The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 5, the application discloses an orthodontic bracket 2 traction hook 1 of a riding type buckle, which is used for being installed on an orthodontic bracket 2 and comprises a clamping part 11 matched with the orthodontic bracket 2 and a traction part 12 extending from the clamping part 11 back to the orthodontic bracket 2, wherein the clamping part 11 comprises a body 111 and two clamping arms 112 extending from the body 111, and the two clamping arms 112 extend to two sides of the orthodontic bracket 2.
The clamping arm 112 forms a semi-encircling structure with the body 111 to form a so-called upstairs-ride type buckle, thereby enabling connection and release of the orthodontic bracket 2. Compared with the traction hook 1 fixed on the ligature wing, the traction hook 1 in the embodiment can be flexibly arranged, the traction hook 1 can be installed or detached in the treatment process, the types of the traction hook 1 can be adjusted to meet different treatment processes, compared with the traction hook 1 installed on an arch wire, the traction hook 1 in the embodiment does not need to directly act on the arch wire, so that the problems of deformation and loosening and slipping of the arch wire can not be caused in clinical use, the traction hook 1 in the embodiment is directly connected with the orthodontic bracket 2, the installation effect is good, and the traction force applying effect is direct.
In a specific connection manner, in an embodiment, the body 111 and the two clamping arms 112 form a U shape and are used for accommodating the orthodontic bracket 2, the two clamping arms 112 are provided with opposite anti-falling structures 113, and the anti-falling structures 113 are used for being matched with the orthodontic bracket 2 to prevent the clamping part 11 from being separated from the orthodontic bracket 2.
The U-shaped structure formed by the body 111 and the two clamping arms 112 can wrap the orthodontic bracket 2, so that displacement generated between the traction hook 1 and the orthodontic bracket 2 when the traction hook is stressed is avoided, and the working load of the anti-falling structure 113 is reduced. The anti-falling structure 113 is used for transmitting the traction force borne by the traction hook 1 to the orthodontic bracket 2 while preventing the clamping part 11 from being separated from the orthodontic bracket 2, so that the traction effect of the traction hook 1 is realized. Of course, the towing hook 1 can also achieve transmission of towing forces by other structures.
The anti-disengaging structure 113 is specifically disposed, in one embodiment, the anti-disengaging structure 113 is a positioning bump disposed on a side of the clamping arm 112 facing the orthodontic bracket 2, one side of the positioning bump facing the U-shaped opening of the engaging portion 11 is provided with a guiding inclined surface 1131, and the other side is provided with a stop surface 1132.
The positioning function of the positioning lug is achieved through the stop surface 1132, and the stop surface 1132 abuts against the orthodontic bracket 2 to interact, so that the positioning lug is prevented from falling out of the constraint area. The guiding inclined plane 1131 can be used for installing the traction hook 1, and when the orthodontic bracket 2 acts with the guiding inclined plane 1131, the two clamping arms 112 can be driven to move back to open the U-shaped structure formed by the body 111 and the two clamping arms 112, so that the anti-falling structure 113 can conveniently enter a preset position.
In detail to facilitate the installation of the towing hook 1, in one embodiment, the end of the gripping arm 112 facing away from the body 111 is radially tapered and smoothly transitions with the lead-in ramp 1131.
The radially tapered end itself also serves as a guide, and the mating guide ramp 1131 can facilitate the operation of the clinician. While the radially reduced ends also provide some operating space for driving the two clamping arms 112 back in special situations to perform a special function. For example, in the solution shown in the figures, the end of the gripping arm 112 facing away from the body 111 forms a push-off end 115, the push-off end 115 being able to be used for detaching the towing hook 1.
As will be understood from the above description, the traction hook 1 is mainly installed and removed by the relative movement of the two clamping arms 112, so that the body 111 and the two clamping arms 112 need to have a certain elasticity to complete deformation, and a metal with higher strength or a plastic material with better elasticity can be selected in terms of materials, and can also be correspondingly optimized in terms of structure. For example, in one embodiment, the body 111 is provided with a release slot 114, and the release slot 114 is used to release deformation of the body 111 when the two clamping arms 112 move back.
The release groove 114 is used in principle to release the deformation of the body 111 to facilitate the relative movement of the two gripping arms 112, and in practice the release groove 114 can be used as an active position for the removal of the towing hook 1. For example, when the traction hook 1 needs to be disassembled, the clamp is opened by the traction hook 1 which is wanted to be matched to prop against the release groove 114 so as to prop open and drive the release groove to expand, so that the two clamping arms 112 can move back. In detail, in one embodiment, the traction portion 12 is fixedly connected to the body 111, and a reinforcing structure 121 connected to the traction portion and the body is disposed at the connection position, and the release groove 114 is aligned with the reinforcing structure 121. The reinforcing structure 121 may be an arcuate portion formed by an extension of its own material. This design can avoid the influence of the opening of the release groove 114 on the strength of the body 111.
In the arrangement of the traction portion 12, in one embodiment, the traction portion 12 is remote from the adhesive surface 21 from the engagement portion 11 in a direction normal to the adhesive surface 21 of the orthodontic bracket 2.
The function of the traction portion 12 away from the adhesive surface 21 is to form a lip-outwardly extending structure, i.e. the traction portion 12 extends to a labial position, so that the traction hook 1 is effectively prevented from pressing the gum, and the design of the inclination angle of the lip can be adapted to any tooth position. The lip angle of the traction portion 12 of the traction hook 1 of different types can be flexibly adjusted.
The traction portion 12 also needs to be provided with a corresponding structure to secure the traction wire. In an embodiment, an end of the traction portion 12 facing away from the engaging portion 11 radially expands to be the first anti-drop head 122. The anti-drop head can also avoid the influence that radial expansion probably caused to the inner wall of the oral cavity when preventing the traction wire from falling off. In the drawings, the first anti-drop head 122 is in the form of a round head, and various designs are provided in the actual product, such as a question mark hook, a T-shaped hook, a square hook, etc., and a person skilled in the art can clearly realize the corresponding design according to the description, so that the description is omitted.
In one embodiment, at least one portion of the middle of the traction portion 12 radially expands to be the second anti-drop head 123. The design of a plurality of anticreep heads can satisfy different traction needs. Referring to the description of the first anti-drop head 122, the second anti-drop head 123 can also have various designs, which will not be repeated.
The length of the traction portion 12 can also be flexibly adjusted, and the traction portion 12 of the two embodiments can be different in length with reference to fig. 4 and 5.
During the installation of the towing hook 1, the orthodontic bracket 2 is aligned and pressed from the gingiva to the lower part of the ligating wing, and before the pressing, attention should be paid, and the towing part 12 should be spread outwards to prevent pressing the gingiva. The traction hook 1 after installation can bear 50-800 g of traction force.
Referring to fig. 2 to 3, the present application also discloses an orthodontic bracket 2, which is provided with a traction hook 1 according to the above technical scheme, wherein the orthodontic bracket 2 comprises a net bottom 22 for adhesion and a base 23 provided with an archwire slot, and a positioning structure matched with two clamping arms 112 is arranged on the base 23.
The positioning structure can be composed of a single component or can be realized by the existing structures such as gingival tie wings and the like. For example, in one embodiment, the two clamping arms 112 are provided with opposite anti-falling structures 113, and the positioning structure includes:
a first positioning groove 231 provided on a side of the base 23 facing the traction portion 12 and accommodating at least a part of the main body 111;
The second positioning groove 232 is disposed on a side of the base 23 facing away from the traction portion 12 and is used for being matched with the anti-falling structure 113.
The first positioning groove 231 improves the coupling effect of the traction hook 1 and the orthodontic bracket 2 by accommodating the body 111, and the second positioning groove 232 cooperates with the above stop surface 1132 to prevent the traction hook 1 from being separated from the orthodontic bracket 2.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description. When technical features of different embodiments are embodied in the same drawing, the drawing can be regarded as a combination of the embodiments concerned also being disclosed at the same time.
The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application.
