[0002] Orthodontics is the process of correcting teeth and eliminating malocclusions and deformities. Orthodontics mainly studies the etiology, diagnosis and analysis of malocclusion, as well as its prevention and treatment. It can correct problems such as uneven teeth and incorrect bites, thereby achieving the effect of beautiful teeth.

[0003] The existing orthodontic structure is generally composed of a metal sheet, a guide ring and a steel wire. The metal sheet is bonded to the teeth, and the guide ring is used to guide the steel wire so that the steel wire can pull the misaligned teeth to move. Through regular adjustment, the purpose of correction is achieved. This method has been used to this day. According to an in-depth study of the prior art, the applicant found that the guide ring exposed to the outside and the openings on the surface, as well as the winding connection between the tail end steel wire and the guide ring will affect the user's comfort. The fine wires on the surface will scrape and rub the skin.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 8 , the present invention provides a technical solution: a novel oral tooth orthodontic structure, comprising at least three U-shaped blocks 1, an adjustment component is installed on the inner side of the U-shaped block 1, a separation component is installed on the outer side of the U-shaped block 1, and a shielding component for shielding the adjustment component is installed on the outer side of the U-shaped block 1;

[0036] In the above embodiment, by using the shielding component, the connection point of the steel wire end and the guide structure can be shielded and concealed, which greatly improves the wearing comfort and convenience of use. A hole-free installation design is used on the outer shielding structure to avoid opening holes as much as possible, thereby reducing food residues while increasing wearing comfort, allowing users to wear correction more comfortably. By using the separation component, a single guide adjustment structure can be removed and replaced without completely removing the steel wire, thereby increasing the convenience of the replacement process, and there is no need to adjust other orthodontic structural components away from the location, reducing the workload of related operators. At the same time, under the action of the adjustment component, additional pulling force can be applied to a displaced tooth, so that the correction force can act more directly on the corresponding tooth, which is beneficial to improving the effectiveness of orthodontics.

[0037] In this embodiment, the separation assembly is a structure used to separate the U-shaped block 1 and the middle plate 301 to facilitate replacement.

[0038] like Figure 4 , Figure 5 and Figure 6 As shown, the separation component includes an intermediate plate 301 abutting against the left side of the U-shaped block 1, an adhesive layer 302 bonded to the left side of the intermediate plate 301, a removal hole 303 opened on the left side of the U-shaped block 1 and connected to the interior thereof, a connecting hole 304 opened on the left side of the annular guide 201 and connected to the interior thereof, four plug-in rods 305 fixed to the right side of the intermediate plate 301, a first elastic member 306 fixed to the outside of the plug-in rods 305, four plug-in grooves 307 opened on the left side of the U-shaped block 1 and respectively provided for sliding cooperation of the four plug-in rods 305 and the corresponding first elastic member 306, four limiting oblique cavities 308 opened inside the U-shaped block 1, four plug-in cavities 309 opened inside the U-shaped block 1, a plug-in plate 310 fixed on the right side of the intermediate plate 301, and two inclined grooves 311 opened on the front and back sides of the U-shaped block 1, respectively.

[0039] It should be noted that the interior of the connecting hole 304 is connected to the interior of the removal hole 303, and the front and back sides of the removal hole 303 and the connecting hole 304 are both open, so that the orthodontic wire 202 can be normally moved out to the outside through the connecting hole 304 and the removal hole 303, and the bonding layer 302 is a non-toxic adhesive such as medical adhesive glue.

[0040] In addition, the interiors of the limiting oblique cavity 308 and the plug-in cavity 309 are both connected to the interiors of the corresponding plug-in grooves 307. The limiting oblique cavity 308 is for the corresponding first elastic member 306 to be plugged in, and the plug-in cavity 309 is for the corresponding end of the plug-in rod 305 to be plugged in, wherein the plug-in cavity 309 and the end of the plug-in rod 305 are transitionally matched, so that the plug-in rod 305 has a certain pulling force after being plugged into the inner side of the corresponding plug-in cavity 309, and a certain force needs to be applied during the insertion and removal process, so as to cooperate with the use of the limiting oblique cavity 308 and the first elastic member 306 to position the plug-in rod 305. The first elastic member 306 can be a plastic member of medical standard, which is convenient for elastic deformation. The limiting oblique cavity 308 is triangular, and through the setting of the inclined surface, it can have a certain limiting ability while being directly pulled out.

[0041] At the same time, the plug-in plate 310 is plugged into the inner side of the corresponding removal hole 303, and the right side of the plug-in plate 310 and the inner left side wall of the U-shaped block 1 are located in the same longitudinal horizontal plane, so that the plug-in plate 310 can block the removal hole 303, thereby providing support for the orthodontic wire 202, and preventing food residues from accumulating inside the removal hole 303. The inclined groove 311 is located in the middle of the corresponding U-shaped block 1, and the interior of the inclined groove 311 is connected to the interior of the removal hole 303. By snapping the two inclined grooves 311 with your fingers, it is convenient to pull the U-shaped block 1 to separate it from the middle plate 301, and you can also use a special tool that can be inserted into the two inclined grooves 311 at the same time to help snap together, making it more convenient to apply force.

[0042] In this embodiment, the adjustment component is a structure for adjusting the tension of the orthodontic wire 202 .

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, the adjustment component includes two annular guides 201 fixed to the inner left side wall of the U-shaped block 1, an orthodontic wire 202 inserted between the inner sides of the corresponding several annular guides 201, an adjustment box 203 fixed to the inner bottom wall of the U-shaped block 1, two guide rods 204 fixed to the top of the adjustment box 203, a screw 205 rotatably connected to the inner bottom wall of the adjustment box 203 through a bearing, an adjustment block 206 threadedly connected to the outer side of the screw 205, and a T-shaped hole 211 opened on the front side of the adjustment block 206; the adjustment component also includes a worm gear 207 fixedly mounted on the outer side of the screw 205, a worm 208 rotatably connected to the inner side of the adjustment box 203 through a bearing, an inner hexagonal piece 209 fixed to the right end of the worm 208, and a limit plate 210 fixedly mounted on the inner left side wall of the U-shaped block 1.

[0044] It should be noted that the outer side of the worm wheel 207 and the outer side of the corresponding worm 208 are meshed with each other, and a rotation groove for the hexagonal piece 209 to be inserted and rotated is opened on the right side of the adjustment box 203, so that the hexagonal piece 209 can be rotated on the inner side of the rotation groove, so as to facilitate the transmission of the worm wheel 207 through the worm 208, and the bottom of the limit plate 210 can abut against the top of the corresponding adjustment block 206, and the left side of the T-shaped hole 211 is open, and the left side of the adjustment block 206 is in contact with the inner left wall of the U-shaped block 1. Specifically, when the bottom of the limit plate 210 abuts against the top of the adjustment block 206, the left opening of the T-shaped hole 211 can be connected to the inside of the removal hole 303, so that the orthodontic wire 202 can be removed.

[0045] In addition, the orthodontic wire 202 is passed through the inner side of the corresponding annular guide 201 and the T-shaped hole 211, and the two tail ends of the orthodontic wire 202 are respectively wrapped and connected with the two outermost annular guides 201, so as to tighten the orthodontic wire 202 to apply tension to the teeth. The top end of the guide rod 204 passes through the bottom of the corresponding adjustment block 206, and the top end of the screw 205 passes through the top of the corresponding adjustment box 203, so that the guide rod 204 can limit the adjustment block 206, and then adjust and move the adjustment block 206 through the screw 205. The top ends of the screw 205 and the guide rod 204 are located in the same horizontal plane and are both located below the removal hole 303, so that the orthodontic wire 202 can be moved out from the inner side of the removal hole 303 without being restricted by the screw 205 or the guide rod 204.

[0046] In this embodiment, the shielding component is used to shield the internal structure of the U-shaped block 1 so that the complex adjustment structure is not easy to rub against the skin tissue inside the oral cavity.

[0047] like Figure 1 , Figure 7 and Figure 8 As shown, the shielding assembly includes two docking grooves 401 opened on the right side of the U-shaped block 1 and symmetrically distributed up and down, a docking plate 402 abutting between the inner sides of the two corresponding docking grooves 401, two closing plates 403 fixed to the left side of the docking plate 402, a placement groove 404 opened on the front side of the closing plate 403 and opened on the left side, four movable holes 405 opened on the right side of the docking plate 402, an arc-shaped spring piece 406 fixed to the inner side of the movable hole 405 and bent to the right side, a fixing rod 407 fixed to the left side of the arc-shaped spring piece 406, a push plate 408 fixed to the outer side of the fixing rod 407, and a double A protrusion 409, a single protrusion 410 fixed to the left end of the fixing rod 407, four engaging grooves 411 opened on the right side of the U-shaped block 1 and corresponding to the positions of the four movable holes 405 respectively, a spring 412 fixed to the left side wall of the engaging groove 411, a telescopic rod 413 fixedly installed on the left side wall of the engaging groove 411, an abutment plate 414 fixed to the right side of the spring 412, a second elastic member 415 fixedly installed on the inner top wall and the inner bottom wall of the engaging groove 411 respectively, a plurality of arc-shaped silicone blocks 416 fixed to the outside of the second elastic member 415, and a trapezoidal block 417 fixed to the second elastic member 415 on the side close to the corresponding fixing rod 407.

[0048] It should be noted that the front and back sides of the docking groove 401 are both open, and the docking groove 401 is connected to the inner side of the U-shaped block 1, so that the docking plate 402 can be inserted between the inner sides of the two docking grooves 401 to cover the right side opening of the U-shaped block 1, and the closing plate 403 is inserted into the inner side of the U-shaped block 1, and the placement groove 404 is for the orthodontic wire 202 to be inserted, so that the closing plate 403 can cover the front and back openings of the U-shaped block 1, and retain the opening for the orthodontic wire 202 to pass normally, so that the orthodontic wire 202 can be bound normally.

[0049] In addition, the double protrusion 409 is located between the corresponding single protrusion 410 and the opposite side of the push plate 408, so that the double protrusion 409 can be pushed by the single protrusion 410 or the push plate 408. The diameter of the double protrusion 409 is larger than the diameter of the single protrusion 410, and the left side of the single protrusion 410 is arc-shaped, so that the double protrusion 409 can push the trapezoidal block 417 to move. The telescopic rod 413 is located on the inner side of the corresponding spring 412, and the right end of the telescopic rod 413 is fixedly connected to the left side of the corresponding abutment plate 414, so that the abutment plate 414 can elastically abut the single protrusion 410 under the cooperation between the spring 412 and the telescopic rod 413.

[0050] At the same time, the second elastic member 415 is composed of a square plate and an L-shaped plastic member, and the arc-shaped silicone block 416 is bonded to the bending part of the L-shaped plastic member and the right side of the connection between the square plate and the L-shaped plastic member, so that the second elastic member 415 can undergo a certain elastic deformation, and the elastic stability is improved under the elastic cooperation of the arc-shaped silicone block 416, so that it can be suitable for the engagement action of the trapezoidal block 417 on the single protrusion 410, and the right side of the trapezoidal block 417 is arc-shaped, so that it can be pushed by the single protrusion 410 and the double protrusion 409, wherein the elastic force of the spring 412 is much greater than the sum of the elastic forces of the second elastic member 415 and the corresponding arc-shaped silicone block 416, so that the spring 412 can normally push the single protrusion 410 from the bottom of the trapezoidal block 417 to the right side.

[0051] The working principle of the above embodiment is:

[0052] (1) When performing orthodontic treatment on teeth, at least three U-shaped blocks 1 are bonded to the teeth through the bonding layer 302, the orthodontic wire 202 is passed through the corresponding annular guide 201 and the inner side of the T-shaped hole 211, and the two ends of the orthodontic wire 202 are respectively bound to the outer sides of the two outermost annular guides 201, and the orthodontic wire 202 needs to be kept in a taut state so as to apply pressure to correct the offset teeth. When the offset of individual teeth is too serious, the worm 208 can be driven to rotate by rotating the hexagonal piece 209, thereby rotating the worm wheel 207 and rotating the screw 205. Under the limiting and guiding action of the corresponding two guide rods 204, the adjustment block 206 can move downward, thereby applying additional pulling force to the adjacent teeth, thereby playing an auxiliary pressure correction effect and facilitating the doctor to adjust.

[0053] (2) After the adjustment is completed, the inner structure of the U-shaped block 1 needs to be shielded, the docking plate 402 is moved to the inner side of the docking groove 401, and the closing plate 403 is moved to the front and rear openings of the inner side of the U-shaped block 1, and then the opening of the U-shaped block 1 is shielded by the docking plate 402 and the closing plate 403, so that the internal structure will not rub against the oral skin and cause discomfort, and the docking plate 402 is continued to be pressed so that the single protrusion 410 enters the inner side of the corresponding engaging groove 411, and the single protrusion 410 can push the corresponding two ladders The trapezoidal block 417 moves to the side away from the other side, and drives the second elastic member 415 to deform under the auxiliary elastic cooperation of the corresponding arc-shaped silicone block 416, so that the trapezoidal block 417 moves between the corresponding single protrusion 410 and the opposite side of the double protrusion 409. The pressure applied to the single protrusion 410 by the spring 412 and the abutment plate 414 can help the single protrusion 410 to limit the position, so that the docking plate 402 and the closing plate 403 can have a good shielding effect on the inner structure of the U-shaped block 1, so that the tongue, etc. The friction discomfort when the oral tissue is licked can be greatly reduced. When it is necessary to remove it, the fixing rod 407 is pressed by the arc-shaped spring piece 406, so that the push plate 408 and the single protrusion 410 move together, and the trapezoidal block 417 blocks and limits the double protrusion 409, so that the double protrusion 409 is pushed over the trapezoidal block 417 under the pushing action of the push plate 408. At this time, the trapezoidal block 417 is located at the right side of the top of the double protrusion 409, and under the cooperation of the second elastic member 415 and the corresponding arc-shaped silicone block 416 The trapezoidal block 417 will apply a force to the double protrusion 409 to move to the left, so that the double protrusion 409 and the single protrusion 410 are fitted together, and the spring 412 is in a compressed state. Under the elastic recovery action of the spring 412, the single protrusion 410 is pushed to move to the side away from the U-shaped block 1 through the abutment plate 414, and then the double protrusion 409 is pushed to cross the trapezoidal block 417 together through the single protrusion 410, so as to achieve the effect of contact limiting, and the docking plate 402 can be taken out normally to adjust the orthodontic wire 202 inside the U-shaped block 1.

[0054] (3) When the U-shaped block 1 or other structures are damaged during long-term wearing, the hexagonal piece 209 is rotated, and according to the above principle, the screw 205 drives the adjustment block 206 to move so that it abuts against the bottom of the limit plate 210. At this time, the inside of the T-shaped hole 211 and the inside of the removal hole 303 are connected, and the U-shaped block 1 can be snapped and pinched through the corresponding two inclined grooves 311, and the U-shaped block 1 can be directly pulled, so that the orthodontic wire 202 is moved out of the removal hole 303 to the outside, and the first elastic member 306 is deformed and moves from the corresponding limit inclined groove. The inner side of the cavity 308 is moved out to complete the removal of the entire U-shaped block 1. When it needs to be installed, align the orthodontic wire 202 with the removal hole 303, so that it passes through the removal hole 303 and the connecting hole 304 to enter between the corresponding T-shaped hole 211 and the inner side of the annular guide 201, and press the U-shaped block 1 to make the connecting rod 305 plug into the inner side of the corresponding connecting cavity 309, and let the first elastic member 306 elastically snap into the inner side of the corresponding limiting inclined cavity 308 to complete the limiting. The orthodontic wire 202 can be readjusted by rotating the hexagonal member 209 to complete the replacement.

[0055] Compared with the prior art, the novel oral orthodontic structure can conceal the connection of the steel wire end and the guide structure by using a shielding component, which greatly improves the wearing comfort and convenience of use. A hole-free installation design is used on the outer shielding structure to avoid opening holes as much as possible, thereby reducing food residues while increasing wearing comfort, allowing users to wear correction more comfortably. By using a separation component, a single guide adjustment structure can be removed and replaced without completely removing the steel wire, thereby increasing the convenience of the replacement process, and there is no need to adjust other orthodontic structural components away from the location, reducing the workload of relevant operators. At the same time, under the action of the adjustment component, additional pulling force can be applied to a displaced tooth, so that the correction force can act more directly on the corresponding tooth, which is conducive to improving the effectiveness of orthodontics and solves the problem that the oral orthodontic structure is not comfortable during actual wearing and a single guide structure is inconvenient to replace when it is damaged.
