two mutually non-parallel side walls 12A at both ends. This embodiment differs from the third preferred embodiment in that the two mutually non-parallel side walls 12A in this embodiment have different angles A formed when they are connected. This means that the two sides of the archwire body 1 of the present invention do not need to be symmetrical. Even if they are irregularly shaped, as long as there are at least five corner portions 11, including six, they are within the scope of protection of the present invention.

[0033] Figure 7 This is a side view of a fifth preferred embodiment of the present invention. As can be clearly seen from the figure, in this embodiment, eight angled portions 11 are used as an example. When there are eight angled portions 11, each side of the archwire body 1 has a pair of non-parallel side walls 12A (a pair is composed of two inclined side walls 12A). The non-parallel side walls 12A are inclined in different directions. In this embodiment, the side wall 12B between the two non-parallel side walls 12A is connected to the two non-parallel side walls 12A at both ends, and the angle A formed by the connection is the same. In short, the archwire body 1 of this embodiment presents an octagonal shape. Therefore, the greater number of angled portions 11 can achieve better locking and tightening force, better angle performance, and more effectively reduce angle loss.

[0034] Figure 8This is a side view of a sixth preferred embodiment of the present invention. As can be clearly seen from the figure, in this embodiment, eight corner portions 11 are used as an example. When there are eight corner portions 11, a pair of non-parallel side walls 12A (a pair is composed of two inclined side walls 12A) are provided on either side of the archwire body 1. The non-parallel side walls 12A are inclined in different directions, and a side wall 12B between the two non-parallel side walls 12A is connected to the two non-parallel side walls 12A at both ends. This embodiment differs from the fifth preferred embodiment in that the angle A formed by the connection is different. In other words, the octagonal shape of the archwire body 1 of the present invention can be asymmetrical, indicating that the two sides of the archwire body 1 of the present invention do not need to be symmetrical. Furthermore, any configuration with five or more corner portions 11 (e.g., eight in this embodiment) falls within the scope of protection of the present invention. Of course, even if the angle A on only one side is the same, but the angle A on the other side is different, it is still within the protection scope of the present invention.

[0035] Figure 9 This is a side view of the seventh preferred embodiment of the present invention. It can be clearly seen from the figure that this embodiment includes an archwire body 1 for being set in a dental brace, at least six corner portions 11 located on the archwire body 1, and several side walls 12 located between each of the corner portions 11, and at least one pair of side walls 12A are non-parallel surfaces to each other, and the side wall 12C between the pair of non-parallel side walls 12A is curved. Therefore, when the number of the present invention's six corner portions 11 is large, in addition to being fixed to the archwire slot by the mutual engagement of the corner portions 11, the curved side walls 12C can also be used to support the peripheral wall of the archwire slot, thereby achieving a perfect engagement and fixing effect.

[0036] Figure 10 This is a side view of the eighth preferred embodiment of the present invention. As can be clearly seen from the figure, this embodiment differs from the seventh preferred embodiment in that the present embodiment has eight corner portions 11, and each side of the archwire body 1 has a pair of non-parallel side walls 12A, and each pair of non-parallel side walls 12A is inclined in different directions, and two curved side walls 12C are located between each of the non-parallel side walls 12A and are positioned opposite each other. It can be seen that the structure of the present invention is not limited, and whether four corner portions 11 are combined with curved portions 13, or eight corner portions 11 are combined with curved portions 13, they are all within the scope of protection of the present invention.

[0037] Figure 11This is a side view of the ninth preferred embodiment of the present invention. As can be clearly seen from the figure, this embodiment differs from the eighth preferred embodiment in that the number of curved side walls 12C has been increased from two to four, located on four sides of the archwire body 1. This illustrates the structural versatility of the present invention and its lack of limitations. Of course, two curved side walls 12C can also be provided, located on orthogonal sides. Overall, there is no limitation to the arrangement or number of curved side walls 12C.

[0038] The embodiments described above are merely illustrative descriptions of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the present invention.
