Description

Technical Field

[0001] The present application relates to the field of dental orthodontics, and in particular to an orthodontic bracket traction hook with an arcade-style buckle and an orthodontic bracket. Background Art

[0002] At present, the orthodontic bracket traction hook commonly used in orthodontic clinics is designed on the ligature wing of the orthodontic bracket and is an integral part of the bracket body. The inventor found that although the above design brings convenience to the clinic, it also brings the following problems to the clinic: 1. Before installing the bracket, the orthodontic clinician must consider in advance whether to use an orthodontic bracket with a hook. If not, then a traction hook must be clamped or installed on the dental arch wire again when needed in subsequent treatment. If an orthodontic bracket with a hook is selected, it will cause more or less interference in the subsequent treatment, and the orthodontic bracket will basically not be replaced in the middle, so this interference will exist throughout the entire treatment cycle; 2. There are two types of traction hooks available on the market: clamping type and adjustable type. Both are used to fix on the dental arch wire between two teeth, and the clamping type traction hook is easy to cause the dental arch wire to bend and deform and the traction hook to loosen and slip after clamping, while the adjustable type is easy to cause loosening or falling off. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] refer to Figures 1 to 5 The present application discloses an orthodontic bracket 2 traction hook 1 with an arcade-style buckle, which is used to be installed on the orthodontic bracket 2, including: a clamping portion 11 cooperating with the orthodontic bracket 2 and a traction portion 12 extending from the clamping portion 11 back to the orthodontic bracket 2; the clamping portion 11 includes a main body 111 and two clamping arms 112 extending from the main body 111, and the two clamping arms 112 extend to both sides of the orthodontic bracket 2.

[0030] The clamping arm 112 and the body 111 form a semi-enclosed structure to form a so-called arcade-style buckle, thereby realizing the connection and release of the orthodontic bracket 2. Compared with the traction hook 1 fixed on the ligature wing, the traction hook 1 in this embodiment can be flexibly set, and the traction hook 1 can be installed or removed during the treatment process, and the type of the traction hook 1 can also be adjusted to meet different treatment processes; compared with the traction hook 1 installed on the arch wire, the traction hook 1 in this embodiment does not need to act directly on the dental arch wire, so it will not cause the problem of dental arch wire deformation, loosening and slipping during clinical use. The traction hook 1 in this embodiment is directly connected to the orthodontic bracket 2, the installation effect is good, and the traction force application effect is direct.

[0031] In terms of the specific connection method, in one embodiment, the main body 111 and the two clamping arms 112 form a U-shape and the interior is used to accommodate the orthodontic bracket 2. The two clamping arms 112 are provided with anti-slip structures 113 arranged opposite to each other. The anti-slip structures 113 are used to cooperate with the orthodontic bracket 2 to prevent the clamping portion 11 and the orthodontic bracket 2 from separating.

[0032] The U-shaped structure formed by the body 111 and the two clamping arms 112 can wrap around the orthodontic bracket 2, thereby preventing the traction hook 1 from being displaced from the orthodontic bracket 2 when the traction hook 1 is subjected to force, and reducing the working load of the anti-slip structure 113. The anti-slip structure 113 is used to transmit the traction force exerted on the traction hook 1 to the orthodontic bracket 2 while preventing the engagement portion 11 from being separated from the orthodontic bracket 2, thereby achieving the traction effect of the traction hook 1. Of course, the traction hook 1 can also achieve the transmission of traction force through other structures.

[0033] Regarding the specific setting of the anti-slip structure 113, in one embodiment, the anti-slip structure 113 is a positioning protrusion arranged on the side of the clamping arm 112 facing the orthodontic bracket 2, and the positioning protrusion is provided with a guiding inclined surface 1131 on one side of the U-shaped opening of the clamping part 11, and a stop surface 1132 on the other side.

[0034] The positioning function of the positioning protrusion is realized by the stop surface 1132, and the stop surface 1132 and the orthodontic bracket 2 abut against each other to prevent the positioning protrusion from falling out of the constraint area. The guiding slope 1131 can be used for the installation of the traction hook 1. When the orthodontic bracket 2 interacts with the guiding slope 1131, the two clamping arms 112 can be driven to move backward to open the U-shaped structure formed by the body 111 and the two clamping arms 112, so as to facilitate the anti-slip structure 113 to enter the preset position.

[0035] In order to facilitate the installation of the towing hook 1 , in one embodiment, the end of the clamping arm 112 facing away from the body 111 is radially reduced and smoothly transitions to the guiding slope 1131 .

[0036] The radially reduced end portion itself can also play a guiding role, and can facilitate the operation of the clinician in cooperation with the guiding inclined surface 1131. At the same time, the radially reduced end portion can also provide a certain operating space, which can be used to drive the two clamping arms 112 to move backwards to achieve special functions under special circumstances. For example, in the scheme shown in the figure, the end of the clamping arm 112 facing away from the body 111 forms a push-off end 115, which can be used to disassemble the traction hook 1.

[0037] It is not difficult to understand from the above description that the installation and removal of the towing hook 1 is mainly through the relative movement of the two clamping arms 112, so the body 111 and the two clamping arms 112 need to have a certain elasticity to complete the deformation, and the material can be selected to be a metal with higher strength or a plastic material with better elasticity, and the structure can also be optimized accordingly. For example, in one embodiment, a release groove 114 is provided on the body 111, and the release groove 114 is used to release the deformation of the body 111 when the two clamping arms 112 move back to back.

[0038] In principle, the release groove 114 is used to release the deformation of the main body 111 to facilitate the relative movement of the two clamping arms 112. In actual operation, the release groove 114 can be used as the action position for disassembling the traction hook 1. For example, when the traction hook 1 needs to be disassembled, the two clamping arms 112 can be moved back to back by using the opening pliers of the matching traction hook 1 to hold the release groove 114 to open it and drive it to expand. In detail, in one embodiment, the traction part 12 is fixedly connected to the main body 111 and a reinforcement structure 121 connected to the two is provided at the connection, and the release groove 114 is aligned with the reinforcement structure 121. The reinforcement structure 121 can be an arc-shaped part formed by the extension of its own material. This design can avoid the influence of the opening of the release groove 114 on the strength of the main body 111.

[0039] Regarding the disposition of the traction portion 12 , in one embodiment, in the normal direction of the bonding surface 21 of the orthodontic bracket 2 , the traction portion 12 is away from the bonding surface 21 from the engaging portion 11 .

[0040] The function of the traction part 12 being away from the bonding surface 21 is to form a labial outward extension structure, that is, the traction part 12 extends toward the labial position, thereby effectively preventing the traction hook 1 from pressing the gums, and the lip inclination angle design can be adjusted to any tooth position. The lip inclination angle of the traction part 12 of different types of traction hooks 1 can be flexibly adjusted.

[0041] The traction part 12 also needs to be provided with a corresponding structure to fix the traction line. In one embodiment, one end of the traction part 12 facing away from the engaging part 11 is radially expanded to form a first anti-slipping head 122. The anti-slipping head can prevent the traction line from slipping out while also avoiding the impact of radial expansion on the inner wall of the oral cavity. In the accompanying drawings, the first anti-slipping head 122 is in the form of a round head, and has a variety of designs in actual products, such as a question mark hook, a T-hook, a square hook, etc. Those skilled in the art can clearly implement the corresponding design based on this description, so it will not be repeated.

[0042] In one embodiment, at least one radial expansion of the middle portion of the traction portion 12 is formed into a second anti-slipping head 123. The design of multiple anti-slipping heads can meet different traction needs. Referring to the description of the first anti-slipping head 122 above, the second anti-slipping head 123 can also have a variety of designs, which will not be repeated.

[0043] The length of the traction part 12 can also be flexibly adjusted, see Figure 4 and Figure 5 In the embodiment, the lengths of the traction portions 12 of the two are different.

[0044] During the installation process, the traction hook 1 can be pressed from the gum of the orthodontic bracket 2 to the lower part of the ligature wing. Before pressing in, it should be noted that the traction part 12 should be spread outward toward the lips to prevent the gums from being pressed. The installed traction hook 1 can withstand a traction force of 50 to 800g.

[0045] refer to Figures 2 to 3 The present application also discloses an orthodontic bracket 2, which is equipped with a traction hook 1 according to the above technical solution. The orthodontic bracket 2 includes a mesh bottom 22 for bonding and a base 23 with an archwire groove. The base 23 is provided with a positioning structure that cooperates with the two clamping arms 112.

[0046] The positioning structure can be composed of a separate component, or can be implemented by existing structures such as gingival ligation wings. For example, in one embodiment, the two clamping arms 112 are provided with anti-slip structures 113 arranged opposite to each other, and the positioning structure includes:

[0047] The first positioning groove 231 is disposed on a side of the base 23 facing the traction portion 12 and is used to receive at least a portion of the body 111;

[0048] The second positioning groove 232 is disposed on a side of the base 23 facing away from the traction portion 12 and is used to cooperate with the anti-slip structure 113 .

[0049] The first positioning groove 231 improves the connection effect between the traction hook 1 and the orthodontic bracket 2 by accommodating the body 111 , and the second positioning groove 232 cooperates with the stop surface 1132 mentioned above to prevent the traction hook 1 from being separated from the orthodontic bracket 2 .

[0050] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0051] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
