Description

Technical Field

[0002] Orthodontic appliances made of polymer materials are becoming more and more popular due to their advantages of beauty, convenience and ease of cleaning. Generally, orthodontic treatment using orthodontic appliances requires a series of orthodontic appliances, and the geometry of the cavity of each of these orthodontic appliances that accommodates the teeth basically matches the tooth layout that is desired to be achieved in the corresponding treatment step.

[0003] In many cases, it is difficult to ensure that a corrective force system of appropriate size and direction is applied to the teeth by relying solely on the dental orthodontic appliance itself. For example, in order to achieve functions such as pushing molars distally, closing tooth gaps, lowering teeth, guiding the mandible forward, and opening the bite, current dental orthodontic appliances include an appliance body that accommodates the teeth and accessories coupled to the appliance body. The accessories may include magnets that utilize the magnets to generate effective corrective force, but the magnets in the prior art are inconvenient to assemble. Utility Model Content

[0045] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0046] Combination Figures 1 to 7 , which is a schematic diagram of a dental orthodontic appliance assembly 200 according to an embodiment of the present invention.

[0047] The dental orthodontic appliance assembly 200 includes two groups of dental orthodontic appliances 100 (specifically, a first dental orthodontic appliance 100a and a second dental orthodontic appliance 100b), each group of dental orthodontic appliances 100 includes an appliance body 10 (specifically, a first appliance body 10a and a second appliance body 10b) and a magnetic component 20 (specifically, a first magnetic component 20a and a second magnetic component 20b) installed on the appliance body 10.

[0048] Here, the appliance body 10 has a cavity for accommodating teeth, that is, the appliance body 10 is an invisible appliance made of polymer material.

[0049] Specifically, the two sets of dental orthodontic appliances 100 include a first dental orthodontic appliance 100a and a second dental orthodontic appliance 100b. The first dental orthodontic appliance 100a includes a first appliance body 10a and a first magnetic component 20a installed on the first appliance body 10a. The second dental orthodontic appliance 100b includes a second appliance body 10b and a second magnetic component 20b installed on the second appliance body 10b.

[0050] In this embodiment, the first orthodontic appliance body 10a and the second orthodontic appliance body 10b can be set in the same jaw, and the first orthodontic appliance body 10a and the second orthodontic appliance body 10b are disconnected from each other. The first orthodontic appliance body 10a can cover multiple teeth, and the second orthodontic appliance body 10b can cover other teeth located in the same jaw, so that the teeth to be corrected are not only subject to the correction force generated by the first orthodontic appliance body 10a and the second orthodontic appliance body 10b, but also subject to the correction force generated by the interaction between the first magnetic component 20a and the second magnetic component 20b. At this time, when the first magnetic component 20a and the second magnetic component 20b interact with each other to generate the correction force, the correction force can be transmitted to the corresponding teeth in the same jaw through the first orthodontic appliance body 10a and the second orthodontic appliance body 10b, thereby realizing the adjustment of the tooth position, such as realizing the distal movement of the molars and the closing of the tooth gap.

[0051] Alternatively, the first orthodontic appliance body 10a and the second orthodontic appliance body 10b are respectively arranged corresponding to the maxillary teeth and the mandibular teeth, the first orthodontic appliance body 10a has a cavity matching the maxillary teeth, the second orthodontic appliance body 10b has a cavity matching the mandibular teeth, the first magnetic component 20a is arranged corresponding to the maxillary teeth, and the second magnetic component 20b is arranged corresponding to the mandibular teeth, the first magnetic component 20a and the second magnetic component 20b interact with each other to generate a correction force, so that the teeth to be corrected are not only affected by the correction force generated by the first orthodontic appliance body 10a and the second orthodontic appliance body 10b, but also by the correction force generated by the interaction between the first magnetic component 20a and the second magnetic component 20b. At this time, when the first magnetic component 20a and the second magnetic component 20b interact with each other to generate the correction force, the correction force can be transmitted to the maxillary teeth and the mandibular teeth through the first orthodontic appliance body 10a and the second orthodontic appliance body 10b, so as to achieve the adjustment of the maxillary teeth and the mandibular teeth, such as lowering the teeth, guiding the mandible forward, opening the bite, etc.

[0052] In this embodiment, each appliance body 10 includes a mounting surface 11 , and the mounting surface 11 may be located on the buccal surface A1 , the lingual surface A2 , or the occlusal surface A3 of the appliance body 10 .

[0053] The magnetic component 20 includes a detachably connected base 21 and a magnetic member 22. The base 21 is fixed to the mounting surface 11, and the magnetic member 22 includes a first mating portion 221. The base 21 includes a second mating portion 211. When the magnetic member 22 is inserted into the base 21, the first mating portion 221 and the second mating portion 211 are engaged with each other.

[0054] That is to say, in this embodiment, the assembly between the magnetic part 22 and the base 21 is achieved by inserting the magnetic part 22 into the base 21, and the mutual fixation between the magnetic part 22 and the base 21 is achieved by the mutual snap connection between the first matching part 221 and the second matching part 211. It can be seen that the assembly and fixation between the magnetic part 22 and the base 21 can be achieved only by insertion and snap connection. The assembly process of the magnetic component 20 is relatively simple and convenient, and the fixing effect is better. In addition, the magnetic component 20 of this structure can also be easily disassembled, thereby facilitating the replacement of the magnetic part 22.

[0055] In this embodiment, the mounting surface 11 is a plane, which can facilitate the installation of the magnetic component 20 on the mounting surface 11 , but the present invention is not limited thereto.

[0056] In a specific embodiment, the base 21 and the mounting surface 11 are planarly matched, that is, the side of the base 21 close to the mounting surface 11 is a plane, and the base 21 and the mounting surface 11 are fixed to each other by filling with colloid.

[0057] In another specific embodiment, the magnetic component 20 includes a matching portion 50 located on the base 21, and the orthodontic appliance body 10 includes a mounting portion 51 located on the mounting surface 11 and matched with the matching portion 50, one of the matching portion 50 and the mounting portion 51 is a convex column, and the other is a groove, Figure 2 and Figure 4 The matching portion 50 is a groove located on the base 21 , and the mounting portion 51 is a convex column located on the mounting surface 11 .

[0058] That is to say, the stable fit between the mounting surface 11 and the base 21 is achieved through the fit of the boss and the groove, thereby preventing the base 21 from shifting relative to the mounting surface 11 of the appliance body 10. At this time, a colloid can also be filled between the boss and the groove.

[0059] Of course, microstructures that increase friction may also be formed on the base 21 or the mounting surface 11 . When the colloid is filled, the microstructures may improve the bonding reliability, thereby further improving the stability of the fit between the base 21 and the mounting surface 10 .

[0060] In addition, combined Figure 5 The magnetic component 22 includes a magnet 222 and a packaging structure 223 that wraps the magnet 222 .

[0061] Specifically, the packaging structure 223 is a plastic part, and the magnet 222 is completely wrapped in the packaging structure 223 by injection molding or other methods, so as to achieve the purpose of completely isolating the magnet 222 from direct contact with the oral cavity.

[0062] In this embodiment, the magnetic assembly 20 is configured as follows: the magnetic member 22 is inserted into the base 21 along a first direction or a second direction, the first direction is parallel to the mounting surface 11 , and the second direction is perpendicular to the mounting surface 11 .

[0063] That is to say, according to the installation surface 11 in different positions or different correction requirements, etc., a suitable removal direction can be selected to facilitate plugging and unplugging.

[0064] Several specific embodiments of the dental orthodontic appliance assembly 200 are introduced below.

[0065] Combination Figures 1 to 7 , is a schematic diagram of a dental orthodontic appliance assembly 200 according to a first specific embodiment.

[0066] In this specific embodiment, the magnetic member 22 includes a first matching portion 221, and the base 21 includes a second matching portion 211. The first matching portion 221 and / or the second matching portion 211 are deformable structures. When the magnetic member 22 is inserted into the base 21, the first matching portion 221 and / or the second matching portion 211 are deformed so that the first matching portion 221 and the second matching portion 211 are mutually engaged.

[0067] Here, “the first matching portion 221 and / or the second matching portion 211 is a deformable structure” means that the first matching portion 221 is a deformable structure and the second matching portion 211 is not deformable, or the second matching portion 211 is a deformable structure and the first matching portion 221 is not deformable, or both the first matching portion 221 and the second matching portion 211 are deformable structures.

[0068] The deformable structure of this specific embodiment is a structure that can be reset after deformation. When the magnetic member 22 is inserted into the base 21, the first matching portion 221 and / or the second matching portion 211 are deformed to allow the magnetic member 22 to enter the base 21. Then, the deformed first matching portion 221 and / or the second matching portion 211 are reset to achieve mutual clamping between the first matching portion 221 and the second matching portion 211, and at the same time, the mutual fixation of the magnetic member 22 and the base 21 is achieved. It can be seen that the mutual clamping between the first matching portion 221 and the second matching portion 211 can be easily achieved through the deformation of the first matching portion 221 and / or the second matching portion 211.

[0069] Of course, in other specific embodiments, the deformable structure may also be a structure that cannot be reset after deformation, that is, after the first matching portion 221 and / or the second matching portion 211 are deformed, the first matching portion 221 and the second matching portion 211 are directly connected to each other.

[0070] In this specific embodiment, the base 21 includes a receiving groove 212, and the receiving groove 212 includes an insertion port 2121. When the magnetic component 22 is inserted into the receiving groove 212 through the insertion port 2121, the first matching portion 221 and / or the second matching portion 211 are deformed so that the magnetic component 22 enters the receiving groove 212, and the first matching portion 221 and the second matching portion 211 are mutually engaged to limit the magnetic component 22 from leaving the receiving groove 212.

[0071] In addition, the magnetic component 22 also includes a first limiting portion 224, and the base 21 also includes a second limiting portion 213. When the magnetic component 22 is located in the receiving groove 212, the first limiting portion 224 and the second limiting portion 213 cooperate with each other to at least limit the movement of the magnetic component 22 relative to the receiving groove 212 in the displacement direction, and the first matching portion 221 and the second matching portion 211 are mutually engaged to at least limit the movement of the magnetic component 22 relative to the receiving groove 212 in the extraction direction. One of the displacement direction and the extraction direction is the first direction X, and the other is the second direction Y. The first direction X is parallel to the mounting surface 11, and the second direction Y is perpendicular to the mounting surface 11.

[0072] Here, there are two groups of matching structures between the magnetic part 22 and the base 21. The first group of matching structures is the first limiting portion 224 and the second limiting portion 213, and the second group of matching structures is the first matching portion 221 and the second matching portion 211. The first group of matching structures limits the movement of the magnetic part 22 relative to the receiving groove 212 in the displacement direction, and the second group of matching structures limits the movement of the magnetic part 22 relative to the receiving groove 212 in the extraction direction. The extraction direction is the direction in which the magnetic part 22 leaves the receiving groove 212, and the displacement direction is other directions different from the extraction direction.

[0073] It can be seen that the relative movement of the magnetic member 22 and the receiving groove 212 in the displacement direction and the extraction direction is restricted. What is actually restricted is the relative movement of the magnetic member 22 and the receiving groove 212 in the first direction X (the direction parallel to the mounting surface 11) and the second direction Y (the direction perpendicular to the mounting surface 11). The relative movement of the magnetic member 22 and the receiving groove 212 in each free direction can be restricted by two sets of matching structures. In this way, the absolute fixation between the magnetic member 22 and the receiving groove 212 can be achieved, and the magnetic member 22 will not move relative to the receiving groove 212, thereby improving the stability of the correction force generated between the two magnetic members 22.

[0074] Of course, in other specific embodiments, the two sets of matching structures can also be integrated, that is, the first limiting portion 224 and the first matching portion 221 are the same structure, and the second limiting portion 213 and the second matching portion 211 are the same structure, and the magnetic part 22 is directly limited from moving relative to the accommodating groove 212 in the first direction X and the second direction Y through the clamping connection between the first matching portion 221 and the second matching portion 211.

[0075] Continue to combine Figures 1 to 7 In this specific embodiment, the displacement direction is the first direction X, and the pull-out direction is the second direction Y, that is, the magnetic member 22 is inserted into the receiving groove 212 along a direction perpendicular to the mounting surface 11. When the magnetic member 22 is located in the receiving groove 212, the first matching portion 221 and the second matching portion 211 at least limit the movement of the magnetic member 22 relative to the receiving groove 212 in a direction perpendicular to the mounting surface 11 (specifically, a direction away from the mounting surface 11), and the first limiting portion 224 and the second limiting portion 213 at least limit the movement of the magnetic member 22 relative to the receiving groove 212 in a direction parallel to the mounting surface 11.

[0076] Specifically, the base 21 includes a bottom plate 214 fixed to the mounting surface 11 and a side plate 215 disposed around the bottom plate 214 . The bottom plate 214 and the side plate 215 surround and form a receiving groove 212 .

[0077] The first limiting portion 224 is two recessed portions 224 located on opposite sides of the magnetic member 22, the second limiting portion 213 is two protrusions 213 protruding out of the side plate 215 toward the receiving groove 212, the first matching portion 221 is the magnetic member surface 221 connecting the two recessed portions 224, and the second matching portion 211 is two claw portions 211 of the two protrusions 213 protruding out toward the receiving groove 212.

[0078] At this time, the magnetic member 22 is roughly a waisted structure in the middle, the base 21 is roughly an open structure, and the outer contour of the magnetic member 22 is roughly the same as the shape of the receiving groove 212 to further limit the movement of the magnetic member 22 in the receiving groove 212.

[0079] When the magnetic component 22 is located in the receiving groove 212, the two protrusions 213 are respectively limited to the two recessed portions 224 to at least limit the movement of the magnetic component 22 relative to the receiving groove 212 in a direction parallel to the mounting surface 11, and the two claw portions 211 abut against the magnetic component surface 221 to at least limit the movement of the magnetic component 22 relative to the receiving groove 212 in a direction perpendicular to the mounting surface 11 (specifically, the direction away from the mounting surface 11).

[0080] Here, the width of the magnetic component surface 221 located between the two recessed portions 224 is greater than the opening width of the two claw portions 211. When the magnetic component 22 is inserted into the receiving groove 212 from the insertion port 2121, only the two claw portions 211 are deformed to allow the magnetic component 22 to enter the receiving groove 212, and then the two claw portions 211 are reset and abut against the magnetic component surface 221, or the two claw portions 211 are not reset but directly interference fit with the magnetic component surface 221 to limit the movement of the magnetic component 22.

[0081] The insertion process of the magnetic part 22 is exactly the process of the two protrusions 213 matching with the two recessed parts 224, which can realize the limitation in multiple directions at the same time. At this time, the two sets of matching structures are arranged together, which can reduce the problem that the two sets of matching structures cannot be fully matched at the same time due to the separate arrangement of the two sets of matching structures. In this way, the precision requirements of the two sets of matching structures are reduced.

[0082] In addition, when the magnetic member 22 is located in the receiving groove 212 , the surface of the magnetic member 22 away from the mounting surface 11 is substantially flush with the surface of the side plate 215 away from the mounting surface 11 , thereby preventing the oral mucosa from being irritated by the unevenness of the entire magnetic assembly 20 .

[0083] In this specific embodiment, the receiving groove 212 further includes a through opening 2122 . The insertion opening 2121 is located at a side of the receiving groove 212 away from the bottom plate 214 . The through opening 2122 is adjacent to and connected to the insertion opening 2121 .

[0084] Here, "the through opening 2122 is adjacent to and connected to the insertion opening 2121" means that the opening directions of the insertion opening 2121 and the through opening 2122 are perpendicular to each other, and the through opening 2122 and the insertion opening 2121 are connected to each other. At this time, the side panel 215 surrounds the bottom panel 214 on three sides, and the other side of the side panel 215 and the top surface away from the bottom panel 214 are the through opening 2122 and the insertion opening 2121 respectively.

[0085] That is to say, the receiving groove 212 at this time has openings in a direction parallel to the mounting surface 11 and a direction perpendicular to the mounting surface 11 .

[0086] When the magnetic component 22 is located in the receiving groove 212, the magnetic component 22 passes through the through opening 2122 and extends out of the bottom plate 214, that is, at this time the bottom plate 214 only supports a portion of the magnetic component 22, and another portion of the magnetic component 22 protrudes out of the bottom plate 214. The portion protruding out of the bottom plate 214 can facilitate the user to apply force to remove the magnetic component 22 from the receiving groove 212.

[0087] In this specific embodiment, the magnetic component 20 is installed on the occlusal surface A3 of the appliance body 10, the first direction X is the mesiodistal direction, and the second direction Y is the direction away from the occlusal surface A3.

[0088] Specifically, the dental orthodontic appliance assembly 200 includes two groups of dental orthodontic appliances 100 (specifically a first dental orthodontic appliance 100a and a second dental orthodontic appliance 100b), each group of dental orthodontic appliances 100 includes an appliance body 10 (specifically a first appliance body 10a and a second appliance body 10b) and a magnetic component 20 installed on the appliance body 10 (specifically a first magnetic component 20a and a second magnetic component 20b).

[0089] One of the first orthodontic body 10a and the second orthodontic body 10b is arranged corresponding to the maxillary teeth, and the other one is arranged corresponding to the mandibular teeth. Here, it is taken as an example that the first orthodontic body 10a is arranged corresponding to the maxillary teeth, and the second orthodontic body 10b is arranged corresponding to the mandibular teeth.

[0090] The first magnetic component 20a is located on the occlusal surface A3 of the first orthodontic device body 10a, and the second magnetic component 20b is located on the occlusal surface A3 of the second orthodontic device body 10b. When the maxillary teeth and the mandibular teeth are in a fully occluded state, the distal end face of the first magnetic component 20a faces the proximal end face of the second magnetic component 20b, so that suction or repulsion is generated between the first magnetic component 20a and the second magnetic component 20b. The suction or repulsion can realize the advancement or backward movement of the mandible, etc.

[0091] The first magnetic component 20a and the second magnetic component 20b are both located in the posterior tooth area of ​​the occlusal surface A3. In the direction away from the occlusal surface A3, the first magnetic component 20a has a first height, and the second magnetic component 20b has a second height. The first height tends to decrease in the direction away from the second magnetic component 20b, and the second height tends to decrease in the direction away from the first magnetic component 20a. The changing height can achieve avoidance of the posterior teeth.

[0092] Combination Figures 8 to 11 , is a schematic diagram of a dental orthodontic appliance assembly 200' of a second specific embodiment. For ease of explanation, the same or similar structures of the second specific embodiment and the first specific embodiment are numbered the same or similarly, hereinafter the same.

[0093] In this specific embodiment, the magnetic member 22' includes a first matching portion 221', and the base 21' includes a second matching portion 211'. The first matching portion 221' and / or the second matching portion 211' are deformable structures. When the magnetic member 22' is inserted into the base 21', the first matching portion 221' and / or the second matching portion 211' are deformed so that the first matching portion 221' and the second matching portion 211' are mutually engaged.

[0094] The base 21' includes a receiving groove 212', and the receiving groove 212' includes an insertion port 2121'. When the magnetic member 22' is inserted into the receiving groove 212' through the insertion port 2121', the first matching portion 221' and / or the second matching portion 211' are deformed so that the magnetic member 22' enters the receiving groove 212', and the first matching portion 221' and the second matching portion 211' are mutually engaged to limit the magnetic member 22' from leaving the receiving groove 212'.

[0095] In addition, the magnetic component 22' also includes a first limiting portion 224', and the base 21' includes a second limiting portion 213'. When the magnetic component 22' is located in the receiving groove 212', the first limiting portion 224' and the second limiting portion 213' cooperate with each other to at least limit the movement of the magnetic component 22' relative to the receiving groove 212' in the displacement direction, and the first matching portion 221' and the second matching portion 211' are mutually engaged to at least limit the movement of the magnetic component 22' relative to the receiving groove 212' in the extraction direction. One of the displacement direction and the extraction direction is the first direction X', and the other is the second direction Y'. The first direction X' is parallel to the mounting surface 11', and the second direction Y' is perpendicular to the mounting surface 11'.

[0096] Continue to combine Figures 8 to 11In the present specific embodiment, the displacement direction is the second direction Y', and the pull-out direction is the first direction X', that is, the magnetic member 22' is inserted into the receiving groove 212' along a direction parallel to the mounting surface 11'. When the magnetic member 22' is located in the receiving groove 212', the first matching portion 221' and the second matching portion 211' at least limit the movement of the magnetic member 22' relative to the receiving groove 212' in a direction parallel to the mounting surface 11', and the first limiting portion 224' and the second limiting portion 213' at least limit the movement of the magnetic member 22' relative to the receiving groove 212' in a direction perpendicular to the mounting surface 11'.

[0097] Specifically, the receiving groove 212' penetrates the base 21' along the extraction direction. Here, the receiving groove 212' penetrates two opposite side surfaces of the base 21' as an example, that is, the receiving groove 212' is a through groove in a direction parallel to the mounting surface 11'.

[0098] The first limiting portion 224' is the outer wall 224' of the magnetic member 22', the second limiting portion 213' is the inner wall 213' of the receiving groove 212', the first matching portion 221' is two protrusions 221' located on opposite sides of the magnetic member 22', and the second matching portion 211' is two notches 211' connected to the receiving groove 212'.

[0099] Here, the side of the receiving groove 212 ′ away from the mounting surface 11 ′ is a closed structure, that is, the base 21 ′ is substantially a hollow structure.

[0100] In addition, the first matching portion 221 ′ may be a recess, and the second matching portion 211 ′ may be a protrusion.

[0101] The inner contour dimension of the recess 211' is roughly equal to the outer contour dimension of the protrusion 221', which can achieve stable cooperation between the protrusion 221' and the recess 211', and when the recess 211' is located at the base 21', the recess 211' passes through the side of the base 21', that is, the recess 211' is a through opening connecting the accommodating groove 212' and the external area. When the protrusion 221' enters the recess 211', the user can directly observe it.

[0102] When the magnetic component 22' is located in the receiving groove 212', the inner wall 213' abuts against the outer wall 224' and at least limits the movement of the magnetic component 22' relative to the receiving groove 212' in a direction perpendicular to the mounting surface 11'. The two protrusions 221' are respectively limited to the two recesses 211' and at least limit the movement of the magnetic component 22' relative to the receiving groove 212' in a direction parallel to the mounting surface 11' (i.e., the pull-out direction).

[0103] Here, the maximum distance between the two protrusions 221' is greater than the opening width of the receiving groove 212'. When the magnetic member 22' is inserted into the receiving groove 212' from the insertion port 2121', only the two protrusions 221' are deformed so that the magnetic member 22' enters the receiving groove 212'. Then, when the two protrusions 221' reach the positions of the two recesses 211', the two protrusions 221' are reset and enter the two recesses 211' respectively.

[0104] In addition, when the magnetic component 22' is located in the receiving groove 212', the entire inner wall 213' of the receiving groove 212' wraps most of the outer wall 224' of the magnetic component 22', which can limit the movement of the magnetic component 22' relative to the receiving groove 212' in the direction perpendicular to the installation surface 11' and in the direction parallel to the installation surface 11' (up and down direction).

[0105] In this specific embodiment, the magnetic component 20 ′ is installed on the buccal surface A1 of the appliance body 10 ′, the first direction X′ is the mesiodistal direction, and the second direction Y′ is the direction perpendicular to the buccal surface A1 .

[0106] Specifically, the dental orthodontic appliance assembly 200' includes two groups of dental orthodontic appliances 100' (specifically a first dental orthodontic appliance 100a' and a second dental orthodontic appliance 100b'), each group of dental orthodontic appliances 100' includes an appliance body 10' (specifically a first appliance body 10a' and a second appliance body 10b') and a magnetic component 20' (specifically a first magnetic component 20a' and a second magnetic component 20b') installed on the appliance body 10'.

[0107] The first orthodontic body 10a' and the second orthodontic body 10b' are arranged on the same jaw, and the first orthodontic body 10a' and the second orthodontic body 10b' are disconnected from each other. At this time, the first orthodontic body 10a' and the second orthodontic body 10b' can be arranged adjacent to each other, or the first orthodontic body 10a' and the second orthodontic body 10b' can be arranged with a few teeth between them.

[0108] The first magnetic component 20a' is located on the buccal surface A1 of the first orthodontic device body 10a', and the second magnetic component 20b' is located on the buccal surface A1 of the second orthodontic device body 10b'. The proximal end surface of the first magnetic component 20a' faces the distal end surface of the second magnetic component 20b', so that suction or repulsion is generated between the first magnetic component 20a' and the second magnetic component 20b'. The suction or repulsion can achieve distal movement of molars, closing of tooth gaps, etc.

[0109] In another specific embodiment, in combination Fig.12One of the first orthodontic body 10a' and the second orthodontic body 10b' is arranged corresponding to the maxillary teeth, and the other one is arranged corresponding to the mandibular teeth. Here, it is taken as an example that the first orthodontic body 10a' is arranged corresponding to the maxillary teeth, and the second orthodontic body 10b' is arranged corresponding to the mandibular teeth.

[0110] The first magnetic component 20a' is located on the buccal surface A1 of the first orthodontic device body 10a', and the second magnetic component 20b' is located on the buccal surface A1 of the second orthodontic device body 10b'. When the maxillary teeth and the mandibular teeth are in a fully occluded state, the lower end surface of the first magnetic component 20a' faces the upper end surface of the second magnetic component 20b', so that suction or repulsion is generated between the first magnetic component 20a' and the second magnetic component 20b'. The suction or repulsion can achieve tooth depression, etc.

[0111] Of course, similar to that shown in the first embodiment, the magnetic component 20' of this embodiment may also be located on the occlusal surface A3 of the appliance body 10'. For details, please refer to the first embodiment and will not be described again.

[0112] For other descriptions of the second specific embodiment, reference may be made to other specific embodiments.

[0113] Combination Fig.13 and Fig.14 , is a schematic diagram of a dental orthodontic appliance assembly of a third specific embodiment.

[0114] In this specific embodiment, the magnetic member 22" includes a first matching portion 221", the base 21" includes a second matching portion 211", the first matching portion 221" includes a first slide rail 2211", and the second matching portion 211" includes a second slide rail 2111". When the magnetic member 22" is inserted into the base 21", the first slide rail 2211" slides into the second slide rail 2111".

[0115] That is to say, at this time, the first matching portion 221 ″ and the second matching portion 211 ″ are connected to each other by sliding matching, and the connecting form is simple and easy to operate.

[0116] In this specific embodiment, the magnetic member 22' includes a magnetic member body 225" and a first sliding portion 226", protruding from the magnetic member body 225", the base 21" includes a base body 216" and a second sliding portion 217", protruding from the base body 216", one of the first sliding portion 226" and the second sliding portion 217" includes a cavity S, the cavity S includes an edge line S1, and the other includes an outer edge S2, one of the first sliding rail 2211" and the second sliding rail 2111" is located on the edge line S1, and the other is located on the outer edge S2.

[0117] In this specific embodiment, the first sliding portion 226 ″ includes a cavity S, the first sliding rail 2211 ″ is located at the edge line S1 , and the second sliding rail 2111 ″ is located at the outer edge S2 .

[0118] That is to say, the first sliding portion 226" is a structure located at the bottom of the magnetic body 225", and the first sliding portion 226" forms a cavity S with a sliding entrance S3, the cavity S is a flat structure, and the edge line S1 of the cavity S refers to the physical area surrounding the cavity S. The first slide rail 2211" is located on the edge line S1, which means that the first slide rail 2211" faces the cavity S, and the first slide rail 2211" is connected to the sliding entrance S3.

[0119] The second sliding portion 217 ″ is a boss structure located on the top of the base body 216 ″. The boss structure includes an outer edge S2 , and the second slide rail 2111 ″ is located on the outer edge S2 .

[0120] At this time, when the second sliding portion 217 ″ slides into the first sliding portion 226 ″ from the sliding entrance S3 , the second sliding rail 2111 ″ and the first sliding rail 2211 ″ are engaged with each other.

[0121] Specifically, the first slide rail 2211" and the second slide rail 2111" are both U-shaped, the first matching portion 221" also includes a first engaging portion 2212" located at the end of the first slide rail 2211", and the second matching portion 211" also includes a second engaging portion 2112" located at the end of the second slide rail 2111". When the first slide rail 2211" completely slides into the second slide rail 2111", the first engaging portion 2212" and the second engaging portion 2112" are engaged with each other to at least limit the movement of the magnetic part 22" relative to the base 21" in the opposite direction of the sliding-in direction, the first slide rail 2211" and the second slide rail 2111" are engaged with each other to at least limit the movement of the magnetic part 22" relative to the base 21" in the displacement direction, the sliding-in direction is parallel to the mounting surface 11", and the displacement direction is perpendicular to the mounting surface 11".

[0122] Here, when the first slide rail 2211" completely slides into the second slide rail 2111", the U-shaped first slide rail 2211" is completely matched with the U-shaped second slide rail 2111", and the first slide rail 2211" cannot continue to slide relative to the second slide rail 2111". At this time, the first locking portion 2212" and the second locking portion 2112" at the end can limit the first slide rail 2211" from detaching from the second slide rail 2111 in the opposite direction of the sliding direction.

[0123] In addition, since the first slide rail 2211" and the second slide rail 2111" are engaged with each other in the direction perpendicular to the mounting surface 11", when the first slide rail 2211" completely slides into the second slide rail 2111", the first slide rail 2211" and the second slide rail 2111" are also mutually limited in the direction perpendicular to the mounting surface 11".

[0124] It should be noted that in other specific embodiments, the structures of the first sliding portion 226 ″ and the second sliding portion 217 ″ can be interchanged, that is, the bottom of the magnetic body 225 ″ forms a boss structure, and the top of the base body 216 ″ forms a cavity S.

[0125] In this specific embodiment, the magnetic component 20" is installed on the occlusal surface A3 of the orthodontic body, and the magnetic component 22" is inserted into the base 21" along the mesiodistal direction. For details, please refer to the settings in the first specific embodiment.

[0126] For other descriptions of the third specific embodiment, reference may be made to other specific embodiments.

[0127] Combination Figures 15 to 19 One embodiment of the present invention further provides a shell-shaped dental instrument assembly 300 .

[0128] The shell-shaped dental instrument assembly 300 includes two groups of shell-shaped dental instruments 30 (specifically, a first shell-shaped dental instrument 30a and a second shell-shaped dental instrument 30b), each group of shell-shaped dental instruments 30 includes a shell-shaped dental instrument body 31 (specifically, a first shell-shaped dental instrument body 31a and a second shell-shaped dental instrument body 31b) and a magnetic member 32 (specifically, a first magnetic member 32a and a second magnetic member 32b) installed on the occlusal surface A3 of the shell-shaped dental instrument body 31.

[0129] Specifically, the two groups of shell-shaped dental instruments 30 include a first shell-shaped dental instrument 30a and a second shell-shaped dental instrument 30b. The first shell-shaped dental instrument 30a includes a first shell-shaped dental instrument body 31a and a first magnetic component 32a installed on the first shell-shaped dental instrument body 31a. The second shell-shaped dental instrument 30b includes a second shell-shaped dental instrument body 31b and a second magnetic component 32b installed on the second shell-shaped dental instrument body 31b.

[0130] In this embodiment, the first shell-shaped dental instrument body 31a and the second shell-shaped dental instrument body 31b are respectively matched with the upper and lower teeth as an example. The first shell-shaped dental instrument body 31a has a cavity that matches the upper teeth, and the second shell-shaped dental instrument body 31b has a cavity that matches the lower teeth. The first magnetic component 32a is set corresponding to the upper teeth, and the second magnetic component 32b is set corresponding to the lower teeth. The first magnetic component 32a and the second magnetic component 32b interact with each other to generate a correction force, so that the teeth to be corrected are not only affected by the correction force generated by the first shell-shaped dental instrument body 31a and the second shell-shaped dental instrument body 31b, but also by the correction force generated by the interaction between the first magnetic component 32a and the second magnetic component 32b.

[0131] That is to say, the first magnetic piece 32a is added to the first shell-shaped dental instrument body 31a and worn together on the maxillary teeth, and the second magnetic piece 32b is added to the second shell-shaped dental instrument body 31b and worn together on the mandibular teeth. When the first magnetic piece 32a and the second magnetic piece 32b interact with each other to generate corrective force, the corrective force can be transmitted to the maxillary teeth and the mandibular teeth through the first shell-shaped dental instrument body 31a and the second shell-shaped dental instrument body 31b, thereby achieving jaw position adjustment of the maxillary teeth and the mandibular teeth, for example, correcting skeletal Class III deformity.

[0132] The occlusal surface A3 of each shell-shaped dental instrument body 31 is provided with an assembly surface A31 , the magnetic member 32 is fixed to the assembly surface A31 , and the magnetic member 32 includes a fixing surface 321 of the assembly surface A31 .

[0133] In this embodiment, combined with Figures 15 to 19 The shell-shaped dental instrument 30 includes a first adapter portion 40 located on the assembly surface A31 and a second adapter portion 41 located on the fixing surface 321 and matched with the first adapter portion 40. One of the first adapter portion 40 and the second adapter portion 41 is a boss, and the other is a recess.

[0134] Here, taking the example that the first adapter part 40 is a boss and the second adapter part 41 is a recess, the stable fit between the assembly surface A31 and the fixing surface 321 can be achieved through the cooperation of the boss and the recess, avoiding displacement of the magnetic member 32 relative to the occlusal surface A3 of the shell-shaped dental instrument body 31.

[0135] In addition, a feature part 324 for increasing friction is provided on the assembly surface A31 or the fixing surface 321. When a colloid is filled between the assembly surface A31 and the fixing surface 321 to achieve fixation, the feature part 324 can improve the bonding reliability, thereby further improving the stability of the fit between the magnetic part 32 and the occlusal surface A3.

[0136] In this embodiment, the magnetic member 32 includes a magnet 325 and a packaging structure 326 encapsulating the magnet 325 .

[0137] Specifically, the packaging structure 326 is a plastic part, and the magnet 325 is completely wrapped in the packaging structure 326 by injection molding or other methods, so as to achieve the purpose of completely isolating the magnet 325 from direct contact with the oral cavity.

[0138] In this embodiment, the first magnetic member 32a is located on the occlusal surface A3 of the first shell-shaped dental instrument body 31a, and the second magnetic member 32b is located on the occlusal surface A3 of the second shell-shaped dental instrument body 31b. When the maxillary teeth and the mandibular teeth are in a fully occluded state, the distal end surface of the first magnetic member 32a faces the proximal end surface of the second magnetic member 32b, so that an attraction or repulsion force is generated between the first magnetic member 32a and the second magnetic member 32b. The attraction or repulsion force can realize the advancement or backward movement of the mandible, etc.

[0139] The first magnetic component 32a and the second magnetic component 32b are both located in the posterior tooth area of ​​the occlusal surface A3. In the direction perpendicular to the occlusal surface A3, the first magnetic component 32a has a first height, and the second magnetic component 32b has a second height. The first height tends to decrease in the direction away from the second magnetic component 32b, and the second height tends to decrease in the direction away from the first magnetic component 32a. The changing height can achieve avoidance of the posterior teeth.

[0140] To sum up, the utility model realizes the assembly between the magnetic part 22 and the base 21 by inserting the magnetic part 22 into the base 21, and realizes the mutual fixation between the magnetic part 22 and the base 21 by the mutual snap connection between the first matching part 221 and the second matching part 211. It can be seen that the assembly and fixation between the magnetic part 22 and the base 21 can be realized only by insertion and snap connection. The assembly process of the magnetic component 20 is relatively simple and convenient, and the fixing effect is better. In addition, the magnetic component 20 of this structure can also be easy to disassemble, which facilitates the replacement of the magnetic part 22.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0142] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
