Description

Technical Field

[0001] The present invention relates to the technical field of orthodontics, in particular to orthodontic devices, and more specifically, to a single-arm torsion tooth torque orthodontic auxiliary arch device. Background Art

[0002] Torque control is particularly important for the orthodontic treatment of rotated teeth. Existing methods for enhancing torque mainly increase the torque moment by increasing the bend of the Third Order Bend and generating "force" through the deformation of the rectangular arch wire. Related methods for enhancing torque also include using a portal auxiliary arch to correct the torque of a single-arm tooth.

[0003] In the process of implementing the concept of the present invention, the inventors found that at least the following problems exist in the related art: The deformation of the rectangular arch wire of the Third Order Bend is limited. Due to the small force arm, the increased torque force is also limited. Moreover, there is also the problem of "clearance angle" (that is, the main arch wire groove is wider than the arch wire, and the bent rotation angle cannot be fully expressed in torque adjustment), and the ideal effect of single-tooth torque control cannot be obtained; and bending the Third Order Bend takes more chairside time and requires a higher operating level of the doctor, which is time-consuming and laborious in clinical practice. Using a portal auxiliary arch to correct the torque of a single-arm tooth can obtain limited torque force, and each time the torque force is adjusted, the main arch wire needs to be disassembled and the auxiliary arch needs to be further bent. Excessive adjustment times are likely to cause problems such as metal fatigue, wire breakage, and fracture at the welded joint of the portal auxiliary arch.

[0004] Therefore, those skilled in the art urgently need to develop a more convenient, efficient, and time-saving single-tooth torque adjustment device to achieve the purpose of improving the chairside diagnosis and treatment efficiency. Summary of the Invention

[0005] In view of this, the technical problem to be solved by the present invention is to provide a single-arm torsion tooth torque orthodontic auxiliary arch device, which solves the problems of limited increased torque force and more chairside time in the prior art.

[0006] To solve the above technical problem, a specific embodiment of the present invention provides a single-arm torsion tooth torque orthodontic auxiliary arch device, including: at least one fixing member movably arranged on the main arch wire; a connecting rod arranged on the fixing member; and an elastic wire arranged on the connecting rod, wherein the free end of the elastic wire abuts against the labial surface of the rotated tooth to apply a torque force to the rotated tooth.

[0007] Optionally, the single-arm torsion tooth torque orthodontic auxiliary arch device further includes: an elastic patch arranged at the free end of the elastic wire for directly contacting the labial surface of the rotated tooth to apply a torque force to the rotated tooth.

[0008] Optionally, the cross-section of the elastic wire is circular or square.

[0009] Optionally, the portion of the free end of the elastic steel wire that contacts the labial surface of the twisted tooth is wrapped with resin.

[0010] Optionally, the free end of the elastic wire is in line contact or surface contact with the labial surface of the twisted tooth.

[0011] Optionally, the free end of the elastic wire abuts against the labial surface of the twisted tooth at a position 1 mm above the bracket or 1 mm below the bracket.

[0012] Optionally, the fixing member includes: at least one hook clamp for movably setting the connecting rod on the main arch wire.

[0013] Optionally, the hook forceps include: an upper side clamp, which is arranged on the connecting rod, wherein the upper side clamp includes a first open end and a first rotating end, and the first rotating end has a first protrusion away from the first open end; a hinge, which is arranged on the first rotating end; a lower side clamp, which is rotatably connected to the upper side clamp through the hinge, wherein the lower side clamp includes a second open end and a second rotating end, and the second rotating end has a second protrusion away from the second open end; and an elastic member, which is arranged between the first protrusion and the second protrusion, wherein when an external force overcomes the elastic force of the elastic member, the first protrusion and the second protrusion approach each other, the first open end and the second open end move away from each other, the upper side clamp and the lower side clamp clamp the main arch wire, and when the external force disappears, the upper side clamp and the lower side clamp clamp the main arch wire under the action of the elastic force of the elastic member.

[0014] Optionally, the shape of the elastic steel wire includes at least one of a folded shape, a spiral shape, a butterfly shape, an inverted L shape, a vertical square wave shape, a vertical arch shape, an inverted left-fall shape, a square wave shape and a vertical sawtooth shape.

[0015] Optionally, when the elastic steel wire is in a folded shape, the elastic steel wire has 3 to 6 steel wire folded segments; when the elastic steel wire is in a spiral shape, the elastic steel wire has 3 to 5 turns of steel wire.

[0016] According to the above-mentioned embodiment of the present invention, one end of the elastic steel wire is pressed against the tooth surface that needs to be adjusted, and torque force is applied to the tooth through deformation of the steel wire, so as to correct the twisted tooth. This can at least partially solve the problem of limited torque force increase and more chairside time in the related technology, and thus achieve the technical effect of improving the efficiency of chairside diagnosis and treatment and increasing torque force.

[0054] Torque is the labiolingual torque twist formed on a rectangular arch wire to generate a torque force for adjusting the angle of teeth. In related technologies, only by bending the wire and then inserting the wire into the bracket with a rectangular slot can the entire row of teeth be rotated to align the teeth. Now, in many new brackets, this rotation angle is preset to the thickness and slope of the bracket, which can save the time of bending the wire and reduce the chair-side time. In related technologies, for a single labially inclined tooth or lingually inclined tooth, a third-order rectangular arch wire or a door-shaped auxiliary arch can be used for correction. However, for the correction of a single rotated tooth, the third-order rectangular arch wire or the door-shaped auxiliary arch is powerless. That is, although the orthodontic effect is a bit poor, the third-order rectangular arch wire or the door-shaped auxiliary arch can correct a single labially inclined tooth or lingually inclined tooth, but the third-order rectangular arch wire or the door-shaped auxiliary arch cannot orthodontically correct a single rotated tooth. A rotated tooth means that the tooth has no problem of labial inclination or lingual inclination, but it has rotated in place and needs to be rotated in the opposite direction in place for angle orthodontics.

[0055] Figure 1 FIG. 4 is a first structural schematic diagram of a single-arm rotated tooth torque orthodontic auxiliary arch device provided by a specific embodiment of the present invention.

[0056] In an embodiment of the present invention, as Figure 1 shown, the single-arm rotated tooth torque orthodontic auxiliary arch device may include: at least one fixing member 1, a connecting rod 2, and an elastic wire 3.

[0057] Specifically, at least one fixing member 1 is movably arranged on the main arch wire W; the connecting rod 2 is arranged on the fixing member 1; the elastic wire 3 is arranged on the connecting rod 2, wherein the free end of the elastic wire 3 abuts against the labial surface of the rotated tooth to apply a torque force to the rotated tooth.

[0058] In an embodiment of the present invention, the force application angle, thickness, hardness, material, etc. of the elastic wire 3 all affect the magnitude and direction of the torque force applied to the rotated tooth. Specifically, the cross-section of the elastic wire 3 can be circular, and the diameter of the elastic wire 3 can be, for example, 0.3048 mm (i.e., 0.012 inches), 0.3556 mm (i.e., 0.014 inches), or 0.4064 mm (i.e., 0.016 inches). The larger the diameter of the elastic wire 3, the greater the torque force applied to the rotated tooth, and the more significant the force applied to the rotated tooth; the smaller the diameter of the elastic wire 3, the smaller the torque force applied to the rotated tooth, and the less significant the force applied to the rotated tooth.

[0059] In the embodiments of the present invention, a torque force is applied to the rotated tooth by using the elastic wire 3, the connecting rod 2 and the fixing member 1. By adjusting the shape of the elastic wire 3 and the connecting rod 2, and rotating the elastic wire 3 to adjust the magnitude and position of the applied force, the rotation angle of a single rotated tooth can be finely adjusted, solving the problem in the prior art that the angle of a single rotated tooth cannot be adjusted, and making orthodontic diagnosis and treatment more efficient. Applying a torque force to the rotated tooth by using the elastic wire 3, the connecting rod 2 and the fixing member 1 occupies less space, and the force application point, the magnitude and direction of the applied force can be set more freely, with convenient operation. After the patient wears it, the foreign body sensation is small, and the patient experience is high.

[0060] Figure 2 It is a second structural schematic diagram of a single-arm rotated tooth torque orthodontic auxiliary arch device provided by a specific embodiment of the present invention.

[0061] In the embodiments of the present invention, as Figure 2 shown, the single-arm rotated tooth torque orthodontic auxiliary arch device may further include an elastic patch 4.

[0062] Specifically, the elastic patch 4 is arranged at the free end of the elastic wire 3, and the elastic patch 4 is used to directly contact the labial surface of the rotated tooth to apply a torque force to the rotated tooth.

[0063] In the embodiments of the present invention, the elastic patch 4 can be made of resin, or can be composed of a steel sheet and silica gel, and the silica gel is coated outside the steel sheet. The shape of the elastic patch 4 can be arc-shaped to increase the area of contact between the elastic patch 4 and the labial surface of the rotated tooth, and the foreign body sensation of the patient is small when using it. The part of the elastic patch 4 that contacts the labial surface of the rotated tooth is made of a soft material, further reducing the foreign body sensation when the patient wears it.

[0064] Figure 3 It is a structural schematic diagram of an elastic wire provided by a specific embodiment of the present invention.

[0065] In the embodiments of the present invention, as Figure 3 shown, the cross section of the elastic wire 3 is circular or square, and the part of the free end of the elastic wire 3 that contacts the labial surface of the rotated tooth is wrapped with resin 31.

[0066] In the embodiments of the present invention, the cross section of the elastic wire 3 is circular. The part of the elastic wire 3 that contacts the labial surface of the rotated tooth is wrapped with a resin material, which can enhance the stability of the contact between the elastic wire 3 and the tooth, and the foreign body sensation is small when the patient wears it, improving the comfort of the tooth orthodontist. The elastic wire 3 can also directly abut against the labial surface part of the tooth. The cross section of the elastic wire 3 is circular or square, the cross section of the elastic wire 3 is square or polygonal, and the free end of the elastic wire 3 is in surface contact with the labial surface part of the rotated tooth, further reducing the foreign body sensation when the patient wears it.

[0067] In an embodiment of the present invention, the free end of the elastic wire 3 is in line contact or surface contact with the labial surface of the rotated tooth.

[0068] Figure 4 FIG. is a schematic diagram of the abutting position of an elastic wire provided for a specific embodiment of the present invention.

[0069] In an embodiment of the present invention, as Figure 4 shown, the free end of the elastic wire 3 abuts on the labial surface of the rotated tooth at a position 1 mm above or 1 mm below the bracket. The distance between the abutting position of the free end of the elastic wire 3 and the bracket is D.

[0070] In an embodiment of the present invention, when the free end of the elastic wire 3 abuts on the labial surface of the rotated tooth at a position 1 mm above the bracket, the crown of the rotated tooth T is rotated outwardly towards the dental arch, and the lingually inclined rotated tooth T can be corrected. When the free end of the elastic wire 3 abuts on the labial surface of the rotated tooth at a position 1 mm below the bracket, the crown of the rotated tooth T is rotated inwardly towards the dental arch, and the labially inclined rotated tooth T can be corrected. By adjusting the force application point of the free end of the elastic wire 3, in addition to applying a torque force to the rotated tooth T to correct the rotation, the lingually inclined rotated tooth T and the labially inclined rotated tooth T can also be corrected. The application range is wide, and it is flexible and convenient.

[0071] In an embodiment of the present invention, the free end of the elastic wire 3 is in line contact or surface contact with the labial surface of the rotated tooth. When the free end of the elastic wire 3 is in line contact with the labial surface of the rotated tooth, the length of the elastic wire 3 in contact with the labial surface of the rotated tooth is 1 mm to 3 mm. For example, the length of the elastic wire 3 in contact with the labial surface of the rotated tooth is 1 mm, 1.5 mm, 1.8 mm, 2 mm, 2.3 mm, 2.5 mm, 2.8 mm, 3 mm, etc. The longer the length of the elastic wire 3 in contact with the labial surface of the rotated tooth, the smaller the foreign body sensation when the patient wears it. The larger the area of the elastic wire 3 in contact with the labial surface of the rotated tooth, the smaller the foreign body sensation when the patient wears it. The free end of the elastic wire 3 is not in point contact with the labial surface portion of the rotated tooth, reducing the foreign body sensation when the patient wears it and improving the comfort of the orthodontic patient.

[0072] Figure 5 FIG. is a schematic diagram of the structure of a fixing member provided for a specific embodiment of the present invention.

[0073] In an embodiment of the present invention, as Figure 5 shown, the fixing member 1 may include at least one hook clamp 11, and the hook clamp 11 is used to movably arrange the connecting rod 2 on the main arch wire W. Wherein, the hook clamp 11 may be integrally provided with the connecting rod 2.

[0074] In an embodiment of the present invention, the hook pliers 11 can directly adopt orthodontic traction hook pliers. The hook pliers 11 can be integrally provided with the connecting rod 2, and the stability of the single-arm torsional tooth torque orthodontic auxiliary arch device is good. By using a plurality of hook pliers 11 to arrange the connecting rod 2 on the main arch wire W, the stability of the torque orthodontic auxiliary arch device can be increased, and the orthodontic effect is good.

[0075] Figure 6A It is a schematic diagram of the composition structure of a fixing member provided by a specific embodiment of the present invention.

[0076] In an embodiment of the present invention, as Figure 6A shown, the hook pliers 11 can include an upper side clamp 111 and a lower side clamp 113. The upper side clamp 111 can include a first opening end 1111. The lower side clamp 113 can include a second opening end 1131.

[0077] The hook pliers 11 itself has elasticity. When clamping the main arch wire W, it can generate deformation, as Figure 6A shown in the left figure. After clamping the main arch wire W, relying on the clamping force generated by the elastic deformation of the hook pliers 11 itself, the main arch wire W is tightly clamped, as Figure 6A shown in the right figure.

[0078] Figure 6B It is another schematic diagram of the composition structure of a fixing member provided by a specific embodiment of the present invention.

[0079] In an embodiment of the present invention, as Figure 6B shown, the hook pliers 11 can include an upper side clamp 111, a hinge 112, a lower side clamp 113 and an elastic member 114.

[0080] Specifically, the upper clamp 111 is arranged on the connecting rod 2. The upper clamp 111 includes a first opening end 1111 and a first rotating end 1112. The first rotating end 1112 has a first protruding portion 11121 away from the first opening end 1111. The hinge 112 is arranged on the first rotating end 1112. The lower clamp 113 is rotatably connected to the upper clamp 111 through the hinge 112. The lower clamp 113 includes a second opening end 1131 and a second rotating end 1132. The second rotating end 1132 has a second protruding portion 11321 away from the second opening end 1131. The elastic member 114 is arranged between the first protruding portion 11121 and the second protruding portion 11321. When an external force overcomes the elastic force of the elastic member 114, the first protruding portion 11121 and the second protruding portion 11321 approach each other, the first opening end 1111 and the second opening end 1131 move away from each other, and the upper clamp 111 and the lower clamp 113 clamp the main arch wire W. When the external force disappears, the upper clamp 111 and the lower clamp 113 clamp the main arch wire W under the action of the elastic force of the elastic member 114.

[0081] In an embodiment of the present invention, the elastic member 114 may include a spring, a spring piece, etc. The cross-section of the main arch wire W may be square or rectangular. The surfaces of the upper clamp 111 and the lower clamp 113 in contact with the main arch wire W are flat, and the cross-section of the main arch wire W is square. The hook pliers 11 are clamped on the main arch wire W and will not rotate, which can increase the stability of the torque orthodontic auxiliary arch device and has good orthodontic efficacy. The single-arm torsion tooth torque orthodontic auxiliary arch device provided by the present invention is fixed on the main arch wire W by using the hook pliers 11. Without disassembling the main arch wire W, the single-arm torsion tooth torque orthodontic auxiliary arch device provided by the present invention can be installed, and without disassembling the main arch wire W, the single-arm torsion tooth torque orthodontic auxiliary arch device provided by the present invention can be disassembled. When reviewing, the main arch wire W does not need to be removed, which greatly reduces the operation difficulty, reduces the chairside time, and improves the diagnosis and treatment efficiency.

[0082] Figure 7 It is a schematic diagram of the shape of an elastic wire provided by a specific embodiment of the present invention.

[0083] In an embodiment of the present invention, as Figure 7 shown, the shape of the elastic wire 3 may be a folded shape or a spiral shape.

[0084] In an embodiment of the present invention, when the shape of the elastic steel wire 3 is a folded shape, the larger the bending angle (i.e., the smaller the bending line angle), the larger the torque force applied to the twisted tooth, and the more significant the force applied to the twisted tooth; the smaller the bending angle (i.e., the larger the bending line angle), the smaller the torque force applied to the twisted tooth, and the less significant the force applied to the twisted tooth. When the shape of the elastic steel wire 3 is a folded shape, during a follow-up visit, it is only necessary to adjust the bending angle and / or force application position of the elastic steel wire 3 to adjust the force. When the shape of the elastic steel wire 3 is a spiral, the smaller the diameter of the turn of the steel wire, the larger the torque force applied to the twisted tooth, and the more significant the force applied to the twisted tooth; the larger the diameter of the turn of the steel wire, the smaller the torque force applied to the twisted tooth, and the less significant the force applied to the twisted tooth. Reduce the difficulty of operation during follow-up visits for patients, reduce chairside time, and improve diagnosis and treatment efficiency.

[0085] In an embodiment of the present invention, when the elastic steel wire 3 is in a folded shape, the elastic steel wire 3 has 3 to 6 steel wire folded segments, for example, the elastic steel wire 3 has 3 steel wire folded segments, 4 steel wire folded segments, 5 steel wire folded segments or 6 steel wire folded segments, etc. The lengths of the steel wire folded segments may be different or the same. When the elastic steel wire 3 is in a spiral shape, the elastic steel wire 3 has 3 to 5 turns of steel wire, for example, the elastic steel wire 3 has 3 turns of steel wire, 4 turns of steel wire or 5 turns of steel wire, etc. The diameters of the turns of steel wire may be different or the same.

[0086] In the embodiment of the present invention, the more wire segments the elastic wire 3 has, the larger the range of the torque force applied to the twisted teeth; the more turns the elastic wire 3 has, the larger the range of the torque force applied to the twisted teeth. The flexibility and convenience of the single-arm torque orthodontic auxiliary arch device for twisting teeth are increased, the operation is more convenient, the chairside time is reduced, and orthodontic diagnosis and treatment are more efficient.
