Description

Technical Field

[0001] The present invention 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 solution has the following problems and defects when used in self-locking braces and needs to be improved:

[0005] Because the groove of the bracket is generally rectangular, when used with a rectangular archwire, the archwire will use the side corners to engage with the inner wall of the groove to form a torque to express the angle of the self-ligating corrector. However, a rectangle has only four corners, so the engagement force, angle, and contact point need to be improved. Utility Model Content

[0006] In order to solve the above technical problems, the present invention provides a structure of a dental brace which can effectively reduce angle loss and increase the clamping force during operation, thereby improving the angle performance of the dental brace.

[0007] The main purpose of the present invention is to improve the locking effect of the archwire in the archwire slot by designing at least six angle portions of the ring wall and several side walls arranged corresponding to each of the angle portions, as well as at least one pair of side walls as non-parallel surfaces to reduce the loss of angles, make the angle performance more significant, and contribute to the correction effect of teeth.

[0008] The structure of the present invention capable of achieving the above-mentioned main purpose includes a fixing device for being set on the outer tooth surface of a tooth, the fixing device having an archwire groove, and a cover body for covering the archwire groove is movably provided on the fixing device. When covering the archwire groove, the cover body and the archwire groove together surround a ring wall for accommodating the archwire, and the ring wall includes at least six corner portions and several side walls located between each of the corner portions, and at least one pair of side walls are non-parallel to each other.

[0009] When the user wants to perform orthodontic treatment, he or she can first put the archwire into the archwire slot and then close the cover. At this time, the archwire will be firmly confined in the archwire slot, and the corners of the archwire will produce a mutual locking effect with the corner portion or the side wall. In short, the corners will be supported on the corner portion or the side wall. In particular, the corner portion of the present invention is at least six or more side walls, so the archwire can have more locking fulcrums and stress when locking, thereby achieving the above-mentioned technical effect.

[0010] The above solution can overcome the problem that existing self-locking braces only have four corners and poor performance in terms of locking force, angle, and contact point. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is a further detailed description of the technical means, structure and technical effects of the present invention in conjunction with the accompanying drawings and preferred embodiments.

[0023] Figures 1 to 3 The three-dimensional perspective view, side view and implementation diagram of the first preferred embodiment of the utility model are shown in the figure. It can be clearly seen from the figure that the new model includes:

[0024] A fixing device 1 for being arranged on the outer tooth surface of a tooth, having an archwire groove 11; and

[0025] A cover 12 is movably mounted on the fixture 1 to cover the archwire slot 11. When covering the archwire slot 11, the cover 12 and the archwire slot 11 together form a surrounding wall 13. The surrounding wall 13 is configured to accommodate an archwire 2. The surrounding wall 13 includes at least six corner portions 131 and a plurality of side walls 132 located between the corner portions 131. At least one pair of the side walls 132A are non-parallel to each other.

[0026] The fixing device 1 has a bottom pattern 14 on the side facing away from the cover 12 , and is inclined.

[0027] The cover 12 can be moved laterally to cover the bowwire slot 11 .

[0028] The dental braces of the present invention are self-locking braces, and can be active self-locking braces or passive self-locking braces. This embodiment takes a passive self-locking brace as an example.

[0029] In this embodiment, six corner portions 131 and six side walls 132 are used as an example.

[0030] In this embodiment, the two non-parallel side walls 132A are located on the side away from the cover 12, and the side wall 132 between the two non-parallel side walls 132A is connected to the two non-parallel side walls 132A at both ends, and the angle A formed by the connection is the same as in this embodiment. The so-called pair refers to two side walls 132A forming a pair, and the two side walls 132A are not directly connected together, that is, there is another side wall 132 between them. This arrangement can be referred to in the accompanying drawings.

[0031] When the user's teeth are generally messy and protruding, and need to be corrected, the bottom pattern 14 of the fixing device 1 can be faced to the outer surface of the teeth and attached, and then a circular archwire is placed on the archwire groove 11, and finally the cover body 12 is closed. At this time, the user can use the archwire to correct the arrangement of the teeth so that they are aligned. In the second stage, the circular archwire is removed and the rectangular archwire 2 is inserted. The installation is completed after the cover 12 is closed. At this time, the archwire 2 has four corners 21 due to its rectangular shape. Because the annular wall 13 has six corner portions 131 and several side walls 132, when the archwire 2 is in the archwire groove 11 and is pulled by force, the corners 21 of the archwire 2 cooperate with the corner portions 131 of the archwire groove 11 to produce more engaging contact points. When there are more engaging contact points, the torsional force of the archwire 2 during operation can be greater, and the performance in terms of angle is more prominent, effectively reducing the angle loss.

[0032] Therefore, by using the rectangular archwire 2, plus the necessary torque and angle, the protruding tooth can be pulled back inward. It is worth mentioning that the non-parallel surface means that the side wall 132A is an inclined surface. When the inclined surface is generated, it means that the volume of the archwire groove 11 is smaller. At this time, it is more cost-effective in manufacturing, the manufacturing process is more convenient, and it is more convenient for doctors to operate in the clinic.

[0033] Figure 4 This is a side view of a second preferred embodiment of the present invention. It can be clearly seen from the figure that this embodiment differs from the above embodiments in that the side wall 132B between the two non-parallel side walls 132A of this embodiment is connected to the two non-parallel side walls 132A at both ends, and the angles A formed by the connection are different. This means that the two sides of the bowwire slot 11 of the present invention do not need to be symmetrical. Even if it is an irregular shape, as long as it has six or more corner portions 131, it falls within the scope of protection of the present invention.

[0034] 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 embodiment is that the two non-parallel side walls 132C of this embodiment are located on the cover body 12, and the side wall 132D between the two non-parallel side walls 132C is connected to the two non-parallel side walls 132C at both ends, and the angle A presented by the connection between them is the same. It can be seen from the figure that the annular wall 13 surrounded by the cover body 12 and the bow wire groove 11 also has six corner portions 131 and multiple side walls 132 corresponding to the corner portions 131. It can be seen that the two non-parallel side walls 132C of the present invention can also be established on the cover body 12, and the effect achieved is the same as that described in the above embodiment, which will not be repeated here.

[0035] Figure 6 This is a side view of a fourth preferred embodiment of the present invention. As can be clearly seen in the figure, two non-parallel side walls 132C are located on the cover 12. However, this embodiment differs from the above embodiments in that a side wall 132D between the two non-parallel side walls 132C is connected to the two non-parallel side walls 132C at both ends, and the angles A formed by the connection are different. This indicates that the two sides of the bow wire slot 11 of the present invention do not need to be symmetrical. Even if it is an irregular shape, as long as it has six or more corner portions 131, it falls within the scope of protection of the present invention.

[0036] Figure 7 This is a side view of a fifth preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the above embodiment is that the corner portions 131 of the ring wall 13 of this embodiment are eight, so when there are eight corner portions 131, the ring wall 13 is respectively at the two side walls 132A on the side away from the cover body 12 and the two side walls 132C on the cover body 12, all of which are inclined in different directions from each other, and the side wall 132B between the two non-parallel side walls 132A on the side away from the cover body 12 is at both ends. The side walls 132A are connected to the two non-parallel side walls 132A, and the angle A formed by the connection is the same. The side wall 132D between the two non-parallel side walls 132C on the cover body 12 is connected to the two non-parallel side walls 132C at both ends, and the angle A formed by the connection is the same. In short, the annular wall 13 of this embodiment has an octagonal shape as a whole. Therefore, better locking and fastening force can be achieved by having more corner portions 131, better angle performance, and more effective reduction of angle loss.

[0037] Figure 8 This is a side view of the sixth preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the fifth preferred embodiment is that the side wall 132B between the two non-parallel side walls 132A on the side away from the cover body 12 is connected to the two non-parallel side walls 132A at both ends, and the angles A presented by the connection are different. The side wall 132D between the two non-parallel side walls 132C on the cover body 12 is connected to the two non-parallel side walls 132C at both ends, and the angles A presented by the connection are different. In other words, the octagonal shape of the annular wall 13 of the present invention can be asymmetrical, indicating that the two sides of the bow wire slot 11 of the present invention do not need to be symmetrical, and more than six corner portions 131 (such as eight for example in this embodiment) fall within the protection scope 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 also falls within the protection scope of the present invention.

[0038] Figure 9This is a side view of the seventh preferred embodiment of the present invention. It can be clearly seen in the figure that the annular wall 13 has at least one deformation portion 1321 on at least one pair of side walls 132A that are non-parallel to each other. The deformation portion 1321 of this embodiment is concave and convex as an example. Through the design of the deformation portion 1321, the arch wire can have more latching contact points, thereby achieving better latching fastening force, effectively reducing angle loss, and improving angle performance.

[0039] 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.
