Description

Technical Field

[0001] The present invention relates to the field of oral orthodontics, and in particular to an arch control device for oral orthodontics. Background Art

[0002] Orthodontic treatment involves applying a continuous corrective force to the teeth through orthodontic archwires, causing them to shift in the desired direction, thereby achieving an orthodontic effect. During clinical practice, orthodontists bond preformed orthodontic archwires to the patient's teeth, using the archwire's ability to deform and reposition, to pull the teeth to the target position. Using an inappropriately shaped or poorly controlled archwire for correction may result in poor results or in the inability to maintain the corrective effect.

[0003] With the application of digital technology in the dental industry, more and more patients choose to use personalized lingual products, namely personalized lingual brackets and personalized lingual archwires. According to feedback from clinicians, when existing lingual brackets are used in conjunction with orthodontic archwires for correction, because orthodontic archwires generally use ribbon bows, ribbon bows have weak control over the horizontal teeth, and the teeth are prone to lingual tilt (existing orthodontic archwires generally include ribbon bows and horizontal bows, both of which have the problem of weak horizontal control over the teeth, but the control of the horizontal bow is weaker than that of the ribbon bow). The archwire is bonded to the lingual side, and the force-bearing surface of the teeth is on the lingual side. Therefore, the archwire is force-applied on the lingual side. The existing archwire has insufficient control of its own, and the correction effect is poor, which will cause the teeth to easily tilt lingually. If the archwire cannot be adjusted to the appropriate arch shape, it will have a negative impact on the therapeutic effect. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide an arch control device for oral orthodontics, which can solve the problem that the existing orthodontic arch wire has insufficient control force, thereby causing the teeth to be easily lingually tilted.

[0005] The present invention is achieved through the following technical solutions:

DETAILED DESCRIPTION

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0040] In the description of the present invention, it should be understood that the terms "center", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0042] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and may encompass internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0043] The present invention discloses an arch control device for orthodontics, see Figure 1-Figure 2 The archwire 10 includes an archwire 10, a control member 20, and a clamping mechanism 30. The archwire 10 can be a ribbon arch or a horizontal archwire. The control member 20 is used to enhance the control force of the archwire 10 on the teeth. The clamping mechanism 30 connects the archwire 10 and the control member 20. The control member 20 is secured to the inner or outer sides of the archwire 10 via a clamping mechanism 30 at each end. The control member 20 is an elastic member with a spring force. The spring force released by the control member 20 can control the archwire 10 to expand, retract, or maintain its shape. Furthermore, the control member 20 also increases the torque on the teeth.

[0044] Specifically, the size, width, and thickness of the control member 20 are designed based on the patient's correctional needs. The size and thickness of the control member 20 can adjust the force of arch expansion: if the width of the control member 20 is large, the control force released causes the arch wire 10 to expand outward, achieving an arch expansion effect; if the width of the control member 20 is small, the control force released causes the arch wire 10 to contract inward, achieving an arch contraction effect; if the width of the control member 20 is appropriate, the control force released prevents the arch wire 10 from deforming outward or inward, achieving an arch maintenance effect.

[0045] By applying a control force to the orthodontic arch wire 10 through the control member 20, the control force of the orthodontic arch wire 10 on the teeth is enhanced, and the arch wire 10 is always adjusted to the appropriate arch shape, which can achieve arch expansion, arch retraction, or arch maintenance. This solves the problem that the current band arch has insufficient control force on the horizontal teeth, which causes the teeth to be prone to lingual tilt, and effectively improves the correction effect. According to the specific situation of the patient, multiple pairs of control members 20 can be personalized and replaced with different control members 20 at different stages of correction. This meets the needs of different patients for arch expansion, arch retraction, and arch maintenance at different stages of correction, which has important clinical significance.

[0046] The control member 20 may preferably be made of nickel-titanium metal material, stainless steel material, elastomer material, etc., but is not limited thereto. All other known elastic materials should be within the scope of protection of the present invention.

[0047] In order to achieve different control effects by the control force exerted by the control member 20 on the arch wire 10, preferably, refer to Figure 3-Figure 7 The control member 20 may also be provided with a plurality of curved structures 21. The curved structures 21 may change the control force of the control member 20, for example, making the control force of the control member 20 softer. Further preferably, the types of curved structures 21 include, but are not limited to, open vertical curves, omega curves, open vertical curves with loops, small loop curves, and other curved structures 21 known in the orthodontic field.

[0048] Preferably, see Figure 8 The control member 20 may also be provided with an expander 22, an orthodontic sleeve and other accessories for use in conjunction with the control member 20 to achieve a better correction effect.

[0049] The clamping mechanism 30 includes a first connecting end 31 and a second connecting end 32. The first connecting end 31 is fixed to the end of the control member 20, and the second connecting end 32 is fixed to the inner side or the outer side of the arch wire 10. There are many embodiments of the connection method of the clamping mechanism 30.

[0050] Example 1: See Figure 9-10 The clamping mechanism 30 utilizes an undercut structure for connection. Both the first and second connecting ends 31 and 32 are provided with a slot 311. The slot 311 has an opening for receiving the arch wire 10, and the slot 311 includes a plurality of serrations 312 for securing the arch wire 10. During use, the control member 20 and the arch wire 10 are snapped into the slot 311 through the bayonet. The serrations 312 within the slot 311 restrict movement of the control member 20 and the arch wire 10, achieving a secure connection.

[0051] Example 2: See Figure 11-12 The clamping mechanism 30 is connected by a threaded connection. A threaded structure 313 is provided in each of the first connecting end 31 and the second connecting end 32. The end of the control member 20 and the side of the arch wire 10 are each provided with a matching threaded structure 313. The clamping mechanism 30 is threadedly connected to the control member 20 and the arch wire 10, respectively.

[0052] Example 3: The clamping mechanism 30 is fixed by bolts 314, and the first connection end 31 and the second connection end 32 are fixedly connected by bolts 314. Specifically, see Figure 13 The first connecting end 31 and the second connecting end 32 are both provided with screw holes. After the control member 20 and the arch wire 10 are respectively installed in the clamping mechanism 30, the bolts 314 are screwed into the screw holes. The bolts 314 press the control member 20 and the arch wire 10 downward to restrict the movement of the control member 20 and the arch wire 10, thereby achieving a stable connection. Alternatively, refer to Figure 14 The first connecting end 31 and the second connecting end 32 are provided with a slot 311 , and the openings of the slot 311 of the first connecting end 31 and the second connecting end 32 are locked by a bolt 314 .

[0053] Embodiment 3: The clamping mechanism 30 is fixed by welding. The first connecting end 31 is fixed by welding to the control member 20 , and the second connecting end 32 is fixed by welding to the archwire 10 .

[0054] Embodiment 4: The clamping mechanism 30 is fixed by bonding. The first connecting end 31 is bonded and fixed to the control member 20 , and the second connecting end 32 is bonded and fixed to the arch wire 10 .

[0055] Of course, the connection between the clamping mechanism 30 and the control member 20 and the arch wire 10 may also adopt other fixing methods known in the art, and all should be within the scope of protection of the present invention.

[0056] In the present invention, the control member 20 can be used on both the labial and lingual sides. According to different usage positions, the control member 20 can be divided into several types: a lingual maxillary control member 23, a lingual mandibular control member 24, and a labial control member 25.

[0057] When the control member 20 is applied to the lingual arch wire 10: Figure 15 The control member 20 includes a lingual maxillary control member 23; the two sections of the lingual maxillary control member 23 are connected to the inner sides of the arch wire 10, and the lingual maxillary control member 23 is located at the upper jaw position near the oral cavity. Figure 16 The control member 20 also includes a lingual mandibular control member 24, and both ends of the lingual mandibular control member 24 are connected to the two inner sides of the arch wire 10; since tongue space must be reserved at the lingual mandibular position, otherwise the positions of the control member 20 and the tongue will interfere with each other, the lingual mandibular control member 24 is bent along the labial direction and is located in front of the tongue near the teeth.

[0058] When the control member 20 is applied to the labial arch wire 10: Figure 17 The control member 20 includes a labial control member 25, which is arranged on the labial side of the arch wire 10 and bent along the tooth direction so that the control member 20 is not easily interfered with the inner side of the lip; the two ends of the labial control member 25 are connected to the two outer sides of the arch wire 10 at this time.

[0059] Clinically, multiple pairs of the control devices can be designed according to correction needs. Doctors can adjust and replace them in time according to the stage correction needs. There is no need for on-site bending, and the operation is convenient.

[0060] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
