Description

Technical Field

[0001] This utility model relates to the field of dental orthodontics technology, specifically to a dental orthodontic bracket structure. Background Technology

[0002] Brackets are orthodontic appliances used in orthodontic treatment, primarily by orthodontists. Currently, various types of self-ligating brackets are widely used in clinical practice, greatly simplifying archwire locking for dentists. Self-ligating brackets have become a market trend in orthodontics, offering comprehensive specifications and increasingly becoming a mid-to-high-end product.

[0003] Self-ligating brackets typically consist of a mesh base for bonding, a bracket body located on the mesh base, locking tabs movably mounted on the bracket body, and a locking structure between the locking tabs and the bracket body support. Self-ligating brackets rely on the locking structure to hold the locking tabs in specific positions, particularly the closed position where the tabs enclose the archwire groove. In actual use, the archwire within the archwire groove exerts forces on the bracket body and locking tabs in various dimensions. Foreign objects during eating can affect the self-ligating brackets, and repeated opening and closing of the locking tabs during follow-up appointments can lead to problems such as loose locking, falling off, self-ligating failure, and plastic deformation of the locking mechanism under impact from foreign objects.

[0004] Although the market is constantly iterating on self-locking bracket structures, the above-mentioned problems still exist, so there is still considerable room for improvement. Utility Model Content

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a dental orthodontic bracket structure with a more stable self-ligating structure, so as to ensure that the orthodontic structure can be used stably for a long time.

[0006] The technical solution adopted by this utility model is: a dental orthodontic bracket structure, including a bracket body and a locking component; the top side of the bracket body is provided with a mounting platform for slidingly installing a locking plate, the top of the bracket body is provided with a stop position at one end corresponding to the mounting platform, and an archwire groove is provided between the bracket body and the mounting platform corresponding to the stop position; the locking component includes a solid rod and a hollow sleeve arranged on the mounting platform and inside and outside, the upper end of the locking component can slide and cooperate with a sliding groove provided on the bottom surface of the locking plate, and can engage and fix with locking grooves located at both ends of the sliding groove.

[0007] In this technical solution, the bracket structure is used in conjunction with the locking plate structure, allowing the locking plate structure to slide on the mounting platform for opening or closing the archwire slot. When the archwire slot is open, the matching archwire can be inserted into the slot for installation. The slidingly mounted locking plate is locked by a locking mechanism when the archwire slot is opened or closed. The locking mechanism structure allows the locking plate to slide normally and also fixes it when the archwire slot is opened or closed, ensuring that the locking plate remains in a stable locked state when the archwire slot is opened or closed. This prevents the locking plate from shaking during use and ensures the normal operation of the orthodontic appliance.

[0008] Preferably, the bottom of the tray is provided with a mesh bottom.

[0009] Preferably, the side of the bracket body corresponding to the stop position and opposite to the locking piece is provided with a clearance groove that penetrates the top of the bracket body.

[0010] Preferably, the mounting platform surface is provided with a pair of slide rails arranged perpendicular to the stop position, and the slide rails can be slidably adapted to the locking plate.

[0011] Preferably, the side of the bracket away from the mounting platform is provided with a traction hook.

[0012] Preferably, there is a gap between the hollow sleeve and the solid rod, and the hollow sleeve is elastic.

[0013] Preferably, the elastic deformation of the hollow sleeve when it is located in the groove is less than the gap between the hollow sleeve and the solid rod.

[0014] Preferably, the mounting platform surface is provided with at least one mounting hole for mounting a locking component.

[0015] The beneficial effects of this invention are as follows: This invention uses a bracket structure to work in conjunction with a locking mechanism. The locking element secures the locking plate when the archwire slot is opened or closed, maintaining a stable locked state and preventing the locking plate from wobbling during use, thus ensuring the normal operation of the orthodontic appliance. The locking element solves the problem of self-ligating failure due to long-term wear in existing technologies, and can be widely applied in the field of orthodontic appliances, possessing high practical value.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0027] like Figures 1 to 7As shown, a specific embodiment of this utility model provides a dental orthodontic bracket structure, including a bracket body 1 and a locking member 2; the top side of the bracket body 1 is provided with a mounting platform 12 for slidingly installing the locking plate, and the top of the bracket body 1 is provided with a stop position 13 corresponding to one end of the mounting platform 12, and an archwire groove 15 is provided between the bracket body 1 and the mounting platform 12 corresponding to the stop position 13; the locking member 2 includes a solid rod 22 and a hollow sleeve 21 arranged on the mounting platform 12 and arranged inside and outside, the upper end of the locking member 2 can slide and cooperate with the sliding groove 32 provided on the bottom surface of the locking plate 3, and can be engaged and fixed with the locking grooves 33 located at both ends of the sliding groove 32.

[0028] like Figures 1 to 7 As shown, through the above configuration, the bracket structure in this embodiment is used in conjunction with the corresponding locking plate 3 structure and archwire; the matching locking plate 3 is slidably mounted on the mounting platform 12 of the bracket body 1, and the archwire groove 15 is opened or closed by the sliding of the locking plate 3. When the archwire groove 15 is open, it is easier to insert and install the archwire; the slidably mounted locking plate 3 is locked by the locking member 2 when the archwire groove 15 is opened or closed; the bottom of the locking plate 3 has a sliding groove 32, and both ends of the sliding groove 21 also have locking grooves 33, so that the locking plate 3 can lock during the sliding process. The locking element 2 is able to slide and engage with the slide groove 32, and the locking element 2 can undergo elastic deformation and recover after sliding into the locking groove 33, so that the locking element 2 and the locking groove 33 are locked together. This allows the locking piece 3 to maintain a stable locked state when the bow wire groove 15 is opened or closed, and avoids the locking failure causing the locking piece 3 to shake. Usually, a pair of locking elements 2 need to be set on the mounting platform 12, and a pair of slide grooves 33 are arranged on the locking piece 3 accordingly, thus forming a double locking structure. The double positioning locking structure solves the problem of self-locking failure caused by the single locking structure in the prior art.

[0029] like Figure 3 , Figure 6 and Figure 7As shown, in this embodiment, the locking component 2 includes a solid rod 22 and a hollow sleeve 21 arranged internally and externally. There is a gap between the hollow sleeve 21 and the solid rod 22, and the hollow sleeve 21 is elastic, allowing it to undergo elastic deformation when located in the slide groove 32. The elastic deformation of the hollow sleeve 21 in the slide groove 32 is less than the gap between the hollow sleeve 21 and the solid rod 22. In other words, the locking component 2 is a semi-solid structure that can undergo elastic deformation, consisting of the solid rod 22 and the hollow sleeve 21. The gap between the hollow sleeve 21 and the solid rod 22 allows for smooth assembly of the two structures. Furthermore, this gap ensures that when the hollow rod is located in the slide groove 32, the part in contact with the slide groove 32 can undergo elastic deformation and automatically recover after it is engaged in the locking groove 33. This also adapts to the needs of different designs. The advantage of this design is that, after long-term use, when the hollow sleeve 21 is subjected to prolonged compression and eventually undergoes plastic deformation that cannot be restored, the solid rod 22 arranged inside the hollow sleeve 21, being a solid structure, cannot be compressed and deformed. Therefore, it can still lock with the locking groove 33, further ensuring the stability of its self-locking function. To ensure smooth sliding of the locking piece 3 and stability after locking, the sidewalls of the slide groove 32 are smoothly arranged, and the transition area between the slide groove 32 and the locking groove 33 is rougher, which is beneficial for maintaining a stable self-locking state of the locking piece 3.

[0030] like Figure 7 As shown, since the two sets of locking elements 2 are independent of each other, even if a corresponding locking element 2 and the slide groove 32 wear out due to long-term engagement, it will not cause the failure of the entire locking structure. Typically, the hollow sleeve 21 has a circular cross-sectional shape, and the wall thickness of the hollow sleeve 21 is 0.04mm to 0.1mm. The gap D1 between the solid rod 22 and the hollow sleeve 21 ranges from 0.02mm to 0.05mm. In terms of specific materials, the solid rod 22 and the hollow sleeve 21 are made of elastic metals such as nickel-titanium or stainless steel.

[0031] like Figure 3 As shown, regarding the installation method of the locking components 2, since both locking components 2 need to be installed on the mounting platform 12, the surface of the mounting platform 12 is provided with spaced-apart mounting holes 121 for installing the locking components 2. The arrangement of the two mounting holes is as follows: Figure 4 As shown, the distance D1 between the two mounting holes 121 on the mounting platform 12 parallel to the slide rail is 0.5mm to 1mm, and the distance D2 between the two mounting holes on the mounting platform 1 in the direction perpendicular to the slide rail is 0mm to 1mm.

[0032] like Figure 1 As shown, in this embodiment, the mounting hole is completely through the bracket body 1, and the end of the mounting hole away from the locking piece 3 can be sealed by welding, bonding or other methods.

[0033] like Figure 1 and Figure 2As shown, in practical applications, the bottom of the bracket body 1 is provided with a mesh base 4. The mesh base 4 can be used to stably install the entire bracket body 1 structure. The connection relationship between the bracket body 1 and the mesh base 4 can be adjusted according to the needs of the orthodontic plan and orthodontic data. In some applications, the side of the bracket body 1 away from the mounting platform 12 is provided with a traction hook 16 to assist orthodontic treatment.

[0034] As mentioned earlier, when the locking piece 3 of the bracket structure closes the archwire groove 15, the locking member 2 needs to be engaged with the locking groove 33 to achieve self-locking fixation of the locking piece 3. In order to open the locking piece 3 and remove the archwire after use, this embodiment provides an avoidance groove 14 that penetrates the top of the bracket body 1 on the side opposite to the locking piece 3 at the corresponding stop position 13 of the bracket body 1. Figure 3 As shown, the clearance groove 14 allows a groove structure to be formed between the end of the locking plate 3 and the stop position 13. This groove structure is arranged on the side of the stop position 13 and does not affect the sealing of the bow wire groove 15 by the locking plate 3. When the locking plate 3 needs to be opened after sealing the bow wire groove 15, it can be opened with the help of an external tool. The specific opening method of the locking plate 3 is to use a one-piece opening tool or a customized spring-type tool, insert the tool into the clearance groove 14 and rotate it. When the locking plate 3 is subjected to a horizontal pushing force, the locking member 2 can be disengaged from the locking groove 33, so that the locking plate 3 can be slid smoothly and the bow wire groove 15 can be opened.

[0035] like Figure 3 As shown, to ensure that the locking piece 3 can slide stably along the slide groove 32, this embodiment has a pair of slide rails 11 arranged perpendicular to the stop position 13 on the surface of the mounting platform 12, and a slide rail 31 at the bottom of the locking piece 3 that slides in cooperation with the slide rails 11. In this way, the locking piece 3 and the mounting platform 12 form a sliding cooperation through the double rail structure. When the locking piece 3 slides between the open and closed positions of the bow wire groove 15, the stable cooperation between the two slide rails 11 and the slide rail 31 ensures the stability and accuracy of the sliding of the locking piece 3. The cooperation between the slide rails 11 and the slide rail 31 is an anti-disengagement structure. The double slide rail structure and the double locking structure ensure that the locking piece 3 only has the degree of freedom along the sliding direction of the slide rails 11, preventing the locking piece 3 from rotating when sliding, and further ensuring the motion accuracy and stability of the self-locking system.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
