Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is an international patent application of U.S. Patent Application No. 18 / 218,378, filed on July 5, 2023, and claims priority to U.S. Provisional Application No. 63 / 393,454, filed on July 29, 2022. Each application is incorporated by reference in its entirety for all purposes. Technical Field

[0003] The present disclosure relates to a dental device, and more particularly to a dental device that assists in applying one or more dental brackets to teeth. Prior art

[0004] Orthodontics is a device used to align teeth to a desired arrangement. Generally speaking, a dental brace includes brackets that are individually fixed to each tooth, and an archwire that connects each bracket, and the teeth are moved by the combined force of the bracket and the archwire. In the prior art, commonly used bonding methods include direct bonding and indirect bonding. Indirect bonding uses a model or prefabricated mold to apply the entire set of braces (including all brackets and additional components, such as expanders, temporary bone fixation devices (TADs), palatal arches (TPAs), anterior and posterior braces, etc.) to the teeth at one time. However, indirect bonding requires the production of molds and related components, resulting in higher costs and longer production time. In direct bonding, each bracket needs to be individually fixed to each tooth, which is more time-consuming and difficult to ensure that the bracket arrangement meets the settings of the overall brace. For example, if the position of the first bracket is slightly deviated, the dentist performing the orthodontic treatment may not be able to detect it immediately, and the problem will not be discovered until all brackets are installed. To correct the error, the dentist performing the orthodontic treatment may need to adjust the installed brackets one by one, which is a difficult and time-consuming process.

[0005] Therefore, there is an urgent need for a technology or device that can quickly apply and fix brackets on teeth, so that dentists performing orthodontic treatment can adjust the positions of all brackets in real time during the treatment process. In addition, there is also an urgent need for a technology that can simultaneously apply all brackets and corresponding archwires to improve the installation efficiency of braces and reduce treatment time. Summary of the invention

[0006] The present disclosure provides an embodiment of a dental device. The dental device includes a tooth bracket, which can be used to fix a corresponding tooth. The dental device further includes a support member, which can be connected to the tooth bracket through an extension portion, and the extension portion supports the corresponding tooth bracket at a predetermined position.

[0007] In the dental device, the extension can support the corresponding tooth bracket in a predetermined position so that it can be aligned with the corresponding tooth. The dental device may further include an archwire, which is pre-threaded through the connector of the tooth bracket. The dental device may include an archwire, which can be used to pass through the connector of the bracket. The tooth bracket may include a shell having a curved surface, which can be aligned with the teeth and includes a cutout to increase the surface area of ​​the curved surface. The tooth bracket may include a connector integrated with the shell, which can be connected to the archwire. The dental device can be manufactured by a single continuous mold, so that the support, the tooth bracket and the extension are an integrally formed structure. The tooth bracket may include a connector connected to the archwire. The tooth bracket may also include a hole extending from one surface of the tooth bracket to another surface, so that the archwire can pass through the hole and connect with the tooth. The support may include a block, which can be used to guide the dental device on the teeth. The support can be placed on the upper jaw of the user so that the tooth bracket extends toward the teeth. The dental device may further include a guide member connected to the extension and disposed between the tooth bracket and the support member to guide the bracket to be cut from the corresponding extension. The guide member may include a pair of attachments, the pair of attachments defining a channel for guiding the tooth bracket to be cut from the corresponding extension. The dental device may further include a cutter, the cutter may be engaged with the guide member and used to cut the tooth bracket from the extension.

[0008] The present disclosure provides an embodiment of a dental bracket. The dental bracket includes a shell having a curved surface, the curved surface is used to align teeth, and includes a cutout to increase the surface area of ​​the curved surface. The cutout can increase the surface area of ​​the dental bracket in contact with the adhesive to promote the combination of the dental bracket and the teeth. The dental bracket further includes a connector, which is integrated with the shell and is used to connect to the archwire.

[0009] The connector includes a hole that passes through one surface of the housing to the other surface for the arch wire to pass through the dental bracket. The connector may further include a support post that is used to fix the arch wire when the band is applied to the support post. The cutout can increase the surface area of ​​the dental bracket in contact with the adhesive to improve the bonding force between the dental bracket and the tooth. The dental bracket can be separated from the support of the dental device to facilitate its application to the tooth. The connector may include a channel that passes through the housing.

[0010] The present disclosure further provides a method of applying a dental bracket and / or a dental device. The method includes: positioning the dental device in the mouth of a user so that the dental bracket extends from a support to the user's teeth; activating an adhesive to secure the dental bracket to the user's teeth; and separating the dental bracket from the support so that the dental device can be removed from the mouth while the dental bracket remains secured to the teeth.

[0011] The method may further include: passing an archwire through the dental bracket to apply a corrective force to the tooth. The method may further include: adjusting the position of the dental bracket on the tooth while the dental bracket is still connected to the support. The method may include cutting or drilling the extension to separate the dental bracket from the support. The support and the dental bracket may be formed of a continuous material. Separating the dental bracket from the support may include: applying a cutter to the channel for the extension to separate the dental bracket from the extension. The application of the dental device can be applied without a mold or model, and all dental brackets can be applied at one time.

[0012] The present disclosure provides a device and method for applying dental brackets to teeth in a synchronized manner by using a support and an extension. A dentist can pre-align the dental brackets in a desired occlusal position through a digital design and transfer the design to the user's teeth to accelerate the braces alignment process.

[0013] Another way to speed up the process is to pre-thread the archwire through the dental device, so that the dentist can place the dental bracket and the archwire on the teeth at one time without the need to additionally fix the archwire after the combination. When the dentist performing the orthodontic treatment pre-coats the adhesive on the base pad of the dental bracket and places the dental bracket on the teeth in the desired arrangement, the adhesive is activated to lock the dental bracket in place and cut from the extension. With this design, the dentist performing the orthodontic treatment can simultaneously apply and align multiple dental brackets before the adhesive is activated, thereby shortening the braces application time and reducing the risk of errors that affect the arrangement of other dental brackets.

[0014] In addition, by having all the tooth brackets extend from the support, the dentist performing the orthodontic treatment can directly align the tooth brackets without having to take them out one by one from a tray or other storage device. When the installation is completed, the guide member can be used to guide a cutting tool (such as a drill or a cutter) to cut the tooth bracket to improve cutting accuracy and reduce residual material on the tooth bracket.

[0015] The tooth bracket can be designed to include one or more cutouts. The cutouts can correspond to the protrusions, so that a suspended mesh structure is formed inside the tooth bracket. This design can improve the bonding strength between the tooth bracket and the corresponding tooth, because the adhesive can fill the cutouts and surround the protrusions to enhance the holding force between the adhesive and the corresponding tooth.

[0016] Advantageously, the integral dental device can be manufactured from a continuous material and can be fabricated by a variety of techniques (eg, 3D printing), thereby reducing production costs.

[0017] The dental braces disclosed herein include dental brackets and archwires, and the dental braces can apply corrective forces to teeth to realign the teeth to a desired position. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present disclosure relates to a dental device, which includes a support member, which is used to guide the placement of brackets so that the dentist can install all brackets to the predetermined position on the teeth at the same time. Because the brackets are connected to the support member through an extension that can be cut from the bracket, the dentist can adjust the bracket arrangement according to the needs of individual patients before fixing the brackets. When all brackets are positioned in the appropriate position, they can be fixed at one time without installing each bracket one by one, thereby avoiding the problem of having to readjust individual brackets when the archwire is not properly aligned. In addition, each bracket may include one or more incisions and / or protrusions, so that the dentist performing orthodontic treatment can apply an appropriate amount of adhesive and retain the adhesive inside the bracket through the incision to enhance the adhesion between the bracket and the tooth. Further configuring a guide member can assist the dentist performing orthodontic treatment to quickly apply the bracket and separate the bracket from the extension to reduce or eliminate the material remaining on the bracket after cutting or drilling.

[0033] Figure 1 A three-dimensional diagram showing an example of a dental device 100 fixed on a tooth 102. The dental device 100 is installed on the lingual side 104 of the tooth 102, so when part of the dental device 100 is removed from the oral cavity, the brace (not shown) can be hidden by the buccal side 106 of the tooth 102 and is not easily noticed by others. The dental device 100 includes a support 108 and a bracket 110, and the bracket 110 is connected to the support 108 by an extension 112. The extension 112 can be a plastic material, so that the bracket 110 can be adjusted to a desired arrangement or position along the lingual side 104 of the tooth 102, and then an archwire (e.g. Figure 5 The bracket 110 is used to receive and / or connect with the arch wire (such as Figure 5 The archwire 518 is connected to the tooth 102 to apply a corrective force to the tooth 102, thereby moving the tooth to a desired alignment position.

[0034] The support 108 includes a beam 114 and a block 116, which are used to guide the dental device 100 to be fixed on the tooth 102. The beam 114 can have any suitable configuration to support the block 116 and the bracket 110, so that the dentist can efficiently fix the braces in the user's mouth. In some embodiments, the support 108 does not include the block 116, and the beam 114 can directly contact the tooth 102. In this case, the beam 114 can have a shape corresponding to the shape of the tooth 102 to ensure alignment and fixation. In addition, in other embodiments, the beam 114 can be a plastic material, so that the dentist can press the beam 114 on the tooth 102 and adjust its curvature to align the top surface of the tooth 102. For example, an auxiliary component (not shown) can be included to assist in applying the adhesive to the bracket 110 and / or the tooth 102, so that the dentist can quickly apply the adhesive.

[0035] The block 116 is shown as a square, but it can have other shapes to provide a sufficient support base, thereby reducing or alleviating the shaking that may occur when the dental device 100 is fixed to the bracket 110. For example, the block 116 can be rectangular, cylindrical, circular, or any combination thereof. The surface of the block 116 that contacts the tooth 102 can be used to align the side or top surface of the tooth 102. In other embodiments, the block 116 has plasticity, and when the dental device 100 is placed on the tooth 102, it can better fit the tooth shape of different users. In addition, the block 116 can have a suitable shape so that it can be properly embedded in the groove between the teeth 102. The support 108 can include a sufficient number of blocks 116 to ensure the alignment accuracy of the bracket 110 on the tooth 102. For example, the support 108 can include more than one, more than two, more than three, more than four, more than five, or more blocks 116.

[0036] The support 108 may include an appropriate amount or a specific type of brackets 110 to accommodate different orthodontic appliances or braces. For example, the support 108 may include a number of brackets 110 corresponding to the number of teeth 102 to meet the needs of a specific user. In addition, the support 108 may also include a smaller number of brackets 110, rather than the same number as the teeth 102. For example, some orthodontic components (such as expanders) may not be applied to all teeth 102 in the oral cavity. In other embodiments, brackets 110 may not be used and may be replaced by other orthodontic components. The support 108 may include any one or more orthodontic components and is connected to the support 108 by an extension 112. As shown in the figure, the extension 112 extends from the lingual side 104 of the beam 114 so that the bracket 110 can be fixed to the lingual side 104 of the tooth 102. In other configurations, additional extensions 112 may be added to the buccal side 106 of the beam 114 and include additional brackets 110 or alternative orthodontic components. Likewise, when the bracket 110 is secured to the buccal side 106 of the tooth 102 , the extension 112 including a replacement orthodontic component or bracket 110 may be disposed on the lingual side 104 of the beam 114 .

[0037] The function of the extension 112 is to provide a plastic and detachable connection between the bracket 110 and the support 108. The extension 112 can be both plastic so that the dentist can adjust the position of the bracket 110, and can maintain a certain rigidity so that the bracket 110 remains in the desired position after adjustment unless the dentist adjusts it again. The extension 112 can be separated from the bracket 110 by cutting or drilling so that the support 108 can be separated from the bracket 110 and removed from the oral cavity. The cutting or drilling can be performed by any tool sufficient to separate the two components. In addition, in other embodiments, the extension 112 can be separated from the bracket 110 and / or the support 108 by solvent treatment, heating, or ultraviolet light irradiation. The extension 112 may include one or more weak areas adjacent to the support 108 and / or the bracket 110, making it easier to cut or separate than other areas.

[0038] Figure 2 Another embodiment of a dental device 200 is shown, and the dental device 200 is fixed to a tooth 202. The dental device 200 is disposed on the lingual side 204 of the tooth 202, so that when the dental brace is fixed, the dental brace cannot be directly seen from the buccal side 206 of the tooth 202. The dental device 200 includes a support 208 connected to a bracket 210 via an extension 212. The structures of the support 208, the bracket 210, and the extension 212 can be similar to Figure 1 The support 108, bracket 110, and extension 112 shown are similar.

[0039] The support member 208 includes an extension 214, which is further connected to a block 216 to prevent the dental device 200 from sliding or misaligning when worn. In addition, the block 216 can be configured according to the oral structure of the user to assist the bracket 210 in precise alignment. Figure 1 Blocks 116 and 216 shown may have a shape suitable for guiding the dental device 200 on the tooth 202. The support member 208 may be a plastic material, so that the dentist can adjust its shape to better fit the user's oral structure and improve the alignment accuracy of the dental device 200.

[0040] The support member 208 can be designed in any suitable shape to avoid interfering with the dentist's operation of installing the bracket 210 on the tooth 202. In addition, the support member 208 can be placed on the upper jaw surface or gum tissue in the oral cavity to provide auxiliary support. The support member 208 can also be designed to be suitable for placement at the bottom of the oral cavity (i.e., under the tongue) to reduce interference with the dentist's installation of the bracket 210.

[0041] Figure 3Another embodiment of a dental device 300 is shown, and the dental device 300 is fixed to a tooth 302. The dental device 300 is disposed on the buccal side 306 of the tooth 302, and is more convenient to install than the lingual side 304. The dental device 300 includes a support 308 connected to a bracket 310 via an extension 312. The support 308 further includes a beam 314, and the beam 314 is disposed on a block 316, so that the beam 314 is spaced apart from the tooth 302 to avoid direct contact. The structure of the support 308, the bracket 310, the extension 312, the beam 314, and the block 316 can be similar to Figures 1 to 2 The supports 108 and 208, brackets 110 and 210, extensions 112 and 212, beams 114, and blocks 116 and 216 are shown to be similar.

[0042] The bracket 310 includes struts (tiewings) 318 to allow the archwire (e.g., Figure 5 The arch wire 518 can be placed in a slot in the support 318 and fixed by the upper and lower support 318. In addition, a ring band (not shown) can be used to fix the arch wire (e.g., Figure 5 The archwire 518) is further fixed to the bracket 310. The bracket 310 can include any number of struts 318 to secure the archwire (e.g., Figure 5 The archwire 518 of the bracket 310 is fixed to the bracket 310. For example, the bracket 310 may include 2 to 8 pillars 318.

[0043] The bracket 310 includes a connector 320, which is configured to be connected to a ring band (not shown) to assist in adjusting the position of the mandible. According to the needs of the user or the dentist, the bracket 310 may include one or more connectors 320, and a single bracket 310 may include multiple connectors 320. In some embodiments, the connector 320 may be replaced by other correction components, which can be used to adjust the alignment of the user's teeth 302.

[0044] Figure 4A A rear view of a bracket 400 is shown, and the bracket 400 may be suitable for Figures 1 to 3 The dental devices 100, 200, 300 are shown. The bracket 400 includes an outer periphery 402 (or outer surface), the outer periphery 402 is connected to a side surface 403, and the side surface 403 has a hole 404, the hole 404 forms a channel 416, and the channel 416 is configured to receive an arch wire (e.g., Figure 5 The holes 404a and 404b may have any size or configuration to accommodate an archwire (e.g., Figure 5The bracket 400 may further include another set of holes (not shown), and the holes may form another channel (not shown) so that a second archwire can be used to assist in adjusting the position of the teeth (not shown). In addition, the bracket 400 may include additional holes (not shown) and / or channels (not shown) arranged in other directions to connect other correction components for tooth realignment or adjustment.

[0045] To enhance the bonding effect between the bracket 400 and the teeth, a cutout 406 is provided on the back side 408 of the bracket 400. The cutout 406 can enhance the holding force (bonding force) of the bracket 400, so that the dentist can apply adhesive before inserting the dental device (e.g., dental device 100, 200, 300) into the oral cavity, thereby reducing or preventing the adhesive from dripping when the bracket 400 is applied to the teeth. The back side 408 is for the bracket 400 to be used when the dental device (e.g., Figures 1 to 3 The portion of the dental device 100, 200, 300 shown in the figure that contacts the tooth (not shown) when the brace is fixed. The bracket 400 may include any number of cutouts 406 to ensure that when the bracket 400 is fixed to the tooth (not shown), the bonding effect can be improved and the surface area can be increased to prevent the adhesive from dripping from the bracket 400 before activation. For example, the bracket 400 may include 1 to 30 cutouts 406.

[0046] On the back side 408, a shelf-like protrusion 410 is provided adjacent to the periphery 402, and the cutouts 406 are separated by raised surfaces 412. The cutouts 406 can form a continuous area for adhesive deposition, and the raised surfaces 412 are located above the continuous area so that it functions as a mesh structure (e.g., a suspended mesh configuration). The combined effect of the shelf-like protrusion 410 and the cutouts 406 can enhance the retention of the adhesive on the tooth bracket 400, regardless of the dental device (e.g., Figures 1 to 3The dental device 100, 200, 300 shown in the figure is applied with adhesive before or after insertion into the oral cavity. Since the incision 406 forms a recessed surface compared to the periphery 402 and / or the frame-like protrusion 410, the adhesive pre-applied to the tooth bracket 400 will not drip from the tooth bracket 400 before activation, thereby accelerating the process of fixing the braces to the user's oral cavity. The surface of the frame-like protrusion 410 and the protrusion surface 412 can be relatively uniform and flat. In some embodiments, the frame-like protrusion 410 and the protrusion surface 412 form a continuous flat surface. In other embodiments, the surface of the frame-like protrusion 410 and the protrusion surface 412 can be stepped. For example, when the frame-like protrusion 410 is higher than the protrusion surface 412, and the protrusion surface 412 is higher than the cutout 406, the cutout 406 and the protrusion surface 412 may be additionally filled with adhesive, and the adhesive may be limited between the tooth bracket 400 and the tooth (not shown) by the frame-like protrusion 410 to improve the adhesion between the tooth bracket 400 and the tooth (not shown) and prevent the adhesive from leaking out of the frame-like protrusion 410. In some embodiments, the tooth bracket 400 may not include a complete protrusion surface 412, but may have more open cutouts 406, thereby maximizing the volume of the tooth bracket 400 that can be filled with adhesive, thereby improving the adhesion ability.

[0047] Figure 4B for Figure 4A A cross-sectional view of a dental bracket 400 is shown, which can be applied to Figures 1 to 3 The dental apparatus 100, 200, 300 shown. The dental bracket 400 includes a front face 414 and a back face 408, between which a channel 416 is sandwiched. The channel 416 extends through the holes 404a, 404b to allow the arch wire (e.g., Figure 5 An archwire 518 (e.g., a brace 518) may be passed through the tube 416 to secure the brace to the teeth (not shown). The tube 416 is disposed behind the cutout 406 to maximize the internal volume of the cutout 406. In other embodiments, the tube 416 may extend through the cutout 406, which may be used when the thickness of the front face 414 is not sufficient to completely accommodate the tube 416. The cross-sectional shape of the tube 416 may be any suitable shape for an archwire (e.g., Figure 5 The cross-sectional area of ​​the holes 404a, 404b may be larger than the cross-sectional area of ​​the tube 416, making it easier for the dentist to insert the arch wire (e.g., Figure 5 The archwire 518 is passed through the holes 404a, 404b and the tube 416 because the openings of the holes 404a, 404b are larger. For example, the tube 416 can have a circular, rectangular, triangular or any shape suitable for threading the archwire (e.g., Figure 5In some embodiments, the channel 416 may be designed to be tapered so that it is narrowest in the central portion of the dental bracket 400 and widest near or at the holes 404a, 404b to facilitate insertion of the archwire. The dental bracket 400 may include one or more channels 416 to allow one or more archwires (e.g., Figure 5 The front face 414 and the back face 408 may have curved surfaces so that the dental bracket 400 can fit a specific tooth (not shown). The front face 414 and the back face 408 may have any structure suitable for fitting the shape of a tooth (not shown). In other embodiments, the front face 414 and the back face 408 may not have curved surfaces, but may be generally straight structures to meet different correction requirements.

[0048] The combination of the tube 416 and the holes 404a, 404b can be described as a connector for connecting to an archwire (e.g., Figure 5 The connector can be used to connect a tooth bracket (e.g., Figures 1 to 4B The tooth bracket 110, 210, 310, 400) and the arch wire (for example, Figure 5 The connector may be connected to an archwire 518) to adjust and / or realign the user's teeth. The connector may be used in conjunction with one or more other orthodontic components described herein that are used to adjust and / or realign teeth. The connector may extend through a tooth bracket (e.g., Figures 1 to 4B The tooth bracket 110, 210, 310, 400) may be provided on the outer surface of the tooth bracket (for example, Figures 1 to 4B The tooth bracket 110, 210, 310, 400) is disposed, for example, on the front face 414. For example, as described herein, the connector can be connected to the support (e.g., Figure 3 The support 318 is used in conjunction with the support to provide a channel for the arch wire (e.g., Figure 5 The archwire 518 can be passed through and can be fixed to the tooth bracket (e.g., Figures 1 to 4B Tooth brackets 110, 210, 310, 400).

[0049] Figure 5 FIG. 5 is a perspective view of another example of a dental device 500, which is fixed to a tooth 502. The dental device 500 is connected to the lingual side 504 of the tooth 502 so that when the dental brace is assembled, the dental brace cannot be seen from the buccal side 506 of the oral cavity. The dental device 500 includes a support 508, which is connected to the tooth bracket 510 through an extension 512. The support 508 includes a beam 514 and a block 516, and the block 516 is used to assist the alignment of the dental device 500 with the tooth 502. The structure of the support 508, the tooth bracket 510, the extension 512, the beam 514 and the block 516 can be similar to Figures 1 to 4B The dental device 500 further includes an archwire 518 that is pre-threaded through a connector 520 of the dental bracket 510 to speed up the process of applying the dental appliance to the tooth 502. The connector 520 may be similar to Figures 4A to 4B The pipe 416 and holes 404a, 404b, or similar Figure 3 The adhesive may be applied to the dental bracket 510 before or after the dental device 500 is mounted to the tooth 502.

[0050] The archwire 518 can be used to apply a corrective force to the dental bracket 510 and / or the teeth 502 to adjust the position and / or alignment of the user's teeth 502. The archwire 518 can have any suitable structure for adjusting the position and / or alignment of the user's teeth 502, and can be made of any material sufficient to adjust the position and / or alignment of the user's teeth 502, such as metal, plastic, or a combination thereof. Figure 5 In the illustrated example, the archwire 518 is preloaded, pre-threaded, or pre-installed in the tooth bracket 510 before the dental device 500 is installed in the user's mouth. In other examples, the archwire 518 is added after the tooth bracket 510 is fixed to the tooth 502 by adhesive. The archwire 518 can be pre-shaped or pre-aligned to connect multiple tooth brackets 510 and apply corrective forces thereto, so that the tooth bracket 510 is pre-aligned to the arrangement of the teeth 502 of a specific user.

[0051] Although not shown, Figures 1 to 3 The dental devices 100, 200, 300, 500 of the present invention may include any other orthodontic components included in conventional orthodontic devices. For example, the dental devices 100, 200, 300, 500 may include orthodontic components such as loops, hooks, buccal tubes, buttons, palatal arches, lower lingual retaining arches, rapid expanders, lingual cemented retainers, Nance appliances, W-shaped arches, palatal temporary bone dowels (TADs), MARA appliances, Carriere appliances, Herbst appliances, or any other components sufficient to adjust or realign the user's teeth. In some embodiments, a tooth bracket (e.g., Figures 1 to 5 The dental brackets 110, 210, 310, 400, 510) can be used in conjunction with or replaced by one or more orthodontic components. The dental devices 100, 200, 300, 500 can be placed in the mouth or on the teeth as described herein, while other orthodontic components are installed or fixed in the mouth or on the teeth.

[0052] In some embodiments, it may be desirable to apply two dental devices (not shown) and install them sequentially. For example, a first dental device (not shown) may be applied to the lower teeth first, and after the lower tooth brackets of the first dental device are secured to the teeth and separated from the extension, a second dental device (not shown) may be applied to the upper teeth, and then the second dental device may be removed from the upper teeth. The upper and lower dental devices (not shown) may have the same configuration (e.g., a dental device that includes all tooth brackets), or the upper and lower dental devices (not shown) may include different types of tooth brackets, orthodontic components, or both.

[0053] In some embodiments, the dental devices 100, 200, 300, 500 may be pre-customized according to the oral cavity of a specific user so that the tooth bracket (e.g. Figures 1 to 5 The dental brackets 110, 210, 310, 400, 510) can be pre-positioned and may or may not include an archwire (e.g. Figure 5 For example, before manufacturing the dental device 100, 200, 300, 500, a three-dimensional (3D) model or dental mold of the user's teeth can be created. The 3D model or dental mold can be used to determine the customized positioning of each component in the dental device 100, 200, 300, 500 to achieve the best tooth arrangement and / or adjustment effect.

[0054] The dental devices 100, 200, 300, 500 described herein may be made of any material suitable for forming an orthodontic component. For example, the dental devices 100, 200, 300, 500 may be made of a metal material, a ceramic material, and / or a polymer material. In certain embodiments, the dental devices 100, 200, 300, 500 may be made of a mixture of multiple materials, such as reinforced plastics, copolymers, metal alloys, or hybrid ceramic materials. Examples of metal materials include 316 stainless steel, cobalt-chromium alloy (CoCr), and titanium. Examples of polymer materials include polyurethane, polyethylene, poly(lactic-co-glycolic acid), polymethylmethacrylate, and / or polyether ether ketone. Examples of ceramic materials include alumina (Al2O3), zirconium oxide (ZrO2), porcelain, and / or hydroxyapatite. In certain embodiments, a support member (e.g. Figures 1 to 3 The support members 108, 208, 308) can be made of a first material, and the tooth bracket (e.g. Figures 1 to 5The tooth bracket 110, 210, 310, 400, 510) can be made of a second material, which is suitable for use as an orthodontic component, and the extension (e.g. Figures 1 to 3 The extension portions 112, 212, 312, 512) of and 5 may be made of a third material or a mixed material of the first material and the second material.

[0055] The dental devices 100, 200, 300, 500 described herein may be manufactured by any technique suitable for manufacturing an orthodontic appliance. The dental devices 100, 200, 300, 500 may be made of a single continuous material and may be manufactured by any suitable process. For example, the dental devices 100, 200, 300, 500 may be manufactured by a 3D printing process such that they are a single continuous material. In certain embodiments, the dental devices 100, 200, 300, 500 may be manufactured by direct printing or indirect printing. Examples of suitable 3D printing processes include loss of wax, vat photopolymerization, material jetting, binder jetting, powder bed fusion, material extrusion, directed energy deposition, sheet lamination, direct metal laser sintering, or any combination thereof. In other embodiments, the dental device may be manufactured by injection molding, assembly, or any combination thereof.

[0056] The dental device 100, 200, 300, 500 may be composed of a plurality of components, which may be connected to each other by bonding or other means. For example, a support member (e.g., Figures 1 to 3 and Figure 5 The support members 108, 208, 308, 508 shown may be bonded or connected to the extension (e.g. Figures 1 to 3 and Figure 5 The extensions 112, 212, 312, 512 shown), and the brackets (e.g.: Figures 1 to 5 The brackets 110, 210, 310, 400, 510) shown may be bonded or connected to an extension (e.g.: Figures 1 to 3 and Figure 5For example, the bracket (e.g., bracket 110, 210, 310, 400, 510) may be made of metal, while the support (e.g., support 108, 208, 308, 508) may be made of plastic material to reduce costs while ensuring that the bracket (e.g., bracket 110, 210, 310, 400, 510) is made of a suitable metal material because the bracket (e.g., bracket 110, 210, 310, 400, 510) needs to be continuously fixed to the teeth during tooth realignment and / or adjustment. When different components (e.g., bracket 110, 210, 310, 400, 510 and support 108, 208, 308, 508) are made of different materials, the two components can be bonded or fused together by any method sufficient to form a separable (e.g., cuttable) connection.

[0057] The dental devices 100, 200, 300, 500 described herein may be mounted via any suitable mounting bracket (e.g., Figures 1 to 5 The brackets 110, 210, 310, 400, 510 shown are placed on the teeth and the support (e.g. Figures 1 to 3 and Figure 5 The supports 108, 208, 308, 508) and / or extensions (e.g.: Figures 1 to 3 and Figure 5 For example, the support member (e.g., support member 108, 208, 308, 508) of the dental device 100, 200, 300, 500 may be placed on the tooth, so that the bracket (e.g., bracket 110, 210, 310, 400, 510) faces or covers the tooth, and an adhesive is applied to the bracket (e.g., bracket 110, 210, 310, 400, 510). After the bracket (e.g., bracket 110, 210, 310, 400, 510) is coated with the adhesive, it may be positioned on the tooth, and the adhesive may be activated by any suitable method to fix the bracket (e.g., bracket 110, 210, 310, 400, 510) to the tooth. The position of the bracket (e.g., bracket 110, 210, 310, 400, 510) on the tooth can be adjusted before the adhesive is activated. The bracket (e.g., bracket 110, 210, 310, 400, 510) can be cut and removed from the support (e.g., support 108, 208, 308, 508) before or after the adhesive is activated. The adhesive can be activated by heat, ultraviolet radiation, air, water, and / or pressure.

[0058] Archwires (e.g. Figure 5 The archwire 518 shown may be attached to the bracket (e.g., before or after the adhesive is activated) Figures 1 to 5The brackets 110, 210, 310, 400, 510 shown are connected. Archwires (e.g.: Figure 5 The archwire 518 shown and / or the bracket (e.g., bracket 110, 210, 310, 400, 510) may be self-supporting (e.g., before the adhesive is activated and / or the bracket (e.g., bracket 110, 210, 310, 400, 510) is self-supporting (e.g., Figures 1 to 3 and Figure 5 The support members 108, 208, 308, 508 shown are adjusted before cutting, so that the dentist can quickly and simultaneously check the position of the brackets (e.g., brackets 110, 210, 310, 400, 510) and make fine adjustments before the braces are officially fixed in the user's mouth. The support members (e.g., support members 108, 208, 308, 508) can be placed or supported on the teeth and / or the upper jaw so that the brackets (e.g., brackets 110, 210, 310, 400, 510) extend toward the teeth. The dental device 100, 200, 300, 500 can be installed on the upper or lower teeth first, and the brackets (e.g., brackets 110, 210, 310, 400, 510) can be fixed on the upper or lower teeth in any order.

[0059] When the dental device 100, 200, 300, 500 further comprises other correction components, the correction components can be installed on the teeth in any order. Figures 1 to 5 The blocks 116, 216, 316, 516 shown can be used to interlock with the occlusal surface of the tooth to stabilize the support member (e.g., support member 108, 208, 308, 508) from moving or shifting when the dentist fixes the bracket (e.g., bracket 110, 210, 310, 400, 510) to the tooth. After the bracket (e.g., bracket 110, 210, 310, 400, 510) is fixed to the tooth, the extension (e.g., Figures 1 to 3 and Figure 5 The extensions 112, 212, 312, 512 shown are removed and the temporary adhesive on the support member (e.g., support members 108, 208, 308, 508) is ineffective by destruction, heating and / or ultraviolet irradiation so that the support member can be removed from the oral cavity.

[0060] Figure 6 A perspective view showing an orthodontic appliance 600 mounted on a tooth 602, the orthodontic appliance 600 being an extension (e.g. Figures 1 to 3 and Figure 5 The extensions 112, 212, 312, 512) and the support members (e.g.: Figures 1 to 3 and Figure 5After the support members 108, 208, 308, 508 shown are cut, only the brackets 610 and the archwire 608 are left to form the aligner 600. The aligner 600 is placed on the lingual side 604 of the tooth 602 so that the aligner 600 is not visible from the buccal side 606 of the tooth 602. The aligner 600 is fixed to the tooth 602 by an adhesive so that the brackets 610 are firmly attached to the tooth 602. The aligner 600 can be applied or positioned to the tooth by any of the techniques or methods described herein. The brackets 610 and the archwire 608 can be attached to the tooth 602. Figures 1 to 5 The brackets 110, 210, 310, 400, 510 and the archwire 518 are shown to be the same. In other embodiments, the aligner 600 can be placed on the buccal side 606 of the tooth 602. Figures 1 to 3 and Figure 5 Any of the dental devices 100 , 200 , 300 , 500 shown can enable the aligner 600 to be fixed to the lingual side 604 or the buccal side 606 of the tooth 602 .

[0061] Figure 7 A perspective view showing the interaction of the dental device 700 with teeth. The dental device 700 can be used with Figures 1 to 5 The dental devices 100, 200, 300, 400, 500 are similar. Dental device 700 includes a support 708 connected to a bracket 710 via an extension 712. Support 708 includes a beam 714 connected to the extension 712 and supported by a block 716 disposed on the tooth 702. Bracket 710 includes a connector 720 for connecting to an archwire (not shown, see e.g., Figure 5 and Figure 6 The archwires 518, 618 shown in FIG. 5A and 5B interact with each other, and the connector 720 may be similar to Figure 3-5 The connector 520, the pipe 416 and / or the support 318 are shown. The structure of the support 708, the bracket 710, the extension 712, the beam 714 and the block 716 can be similar to Figures 1 to 6 The support members 108 , 208 , 308 , 508 , brackets 110 , 210 , 310 , 400 , 510 , 610 , extensions 112 , 212 , 312 , 512 , beams 114 , 314 , 516 and / or blocks 116 , 216 , 316 , 516 are shown.

[0062] The dental device 700 includes a guide 722 for use with a cutter (e.g., Figure 8The bracket 710 can be removed from the extension 712 by interaction with a cutter 824 (shown in the figure) or other cutting device or drill. In some embodiments, the guide 722 can be disposed on the extension 712 or disposed between the extension 712 and the bracket 710 so that when the bracket 710 is separated from the extension 712, little or no residual portion of the extension 712 remains on the bracket 710. If the bracket 710 is accurately cut, the person applying the dental device 700 can easily remove it from the bracket 710 without further grinding, polishing or removing the portion of the extension 712 remaining on the bracket 710. When the guide 722 is not used for cutting, there may be a residual portion of the extension that affects the surface quality of the bracket 710. In some embodiments, the guide 722 can be used to assist the person applying the dental device 700 in adjusting the position of the bracket 710 before the user activates the adhesive or finalizes the arrangement of the bracket 710. For example, a tool (not shown) or a cutter (e.g. Figure 8 The cutter 824 shown interacts or is connected to the guide 722 without cutting the guide 722 from the extension 712 and / or the bracket 710 to facilitate adjusting the bracket 710 to a desired position before cutting, before installing an archwire, and / or before activating any adhesive.

[0063] The guide member 722 may be made of any material having sufficient strength to interact with the tool or cutter to allow the user to adjust the bracket 710. For example, the guide member 722 may be made of the same material as the support member 708 and / or the bracket 710 and may form a continuous portion of the dental device 700. In addition, the guide member 722 may be bonded or connected to the bracket 710 and / or the extension 712 after the dental device 700 is formed, allowing the user to adjust the position of the guide member 722 to optimize the cutting effect and / or facilitate the separation of the bracket 710 and the extension 712.

[0064] The guide 722 can be configured in an appropriate position or used to assist the user in cutting and / or separating the bracket 710 from any direction relative to the gums. For example, the user may wish to cut and / or separate the bracket 710 from the side of the gums (e.g., Figure 8 ), the side of the tooth 702, or one side of the bracket 710 (i.e., in the direction toward another bracket 710), the guide member 722 can be configured accordingly to assist the user in achieving the desired cutting direction. In some embodiments, the guide member 722 can include an opening (not shown) or other structural features to enable it to rotate around the extension 712, thereby assisting the user in adjusting the bracket 710 and / or separating it from the extension 712 in any direction.

[0065] Figure 8 is a perspective view of a dental device 800, which may be similar to Figures 1 to 35 to 7, and is engaged with a tooth 802. The dental device 800 includes a support 808, and the support 808 is connected to the bracket 810 through an extension 812. The support 808 further includes a beam 814, and the beam 814 is connected to the extension 812 and supported by a block 816 disposed on the tooth 802. The bracket 810 includes a connector 820, and the connector 820 is used to connect with an arch wire (not shown, see Figures 5 to 6 The archwires 518, 618) are joined, and the connector 820 may be similar to Figures 3 to 5 The connector 520, the pipe 416 and / or the support 318 are shown. The structure of the support member 808, the bracket 810, the extension 812, the beam 814 and the block 816 can be similar to Figures 1 to 5 7, the support members 108, 208, 308, 508, 708, the brackets 110, 210, 310, 400, 510, 610, 710, the extensions 112, 212, 312, 512, 712, the beams 114, 314, 514, 714 and / or the blocks 116, 216, 316, 516, 716. In addition, the dental device 800 further includes a guide member 822, which can be similar to Figure 7 Guide 722 is shown.

[0066] like Figure 8 As shown, the cutter 824 is shown physically separate from the dental device 800 (but can be included as part of the component kit or 3D mold of the dental device 800). The cutter 824 is used to separate the bracket 810 from the extension 812, and can be used manually by a user, an automatic machine, a controllable machine, a robot, or any combination thereof. The cutter 824 can have any suitable structure for cutting the bracket 810 from the dental device 800, and can be designed to cooperate with the guide 822 to enable the user to quickly and efficiently separate the bracket 810 from the dental device 800. The cutter 824 can have an appropriate size to ensure that the cutter 824 can be placed in the user's mouth when the bracket 810 is applied to the inside or outside of the tooth 802. In some embodiments, the cutter 824 or a portion thereof can be integrated with the dental device 800 so that it forms a continuous part of the dental device 800. In other embodiments, the cutter 824 may be assembled from multiple components, wherein one or more of the handle 826, the column 828, and the blade 830 are bonded together or integrally formed.

[0067] The guide 822 includes a pair of appendages 832a, 832b that define a channel 834 for contacting and interacting with the post 828 and the blade 830 to encourage a user to cut the bracket 810 from the extension 812. In certain embodiments, one or more pairs of appendages 832a, 832b (e.g., two to eight appendages) may be used to interact with one or more posts 828 connected to the blade 830. The appendages 832a, 832b may be angled to accommodate the post 828, the blade 830, and / or any other tool for adjusting the bracket 810 and / or cutting the bracket 810 from the corresponding extension 812.

[0068] The appendages 832a, 832b may have any shape sufficient to accommodate the blade 830 and / or the column 828. For example, the appendages 832a, 832b may be arranged in parallel so that the channel 834 has a uniform width from the center to the end. In some embodiments, the width of the appendages 832a, 832b is greater than the width of the column 828, so that the user can more easily guide the column 828 and / or the blade 830 toward the bracket 810 and / or the extension 812. In some embodiments, the appendages 832a, 832b may have an arc or crescent-shaped structure, wherein the end of the structure extends inwardly to prevent the column 828 from accidentally sliding out of the channel 834. In some embodiments, the appendages 832a, 832b may have a straight, arc or crescent-shaped structure, wherein the end of the structure extends outwardly to form a tapered channel 834, so that the column 828 is more easily introduced into the channel 834. In some embodiments, the appendages 832a and 832b may form a closed ring structure, so that the channel 834 forms a guide mechanism, allowing the blade 830 to be guided along the channel to the bracket 810 and accurately cut off the connection between the bracket 810 and the extension 812. The appendages 832a and 832b may adopt any appropriate configuration to ensure that the channel 834 can effectively receive the blade 830 and / or the column 828.

[0069] The handle 826 is used to provide a component that enables the user to manually operate the cutter 824. The handle 826 can have any suitable configuration to assist in operating the cutter 824. For example, the handle 826 can be round, square, triangular, or any shape suitable for the user to hold. In some embodiments, the handle 826 can include a rubber or non-slip textured portion to improve the user's grip on the cutter 824.

[0070] The post 828 is used to provide leverage to allow the blade 830 to penetrate the extension 812 and separate the bracket 810 from the support 808. The post 828 can have any suitable length to help provide leverage to the cutter 824 and enable the user to operate the cutter 824 in the user's mouth. The post 828 can have any shape and extend between the blade 830 and the handle 826, such as cylindrical, square, rectangular, or any other suitable shape. In some embodiments, the post 828 can also serve as the handle 826, and the dental device 800 does not include such a post. Figure 8 The handle 826 is shown. The post 828 can be of sufficient length to allow a user to grasp the post 828 and / or the handle 826 and rotate the blade 830 relative to the bracket 810 to cut the bracket 810 away from the extension 812 without interference from one or more teeth 802.

[0071] The blade 830 is used to directly contact and separate the bracket 810 from the extension 812 of the dental device 800. The blade 830 can have any suitable configuration to cut the bracket 810 and separate it from the extension 812. For example, the blade 830 can have a disc-shaped, square, triangular, rectangular, or any combination thereof. The blade 830 can be made of any suitable material to separate the extension 812 from the bracket 810. The blade 830 can be made of a variety of materials or components to provide leverage when cutting and effectively separate the extension 812 from the bracket 810. For example, the blade 830 can be made of diamond, stainless steel, tungsten carbide, satellite alloy, ceramic, cubic boron nitride, or any combination thereof. The blade 830 can be sharpened to an appropriate angle to effectively cut the extension 812 so that no excess portion of the extension 812 remains on the bracket 810, thereby avoiding the use of grinding, polishing or other additional processing techniques to remove excess material.

[0072] Fig.9A A perspective view of a dental device 900 is shown, which can be used with Figures 1 to 3 5 to 8 are similar to the dental devices 100, 200, 300, 500, 600, 700, 800 shown in FIG. Fig. 9B A perspective view of dental apparatus 900 is shown, presenting an enlarged view of bracket 910 coupled to support 908 . Fig. 9C is a cross-sectional view of a dental device 900, showing that the device can be used with a drill 924, which can be used with Figure 8 The cutter 824 shown has a similar function.

[0073] The dental device 900 includes a support 908 connected to a bracket 910 via an extension 912. The support 908 can be connected to the bracket 910. Figures 1 to 8The support members 108, 208, 308, 508, 708, 808 are similar to those shown; the bracket 910 can be similar to Figures 1 to 8 The brackets 110, 210, 310, 400, 510, 610, 710, 810 are similar; the extension 912 can be similar to Figures 1 to 8 The extensions 112, 212, 312, 512, 712, 812 are similar. The extension 912 is connected to the support member 908 by a beam 914, which can be connected to the support member 908. Figure 1 , 3 , 5, 7 and 8. The bracket 910 has at least one cutout 911, which can be similar to the cutout 406 shown in FIG. 4, and the bracket 910 is connected to the extension 912 by a guide 922. The guide 922 is used to guide a drill 924 to facilitate separation of the bracket 910 from the support 908. The guide 922 has an opening 932a, which is equal to or larger than the drill 924, and a subsequent opening 932b, which is equal to or smaller than the opening 932a, and equal to or smaller than the drill 924. When the drill bit 930 passes through the channel 934 defined by the openings 932a, 932b, the drill 924 will remove material from the guide 922 until the drill bit 930 contacts the terminal edge 936 of the guide 922.

[0074] When the drill bit 930 contacts, drills through or removes the terminal edge 936 or its adjacent position, the bracket 910 is separated from the guide 922. This configuration allows the user to accurately position the bracket 910 on the tooth 902 and separate the bracket 910 from the dental device 900 with high precision, reducing the risk of interference with other parts of the oral cavity and / or the dental device 900, and avoiding drilling into the channel 938, which can be connected to the tooth 902. Figures 4A to 4B The conduit 416 shown is similar.

[0075] A stopper 931 may be provided above the drill bit 930 of the drill 924 to prevent or reduce the drill bit 930 from drilling through the terminal edge 936 and entering the pipe 938. The stopper 931 may be larger than the opening 932a. In some embodiments, the drill 924 may not include the stopper 931. The width of the terminal edge 936 is smaller than the drill bit 930, so that when the drill bit 930 moves to contact the terminal edge 936 or a position adjacent to the terminal edge 936, the drill 924 can remove enough material to separate the bracket 910 from the guide 922.

[0076] The drill 924 can have any suitable configuration for separating the bracket 910 from the dental device 900. The drill 924 can be used to interact with one to ten openings 932a, 932b, and the width of the openings 932a, 932b can be gradually reduced to allow the user to smoothly guide from the top of the guide 922 to the terminal edge 936 of the guide 922. In some embodiments, the guide 922 can include an opening (not shown) that can have a tapered structure to guide the drill 924 toward the terminal edge 936. The drill 924 and its drill bit 930 can have any configuration known in the art that is suitable for drilling through organic and inorganic materials (such as metals, ceramics, polymer materials and / or composite materials). For example, the drill bit 930 can be inclined or pointed to make it easier for the drill bit 930 to be guided through a particular material and the openings 932a, 932b. In this specification, the term "drilling" is used interchangeably with "cutting" when describing the separation of the bracket 910 from the dental device 900.

[0077] The guide 922 may have any configuration sufficient to assist in drilling a hole from the top to the terminal edge 936 . Fig. 9C A tapered and / or stepped configuration is shown to allow the drill 924 to drill to a position that is wider than the terminal edge 936. Any configuration that allows the drill 924 to remove sufficient material to separate the bracket 910 and the guide 922 is suitable. In some configurations, the terminal edge 936 can be arranged along an axis coaxial with the channel 1034, so that the drill 924 can be guided along the openings 932a, 932b and the channel 934 directly to the terminal edge 936 to effectively separate the bracket 910 and the guide 922.

[0078] The channel 934 serves as a guide channel to accommodate the drill bit 930. The channel 934 may have any size or shape as long as it is sufficient to accommodate the corresponding drill 924. The size or length of the channel 934 may be appropriately designed so that the drill bit 930 can enter and remove the material of the guide 922 until the guide 922 is separated from the bracket 910 and almost no material remains on the bracket 910.

[0079] Fig.10 FIG. 1 is a perspective view of a transparent guide 1022, showing its positioning for drilling by a drill 1024. The guide 1022 and the drill 1024 may be similar to Figures 9A to 9C The guide 922 and the drill 924 are shown. The drill 1024 includes a drill bit 1030, which is used to interact with the guide 1022 and pass through the openings 1032a, 1032b to drill toward the terminal edge 1036 of the guide 1022. The openings 1032a, 1032b, the drill bit 1030 and the terminal edge 1036 can be similar to Figures 9A to 9CThe openings 932a, 932b, the drill bit 930 and the terminal guide edge 936 are shown. Fig.10 As shown, the second opening 1032b is separated from the terminal edge 1036 by a solid portion of the guide 1022. The drill 1024 is used to penetrate the guide 1022 and remove material during the drilling process. The drill 1024 includes a stopper 1031, which is disposed on the drill bit 1030 and can be similar to Figures 9A-9C The stopper 931 is shown and is used to prevent the drill bit 1030 from drilling too deep and avoiding contact with one or more brackets (e.g., Figures 9A to 9C The bracket 910 shown may have an unintended interaction.

[0080] The openings 1032a, 1032b define a channel 1034, which may have any suitable configuration to guide the drill 1024 through the guide 1022 and toward the terminal edge 1036 of the adjacent bracket (not shown). For example, the openings 1032a, 1032b defining the channel 1034 may have a sufficient width to interact with the drill bit 1030. The width of the first opening 1032a may be similar to the width of the drill bit 1030 (with a difference of 1-100 microns). The width of the second opening 1032b may be less than the width of the drill bit 1030, so that the drill bit 1030 can remove material at the second opening 1032b and guide it to the terminal edge 1036. The guide 1022 may include a plurality of openings 1032a, 1032b to ensure that the drill 1024 can be effectively guided to the terminal edge 1036.

[0081] The terminal edge 1036 can have an appropriate width to allow the drill 1024 to separate the guide 1022 from the bracket (not shown). For example, the width of the terminal edge 1036 can be the same as or less than the width of the drill bit 1030. The terminal edge 1036 can be connected to the bracket (not shown) by any suitable means, such as by an adhesive or welding. In some embodiments, the guide 1022 and the bracket (not shown) can be integrally formed and can be manufactured by techniques described herein or known in the art. In some embodiments, the bracket (not shown) and the guide 1022 can be simultaneously formed by a 3D printing process.

[0082] The present disclosure provides a mechanism that can be directly combined with a brace, which can selectively include pre-threading of an archwire in a bracket and / or a dental device, and can be applied quickly and efficiently. A dental device is provided that can be placed on a tooth and pre-positions a bracket adjacent to a target tooth, so that a person applying the brace can quickly and one by one apply the bracket to the corresponding teeth. When all brackets are fixed on the teeth and are still connected to the support by an extension, the operator can further adjust the individual position of each bracket on the tooth to the desired position. When the operator confirms that each bracket has been adjusted to the appropriate position, the bracket can be separated from the extension by combining and / or cutting. The present technology can significantly shorten the time it takes to apply a brace and an archwire to a tooth, and allows the operator to place all brackets at the approximate target position of the tooth at one time, without having to take them out one by one from an external tray or container and apply them separately.

[0083] Although the present disclosure is described in conjunction with specific embodiments, the present disclosure is not limited to the disclosed embodiments. On the contrary, the present disclosure is intended to cover various modifications and equivalent designs falling within the scope of the appended claims, and should be interpreted in the broadest sense to cover all legally permitted modifications and equivalent structures.
