Abstract
Description
Technical Field
[0001] The utility model relates to the field of oral orthodontics, in particular to a double-wire lingual appliance. Background Art
[0002] The lingual braces are a type of fixed braces. The basic correction effect is achieved by bonding the lingual brackets to the lingual side of the teeth and passing the archwire through the lingual brackets. In the later stages of correction, in order to achieve fine adjustment of the teeth, alignment, or control of torque, axial tilt, etc., an auxiliary tube is usually installed on the bracket to assist in the adjustment.
[0003] Orthodontic patients often have deep overbites. In addition to using archwires to correct tooth alignment, these patients also need to open the bite relationship, usually using a flat guide device to lower the front teeth and raise the back teeth, thereby opening the bite of the upper and lower teeth.
[0004] When an auxiliary tube is required, a hole is required in the lingual bracket, and the strength of the lingual bracket must be ensured during the casting process. Therefore, the lingual bracket must be of sufficient thickness and will occupy a certain space in the oral cavity after bonding. At the same time, since an auxiliary tube must be inserted into the bracket and a flat guide device must be worn in the oral cavity, the already limited oral space becomes even narrower, and the patient has a strong sense of discomfort and foreign body sensation in the oral cavity, and is prone to slurred speech in daily life. In addition, when replacing the archwire or cleaning the oral cavity, the flat guide must be frequently removed and worn to expose the lingual bracket, which is troublesome to maintain, and the doctor does not have enough space to operate in the mouth during follow-up visits. Utility Model Content
[0005] In order to overcome the deficiencies of the prior art, the purpose of the present utility model is to provide a double-wire lingual appliance, which can solve the problem that the existing double-wire lingual appliance is difficult to correct deep overbite.
[0006] The utility model is realized by the following technical solutions:
[0007] A double-wire lingual orthodontic appliance comprises: a lingual bracket, comprising: a base plate, a flat guide plate and a body; the body is fixed to the base plate, the flat guide plate is integrally formed or fixedly connected to the upper end of the base plate, and the top of the flat guide plate is formed with a flat guide surface for abutting against the patient's upper front teeth; the interior of the flat guide plate is provided with a through auxiliary tube hole along the mesiodistal direction; an auxiliary tube is passed through the auxiliary tube hole of the flat guide plate; a main arch wire is passed through the body; when the patient's upper and lower jaws are in a occlusal state, the patient's upper front teeth abut against the flat guide surface of the flat guide plate to open the occlusal relationship between the upper and lower teeth.
[0008] Furthermore, the flat guide plate and the bottom plate are integrally cast.
[0009] Further, the flat guide surface of the flat guide plate is flush with the top end of the bottom plate.
[0010] Further, the port of the auxiliary tube hole is a beveled end, and the beveled end is inclined relative to the surface of the bottom plate.
[0011] Further, the port of the auxiliary tube hole has a flared structure that expands outward in the radial direction thereof.
[0012] Further, a concave structure is provided on the inner side wall of the auxiliary tube hole; when the auxiliary tube is inserted into the auxiliary tube hole, the concave structure is fastened to the outer surface of the auxiliary tube.
[0013] Further, the auxiliary tube is a stainless steel tube.
[0014] Further, the body portion includes: an arch wire groove, the shape of the arch wire groove matches the shape of the main arch wire, and the main arch wire is inserted into the arch wire groove.
[0015] Further, the body portion includes: an upper ligation wing and a lower ligation wing; the upper ligation wing and the lower ligation wing extend in a wing shape along both sides of the body portion.
[0016] Further, the inner diameter of the auxiliary tube is 0.3 mm to 0.6 mm, and the wall thickness is 0.05 mm to 0.2 mm.
[0017] Compared with the prior art, the beneficial effects that the present utility model can achieve are:
[0018] A flat guide plate is formed on the upper end of the bottom plate of the lingual bracket, and an auxiliary tube hole for installing an auxiliary tube is opened in the flat guide plate along the mesiodistal direction. The main arch wire and the auxiliary tube are simultaneously inserted through the lingual bracket, achieving the effect of joint cooperation of the two wires for orthodontic treatment. At the same time, when the patient bites, the upper anterior teeth will abut against the flat guide surface of the flat guide plate, thereby achieving the effect of depressing the anterior teeth and elevating the posterior teeth.
[0019] (1) Since the auxiliary tube hole is opened in the flat guide plate, there is no need to form a through-hole structure on the bottom plate. Thus, during casting, the bottom plate can be cast with a thinner thickness while maintaining sufficient strength. In lingual orthodontics, a thinner bracket thickness means that the foreign body sensation in the patient's mouth is significantly reduced. (2) In the past, the flat guide device needed to be sleeved on the tooth surface or worn on the upper jaw, occupying a large amount of oral space and affecting the patient's daily speech. The flat guide plate of the present utility model is formed on the lingual side of the bracket, reducing the oral space occupied by the previous flat guide device, having a higher degree of structural integration, reducing the foreign body sensation in the patient's mouth, and providing more sufficient oral operation space for the doctor. (3) When the arch wire needs to be replaced, there is no need to remove the flat guide device as in the past, but the operation can be directly performed on the bracket, saving the follow-up visit time and being more convenient for daily maintenance.

[0028] Refer to Figures 1-3 , the present utility model discloses a double - wire lingual appliance, including: a lingual bracket 10, an auxiliary tube 20 and a main arch wire 30. Among them, the lingual bracket 10 includes a base plate 11, a flat guide plate 12 and a body part 13; the base plate 11 has an adhesive surface for bonding to the lingual surface of the tooth, and the body part 13 and the flat guide plate 12 are arranged on the opposite surfaces of the adhesive surface of the base plate 11. The flat guide plate 12 is integrally formed or fixedly connected to the upper end of the base plate 11. Preferably, the flat guide plate 12 and the base plate 11 are integrally cast. A flat guide surface for abutting against the upper anterior teeth of the patient is formed at the top of the flat guide plate 12. When the upper and lower jaws of the patient are in the occlusal state, the upper anterior teeth of the patient abut against the flat guide surface of the flat guide plate 12, thereby depressing the anterior teeth and providing space for the posterior teeth to erupt, so as to open the occlusal relationship between the upper and lower teeth. An axially - through auxiliary tube hole 14 is formed in the flat guide plate 12 along the mesiodistal direction, and the auxiliary tube 20 is inserted into the auxiliary tube hole 14 of the flat guide plate 12; the main arch wire 30 is inserted through the body part 13. Thus, the main arch wire 30 and the auxiliary tube 20 form a double - wire orthodontic structure. The main arch wire 30 releases the main orthodontic force to change the tooth arrangement, and the auxiliary tube 20 releases the auxiliary orthodontic force to achieve fine adjustment of the tooth arrangement.
[0029] In the present utility model:
[0030] (1) Since the auxiliary tube hole 14 is formed in the flat guide plate 12, there is no need to form a through - hole structure on the base plate 11. In this way, during casting, the base plate 11 can be cast with a thinner thickness while maintaining sufficient strength. In lingual orthodontics, a thinner bracket thickness means that the foreign body sensation in the patient's mouth is significantly reduced. (2) In the past, the flat guide device needed to be sleeved on the tooth surface or worn on the upper jaw, occupying a large amount of oral space and affecting the patient's daily speech. The flat guide plate 12 of the present utility model is formed on the lingual surface of the bracket, reducing the oral space occupied by the conventional flat guide device, having a higher degree of structural integration, reducing the foreign body sensation in the patient's mouth, and providing more sufficient oral operation space for the doctor. (3) When it is necessary to replace the arch wire, there is no need to remove the flat guide device as in the past, but the operation can be directly performed on the bracket, saving the review time and being more convenient for daily maintenance.
[0031] Preferably, the flat guide surface of the flat guide plate 12 is flush with the top end of the base plate 11, so that the connection between the flat guide plate 12 and the base plate 11 is smoother, and the flat guide surface and the top end of the base plate 11 can jointly abut against the upper anterior teeth.
[0032] Preferably, refer to Figure 1 , the port of the auxiliary tube hole 14 is a bevel - cut end, and the bevel - cut end is inclined relative to the upper surface of the base plate 11. The cut of the auxiliary tube hole 14 is an inclined surface, so the cut area is larger, which has a certain guiding effect on the insertion of the auxiliary tube 20.
[0033] Preferably, referring to Figure 1 , the port of the auxiliary tube hole 14 has a flared structure that expands outward in its radial direction. Such a flared design can make it easier to insert the auxiliary tube 20 into the hole when passing through, improving the installation simplicity.
[0034] Preferably, a concave structure is provided on the inner side wall of the auxiliary tube hole 14 for fastening the auxiliary tube 20. When the auxiliary tube 20 is inserted into the auxiliary tube hole 14, the concave structure fastens on the outer surface of the auxiliary tube 20, making the installation of the auxiliary tube 20 more secure.
[0035] Preferably, the auxiliary tube 20 is made of a stainless steel tube. More preferably, a finished stainless steel tube with an inner diameter of 0.3 - 0.6 mm and a wall thickness of 0.05 - 0.2 mm is used.
[0036] Preferably, the body portion 13 includes a wire groove 131 for installing the main arch wire 30. The shape of the wire groove 131 matches the shape of the main arch wire 30, and the main arch wire 30 is inserted into the wire groove 131. More preferably, the body portion 13 further includes an upper ligation wing 132 and a lower ligation wing 133, which extend outward in a wing shape along both sides of the body portion 13 for hanging orthodontic auxiliary accessories such as rubber bands or ligation loops.
[0037] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
