Description

Technical Field

[0001] This invention relates to the field of orthodontic auxiliary tools, and in particular to a positioning bracket assembly for assisting bracket bonding. Background Technology

[0002] Currently, there are two main methods for bonding brackets to a patient's teeth: direct bonding and indirect bonding. Direct bonding involves attaching each bracket individually to the tooth surface using glue; this method is less efficient. Indirect bonding involves using auxiliary tools to bond the brackets to the tooth surface. These tools ensure proper placement of the brackets and are more efficient. For example, a positioning bracket assembly is one such auxiliary tool.

[0003] Traditional positioning bracket assemblies used to assist in bracket bonding typically consist of multiple integrally molded occlusal plates and multiple positioning blocks. The occlusal plates mate with the occlusal surfaces of the teeth, with each plate completely covering the occlusal surface. The positioning blocks mate with the brackets, with each block fully or mostly covering the bracket. This structure has the following disadvantages: ① Material waste; ② High printing precision is required when manufacturing the positioning bracket assemblies using 3D printing, leading to high costs; ③ Full or partial coverage of the bracket by the positioning blocks affects the observation of excess adhesive on the bracket base plate, making it difficult to scrape off the overflowing adhesive. Summary of the Invention

[0004] Therefore, it is necessary to provide a positioning bracket assembly for assisting in the bonding of brackets, which can effectively reduce material waste, lower costs, and facilitate the removal of excess adhesive, in order to address the aforementioned technical problems.

[0005] A positioning bracket assembly for assisting bracket bonding includes a bracket body, multiple positioning blocks, and multiple tilt markers. The bracket body is used to mate with the tooth surface. The positioning blocks are fixedly mounted on the bracket body and have mounting slots. The tilt markers include rod-shaped scale markings with multiple spaced scale markings. Each scale marking has a suspended first end, which is detachably assembled into the mounting slot and mates with the slot for installation.

[0006] In one embodiment, the mounting groove is formed on the lip side of the positioning block and extends through the gingival direction of the positioning block. A slot is provided on the side wall of the mounting groove, and the scale mark cooperates with the slot to achieve installation.

A slot is provided on the side wall of the mounting groove, and a buckle is formed by the first end of the scale marking portion protruding towards one side of the mounting groove. The buckle cooperates with the slot.

[0008] In one embodiment, the mounting groove is formed on the lip side of the positioning block and extends through the gingival direction of the positioning block. An insertion hole is formed in the mounting groove, and the first end of the scale marking portion is inserted into the insertion hole.

[0009] In one embodiment, the mounting groove is formed on the lip side of the positioning block and extends through the gingival direction of the positioning block. The positioning block is provided with a first through hole and the scale marking part is provided with a second through hole. The scale marking part is assembled with the positioning block by inserting a pin into the first through hole and the second through hole.

[0010] In one embodiment, the mounting groove is formed on the near-center or far-center side of the positioning block, the sidewall of the mounting groove is provided with a boss slide rail, and the first end of the scale marking part is provided with a slide groove that cooperates with the boss slide rail.

[0011] In one embodiment, the mounting groove is formed on the near-center or far-center side of the positioning block, the side wall of the mounting groove is provided with a sliding groove, and the first end of the scale marking part is provided with a boss slide rail that cooperates with the sliding groove.

[0012] In one embodiment, the support body includes a connecting rod and a plurality of engagement plates, wherein the connecting rod, engagement plates and positioning blocks are integrally formed.

[0013] In one embodiment, the support body includes a plurality of integrally formed occlusal plates, each occlusal plate being fixedly connected, and the positioning block being fixed to the occlusal plates.

[0014] The main body of the bracket includes an integrally formed bite plate, and the positioning block is fixed to the bite plate.

[0015] In one embodiment, the scale markings include a first scale marking located at a first end, a second scale marking adjacent to the first scale marking, and a plurality of spaced third scale markings adjacent to the second scale marking, wherein the lengths of the first scale marking, the second scale marking, and the third scale markings are not equal.

[0016] In one embodiment, the tilt indicator further includes a plate-shaped main body, a positioning part, and a clamping part. The plate-shaped main body has a first surface and a second surface disposed opposite to the first surface. The positioning part is located on the first surface and is used to be inserted into the archwire groove of the bracket. The clamping part is located on the second surface and protrudes from the second surface. The first end of the scale marking part is suspended, and the second end of the scale marking part is disposed on the plate-shaped main body.

[0017] In one embodiment, the clamping portion is a rib protruding from the second surface, the rib extending along the axial tilt direction.

[0018] In one embodiment, the height of the rib protruding from the second surface ranges from 0.2mm to 1.2mm.

[0019] In one embodiment, the rib has a pressing groove.

[0020] In one embodiment, the plate-shaped main body has a notch on its proximal and / or distal sides, or the proximal side of the main body has a protrusion in the proximal direction and / or the distal side of the main body has a protrusion in the distal direction.

[0021] In one embodiment, the first surface of the plate-shaped main body is provided with an elastic locking portion, and there is a gap between the elastic locking portion and the positioning portion.

[0022] In one embodiment, the clamping part and the scale marking part are spaced apart from each other; or the clamping part and the scale marking part are integrally formed.

[0023] In one embodiment, the plate-shaped main body is generally square, and the gingival surface of the plate-shaped main body has a pointed tip structure that protrudes toward the gingiva.

[0024] In one embodiment, the lip side of the clamping part is provided with an arrow pointing indicator.

[0025] In one embodiment, the second surface of the plate-shaped main body is provided with tooth position markings.

[0026] In one embodiment, the second surface of the plate-shaped main body is provided with a groove position line, which is parallel to the bowwire groove.

[0027] The positioning bracket assembly described above for assisting in bracket bonding has at least the following advantages:

[0028] First, compared with the positioning blocks in the prior art that need to fully or mostly cover the tray, the positioning block in this application has a simpler structure and smaller size, thus effectively saving materials.

[0029] Secondly, the mounting slot on the positioning block and the first end of the scale marking part of the tilt indicator are detachably fitted, allowing the tilt indicator to be flexibly selected, replaced, or reused according to the actual tooth position and bracket model. The tilt indicator can be manufactured relatively independently from the bracket body and the positioning block. This modular design avoids the overall scrap caused by the poor adaptability of traditional integrated positioning devices, significantly reduces the material consumption and waste of high-precision positioning indicator components, and also lowers the printing accuracy requirements, effectively reducing costs.

[0030] This component achieves rapid and accurate bracket positioning through precise matching between the bracket body and the tooth surface, and the pre-set mounting slots on the positioning block. Doctors no longer need to repeatedly adjust the bracket position inside the mouth, nor rely on additional measuring tools to determine the bracket's tilt angle, greatly simplifying the procedure, shortening clinical operation time, and significantly improving treatment efficiency. The clear graduations on the tilt marker provide doctors with an intuitive and precise angle reference, ensuring the accuracy of the bracket bonding angle, reducing rework due to angle deviations, and further guaranteeing treatment efficiency and quality.

[0031] Finally, a mounting slot is provided on the positioning block, and the first end of the scale marking part of the tilt indicator is suspended and detachably assembled into the mounting slot. The rod-shaped scale marking part forms a clearly defined, operable space on both sides. During bracket bonding, when adhesive overflows between the bracket base and the tooth, this space provides a clear operating path and point of application for the dentist to use scaling tools (such as probes or specialized scrapers). The dentist can more easily and precisely scrape away excess adhesive without worrying about interference between the tool and the complex one-piece structure. Attached Figure Description

[0053] Unless otherwise stated, the following structural description requires the use of the maxillary teeth as a reference frame to describe embodiments of the invention. Therefore, as used herein, terms such as labial, lingual, mesial, distal, occlusal, and gingival, used to describe brackets, are relative to the selected reference frame. However, embodiments of the invention are not limited to the selected reference frame and the terms described, as brackets can be used on other teeth in the oral cavity and in other directions.

[0054] The terms labial, lingual, mesial, distal, occlusal, and gingival are industry terms used in orthodontic treatment. Taking an upper jaw tooth as an example, the tooth surface can be roughly divided into six surfaces. The surface of the tooth that occludes with the lower jaw teeth is the occlusal surface; the surface of the tooth that connects to the attached gingival tissue is the gingival surface; the occlusal surface and the gingival surface are opposite each other, and the direction formed by the occlusal surface and the gingival surface is also called the gingio-occlusal direction. The surface of the tooth facing the lips is the labial surface, and the surface of the tooth facing the tongue is the lingual surface; the labial surface and the lingual surface are opposite each other, and the direction formed by the labial surface and the lingual surface is also called the labiolingual direction. The two surfaces of the tooth that contact adjacent teeth are the mesial surface and the distal surface, the difference being their distance from the center; the direction formed by the two is also called the mesiodistal direction, or mesiodistal direction.

[0055] Furthermore, in the description of direction, "lip-tongue direction" generally refers to two directions. However, "lip-tongue direction" specifically refers to a single direction, that is, from the side of the lips to the side of the tongue, and this is used to distinguish them.

[0056] Please see Figures 1 to 8In one embodiment, a positioning bracket assembly 10 for assisting bracket bonding includes a bracket body 100, multiple positioning blocks 200, and multiple tilt markers 300. The bracket body 100 is used to mate with the surface of the tooth 20. The positioning blocks 200 are fixedly disposed on the bracket body 100 and have mounting grooves 210. The tilt markers 300 include rod-shaped scale marking portions 310, which have multiple spaced scale markings. Each scale marking portion 310 has a suspended first end 301. The first end 301 of the scale marking portion 310 is detachably assembled into the mounting groove 210 and mates with the mounting groove 210 to achieve installation.

[0057] Please see Figure 5 and Figure 6 Specifically, in this embodiment, the support body 100 includes a connecting rod 110 and multiple occlusal plates 120, which are integrally formed. For example, the support body 100 can be formed by 3D printing. The connecting rod 110 is mainly used to connect the occlusal plates 120 and the positioning blocks 200. The occlusal plates 120 are mainly used to mate with the occlusal surfaces of the teeth 20, and the positioning blocks 200 are mainly used to mate with the scale markings 310. In the figure, the number of occlusal plates 120 is less than the number of teeth 20. Of course, in other embodiments, the support body 100 may not include the connecting rod 110, but may include multiple integrally formed occlusal plates 120, with each occlusal plate 120 fixedly connected, one occlusal plate 120 corresponding to the occlusal surface of one tooth 20, and the positioning blocks 200 fixed to the occlusal plates 120. Alternatively, the support body 100 may include an integrally formed occlusal plate 120, with positioning blocks 200 fixed to the occlusal plate 120, which can correspond to the occlusal surfaces of all teeth 20, or most of the occlusal surfaces of teeth 20.

[0058] Please see Figures 7 to 10The mounting groove 210 is formed on the labial side of the positioning block 200 and extends through the gingival direction of the positioning block 200. A slot 211 is provided on the side wall of the mounting groove 210, and the scale markings cooperate with the slot 211 to achieve installation. Specifically, in this embodiment, the scale marking part 310 is provided with multiple spaced scale markings, including a first scale marking 311 located at the first end 301, a second scale marking 312 adjacent to the first scale marking 311, and multiple spaced third scale markings 313 adjacent to the second scale marking 312. The lengths of the first scale marking 311, the second scale marking 312, and the third scale marking 313 are not equal. Therefore, it can meet the needs of different tooth sizes 20 at different ages, making it convenient for doctors to determine whether the bracket is properly bonded. For example, when the bracket needs to be bonded to the surface of an adult tooth 20, it is determined whether the first scale marking 311 is flush with the incisal edge of the tooth 20. If it is flush, it indicates that the bracket has been properly bonded to the adult tooth 20. When the bracket needs to be bonded to the surface of the adolescent's tooth 20, it is determined whether the second scale mark 312 is flush with the incisal edge of the tooth 20. If it is flush, it means that the bracket has been bonded to the adolescent's tooth 20.

[0059] Please see Figure 7 and Figure 8 In this embodiment, the first scale mark 311 located at the first end 301 is longer than the other scale marks. The first scale mark 311 cooperates with the slot 211 on the side wall of the mounting groove 210 to prevent the tilt mark 300 from moving or dislodging in the mesiodistal direction and the gingival direction.

[0060] Please see Figure 11 and Figure 12 In the illustrated embodiment, the mounting groove 210 is formed on the lip side of the positioning block 200 and extends through the gingival direction of the positioning block 200. A slot 211 is provided on the side wall of the mounting groove 210. A buckle 314 protrudes from the first end 301 of the scale marking portion 310 towards one side of the mounting groove 210, and the buckle 314 engages with the slot 211. Two buckles 314 are spaced apart and opposite each other, and each buckle 314 has a certain degree of elasticity. The buckle 314 engages with the mounting groove 210 from the lip side of the positioning block 200 and is secured within the slot 211, preventing the tilt indicator 300 from detaching from the positioning block 200.

[0061] Please see Figure 13 and Figure 14In the illustrated embodiment, the mounting groove 210 is formed on the lip side of the positioning block 200, and the mounting groove 210 penetrates the gingival direction of the positioning block 200. An insertion hole 315 is formed in the mounting groove 210, and the first end 301 of the scale marking part 310 is inserted into the insertion hole 315. The first end 301 of the scale marking part 310 is inserted into the insertion hole 315 from the gingival direction of the mounting groove 210, thereby realizing the assembly of the tilt indicator rod with the positioning block 200.

[0062] Please see Figure 15 In the illustrated embodiment, the mounting groove 210 is formed on the lip side of the positioning block 200 and extends through the gingival direction of the positioning block 200. The positioning block 200 is provided with a first through hole 220, and the scale marking part 310 is provided with a second through hole 320. The scale marking part 310 is assembled with the positioning block 200 by inserting a pin 230 into the first through hole 220 and the second through hole 320. Specifically, the pin 230 is generally a plate-shaped structure, such as a flat plate or an arc-shaped plate. The pin 230 is inserted into the first through hole 220 and the second through hole 320 to realize the assembly of the tilt marking part 300 with the positioning block 200.

[0063] Please see Figure 16 and Figure 17 In the illustrated embodiment, the mounting groove 210 is formed on the near-center or far-center side of the positioning block 200. A boss slide rail 240 is provided on the sidewall of the mounting groove 210, and the first end 301 of the scale marking portion 310 is provided with a sliding groove 316 that mates with the boss slide rail 240. In other embodiments, the mounting groove 210 is formed on the near-center or far-center side of the positioning block 200, and a sliding groove 316 is provided on the sidewall of the mounting groove 210. The first end 301 of the scale marking portion 310 slides into the positioning block 200 from the near-center or far-center side, thus assembling the tilt marker 300 with the positioning block 200.

[0064] Please see Figures 7 to 10In one embodiment, the tilt indicator 300 is generally pre-installed on the spherical self-locking bracket 30. Specifically, the tilt indicator 300 further includes a plate-shaped main body 330, a positioning part 340, and a clamping part 350. The plate-shaped main body 330 has a first surface 331 and a second surface 332 disposed opposite to the first surface 331. The plate-shaped main body 330 has a plate-shaped structure. For example, the plate shape includes not only planar plates but also curved plates. More specifically, when the plate-shaped main body 330 is planar, both the first surface 331 and the second surface 332 are planar. When the plate-shaped main body 330 is curved, the first surface 331 can be curved, and the second surface 332 can also be curved. Alternatively, one side of the first surface 331 and the second surface 332 may be curved, while the other side may be planar.

[0065] Specifically, in this embodiment, the plate-shaped main body 330 is generally square, and the gingival surface of the plate-shaped main body 330 has a pointed structure protruding towards the gingiva. Correspondingly, the base plate is also generally square, and the gingival surface of the base plate also has a pointed structure protruding towards the gingiva. This structural design facilitates the positioning of the bracket when it is bonded to the surface of the tooth 20. The second surface 332 of the plate-shaped main body 330 is provided with a tooth position marker 333 to facilitate quick identification of the corresponding tooth position by the dentist. The second surface 332 of the plate-shaped main body 330 is provided with a groove position line 334, which is parallel to the archwire groove. This facilitates quick alignment with the archwire groove when assembled onto the bracket.

[0066] Specifically, in this embodiment, the positioning part 340 is located on the first surface 331 and is used to be inserted into the archwire groove of the bracket. Specifically, the positioning part 340 is also generally plate-shaped to match the shape of the archwire groove and can be inserted into the archwire groove. In addition, the positioning part 340 also ensures that the tilt marker 300 does not move in the gingival direction after it is installed on the bracket.

[0067] Specifically, in this embodiment, a notch 335 is provided on the proximal and / or distal side of the plate-shaped main body 330. The purpose of providing the notch 335 is to expose part of the archwire groove, making it easier for the positioning part 340 to be installed into the archwire groove more quickly. For example, in this embodiment, the notch 335 is provided on both the proximal and distal sides of the plate-shaped main body 330. Of course, in other embodiments, the notch 335 may be provided only on the proximal side of the plate-shaped main body 330, or only on the distal side of the plate-shaped main body 330.

[0068] Specifically, in this embodiment, the first surface 331 of the plate-shaped main body 330 is provided with an elastic locking part 336, and there is a gap between the elastic locking part 336 and the positioning part 340. The elastic locking part 336 has a certain elasticity. When the tilt indicator 300 is assembled onto the bracket, the elastic locking part 336 is locked in the opening groove and deforms. Therefore, the tilt indicator 300 can be kept from moving in the lip direction and the mesiodistal direction.

[0069] The clamping portion 350 is located on and protrudes from the second surface 332, and is mainly used for clamping tools such as tweezers. Specifically, the clamping portion 350 can be a rib protruding from the second surface 332, extending along the axial direction. Therefore, the clamping portion 350 and the plate-shaped main body 330 can be integrally formed. For example, the plate-shaped main body 330 and the clamping portion 350 can be manufactured by 3D printing. Of course, in other embodiments, the clamping portion 350 can also be other structures, as long as it can achieve the purpose of clamping with tweezers. For example, the clamping portion 350 can be a protrusion protruding from the second surface 332, etc.

[0070] Specifically, in this embodiment, the lip side of the clamping part 350 is provided with an arrow pointing mark 351, which is mainly used for pointing and alignment, making it convenient for doctors to operate.

[0071] Specifically, in this embodiment, the height of the rib protruding from the second surface 332 ranges from 0.2mm to 1.2mm. If the height of the rib protruding from the second surface 332 is less than 0.2mm, the gripping effect of the tweezers will be poor, which is not conducive to a firm grip. If the height of the rib protruding from the second surface 332 is greater than 1.2mm, it is unsightly and wastes material. For example, the height range of the rib protruding from the second surface 332 can be any group of 0.3mm-0.7mm, 0.4mm-0.8mm, 0.5mm-0.9mm, 0.6mm-1.0mm, 0.7mm-1.1mm, or 0.8mm-1.2mm.

[0072] Specifically, in this embodiment, a pressing groove 352 is provided on the rib. The pressing groove 352 is mainly used to apply pressure to tools such as probes to squeeze out excess glue from the base plate. The pressing groove 352 extends in the proximal-distal direction and can be approximately parallel to the direction of the archwire groove. The number of pressing grooves 352 is not limited and can be one, two, or more.

[0073] Specifically, in this embodiment, the scale marking portion 310 is rod-shaped, with its first end 301 suspended and its second end 317 disposed on the plate-shaped main body portion 330. For example, the clamping portion 350 and the scale marking portion 310 are integrally formed and can be manufactured by 3D printing. When the clamping portion 350 and the scale marking portion 310 are integrally formed, there is no need to distinguish the boundary between the clamping portion 350 and the scale marking portion 310; anything that can perform the clamping function can be used as the clamping portion 350, and anything that can perform the scale marking function can be used as the scale marking portion 310. Furthermore, both the clamping portion 350 and the scale marking portion 310 extend along the axial tilt direction. Of course, in other embodiments, the clamping portion 350 and the scale marking portion 310 can also be arranged at intervals.

[0074] The tilt indicator 300 is generally pre-installed on the spherical self-locking bracket 30. Specifically, it is inserted into the bow wire groove of the spherical self-locking bracket 30 through the positioning part 340. The plate-shaped main body part 330 is located outside the cover and the first end 301 of the main body of the spherical self-locking bracket 30. The clamping part 350 and the scale marking part 310 are both extended along the tilt line direction of the spherical self-locking bracket 30. When the spherical self-ligating bracket 30 with the tilt indicator 300 needs to be glued to the surface of the tooth 20, it can be held in place by tweezers on the clamping part 350 to grasp and glue the entire spherical self-ligating bracket 30 with the tilt indicator 300 to the surface of the tooth 20. The angle or position of the bracket can also be adjusted by clamping the clamping part 350. The plate-shaped main body 330 is beneficial for positioning the bracket during bonding. Compared with the spherical shape of the bracket, the plate-shaped main body 330 is more square and better at adjusting the tilt angle. The rod-shaped scale mark part 310 is used to determine whether the bonding position on the tooth surface is appropriate. Therefore, the tilt indicator 300, as an auxiliary tool, solves the disadvantages of the spherical self-ligating bracket 30 being difficult to grasp and position due to its spherical shape, and improves the bonding efficiency and accuracy of the spherical self-ligating bracket 30.

[0075] The positioning bracket assembly 10 for assisting in bracket bonding described above has at least the following advantages:

[0076] First, compared with the positioning block 200 in the prior art that needs to fully or mostly cover the tray, the positioning block 200 in this application has a simpler structure and smaller size, thus effectively saving materials.

[0077] Secondly, the mounting groove 210 on the positioning block 200 and the first end 301 of the scale marking portion 310 of the tilt marking component 300 are detachably fitted together, allowing the tilt marking component 300 to be flexibly selected, replaced, or reused according to the actual tooth position and bracket model. The tilt marking component 300 can be manufactured relatively independently from the bracket body 100 and the positioning block 200. This modular design avoids the overall scrapping caused by poor adaptability of traditional integrated positioning devices, significantly reduces the material consumption and waste of high-precision positioning marking components, and also lowers the printing accuracy requirements, effectively reducing costs.

[0078] This component achieves rapid and accurate bracket positioning through precise matching between the bracket body 100 and the tooth surface 20, and the pre-set mounting slot 210 position on the positioning block 200. Doctors no longer need to repeatedly adjust the bracket position inside the mouth, nor rely on additional measuring tools to determine the bracket's tilt angle, greatly simplifying the procedure, shortening clinical operation time, and significantly improving treatment efficiency. The clear graduations on the tilt indicator 300 provide doctors with an intuitive and precise angle reference, ensuring the accuracy of the bracket bonding angle, reducing rework due to angle deviations, and further guaranteeing treatment efficiency and quality.

[0079] Finally, the positioning block 200 has a mounting groove 210, and the first end 301 of the scale marking portion 310 of the tilt indicator 300 is suspended and detachably assembled into the mounting groove 210. The rod-shaped scale marking portion 310 forms a clearly defined, operable space on both sides. During bracket bonding, when adhesive overflows between the bracket base and the tooth 20, this space provides a clear operating path and point of application for the dentist to use scaling tools (such as probes or specialized scrapers). The dentist can more easily and precisely scrape away excess adhesive without worrying about interference between the tool and the complex one-piece structure.
