Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to a self-locking bracket that is easy to ligate. Background Technology

[0002] In the field of orthodontic instruments, self-ligating brackets are one of the core instruments in modern orthodontics. They use built-in locking mechanisms to fix the orthodontic archwire, replacing the ligatures or rubber bands required by traditional brackets. Compared to traditional brackets, self-ligating brackets theoretically provide lower friction, potentially leading to faster tooth movement, gentler corrective forces, and longer intervals between appointments. Therefore, they are widely used in orthodontic treatment. However, existing traditional passive self-ligating brackets have significant shortcomings. Their locking plates are small, creating numerous gaps when fitted with the bracket body. These gaps easily trap food debris, making cleaning difficult and potentially causing oral hygiene problems, thus affecting the safety of the treatment process. Simultaneously, existing overlay passive self-ligating brackets also have drawbacks that urgently need to be addressed. Their limited ligation space and lack of four prominent wing structures make ligation operations inconvenient, affecting the convenience and efficiency of orthodontic treatment. These problems negatively impact the effectiveness and user experience of self-ligating brackets and urgently require improvement through structural design optimization. In view of this, a self-locking bracket that facilitates ligation is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a self-locking bracket that facilitates ligation, thereby simplifying the ligation process.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A self-locking bracket for easy ligation includes a bracket body and a self-locking sliding cover. The self-locking sliding cover is slidably disposed on the bracket body. The bracket body has a threaded groove. The side of the self-locking bracket has a first groove and a second groove. The first groove extends from the upper surface of the self-locking sliding cover to the bracket body. The first groove and the second groove are in opposite positions. The first groove and the second groove have recessed grooves. The recessed grooves have positioning holes. The recessed grooves have fixing pieces. The top of the fixing pieces has a ligation limiting protrusion, and the bottom has a fixing cylinder. The fixing cylinder is inserted into the positioning holes. There are two or more positioning holes, which are symmetrically arranged about the central axis of the recessed grooves. The ligation limiting protrusions are arranged in pairs, and the ligation limiting protrusions of the same pair are symmetrically arranged about the central axis of the recessed grooves.

[0005] In a preferred embodiment, there are two or more positioning holes, and the fixing cylinder is provided in a one-to-one correspondence with the positioning holes.

[0006] In a preferred embodiment, the support body is provided with a slider, the slider is L-shaped, and the self-locking sliding cover is provided with a groove that cooperates with the slider.

[0007] In a preferred embodiment, the support body is provided with a mounting hole, a positioning rod is provided in the mounting hole, and a limiting groove is provided at the bottom of the self-locking sliding cover, and the positioning rod is inserted into the limiting groove.

[0008] In a preferred embodiment, the upper surface of the self-locking sliding cover and the upper surface of the support body form a common upper surface, and an opening groove is provided on the upper surface, the opening groove being located on the support body.

[0009] In a preferred embodiment, a ligation limiting interval is formed between the same pair of ligation limiting protrusions.

[0010] In a preferred embodiment, the ligation limiting protrusions of the same pair have the same protrusion height, while the protrusion heights of different pairs of ligation limiting protrusions are different. The ligation limiting protrusions located on the same side of the central axis of the sinking groove are arranged in descending order of height.

[0011] In a preferred embodiment, except for the ligation limiting protrusion furthest from the central axis of the sinking trough, the top of the other ligation limiting protrusions on the side furthest from the central axis of the sinking trough is provided with a protruding sharp portion.

[0012] In a preferred embodiment, the ligation limiting protrusion is elongated, and the top edge of the ligation limiting protrusion has an arc-shaped chamfer.

[0013] Compared with existing technologies, this utility model provides a self-ligating bracket that facilitates ligation. The bracket body and a sliding self-ligating cover cooperate with each other. The sliding action of the self-ligating cover along the bracket body opens and closes the wire groove, providing a convenient channel for the insertion and placement of the orthodontic archwire and reliably limiting the archwire to ensure its stable function during treatment. The self-ligating bracket features a first groove and a second groove on its side, with the first groove extending from the upper surface of the self-ligating cover to the bracket body. This design naturally forms four distinct wing structures on the side of the bracket, effectively compensating for the inconvenience of ligation caused by the limited ligation space and lack of obvious wing structures in traditional overlay passive self-ligating brackets. It provides ample space and convenient force support for ligation operations. The recessed grooves within the first and second grooves provide a suitable installation and support space for the fixation piece, enabling circumferential limiting of the fixation piece and preventing displacement in the dynamic oral environment. The fixation tube at the bottom of the fixation piece and the groove within the recessed groove... The positioning holes are symmetrically arranged about the center axis of the recess, forming a detachable connection structure between the fixation piece and the bracket, providing a convenient basis for the installation and replacement of the fixation piece. Two or more positioning holes are symmetrically arranged about the center axis of the recess, and with the one-to-one insertion of the fixation cylinder, the connection points between the fixation piece and the bracket are symmetrically distributed. The mechanical properties of the symmetrical structure ensure even force distribution, avoiding loosening and damage caused by stress concentration at a single connection point, significantly improving the stability and reliability of the fixation piece after installation. The ligation limiting protrusions are arranged in pairs, and the same pair is symmetrical about the center axis of the recess. This optimizes the structural mechanical performance, ensuring that the force during ligation is evenly transmitted to the bracket, and also forms a symmetrical constraint on the ligation wire, ensuring accurate positioning of the ligation wire and preventing its deviation. This, in turn, ensures the directional and even transmission of additional orthodontic force. At the same time, the symmetrical structure also makes the fixation piece installation more regular and facilitates oral hygiene. The overall structural design takes into account the convenience of ligation operation, the stability of the connection, and the accuracy of orthodontic force transmission.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0026] like Figures 1 to 9As shown, a self-locking bracket for easy ligation includes a bracket body 1 and a self-locking sliding cover 7. The self-locking sliding cover 7 is slidably disposed on the bracket body 1. The bracket body 1 is provided with a wire groove 6. The side of the self-locking bracket is provided with a first groove 10 and a second groove 11. The first groove 10 extends from the upper surface of the self-locking sliding cover 7 to the bracket body 1. The first groove 10 and the second groove 11 are in opposite positions. The first groove 10 and the second groove 11 are provided with a recessed groove 12. The recessed groove 12 is provided with a positioning hole 14. The recessed groove 12 is provided with a fixing piece 16. The top of the fixing piece 16 is provided with a ligation limiting protrusion 17, and the bottom is provided with a fixing cylinder 19. The fixing cylinder 19 is inserted into the positioning hole 14. There are two or more positioning holes 14, which are symmetrically arranged about the central axis 13 of the recessed groove 12. The ligation limiting protrusions 17 are arranged in pairs, and the ligation limiting protrusions 17 of the same pair are symmetrically arranged about the central axis 13 of the recessed groove 12.

[0027] This embodiment features a self-ligating bracket designed for easy ligation. The bracket body 1 engages with a slidably mounted self-ligating cover 7. The sliding motion of the self-ligating cover 7 along the bracket body 1 opens and closes the wire groove 6, providing a convenient channel for the insertion and placement of the orthodontic archwire 24, while also reliably limiting the archwire 24 to ensure its stable function during treatment. A first groove 10 and a second groove 11 are positioned opposite each other on the side of the self-ligating bracket, with the first groove 10 extending from the upper surface of the self-ligating cover 7 to the bracket body 1. This structural design allows the bracket to... The groove side naturally forms four distinct wing structures, effectively compensating for the inconvenience of ligation caused by the small ligation space and lack of obvious wing structures in traditional cover-type passive self-locking brackets, providing ample space and convenient force support for ligation operations; the recessed groove 12 set in the first groove 10 and the second groove 11 provides a suitable installation and bearing space for the fixation piece 16, and can form a circumferential limit on the fixation piece 16, preventing the fixation piece 16 from shifting in the dynamic environment of the oral cavity; the fixation cylinder 19 at the bottom of the fixation piece 16 and the fixation in the recessed groove 12 The positioning holes 14, when inserted, form a detachable connection structure between the fixing plate 16 and the support body 1, providing a convenient basis for the installation and replacement of the fixing plate 16. Two or more positioning holes 14 are symmetrically arranged about the central axis 13 of the recess 12, and correspondingly inserted with the fixing cylinder 19, ensuring a symmetrical distribution of the connection points between the fixing plate 16 and the support body 1. This utilizes the mechanical properties of the symmetrical structure to achieve uniform force distribution, avoiding loosening and damage caused by stress concentration at a single connection point, significantly improving the stability and reliability of the fixing plate 16 after installation. The limiting protrusions 17 are designed in pairs and are symmetrical about the central axis 13 of the groove 12. This design optimizes the structural mechanical properties, ensuring that the force applied during ligation is evenly transmitted to the bracket 1. It also provides symmetrical constraint on the ligation wire, ensuring that the ligation wire is accurately positioned and preventing it from shifting. This, in turn, ensures the directional and even transmission of additional orthodontic force. At the same time, the symmetrical structure makes the fixation piece 16 more neatly installed, which is conducive to oral cleaning. The overall structural design takes into account the convenience of ligation operation, the stability of connection, and the accuracy of orthodontic force transmission.

[0028] In this embodiment, the height of the ligation limiting protrusion 17 is set between 0.2 and 0.5 mm.

[0029] In this embodiment, the positioning hole 14 is provided with a hook ring 15 on its edge, the fixing cylinder 19 includes a plurality of segments 20, the lower end of the segments 20 is provided with a hook edge 21, the fixing cylinder 19 is provided with a shape memory alloy wire 22, and the hook edge 21 and the hook ring 15 are connected in a coordinated manner. The cooperation between the fixing tube 19 and the positioning hole 14 provides the basic structure for the installation and adjustment of the fixing piece 16. The bidirectional memory alloy wire 22 utilizes its temperature response characteristics to expand under the suitable temperature in the oral cavity, causing the segments 20 of the fixing tube 19 to open. This allows the hook edge 21 at the lower end of the segment 20 to be firmly connected to the hook ring 15 on the edge of the positioning hole 14, thus achieving reliable fixation of the fixing piece 16. The fixation operation can be completed without additional tools, making it suitable for use in the oral cavity. When it is necessary to adjust or replace the fixing piece 16, the memory alloy wire 22 can be contracted by exposing the fixing piece 16 or cooling it with cold air. The self-restoring force of the segment 20 or the contraction force of the memory alloy wire 22 can release the hook edge 21 from the hook ring 15, thereby making it easy to pull the fixing tube 19 out of the positioning hole 14, achieving convenient disassembly and replacement of the fixing piece 16.

[0030] Furthermore, there are two or more positioning holes 14, and the fixing cylinder 19 is provided in a one-to-one correspondence with the positioning holes 14. The one-to-one correspondence between two or more positioning holes 14 and the fixing cylinder 19 significantly increases the number of connection points between the fixing plate 16 and the bracket 1, making the connection force more evenly distributed and preventing loosening, deformation, or damage at a single connection point due to excessive stress. This greatly improves the stability and reliability of the fixing plate 16 after installation. In dynamic scenarios such as daily chewing and movement in the oral cavity, the corresponding connection at multiple points can effectively limit the displacement of the fixing plate 16, ensuring that the fixing plate 16 always maintains the preset position. This, in turn, ensures the precise limiting effect of the ligation limiting protrusion 17 on the fixing plate 16 on the ligation wire, preventing the ligation wire from shifting due to the displacement of the fixing plate 16, and ensuring the directional transmission of additional orthodontic force. At the same time, the cooperation between multiple sets of positioning holes 14 and the fixing cylinder 19 also makes the installation of the fixing plate 16 more stable, preventing skew during installation. Furthermore, when disassembling and replacing the fixing plate 16, the synchronous force at multiple points can reduce the wear of individual connection structures, extend the service life of the bracket 1 and the fixing plate 16, and further ensure the stable performance of the entire self-ligating bracket in the long-term orthodontic process.

[0031] Furthermore, the support body 1 is provided with a slider 2, which is L-shaped, and the self-locking sliding cover 7 is provided with a groove 8 that cooperates with the slider 2. The L-shaped slider 2 and the groove 8 are precisely matched, providing strong guidance and smooth sliding. This can stably constrain the movement trajectory of the self-locking sliding cover 7, improve the reliability of its switch screw groove 6, prevent deviation or loosening during sliding, and ensure stability in use.

[0032] Furthermore, the support body 1 is provided with a mounting hole 3, and a positioning rod 4 is provided in the mounting hole 3. The bottom of the self-locking sliding cover 7 is provided with a limiting groove 9, and the positioning rod 4 is inserted into the limiting groove 9. The positioning rod 4 and the limiting groove 9 are precisely matched, which can reliably limit the sliding stroke of the self-locking sliding cover 7, avoid overtravel displacement, and at the same time assist in guidance, ensuring the accurate and stable operation of its switch screw groove 6.

[0033] Furthermore, the upper surface of the self-locking sliding cover 7 and the upper surface of the tray 1 form a common upper surface, and an opening groove 5 is provided on the upper surface of the tray 1. The self-locking sliding cover 7 and the upper surface of the tray 1 form a flat common upper surface, which is seamless and has good coverage, effectively reducing food residue residue; the opening groove 5 on the tray 1 alone facilitates opening the sliding cover, taking into account both cleanliness and ease of use.

[0034] Furthermore, a ligation limiting interval 23 is formed between the same pair of ligation limiting protrusions 17. The ligation limiting interval 23 formed between the same pair of ligation limiting protrusions 17 can form a precise enclosure and constraint on the ligation wire, effectively preventing it from shifting or slipping during the correction process, and ensuring that the ligation position remains constant.

[0035] Furthermore, the ligation limiting protrusions 17 of the same pair have the same protrusion height, while the protrusion heights of different pairs of ligation limiting protrusions 17 are different. The ligation limiting protrusions 17 located on the same side of the central axis 13 of the sink 12 are arranged in descending order of height. The consistent height of the ligation limiting protrusions 17 of the same pair ensures that the width of the corresponding limiting interval is regular. The differentiated height settings of different pairs form a multi-level ligation limiting interval 23, which can accurately adapt to different specifications of ligation wires.

[0036] Furthermore, except for the ligation limiting protrusion 17 furthest from the central axis 13 of the sink 12, the other ligation limiting protrusions 17 have protruding sharp portions 18 on the top of the side furthest from the central axis 13 of the sink 12. The protruding sharp portions 18 allow for positioning of the ligation wire when it is located on top of these protrusions. For example, the ligation wire is positioned within the ligation limiting interval 23 between the outermost ligation limiting protrusion 17 and the pair of ligation limiting protrusions 17. Within this interval, the protruding sharp portions 18 of the ligation limiting protrusions 17 can abut against the ligation wire, thus providing auxiliary fixation and preventing displacement or slippage of the ligation wire within the interval. Combined with multi-level limiting intervals of different heights, this accurately adapts to the positioning requirements of ligation wires of different specifications while ensuring stable ligation force.

[0037] Furthermore, the ligation limiting protrusion 17 is configured as an elongated strip, and the top edge of the ligation limiting protrusion 17 is provided with an arc-shaped chamfer, which can achieve a good limiting effect on the ligation wire.

[0038] The above description of the embodiments is provided to facilitate understanding and use of the present invention by those skilled in the art. It is obvious to those skilled in the art that various modifications can be easily made to the embodiments, and the general principles described herein can be applied to other embodiments without creative effort. Therefore, the present invention is not limited to the above embodiments. Any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
