Technical Field

[0001] The present application relates to the technical field of orthodontic appliances, and in particular to a double-plate orthodontic appliance. Background Art

[0002] At present, in the field of orthodontics, braces are medical devices used to correct irregular tooth arrangement and malocclusion. And with the improvement of people's requirements for beauty and comfort, a variety of new braces have appeared on the market, including ceramic brackets, transparent braces, etc. Among them, transparent braces are generally made of safe elastic transparent polymer materials, which can be freely removed and worn by patients or doctors, and are retained by the clamping effect of the clasp and the adsorption effect of the mucosa to achieve the purpose of correcting malocclusion. In related technologies, in order to improve the corrective force of the brace, a bevel guide plate is usually integrally formed on the brace to achieve the auxiliary correction function after the patient's upper and lower teeth are bitten.

[0003] Regarding the related technologies mentioned above: the bevel guide plate is integrally formed with the appliance, so when the bevel guide plate on the appliance is damaged or needs to be adjusted, the appliance can usually only be replaced as a whole, thereby increasing costs. Utility Model Content

[0004] In order to reduce costs, the present application provides a double-plate appliance.

[0005] The present application provides a double-plate appliance, which adopts the following technical solution:

[0006] A double-plate orthodontic appliance comprises upper braces and lower braces, wherein the upper braces are detachably connected to an upper bite plate, and the lower braces are detachably connected to a lower bite plate, and the upper bite plate and the lower bite plate are respectively provided with an occlusal inclined surface. When the upper braces and the lower braces are engaged, the occlusal inclined surface on the upper bite plate is in contact with the occlusal inclined surface on the lower bite plate to guide the movement of the upper bite plate and the lower bite plate.

[0007] By adopting the above technical solution, the occlusal slopes on the upper and lower bite plates fit together when the upper and lower braces are occluded, which can guide the movement of the upper and lower braces to achieve the effect of auxiliary correction; at the same time, since the upper bite plate is detachably connected to the upper braces and the lower bite plate is detachably connected to the lower braces, both the upper and lower bite plates can be replaced, and the upper and lower braces can be reused, which is beneficial to reduce the cost of the orthodontic appliance and reduces the processing time to a certain extent.

[0008] Optionally, the upper bite plate is bonded to the upper braces, and the lower bite plate is bonded to the lower braces, and both the upper bite plate and the lower bite plate can be debonded by ultraviolet irradiation.

[0009] By adopting the above technical solution, when the upper and lower bite plates need to be replaced, the bonding is released by ultraviolet irradiation, so that the upper bite plate is separated from the upper braces, and the lower bite plate is separated from the lower braces, thereby facilitating the rapid replacement of the upper and lower bite plates, and facilitating the replacement of upper and lower bite plates of different shapes or inclination angles according to the needs of different stages of correction, thereby better guiding the adjustment of the upper and lower jaw positions, improving the correction effect, and reducing the time and cost required to replace the bite plates.

[0010] Optionally, connecting pieces are provided between the upper braces and the upper bite plate, and between the lower braces and the lower bite plate, respectively. The connecting pieces are used to fix the upper bite plate to the upper braces, and to fix the lower bite plate to the lower braces.

[0011] By adopting the above technical solution, the setting of the connecting parts enables the upper and lower bite plates to be firmly fixed on the upper and lower braces, thereby achieving a stable occlusal relationship and ensuring the correct fit of the occlusal bevels.

[0012] Optionally, the connecting member includes a screw and a nut, the screw is provided on the upper bite plate and the lower bite plate, the nut is provided on the upper braces and the lower braces, and the screw is threadedly connected to the nut.

[0013] By adopting the above technical solution, the upper occlusal plate is threadedly connected to the nut on the upper braces by screws, and the lower occlusal plate is threadedly connected to the nut on the lower braces by screws. This connection method not only facilitates the rapid installation and disassembly of the upper and lower occlusal plates, but also ensures the precise docking of the occlusal bevels, thereby effectively guiding the correct occlusal position adjustment between the upper and lower braces, achieving more precise correction effects, while simplifying the manufacturing process and reducing costs.

[0014] Optionally, a sealing material is filled between the upper bite plate and the upper braces, and between the lower bite plate and the lower braces.

[0015] By adopting this technical solution, the gaps between the upper bite plate and upper braces, as well as between the lower bite plate and lower braces, are filled with sealing material, preventing food debris from entering the braces due to gaps during occlusion. This improves the hygiene and comfort of the braces, extending their lifespan. Furthermore, the use of sealing material allows the bite plate to be more firmly attached to the braces, enhancing the patient experience without compromising the overall structural strength.

[0016] Optionally, the sealing material is rubber.

[0017] By adopting the above technical solution and using rubber as the sealing material, not only can a tight connection between the upper bite plate and the upper braces, and a tight connection between the lower bite plate and the lower braces be ensured, but a certain degree of elasticity can also be provided, making the patient more comfortable during the bite process.

[0018] Optionally, the connecting part includes a fixed sleeve and an elastic plug-in column, and the upper braces and the lower braces are respectively provided with mounting holes, the fixed sleeve is coaxially arranged in the mounting hole, and the elastic plug-in column is provided on the upper bite plate and the lower bite plate, and the elastic plug-in column is inserted in the fixed sleeve and has an interference fit with the fixed sleeve.

[0019] By adopting the above technical solution, the coordinated design of the fixed sleeve and the elastic plug-in column enables the upper and lower bite plates to be firmly installed on the upper and lower braces, and ensures the accurate positioning of the occlusal bevels. The interference fit between the elastic plug-in column and the fixed sleeve not only enhances the stability of the upper and lower bite plates, but also facilitates the replacement of bite plates of different shapes, thereby achieving a more precise correction effect.

[0020] Optionally, the fixing sleeve may be made of stainless steel, titanium alloy or high molecular polymer.

[0021] By adopting the above technical solution, the fixed sleeve is made of stainless steel, titanium alloy or high molecular polymer material. On the one hand, it is beneficial to enhance the structural strength and durability of the fixed sleeve, so that when the elastic plug-in column is inserted into the fixed sleeve, the fixed sleeve is not easily deformed, so that the upper and lower braces are not easily deformed, thereby facilitating the upper and lower braces to stably and accurately achieve the correction effect; on the other hand, it can also ensure a stable interference fit between the elastic plug-in column and the fixed sleeve, which is beneficial to improve the connection stability between the upper occlusal plate and the upper braces, and improve the connection stability between the lower occlusal plate and the lower braces, further ensuring the correction effect.

[0022] Optionally, a first magnetic sheet is provided in the fixing sleeve, and reinforcing ribs are embedded in the elastic plug-in column along its own length direction, and the first magnetic sheet is used to absorb the reinforcing ribs.

[0023] By adopting this technical solution, the first magnetic plate within the fixed sleeve and the reinforcing ribs within the elastic plug-in posts attract each other, making the connection between the upper and lower bite plates and the upper and lower braces more secure and stable. This magnetic attraction not only facilitates removal and replacement but also improves the positioning accuracy of the bite plates, ensuring accurate alignment of the occlusal slopes during treatment, effectively guiding the upper and lower jaw positions for correction and reducing correction errors. Furthermore, the reinforcing ribs embedded within the elastic plug-in posts prevent them from bending, further facilitating their stable support of the upper and lower bite plates.

[0024] Optionally, the upper bite plate and the lower bite plate are respectively provided with protrusions, the upper braces and the lower braces are respectively provided with grooves, and the protrusions are inserted into the grooves.

[0025] By adopting the above technical solution, the protrusions on the upper and lower bite plates are respectively inserted into the grooves of the upper and lower braces, which not only achieves rapid positioning and installation between the bite plate and the braces, but also enhances the stability of the bite plate.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By detachably connecting the upper bite plate to the upper braces and the lower bite plate to the lower braces, the upper and lower bite plates can guide the movement paths of the upper and lower braces to achieve the effect of auxiliary correction. At the same time, the upper and lower bite plates can be replaced, and the upper and lower braces can be reused, so that it is convenient to replace the upper and lower bite plates with different shapes or inclination angles according to the needs of different stages of correction, thereby helping to reduce the cost of the braces and to a certain extent shorten the processing time;

[0028] 2. The upper and lower bite plates can be replaced by removing the adhesive by ultraviolet light, which simplifies the replacement process, reduces costs and reduces processing time;

[0029] 3. The upper and lower bite plates are fixed to the upper and lower braces with screws and nuts, which ensures structural stability and facilitates the quick installation and removal of the upper and lower bite plates;

[0030] 4. Through the mutual cooperation of the fixed sleeve and the elastic plug-in column, the upper and lower bite plates can be firmly installed on the upper and lower braces, and ensure the accurate positioning of the occlusal bevel. The interference fit between the elastic plug-in column and the fixed sleeve not only enhances the stability of the upper and lower bite plates, but also facilitates the replacement of bite plates of different shapes, thereby achieving a more precise correction effect.

[0037] The following is combined with Figure 1-4 This application is described in further detail.

[0038] The embodiments of the present application disclose a double-plate appliance.

[0039] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] Example 1

[0041] Reference Figure 1 The double-plate appliance includes an upper brace 1 and a lower brace 2. An upper bite plate 3 is detachably connected to the upper brace 1, and a lower bite plate 4 is detachably connected to the lower brace 2. Each of the upper and lower bite plates 3 and 4 is provided with an occlusal slope 31. When the upper and lower braces 1 and 2 are engaged, the occlusal slope 31 on the upper and lower bite plates 3 mate with the occlusal slope 31 on the lower bite plate 4 to guide the movement of the upper and lower bite plates 3 and 4, thereby effectively adjusting the position of the teeth.

[0042] Reference Figure 1 and Figure 2 The upper and lower braces 1 and 2 are respectively provided with grooves 11, and the upper and lower bite plates 3 and 4 are respectively integrally formed with protrusions 32, and the protrusions 32 can be inserted into the grooves 11, thereby facilitating the rapid positioning between the bite plate and the braces.

[0043] The upper bite plate 3 is bonded to the upper braces 1, and the lower bite plate 4 is bonded to the lower braces 2. In this embodiment, the upper bite plate 3 and the upper braces 1, and the lower bite plate 4 and the lower braces 2 are bonded together using dental adhesive.

[0044] When the upper bite plate 3 and the lower bite plate 4 need to be replaced, the bonding can be released by irradiating the bonding position with ultraviolet light to separate the upper bite plate 3 from the upper braces 1, and the lower bite plate 4 from the lower braces 2, so as to facilitate the rapid replacement of the upper bite plate 3 and the lower bite plate 4, so as to facilitate the replacement of upper bite plates 3 and lower bite plates 4 of different shapes or inclination angles according to the needs of different stages of correction, thereby facilitating better guidance of the adjustment of the upper and lower jaw positions, improving the correction effect, and reducing the time and cost required to replace the bite plates.

[0045] Example 2

[0046] Reference Figure 1 and Figure 3 The difference between this embodiment and embodiment 1 is that a connecting piece 5 is provided between the upper brace 1 and the upper bite plate 3, and between the lower brace 2 and the lower bite plate 4.

[0047] In this embodiment, the connector 5 includes screws 51 and nuts 52. Mounting holes 33 are provided in the upper and lower bite plates 3 and 4, respectively. The screws 51 are secured to the upper and lower bite plates 3 and 4 through the mounting holes 33. The number of nuts 52 is equal to the number of screws 51, and multiple nuts 52 are embedded in the upper and lower braces 1 and 2, respectively.

[0048] When it is necessary to connect and fix the upper bite plate 3 to the upper braces 1, and connect and fix the lower bite plate 4 to the lower braces 2, first insert the protrusion 32 on the upper bite plate 3 into the groove 11 on the upper braces 1, and insert the protrusion 32 on the lower bite plate 4 into the groove 11 on the lower braces 2, and then pass the screw 51 through the mounting hole 33 and threadedly connect it with the nut 52, so as to realize the connection and fixation of the upper bite plate 3 to the upper braces 1, and realize the connection and fixation of the lower bite plate 4 to the lower braces 2.

[0049] Reference Figure 1 and Figure 3 A sealing material 12 is filled between the upper bite plate 3 and the upper braces 1, and between the lower bite plate 4 and the lower braces 2. In this embodiment, the sealing material 12 is a meltable rubber, which facilitates the use of the sealing material 12 to fill the gaps between the upper bite plate 3 and the upper braces 1, and between the lower bite plate 4 and the lower braces 2. This prevents food debris from entering the braces due to gaps during occlusion, thereby improving the hygiene and comfort of the braces and extending the life of the braces. The sealing material 12 can also be filled into the mounting holes 33 to ensure the smooth surfaces of the upper and lower bite plates 3 and 4, further improving the hygiene and comfort of the braces and extending the life of the braces.

[0050] When the upper and lower bite plates 3 and 4 need to be disassembled, the rubber is first melted, and then the screws 51 and nuts 52 are separated, so as to facilitate the removal of the upper and lower bite plates 3 from the upper braces 1 and the removal of the lower and lower bite plates 4 from the lower braces 2, thereby realizing the disassembly of the upper and lower bite plates 3 and 4.

[0051] Example 3

[0052] Reference Figure 1 and Figure 4 The difference between this embodiment and embodiment 2 is that the connecting member 5 includes a fixing sleeve 53 and an elastic plug-in column 54.

[0053] One elastic plug post 54 is connected and fixed to the upper bite plate 3, and the other elastic plug post 54 is connected and fixed to the lower bite plate 4. In this embodiment, the elastic plug post 54 is made of elastic material, so that the elastic plug post 54 has a certain elasticity.

[0054] The upper braces 1 and the lower braces 2 are respectively provided with accommodating holes 13. The number of accommodating holes 13 is equal to the number of elastic plug-in columns 54, and a fixing sleeve 53 is coaxially installed in a accommodating hole 13, so as to facilitate the connection and fixation of the fixing sleeve 53 with the upper braces 1 or the lower braces 2.

[0055] When it is necessary to connect and fix the upper bite plate 3 to the upper braces 1, and the lower bite plate 4 to the lower braces 2, the elastic plug-in column 54 is directly inserted into the fixing sleeve 53, so that the elastic plug-in column 54 and the fixing sleeve 53 have an interference fit, thereby facilitating the secure installation of the upper and lower bite plates 3 and 4 on the upper and lower braces 1 and 2, and ensuring the accurate positioning of the occlusal bevel 31. When it is necessary to replace the upper and lower bite plates 3 and 4, the elastic plug-in column 54 is directly withdrawn from the fixing sleeve 53 to replace the upper and lower bite plates 3 and 4.

[0056] In this embodiment, the fixed sleeve 53 can be made of stainless steel, titanium alloy or high molecular polymer, which is beneficial to enhancing the structural strength and durability of the fixed sleeve 53 on the one hand, so that when the elastic plug-in column 54 is inserted into the fixed sleeve 53, the fixed sleeve 53 is not easily deformed, so that the upper braces 1 and the lower braces 2 are not easily deformed, thereby facilitating the upper braces 1 and the lower braces 2 to achieve the correction effect stably and accurately; on the other hand, it can also ensure a stable interference fit between the elastic plug-in column 54 and the fixed sleeve 53, which is beneficial to improving the connection stability between the upper occlusal plate 3 and the upper braces 1, and improving the connection stability between the lower occlusal plate 4 and the lower braces 2, further ensuring the correction effect.

[0057] Reference Figure 4A first magnetic plate 531 is mounted within the fixed sleeve 53, and reinforcing ribs 541 are embedded within the elastic plug-in column 54 along its length. In this embodiment, the reinforcing ribs 541 are made of a metal material that can be attracted by the first magnetic plate 531. Therefore, when the elastic plug-in column 54 is inserted into the fixed sleeve 53, the first magnetic plate 531 can generate an attractive force on the reinforcing ribs 541, thereby strengthening the connection between the upper and lower bite plates 3 and 4 and the upper and lower braces 1 and 2. Furthermore, the reinforcing ribs 541 have a certain structural strength, making the elastic plug-in column 54 less likely to bend, thereby facilitating the use of the elastic plug-in column 54 to stably support the upper and lower bite plates 3 and 4.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
