Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings or orientations or positional relationships that the products of the present invention are conventionally placed in use, and are only used for convenience of describing the present application and simplifying the description, but do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present application. Furthermore, the terms "first," "second," and the like are used merely to distinguish one description from another, and are not to be construed as indicating or implying relative importance.

The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

In the treatment and use process of the existing orthodontic assembly, the ligature wire is sleeved on the outer side of the orthodontic bracket and is abutted against four prism parts of the orthodontic bracket, so that the ligature wire and the orthodontic bracket are not tightly combined. And because the space below the ligating wing is smaller, sometimes the ligating wire can slide from the orthodontic bracket, so that the stability of the arch wire and the orthodontic bracket can not be ensured. If the space under the tie wings (i.e., the space on the side closer to the teeth) is increased, the overall height of the orthodontic bracket is increased, resulting in poor wearing comfort.

In order to improve above-mentioned prior art ligature wire and be difficult to tie or the relatively poor problem of stability, this application embodiment provides an orthodontic bracket and includes the just abnormal subassembly of this just abnormal support groove, through addding the tie wing guide way, under the prerequisite that does not increase just abnormal support groove height for the ligature wire can overlap better and establish in just abnormal support groove outside, has guaranteed the relative stability of arch wire and just abnormal support groove.

Fig. 1 is a schematic view of an orthodontic assembly 010 according to an embodiment of the present application; fig. 2 is a schematic view of an orthodontic assembly 010 with ligature 400 removed according to one embodiment of the present disclosure. As shown in fig. 1 and 2, an orthodontic assembly 010 provided by an embodiment of the present application includes an orthodontic bracket 100, an archwire 200, a mesh bottom 300, and a ligature wire 400. Wherein the mesh bottom 300 is used for fitting fixation with the tooth surface of the tooth, which is generally the labial (i.e., outer) side tooth surface of the crown. The orthodontic bracket 100 is fixedly connected to the mesh bottom 300 by welding, such as brazing. The archwire 200 passes through the receiving slots 111 of the orthodontic brackets 100 so that its restoring force can be applied to the orthodontic brackets 100 in the case of elastic deformation, and is finally transmitted to the teeth through the mesh base 300, resulting in a corrective force. In this embodiment, the ligature 400 is sleeved on the bracket body 110 and abuts against the two end portions of the arch wire 200 extending out of the groove, so as to improve the relative stability of the orthodontic arch wire 200 and the orthodontic bracket 100. The ligature wire 400 can be a ligature ring made of plastic material and is sleeved on the bracket body 110; or a metal wire, which is bound on the outer side of the bracket body 110.

Fig. 3 is a schematic view of an orthodontic bracket 100 according to an embodiment of the present application. Referring to fig. 1 to 3, the orthodontic bracket 100 includes a bracket body 110 and a sliding cover 120, wherein the bracket body 110 has a bottom surface and a front surface opposite to each other, and four side surfaces connected in sequence. Wherein, when in use, the ground is the surface facing the teeth, and the front surface is the surface facing the labial side. The bracket body 110 is provided with an accommodating groove 111, and is specifically arranged on the front surface of the bracket body 110. The accommodating groove 111 extends along the first direction and penetrates through the bracket body 110, two ends of the accommodating groove 111 respectively penetrate out from two opposite side surfaces of the bracket body 110, and the accommodating groove 111 has a bottom surface and an opening which are opposite to each other in the depth direction. The sliding cover 120 is slidably disposed on the front surface of the slot body 110, and can selectively open or close the opening of the receiving slot 111 by sliding. The bracket body 110 is provided with a tie wing 117, and the tie wing 117 protrudes out of the side surface. The tie wings 117 function to prevent the ligature wire 400 from slipping off.

In this embodiment, by closing the slide cover 120, the orthodontic archwire 200 can be locked in the receiving slot 111 and cannot be removed from the opening of the receiving slot 111. The cross-sectional shape of the receiving groove 111 perpendicular to the first direction is rectangular. The receiving grooves 111 are rectangular, and after the arch wire 200 with the rectangular cross section penetrates into the receiving grooves 111, the arch wire 200 with the rectangular cross section can provide torque for the orthodontic bracket 100 when rotating, so that the arch wire has a tendency of rotating, and finally, teeth can be forced to generate torque movement. In other embodiments, the sliding cover 120 may not be provided, and the archwire 200 may be confined in the accommodating slot 111 only by the ligature wire 400.

It should be understood that in embodiments where torque need not be provided, the cross-sectional shape of the receiving slot 111 may be other shapes, and the cross-sectional shape of the archwire 200 may be other shapes instead of rectangular.

In this embodiment, the four sides form a ridge adjacent to each other and a tie wing guide slot 118 is provided at the juncture between the sides, thereby eliminating a portion of the ridge. The ligature 400 can be partially inserted into the tie wing guide slots 118 such that the tie wing guide slots 118 provide an expanded installation space for the ligature 400. And due to the limiting function of the guide groove 118 of the ligating wing, the stability of the ligating wire 400 is better and the ligating wire is not easy to fall off.

In this embodiment, the extending path of the tie wing guide slot 118 is arcuate, and thus the tie wing guide slot 118 has a tendency to extend circumferentially around the bracket body 110, which also conforms to the manner in which the ligature wire 400 extends, such that the ligature wire 400 is better inserted into the tie wing guide slot 118 and better conforms to the inner wall surface of the tie wing guide slot 118. Further, because ligatures 400 tend to be circular in cross-section, in this embodiment, the cross-sectional profile of the tie wing guide slot 118 perpendicular to its path of extension is arcuate, i.e., the inner wall surface of the tie wing guide slot 118 is arcuate. This further allows the ligature wire 400 to better engage the tie wing guide slots 118 and become more tightly engaged with the bracket body 110.

In the embodiment, the sliding cover 120 can slide relative to the bracket body 110 along a second direction to selectively open or close the opening of the accommodating groove 111, wherein the second direction is perpendicular to the extending direction (i.e., the first direction) and the depth direction of the accommodating groove 111. Further, the sliding cover 120 completely covers the accommodating groove 111 in the extending direction of the accommodating groove 111 in the state of closing the opening of the accommodating groove 111. The sliding cover 120 completely covers the receiving groove 111 with a large width (dimension in the first direction), has good strength, and can more stably limit the arch wire 200 in the receiving groove 111 and prevent the arch wire 200 from rotating around the axis in the second direction.

Optionally, the bracket body 110 and the sliding cover 120 may be slidably engaged by the guide rail 112 and the sliding groove 121. In this embodiment, the front surface of the bracket body 110 is provided with a guide rail 112, the sliding cover 120 is provided with a sliding groove 121, the guide rail 112 is in sliding fit with the sliding groove 121, and the sliding groove 121 is a T-shaped groove or a dovetail groove. In other embodiments, the positions of the slide rail and the slide groove 121 can be reversed. In addition, the sliding cover 120 and the bracket body 110 can perform a relative translational movement therebetween by rolling members (e.g., rollers, balls), which can reduce the sliding resistance therebetween, and therefore, the "sliding" or "sliding fit" in this application shall include various manners of performing a relative translational movement by using rolling members.

fig. 5 is a schematic view of the bracket body 110 and the elastic member 130 according to an embodiment of the present disclosure; fig. 6 and 7 are schematic diagrams illustrating the sliding cover 120 and the elastic member 130 according to an embodiment of the present disclosure. As shown in fig. 4 to 7, the orthodontic bracket 100 further includes an elastic member 130, the sliding cover 120 is further provided with a sliding fit groove 122, the elastic member 130 is disposed on the bracket body 110, and a portion of the elastic member extends into the sliding fit groove 122, two ends of the sliding fit groove 122 are respectively provided with a recess, when the sliding cover 120 slides to a limit position, the elastic member 130 abuts against the recess under the action of a restoring force to limit the sliding of the sliding cover 120; the limit positions include a position where the sliding cover 120 completely closes the opening of the receiving groove 111 and a position where the sliding cover 120 completely opens the opening of the receiving groove 111.

Specifically, in this embodiment, the elastic member 130 is an elastic U-shaped filament, the bracket body 110 is provided with the installation groove 115, the elastic member 130 is placed into the bracket body 110 from the bottom surface, and two ends of the elastic member 130 protrude from the front surface of the bracket body 110. The elastic member 130 is a U-shaped wire, so that both ends thereof can approach or move away from each other under elastic deformation. In this embodiment, the inner side of the sliding cover 120 is provided with two sliding fit grooves 122 for fitting with two ends of the elastic member 130. The sliding engagement groove 122 extends in the second direction, i.e., in the sliding direction of the sliding cover 120. When the two ends of the elastic member 130 slide to the ends of the sliding fit groove 122, it means that the sliding cover 120 slides to the open position or the closed position (i.e. two limit positions), and at this time, the elastic member 130 will be pushed into the recess by its own restoring force, so as to achieve self-locking. As shown in fig. 6, the slider cover 120 is in the open position; sliding the sliding cover 120 in the second direction may slide the sliding cover 120 to the closed position, i.e., the position shown in fig. 7.

Further, an auxiliary card slot 113 is disposed on one side of the opening of the accommodating groove 111 in the second direction, and a clamping portion 123 is disposed at one end of the sliding cover 120 in the second direction, where the clamping portion 123 can be clamped and matched with the auxiliary card slot 113.

In this embodiment, the opening width of the auxiliary card slot 113 is smaller than the inner width, the end size of the clamping portion 123 is larger than the root size of the connection sliding cover 120, and the clamping portion 123 can be clamped into the auxiliary card slot 113 or pulled out of the auxiliary card slot 113 along the second direction by using the elastic deformation of itself or the auxiliary card slot 113. It can be seen that, in this embodiment, the clamping portion 123 can be clamped into the auxiliary clamping slot 113 only by a certain external force, so as to achieve closing; meanwhile, a certain external force is required to open the receiving groove 111, and the stability of the sliding cover 120 can be improved by the arrangement. In the correction process, the orthodontic archwire 200 provides an outward pushing force to the sliding cover 120 at the inner side of the sliding cover 120, or provides a friction force to make the sliding cover 120 have a tendency of sliding and opening, but the auxiliary slot 113 and the clamping part 123 are matched to make the sliding cover 120 in a closed state more stable and not easy to fall off or open. Therefore, the auxiliary card slot 113 and the clamping portion 123 can better realize self-locking of the sliding cover 120.

In the present embodiment, the size of the snap-in portion 123 in the first direction is the same as the size of the slide cover 120 in the first direction. The auxiliary card slot 113 is divided into two spaced sections, and the two sections of auxiliary card slots 113 are both matched with the clamping portion 123.

In an alternative embodiment, the slot body 110 has an abutting surface, and the abutting surface is used for abutting against an end portion of the sliding cover 120 in the second direction when the sliding cover 120 closes the opening of the receiving slot 111, where the end portion is a front end of the sliding cover 120 in the closing process. The bracket body 110 is further provided with an uncovering groove 114, the uncovering groove 114 is adjacent to the abutting surface, the uncovering groove 114 is opened on one side facing the cover body and one side departing from the bottom surface of the accommodating groove 111, and when the abutting surface abuts against the sliding cover 120, the sliding cover 120 is spaced from one wall surface of the uncovering groove 114 in the second direction. Through setting up the groove 114 of uncapping for the sliding closure 120 is closing the back that targets in place, and its terminal surface is towards the groove 114 of uncapping, if need open the sliding closure 120, then can insert the groove 114 of uncapping with the instrument, and the butt then promotes the sliding closure 120 and opens on the terminal surface of sliding closure 120, makes things convenient for the sliding closure 120 to open like this. In the present embodiment, the open cover slot 114 is located at a position between two segments of the auxiliary card slot 113.

In this embodiment, the front surface of the bracket body 110 is further provided with a dot color groove 116, and the dot color groove 116 is used for filling the identification material. The marking material may be a pigment to enable the orthodontist to distinguish the orthodontic brackets 100 by color. In an alternative embodiment, the orthodontic bracket 100 may also be distinguished by the physician by lettering on the slide cover 120.

In this embodiment, the bracket body 110 of the orthodontic bracket 100 is provided with tie wing guide slots 118, and the tie wing guide slots 118 are located below the tie wings 117. Since both ends of the tie wing guide groove 118 respectively penetrate through the adjacent two side surfaces, the extension direction of the ligature wire 400 can be conformed, so that the ligature wire 400 is embedded into the tie wing guide groove 118 when being bound to the bracket body 110. Through setting up tie wing guide way 118, eliminate some edges and parts of side junction, provide certain space for the installation of ligature silk 400 to can restrict the removal of ligature silk 400 effectively, make it firm and difficult landing.
