Description

Technical Field

[0001] This invention relates to the field of orthodontic instruments, specifically to an orthodontic bracket installation system and its components, particularly an ultra-thin ribbon bracket and its dedicated positioning forceps. Background Technology

[0002] In orthodontic treatment, bracket bonding is a crucial step. In recent years, to improve patient comfort, ultra-thin strap brackets (e.g., the ultra-thin, perforated strap bracket standard bracket disclosed in patent publication number CN222150192U) have become a development trend. These brackets achieve ultra-thinness by drastically reducing the thickness of the substrate, but this also brings a serious clinical problem overlooked by existing technologies: the small and smooth surface area of ​​the mesial and distal sides of the substrate makes it difficult for dentists to form an effective gripping point between the forceps and the bracket sides when performing direct bonding with conventional forceps, easily leading to slippage and detachment. Due to the small size of the brackets, they are difficult to locate, severely impacting diagnostic and treatment efficiency and the patient's experience.

[0003] Existing technologies include some improved dental forceps or positioning devices. For example, patent publication number CN215937737U discloses forceps that assist in bonding by setting an intermediate pressure bar and an elastic telescoping mechanism; patent publication numbers CN111772838A and CN214073673U disclose positioning devices for indirect bonding, which fix the bracket to a disposable positioning device through interference fit or other methods. However, these improvements in the prior art do not involve synergistic improvements to the structure of reusable forceps and the bracket itself that needs to be permanently bonded. They cannot solve the fundamental gripping problem caused by the structural characteristics of ultra-thin brackets during direct manual operation.

[0004] Therefore, there is an urgent need in this field for an innovative and systematic solution that can collaboratively innovate from two dimensions: the "object being held" (the tray) and the "holding tool" (tweezers), to fundamentally solve the problem of holding stability of ultra-thin trays in the direct bonding process. Summary of the Invention

[0005] The primary objective of this invention is to provide an orthodontic bracket, particularly an ultra-thin orthodontic bracket, which, through improvements to its substrate structure, is easily and stably clamped during direct bonding operations.

[0006] Another objective of this invention is to provide a positioning forceps that is compatible with the orthodontic bracket, wherein the clamping part is structurally designed to precisely prevent dislodgement from the improved orthodontic bracket structure.

[0007] The ultimate goal of this invention is to provide an orthodontic bracket installation system that includes the above-mentioned orthodontic brackets and positioning forceps, thereby completely solving the problem of unstable direct clamping in clinical practice through the synergistic effect of the two.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides an orthodontic bracket, comprising a bracket body, the bracket body including a base plate, a substrate, and bracket wings disposed on the substrate. Its innovation lies in that: anti-dislodgement clamping structures are provided on the mesial and distal surfaces of the substrate, the structures being configured to complementarily cooperate with the clamping portion of a clamping tool to improve clamping stability.

[0009] Preferably, the anti-detachment clamping structure can be a wedge-shaped inner inclined surface (with an inner inclination angle of 1°-30°) for inclined clamping, and / or an anti-detachment clamping groove for positioning and anti-detachment. The inner inclination angle of the wedge-shaped inner inclined surface is preferably 1°-30°. The anti-detachment clamping groove is preferably an arc-shaped groove parallel to the base plate.

[0010] In a second aspect, the present invention provides positioning tweezers for gripping the aforementioned tray. The positioning tweezers include a tweezers body and two opposing gripping arms. Its innovation lies in that the gripping portion at the front end of each gripping arm is configured to complement and cooperate with an anti-detachment gripping structure on the tray base.

[0011] Preferably, the clamping part is an inwardly inclined clamping part, forming a clamping end that is narrower at the front and wider at the back, and its inward inclination angle is adapted to the wedge-shaped inwardly inclined surface of the bracket. More preferably, the inner side of the clamping part is also provided with an engaging structure (such as a protrusion) for engaging with the anti-detachment clamping groove of the bracket.

[0012] In a third aspect, the present invention provides an orthodontic bracket installation system. The system includes the aforementioned orthodontic bracket and the positioning forceps of the present invention. The anti-dislodgement clamping structure on the orthodontic bracket is adapted to the clamping portion of the forceps, working together to achieve stable clamping.

[0013] When the aforementioned technical solution is applied to the ultrathin strip arch support groove, the specific manifestations are as follows: An ultra-thin strip-shaped arch support includes a support body, which includes a base plate, a substrate, and support wings disposed on the substrate. Its innovation lies in that the near, far, and middle sides of the substrate are provided with anti-dislodgement clamping structures that facilitate tweezers to hold the support.

[0014] As a further improvement of the present invention, the anti-detachment clamping structure can be a wedge-shaped inward inclined surface that slopes inward from the top (away from the bottom plate) of the bracket base towards its bottom (near the bottom plate), with an inward inclination angle of any angle between 1° and 30°, so that the near and far sides of the base form a wedge shape that is wider at the top and narrower at the bottom.

[0015] Using a wedge-shaped inward inclined surface as an advantageous clamping structure in the anti-dislodgement clamping structure, when doctors use tweezers to clamp the ultra-thin bracket with the wedge-shaped inward inclined surface for bonding, the tweezers and the wedge-shaped inward inclined surface on the proximal and distal sides of the bracket base form an effective clamping, which is stable and not easy to slip off or fall off.

[0016] Of course, in order to better adapt to this bracket with a wedge-shaped inwardly inclined surface, we have also designed a positioning tweezer with a clamping end that is narrower at the front and wider at the back, which is more compatible with it. The inwardly inclined angle of the inwardly inclined clamping part of the positioning tweezer is slightly greater than the inwardly inclined angle of the wedge-shaped inwardly inclined surface on the proximal and distal sides of the ultra-thin strip arch bracket.

[0017] Furthermore, an anti-detachment clamping groove can be provided at the bottom of the wedge-shaped inner inclined surface near the base plate of the tray, and parallel to the base plate. This anti-detachment clamping groove is preferably an arc-shaped groove. This anti-detachment clamping groove can cooperate with the protrusion on the inner side of the clamping end of the positioning tweezers to form a more effective clamping point, ensuring stable clamping and preventing slippage and drop.

[0018] Alternatively, the anti-detachment clamping structure can be independently configured as an anti-detachment clamping groove, located on the near and far sides of the substrate close to the bottom plate and parallel to the bottom plate. Similarly, this anti-detachment clamping groove is preferably an arc-shaped groove. This anti-detachment clamping groove can cooperate with the protrusion on the inner side of the clamping end of the positioning tweezers to form a more effective clamping point, ensuring stable clamping and preventing slippage and drop.

[0019] Another key aspect of this invention is the simultaneous provision of a positioning tweezers for use with the aforementioned ultra-thin ribbon arch support. This positioning tweezers includes a tweezers body with two opposing clamping arms. Its innovation lies in the fact that the front clamping portion of each clamping arm is an inwardly inclined clamping portion, and the front clamping portions of the two opposing clamping arms together form a clamping end that is narrower at the front and wider at the back, with its inward inclination angle adapted to the wedge-shaped inwardly inclined surface of the support. Furthermore, the inner side of the clamping end is also provided with a protrusion for engaging with the anti-dislodgement clamping groove of the support.

[0020] The protrusion is preferably an arc-shaped protrusion. The inward tilt angle of the inward tilting clamping part is 1°-30°, and the inward tilt angle of the inward tilting clamping part of the positioning tweezers is slightly larger than the inward tilt angle of the wedge-shaped inward tilting surface on the proximal and distal sides of the ultra-thin strip-shaped arch support. The shape of the clamping part of the positioning tweezers is adapted to the anti-dislodgement clamping structure on the support base, which can achieve stable and reliable clamping.

[0021] The inventive concept of this invention is not simply an isolated improvement to the tray or tweezers, but rather a creatively proposed integrated "product-tool" system solution. We recognize that to fundamentally solve the clamping challenge of ultra-thin trays, collaborative innovation is necessary from two dimensions: the "object being clamped" (the tray) and the "clamping tool" (tweezers). On the bracket, we have deviated from the norm by designing a specific anti-detachment structure (wedge-shaped surface, groove or combination thereof) on the side of its ultra-thin substrate, providing a reliable "point of force" for clamping.

[0022] Instead of relying on general-purpose tweezers, we have customized a clamping end that is precisely matched to it. The structure of "inner inclined surface + protrusion" complements the "wedge-shaped surface + groove" on the bracket.

[0023] This matching design allows the tray and tweezers to fit together like a "key and lock," thus achieving dual stable clamping.

[0024] Compared with the prior art, the present invention has the following significant advantages: Systematic innovation to fundamentally solve the problem: This invention creatively proposes a system solution with a "slot-tweezers" collaborative design. Starting from the source of the problem, it achieves a fundamental breakthrough in the stable clamping of ultra-thin slots in direct bonding operations through structural complementarity.

[0025] Synergistic effect for dual stability: The wedge-shaped inner inclined surface for inclined clamping cooperates with the clamping end that is narrower at the front and wider at the back. Utilizing the self-locking principle of the inclined surface, it effectively guides and stabilizes the clamping force, preventing slippage. The positioning structure (groove) cooperates with the engaging structure (protrusion) to form a mechanical interlock, further preventing slippage. The combination of these two elements produces a synergistic effect of "dual stable clamping," whose stability and reliability far surpass those of a single improvement.

[0026] Improving clinical efficacy: This invention greatly reduces the slippage rate of orthodontic brackets during direct bonding operations, reduces operation time, alleviates the burden on doctors, and improves the overall efficiency and quality of orthodontic treatment.

[0027] Easy to promote: All improvements are based on the product's main structure, requiring no complex additional parts, making the process simple, cost controllable, and highly valuable for market promotion. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this invention. The embodiments and directional terms described below with reference to the accompanying drawings are exemplary and intended to explain this invention, and should not be construed as limiting this invention. Example 1

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the ultra-thin strip-shaped arch support includes a base plate 1, a substrate 2, and support wings 3 disposed on the substrate 2. The substrate 2 has anti-detachment clamping grooves 4 (anti-detachment clamping structures) on its proximal and distal sides for easy gripping by tweezers. In this embodiment, the anti-detachment clamping grooves 4 are arc-shaped grooves, located on the proximal and distal sides of the substrate 2 near the base plate 1 and parallel to the base plate 1. Using the anti-detachment clamping grooves 4 as an advantageous clamping structure, these grooves can cooperate with the protrusions 13 on the inner side of the clamping end of the positioning tweezers 10 to form a more effective clamping point, ensuring stable clamping and preventing slippage and drop.

[0031] like Figure 4As shown, the tweezers 10 are used in conjunction with the aforementioned ultra-thin ribbon arch support groove. The tweezers 10 include two opposing clamping arms 11, the front end of which is an inwardly inclined clamping portion 12. The inwardly inclined clamping portions 12 at the front ends of the two opposing clamping arms 11 form a clamping end that is narrower at the front and wider at the back. A protrusion 13 is also provided on the inner side of this clamping end (the inwardly inclined clamping portions 12 at the front ends of the two opposing clamping arms 11). In this embodiment, the protrusion is arc-shaped, and its size is slightly smaller than the ultra-thin ribbon arch support groove 4 to facilitate automatic alignment.

[0032] The inward tilt angle of the inward tilting clamping part 12 is any angle from 1° to 15°. In this embodiment, 8° is selected. The inward tilt angle of the inward tilting clamping part 12 of the tweezers 10 is slightly larger than the inward tilt angle of the wedge-shaped inward tilting surface on the proximal and distal sides of the ultra-thin strip arch support groove.

[0033] The shape of the inwardly inclined clamping part 12 and its protrusion 13 of the tweezers 10 are adapted to the anti-disengagement clamping groove 4 (anti-disengagement clamping structure) on the bracket base, so as to achieve stable and reliable clamping.

[0034] In use, the doctor uses the inwardly inclined clamping part 12 of the positioning forceps 10 to clamp the mesial and distal sides of the bracket base 2. The inwardly inclined surface of the inwardly inclined clamping part 12 fits against the mesial and distal sides of the ultra-thin strip arch bracket. At the same time, the arc-shaped protrusion 13 of the positioning forceps 10 is inserted into the anti-dislodgement clamping groove 4 of the bracket to form an effective engagement and prevent slippage. The inwardly inclined surface also provides auxiliary clamping force to achieve stable clamping. Example 2

[0035] like Figure 5 As shown, the ultra-thin strip arch support includes a base plate 1, a base body 2, and support wings 3 disposed on the base body 2. The near and far sides of the base body 2 are provided with wedge-shaped inward inclined surfaces 5 (anti-detachment clamping structure) for easy gripping by tweezers. The wedge-shaped inward inclined surfaces 5 are inclined inward from the top (away from the base plate) of the support base body 2 to its bottom (close to the base plate), and the inward inclination angle is any angle within the range of 1°-15°. In this embodiment, the inward inclination angle is 5°, so that the near and far sides of the base body form a wedge shape that is wider at the top and narrower at the bottom.

[0036] like Figure 5 and Figure 6 As shown, in order to better adapt to this bracket with a wedge-shaped inward inclined surface, we have also designed a positioning tweezer 10 with a clamping end that is narrow at the front and wide at the back, which is more adaptable to it. The inward inclination angle of the inward inclined clamping part of the positioning tweezer 10 is preferably 8°, which is slightly larger than the inward inclination angle of the wedge-shaped inward inclined surface on the proximal and distal sides of the ultra-thin strip arch bracket, which is 5°.

[0037] Using a wedge-shaped inward inclined surface as an advantageous clamping structure in the anti-detachment clamping structure, when the dentist uses tweezers 10 to clamp the ultra-thin bracket with the wedge-shaped inward inclined surface for bonding, the clamping end of the tweezers, which is narrow at the front and wide at the back, fits tightly with the wedge-shaped surface of the bracket, which is wide at the top and narrow at the bottom. The self-locking principle of the inclined surface is used to achieve stable anti-detachment clamping, effectively preventing the bracket from slipping and falling off, and making it easy to accurately bond the bracket to the tooth surface. Example 3

[0038] Further improvements were made based on the above embodiments 1 and 2. For example... Figure 7 As shown, in this embodiment, the bracket base 2 is provided with wedge-shaped inward inclined surfaces 5 and anti-dislodgement clamping grooves 4 on both sides for inclined clamping. Taking the ultra-thin strip bow bracket as an example, specifically, the ultra-thin strip bow bracket includes a base plate 1, a base 2, and a bracket wing 3. The near and far sides of the base 2 are provided with wedge-shaped inward inclined surfaces 5, which slope inward from the upper part of the base to the lower part, with an inclination angle of 5° (preferably selected within the range of 1°-15°). This wedge-shaped inward inclined surface 5 can cooperate with the front-narrow and rear-wide clamping end of the positioning tweezers 10.

[0039] like Figure 8 As shown, the near and far sides of the substrate 2 not only have wedge-shaped inwardly inclined surfaces 5, but also an arc-shaped anti-detachment clamping groove 4 at its bottom near the base plate 1, parallel to the base plate 1. This anti-detachment clamping groove 4 can cooperate with the arc-shaped protrusion 13 on the inner side of the clamping end of the positioning tweezers 10 to form a more effective clamping point, ensuring stable clamping and preventing slippage and drop. Positioning tweezers 10 (as shown) Figure 8 As shown, it includes two opposing clamping arms 11, the front clamping part of which is an inwardly inclined clamping part 12 with an inward inclination angle of 8°, forming a structure that is narrow at the front and wide at the back. The inner side of the inwardly inclined clamping part 12 is provided with an arc-shaped protrusion 13, which is slightly smaller than the anti-detachment clamping groove 4 on the bracket, so as to facilitate automatic alignment.

[0040] like Figure 8 As shown, during use, the dentist uses the inwardly inclined clamping part 12 of the positioning forceps 10 to clamp the mesial and distal sides of the bracket base 2. The inwardly inclined clamping part 12 of the positioning forceps 10 fits against the wedge-shaped inwardly inclined surface 5, achieving self-locking and anti-detachment on the inclined surface. At the same time, its inner protrusion 13 engages in the anti-detachment clamping groove 4, forming a mechanical interlocking anti-detachment mechanism. This design achieves a double guarantee of "inclined self-locking + groove locking," achieving the best dual stable clamping effect, greatly improving the reliability of clamping and the efficiency of clinical operation, and making it easier for the dentist to accurately attach the bracket to the tooth surface.

[0041] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
