[0016] The method of using the orthodontic lingual wire placement plate includes the following steps:

[0017] The first step is to prepare for surgery:

[0018] Isolation: Strictly isolate saliva and ensure that the operating area (usually the lingual side of the mandibular or maxillary front teeth) is absolutely dry, such as using a saliva suction device, cotton roll or rubber dam.

[0019] Tooth surface cleaning: Use a polishing cup and polishing paste to thoroughly clean the tooth surface, especially the tongue side.

[0020] Acid etching: Apply an acid etchant (35% phosphoric acid) to the tooth surface to be bonded, leave it on for a certain period of time, and then rinse and dry it thoroughly; at this time, the tooth surface should appear chalky white.

[0021] The second step is to apply a layer of adhesive on the acid-etched tooth surface, attach the load-bearing plate to the adhesive, and use a light-curing lamp to initially illuminate the tooth.

A tension mechanism is provided on the inverted plate, and the tension mechanism can apply a tension to the lingual wire. The inverted plate applies a tension to the teeth fixed thereto by means of the reaction force of the tension mechanism.

[0025] 2. The orthodontic lingual wire-positioned inverted plate and its usage method: the entire inverted plate adopts a split design, that is, it is divided into a force-bearing structure and a fixed structure. The notch and the tension mechanism are both set on the fixed structure. When the tooth where the inverted plate is located is corrected to the expected position, the fixed structure is then removed as a whole, the force-bearing structure is no longer stressed, and the foreign body sensation in the mouth is reduced (the fewer inverted plates in the mouth, the more comfortable the patient).

[0036] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1-Figure 2 As shown, the orthodontic lingual wire placement plate of the present invention includes a force-bearing structure and a fixing structure. The force-bearing structure includes a force-bearing plate 1, which is used to be fixed to the teeth. The fixing structure includes a connecting plate 3. A notch is provided on the outer side of the connecting plate 3, and a clamping structure is provided inside the notch. The connecting plate 3 is buckled on the lingual wire through the notch and fixed to the lingual wire through the clamping structure. A tension structure for adjusting the distance between the force-bearing plate 1 and the connecting plate 3 is provided;

[0038] From the above connection relationship, it can be seen that: using the common lingual wire correction method, a notch is opened on the outer side of the connecting plate 3, and the connecting plate 3 is buckled on the lingual wire through the notch. A tension structure for adjusting the distance between the force plate 1 and the connecting plate 3 is provided. The tension mechanism can apply a tension to the lingual wire, and the force plate 1 applies a tension to the teeth fixed thereto with the help of the reaction force of the tension mechanism. It can be seen that the inverted plate is no longer limited to playing a connecting role, and can also adjust the tension on the teeth.

[0039] Specifically, the four corners of the force-bearing plate 1 are all rounded with a radius of 0.5-1mm, and the side of the force-bearing plate 1 fixed to the teeth is a curved surface 2 that fits the physiological morphology of the labial and buccal surfaces of the teeth. The curvature radius of the curved surface 2 and the curvature radius of the corresponding labial and buccal surfaces of the teeth do not exceed 0.2mm.

[0040] It should be noted that the design of the curved surface 2 is mainly customized according to the patient's teeth, and the specific implementation method adopts the existing technology in this field, so it will not be detailed again;

[0041] It should be further explained that the rounded corners of the stress plate 1 are to prevent the stress plate 1 from scratching the tongue;

[0042] From the above connection relationship, it can be seen that: a layer of adhesive is applied on the acid-etched tooth surface, the load-bearing plate 1 is attached to the adhesive, and a light curing lamp is used for preliminary illumination.

[0043] Specifically, the entire corners of the connecting plate 3, including the corners where the connecting plate 3 is connected to the tension structure, the corners of the notch edges, and the contour corners of the connecting plate 3 itself, are all rounded with a radius of 0.3-0.8mm.

[0044] It should be noted that the rounded corners of the connecting plate 3 are to prevent the force-bearing plate 1 from scratching the tongue.

[0045] Specifically, the outer surfaces of the load-bearing plate 1 and the connecting plate 3 are precision polished, and the surface roughness after polishing is Ra ≤ 0.8 μm. Through the polishing process, the outer surfaces of the load-bearing plate 1 and the connecting plate 3 can be smooth and flat;

[0046] It should be noted that the outer surface of the load-bearing plate 1 and the outer surface of the connecting plate 3 are polished in order to improve comfort and reduce friction between the outer surface of the load-bearing plate 1 and the outer surface of the connecting plate 3 and the tongue.

[0047] Specifically, the clamping structure includes a clamping plate 6 and a first adjusting stud 4. A groove 12 is provided on one side of the recess. The entire clamping plate 6 is slidably embedded in the groove 12. A first threaded hole communicating with the recess is provided on the outer side of the connecting plate 3. The outer side of the column of the first adjusting stud 4 is threadedly installed in the first threaded hole. One end of the first adjusting stud 4 is rotatably installed on the clamping plate 6.

[0048] From the above connection relationship, it can be seen that: by twisting the first adjusting stud 4, the first adjusting stud 4 pushes the clamping plate 6 out of the groove 12 through thread transmission until the clamping plate 6 contacts the lingual wire in the recess.

[0049] Specifically, the tension structure includes a second adjusting stud 5 and a transverse plate 9. A straight groove 13 is provided on the outer side of the connecting plate 3. Rotation holes 14 are provided at both ends of the straight groove 13. The two ends of the second adjusting stud 5 are respectively rotatably installed in the two rotation holes 14. The entire transverse plate 9 is located in the straight groove 13, and the two ends of the transverse plate 9 are respectively in contact with the two sides of the straight groove 13. A second threaded hole is provided on the outer side of the transverse plate 9. The outer side of the second adjusting stud 5 is threadedly installed in the second threaded hole.

[0050] From the above connection relationship, it can be seen that: by twisting the second adjusting stud 5, the column of the second adjusting stud 5 drives the cross plate 9 to move through the form of thread transmission. Since the two ends of the cross plate 9 are respectively in contact with the two sides of the straight groove 13, the cross plate 9 can only move linearly within the straight groove 13.

[0051] Specifically, the tension structure also includes two straight plates 7, an extension plate 10 and a cylinder 11. The two ends of the extension plate 10 are respectively fixed to the cylinder 11 and the horizontal plate 9. The two straight plates 7 are fixed to the load-bearing plate 1. The two straight plates 7 are provided with a slide groove 8 on the opposite side. The two ends of the cylinder 11 are respectively arranged in the slide groove 8.

[0052] From the above connection relationship, it can be seen that: when the horizontal plate 9 moves, the horizontal plate 9 drives the cylinder 11 to move through the extension plate 10. In the actual installation of the force-bearing plate 1, the force-bearing plate 1 fits with the teeth, and the force-bearing plate 1 is inclined. When the cylinder 11 slides in the slide groove 8, the cylinder 11 applies a pulling force to the inner wall of the slide groove 8. The pulling force is transmitted through the straight plate 7, so that the cylinder 11 generates a pulling force on the force-bearing plate 1.

[0053] Specifically, one end of the first adjusting stud 4 away from the pressing plate 6 and one end of the second adjusting stud 5 are both provided with a wire groove with a regular hexagonal or straight cross section. The depth of the wire groove is 1-2 mm, and the width of the groove matches the size of the corresponding adjustment tool. The gap error does not exceed 0.1 mm.

[0054] It should be noted that the cable duct is provided to facilitate twisting using tools.

[0055] Specifically, when the entirety of the pressing plate 6 is completely embedded in the groove 12, one end of the first adjusting stud 4 is flush with the outer side of the connecting plate 3, and both ends of the second adjusting stud 5 are flush with the top and bottom of the connecting plate 3 respectively;

[0056] It should be noted that the above arrangement is intended to hide the first adjusting stud 4 and the second adjusting stud 5 .

[0057] Working principle of orthodontic lingual wire placement plate:

[0058] Apply a layer of adhesive to the tooth surface after acid etching, attach the force plate 1 to the adhesive, and initially illuminate it with a light curing lamp; the connecting plate 3 is buckled onto the lingual wire through the notch;

[0059] Twist the first adjusting screw 4, and the first adjusting screw 4 pushes the pressing plate 6 out of the groove 12 through thread transmission until the pressing plate 6 contacts the lingual wire in the notch;

[0060] Twist the second adjusting screw 5, and the column of the second adjusting screw 5 drives the cross plate 9 to move through the form of thread transmission. Since the two ends of the cross plate 9 are in contact with the two sides of the straight groove 13 respectively, the cross plate 9 can only move linearly in the straight groove 13. When the cross plate 9 moves, the cross plate 9 drives the cylinder 11 to move through the extension plate 10. In the actual installation of the force-bearing plate 1, the force-bearing plate 1 fits with the teeth, and the force-bearing plate 1 is inclined. When the cylinder 11 slides in the slide groove 8, the cylinder 11 applies a pulling force to the inner wall of the slide groove 8. The pulling force is transmitted through the straight plate 7, so that the cylinder 11 generates a pulling force on the force-bearing plate 1;

[0061] In summary, the inverted plate is no longer limited to playing a connecting role, but can also adjust the tension on the teeth. The entire inverted plate adopts a split design, that is, it is divided into a force-bearing structure and a fixed structure. The recess and the tension mechanism are both set on the fixed structure. When the teeth where the inverted plate is located are corrected to the expected position, the fixed structure is then removed as a whole, and the force-bearing structure is no longer under stress, reducing the foreign body sensation in the mouth (the fewer inverted plates in the mouth, the more comfortable the patient will be).

[0062] The method of using the orthodontic lingual wire placement plate includes the following steps:

[0063] The first step is to prepare for surgery:

[0064] Isolation: Strictly isolate saliva and ensure that the operating area (usually the lingual side of the mandibular or maxillary front teeth) is absolutely dry, such as using a saliva suction device, cotton roll or rubber dam.

[0065] Tooth surface cleaning: Use a polishing cup and polishing paste to thoroughly clean the tooth surface, especially the tongue side.

[0066] Acid etching: Apply an acid etchant (35% phosphoric acid) to the tooth surface to be bonded, leave it on for a certain period of time, and then rinse and dry it thoroughly; at this time, the tooth surface should appear chalky white.

[0067] The second step is to apply a layer of adhesive on the acid-etched tooth surface, attach the force plate 1 to the adhesive, and use a light curing lamp to initially illuminate it. Repeat this operation for each tooth position to ensure that each force plate 1 is tightly attached and firmly bonded;

[0068] The third step is to place the pre-bent lingual wire (or the finished chain wire) at the ideal position on the lingual side of the tooth, snap the connecting plate 3 onto the lingual wire through the notch and fix it to the lingual wire through the clamping structure, then adjust the tension structure and the distance between the force-bearing plate 1 and the connecting plate 3;

[0069] The working process of the clamping structure in the third step is to twist the first adjusting stud 4, which pushes the pressing plate 6 out of the groove 12 through thread transmission until the pressing plate 6 contacts the lingual wire in the notch;

[0070] The working process of the third step tension structure is to twist the second adjusting stud 5, and the column of the second adjusting stud 5 drives the cross plate 9 to move through the form of threaded transmission. Since the two ends of the cross plate 9 are respectively in contact with the two sides of the straight groove 13, the cross plate 9 can only move linearly in the straight groove 13. When the cross plate 9 moves, the cross plate 9 drives the cylinder 11 to move through the extension plate 10. In the actual installation of the force plate 1, the force plate 1 fits with the teeth, and the force plate 1 is inclined. When the cylinder 11 slides in the slide groove 8, the cylinder 11 applies a pulling force to the inner wall of the slide groove 8. The pulling force is transmitted through the straight plate 7, so that the cylinder 11 generates a pulling force on the force plate 1.
