Description

Technical Field

[0001] The present invention relates to the field of dental correction, and in particular to an upper invisible brace, a J hook matched with the upper invisible brace, and an invisible correction J hook system having the upper invisible brace. Background Art

[0002] Bracketless invisible orthodontic technology is relative to traditional fixed orthodontic technology. Its braces are made of medical resin diaphragm. There are no correction devices such as bands, brackets, archwires, etc. of fixed orthodontic appliances, so it is called "bracketless". The braces made of transparent resin diaphragm are not easily detected when worn in the mouth, so they are called "invisible". Bracketless invisible orthodontic appliances achieve the purpose of tooth correction through continuous small-range tooth movement. Compared with traditional orthodontic appliances, bracketless invisible orthodontic appliances have many advantages such as beautiful appearance, comfort, and good oral hygiene maintenance.

[0003] However, for the functional correction of early adolescent malocclusion, such as excessive vertical development of the anterior maxillary bone and deep overbite, the J hook can be used to assist in correction compared to traditional braces. It is difficult to achieve the correction goal by simply relying on bracketless invisible braces. Due to the limitations of the molding process of bracketless invisible braces, it is difficult to directly introduce extraoral forces into the bracketless invisible braces system, and it is difficult to organically combine the J hook with the bracketless invisible braces.

[0004] Chinese invention patent application CN112057187A discloses a vertically controllable leading invisible brace, comprising an invisible brace and a head cap with a J hook; the invisible brace comprises upper and lower invisible braces; positioning slots are respectively arranged on the left and right sides of the maxillary invisible brace near the mesial, and pull rings, traction protrusions or traction incisions are respectively arranged on the left and right sides of the maxillary invisible brace near the mesial; positioning blocks convex upwards are respectively arranged on the left and right sides of the mandibular invisible brace near the mesial; the left J hook is hooked on the pull ring, traction protrusion or traction incision on the left side of the maxillary invisible brace, and the right J hook is hooked on the pull ring, traction protrusion or traction incision on the right side of the maxillary invisible brace. The following defects exist in actual use:

[0005] (1) Making a traction incision at the edge of the invisible braces can form a hookable shape, but this method destroys the continuity of the edge of the invisible braces, reduces the area of ​​the invisible braces wrapped around the teeth, and indirectly affects the correction effect; at the same time, because the traction force acts directly on the traction incision, it will cause the edge of the traction incision to curl up, which not only causes the invisible braces to deform and affect the correction effect, but also easily causes damage to the patient's oral mucosa.

[0006] (2) A pull ring, a traction protrusion and other traction devices are installed on the invisible braces, and the J hook is pulled on the pull ring and the traction protrusion on the right side of the maxillary invisible braces. However, due to the structural limitations of this traction method, the contact surface between the J hook and the pull ring, the traction protrusion and between the pull ring, the traction protrusion and the invisible braces is relatively small, and most of the contacts are single-point or linear, which can easily cause the invisible braces to be locally subjected to excessive force and deform, resulting in unintended correction effects on other teeth, affecting the final correction effect; therefore, in order to avoid deformation of the maxillary invisible braces while applying force to the maxillary anterior teeth, the Chinese invention patent application CN112057187A increases the thickness of the bottom part of the maxillary invisible braces. However, increasing the thickness of the bottom part of the maxillary invisible braces not only increases the foreign body sensation in the mouth, but also the uneven thickness of the maxillary invisible braces affects the original correction effect of the maxillary invisible braces on the maxillary teeth, which may cause unintended correction effects. In addition, when traction is performed through a columnar traction protrusion, the traction protrusion is easily tilted due to force. After the traction protrusion is tilted, it will act on the bracketless invisible braces, which may easily cause the bracketless invisible braces to deform and cause adverse effects on other teeth.

[0007] (3) The J hook is connected through a traction incision, a pull ring, and a traction protrusion. The J hook is hooked on the traction incision, the pull ring, or the traction protrusion. The traction incision, the pull ring, or the traction protrusion cannot position the force direction of the J hook. The force direction of the J hook acting on the bracketless invisible braces can only be adjusted by adjusting the connection position between the J hook and the high-position traction head cap; however, the high-position traction head cap may still become loose when worn on the patient's head, making it difficult to accurately control the force direction of the extraoral traction force of the J hook. Summary of the invention

[0008] The present invention aims to solve at least one of the technical problems raised in the above-mentioned background technology, and provides an invisible orthodontic J-hook system, which can combine the J-hook with the maxillary invisible braces to achieve traction.

[0009] In order to achieve the above object, the technical solution adopted by the present invention is:

[0010] A J-hook system for invisible corrections comprises an invisible maxillary brace and a J-hook, wherein a bag-shaped structure is provided on the buccal side of the anterior teeth region of the invisible maxillary brace, wherein a receiving cavity is provided in the bag-shaped structure, wherein the receiving cavity passes through one side of the bag-shaped structure to form a bag opening, wherein the bag opening faces the anterior teeth region of the mandible; wherein the J-hook comprises a J-shaped hook body and a reinforcement block, wherein the reinforcement block is connected to the inner end of the J-shaped hook body, and wherein the reinforcement block is detachably plugged into the receiving cavity through the bag opening.

[0013] Further, the bag-shaped structure is a hollow quadrangular prism structure, including two parallel and oppositely arranged bottom plates, an end plate and two opposite inclined plates, the bottom plate is in the shape of an isosceles trapezoid, the end plate and the inclined plate are both rectangular, the end plate is connected to the upper bottom edge of the bottom plate, the two inclined plates are inclined and respectively connected to the two inclined edges of the trapezoidal bottom plate, the bottom plate, the end plate and the inclined plate together surround the receiving cavity, and one end of the bottom plate away from the end plate and one end of the inclined plate away from the end plate together surround the bag opening; one of the bottom plates is fixedly bonded to the buccal side of the maxillary invisible braces;

[0014] The reinforcing block is a quadrangular prism structure that is plugged into the bag-shaped structure, including two parallel and opposite bottom surfaces, two parallel and opposite end surfaces and two opposite inclined surfaces. The bottom surface is an isosceles trapezoidal shape, and the end surfaces and the inclined surfaces are both rectangular. One of the end surfaces is connected to the lower bottom edge of the bottom surface, and the other end surface is connected to the upper bottom edge of the bottom surface. The two inclined surfaces are inclined and respectively connected to the two inclined edges of the bottom surface. The inner end of the J hook is buried in the end with a larger cross-section of the reinforcing block. When the reinforcing block is plugged into the accommodating cavity, the end surface with a smaller cross-section of the reinforcing block can be against the inner wall of the end plate, and the two inclined surfaces can respectively contact the inner walls of the two inclined plates in parallel.

[0015] Furthermore, the hole wall surrounding the receiving cavity has a first inclined portion so that the cross-sectional area of ​​the receiving cavity gradually decreases in the direction away from the bag opening; the reinforcing block has a second inclined portion, and the second inclined portion can be in parallel contact with the first inclined portion.

[0016] Furthermore, the bag-shaped structure and the reinforcement block are both made of resin, and the reinforcement block includes a main body and a buffer part that are connected to each other. The main body is made of hard resin, and the buffer part is made of soft lining resin. The buffer part is located at one end of the reinforcement block that is inserted into the accommodating cavity, and the buffer part can elastically offset the bag-shaped structure; the inner end of the mouth of the J-shaped hook body is connected to the main body.

[0017] Further, the pocket-shaped structure extends from the maxillary lateral incisor region to the canine region.

[0018] Furthermore, the invisible orthodontic J-hook system includes a high-positioned head cap, which includes a small yellow cap and two connecting straps, and the two connecting straps are respectively connected to opposite sides of the crown of the small yellow cap; the outer end of the J-shaped hook body away from the reinforcement block is detachably connected to the connecting strap.

[0019] The present invention further provides an upper jaw invisible brace, wherein a bag-shaped structure is provided on the buccal side of the anterior teeth area of ​​the upper jaw invisible brace, wherein a receiving cavity is provided in the bag-shaped structure, wherein the receiving cavity passes through the bag-shaped structure to form a bag opening, and the bag opening faces the lower jaw anterior teeth area.

[0020] Furthermore, the maxillary invisible braces include an inner layer invisible braces and an outer layer invisible braces which are connected together by pressing and fitting, the buccal side of the outer layer invisible braces protrudes toward the buccal side to form an outer layer cavitation, the outer layer cavitation extends from the lateral incisor area to the canine area, the outer layer cavitation penetrates the side of the outer layer invisible braces facing the inner layer invisible braces and together with the inner layer invisible braces form the bag-shaped structure with the accommodating cavity; the outer layer cavitation is opened on the side facing the mandibular anterior teeth area to form a bag opening.

[0021] The present invention also provides a J hook that cooperates with the above-mentioned maxillary invisible braces, wherein the J hook comprises a J-shaped hook body and a reinforcement block, wherein the reinforcement block is fixedly connected to the inner end of the J-shaped hook body, and the reinforcement block is detachably plugged into the accommodating cavity through the bag opening.

[0022] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0023] The above-mentioned invisible braces J hook system has a maxillary invisible braces connected to the J hook through a bag-shaped structure and a reinforcement block. During correction, the extraoral traction force is transmitted to the bag-shaped structure through the J hook and the reinforcement block in turn. The bag-shaped structure is fixedly connected to the maxillary invisible braces to transmit the extraoral force, so that the correction force acts on the periodontium and maxilla, thereby achieving tooth correction and functional correction of the maxilla in early adolescence. Since the bag-shaped structure is arranged in the anterior teeth area of ​​the maxillary invisible braces, the extraoral traction force can mainly act on the periodontium and maxilla in the maxillary anterior teeth area, thereby being able to lower the maxillary anterior teeth and control their vertical growth; in conventional invisible correction, effectively lowering the upper anterior teeth and leveling deep overbite have always been the difficulties of invisible correction. The above-mentioned invisible correction J hook system can well assist conventional invisible correction, is non-invasive and improves correction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] See also Figure 1 A preferred embodiment of the present invention provides an invisible braces J hook system, comprising a maxillary invisible braces 2 and a J hook 4, wherein the maxillary invisible braces 2 is used to be worn outside the patient's maxillary dentition, and the J hook 4 is connected to the maxillary invisible braces 2 to apply extraoral traction to the maxillary invisible braces 2, thereby assisting in tooth correction.

[0042] Please also see Figure 2 , Figure 3 , Figure 8 and Fig. 9 The structure of the maxillary invisible braces 2 is substantially the same as that of the prior art, except that, in this embodiment, the maxillary invisible braces 2 are provided with a bag-shaped structure 21, a ring-shaped retention bubble 23 and a bicuspid retention bubble 25. The bag-shaped structure 21 is connected to the buccal side of the anterior tooth area of ​​the maxillary invisible braces 2. Figures 4 to 7, a receiving cavity 210 is provided in the bag-shaped structure 21, and the receiving cavity 210 passes through the bag-shaped structure 21 to form a bag opening 211, and the bag opening 211 faces the mandibular anterior teeth area, such as the direction of the lower canines. In this embodiment, the bag-shaped structure 21 is a hollow block fixedly bonded to the buccal side of the anterior teeth area of ​​the maxillary invisible braces 2, and the hollow block is a quadrangular prism structure. The receiving cavity 210 is a quadrangular prism-shaped cavity with roughly the same geometric shape as the bag-shaped structure 21. Specifically, the bag-shaped structure 21 includes two parallel and oppositely arranged bottom plates 212, an end plate 213 and two opposite inclined plates 214. The bottom plate 212 is in the shape of an isosceles trapezoid, and the end plate 213 and the inclined plate 214 are both rectangular. The end plate 213 is connected to the upper At the bottom edge, two inclined plates 214 are arranged obliquely and are respectively connected to the two oblique edges of the bottom plate 212; the bottom plate 212, the end plate 213 and the inclined plate 214 together form a receiving cavity 210, and the end of the bottom plate 212 away from the end plate 213 and the end of the inclined plate 214 away from the end plate 213 together form a bag opening 211; since the two inclined plates 214 are arranged obliquely, the cross-section of the receiving cavity 210 gradually becomes smaller in the direction away from the bag opening 211, and the bag-shaped structure 21 is a quadrangular prism structure with one end larger and the other end smaller.

[0043] One of the bottom plates 212 is fixedly bonded to the buccal side of the anterior tooth area of ​​the maxillary invisible braces 2. The "anterior tooth area" is defined according to the classification of teeth in the second edition of "Introduction to Stomatology" published by Peking University Medical Press, pages 36-38, including central incisors, lateral incisors and canines, which are shown as teeth 1-3 in the FDI marking method; the posterior tooth area includes premolars and molars, which are shown as teeth 4-8 in the FDI marking method. In this embodiment, the bottom plate 212 of the bag-shaped structure 21 extends from the maxillary lateral incisor area to the canine area. Preferably, the height of the bag-shaped structure 21 (here, the height is the vertical distance from the outer side of the end plate 213 to the bag opening 211) is about 7 mm, the bag opening 211 of the receiving cavity 210 is a rectangle of about 15*6mm-10*4㎜, the end of the receiving cavity 210 with a smaller cross-section is a rectangle of about 13*4mm-8*3㎜, and the thickness of the end plate 213, the inclined plate 214 and the bottom plate 212 are all about 1 mm, so that when the bag-shaped structure 21 is fixedly bonded to the maxillary invisible braces 2, it will not produce too much foreign body sensation. The bag-shaped structure 21 is made of resin material. Preferably, the bag-shaped structure 21 is made of the same material as the maxillary invisible braces 2, and the bag-shaped structure 21 and the maxillary invisible braces 2 are chemically fixedly bonded with the same resin material as the maxillary invisible braces 2.

[0044] The annular retention cavitation bubble 23 is convexly arranged on the buccal and lingual sides of the first molar area of ​​the maxillary invisible braces 2. The annular retention cavitation bubble 23 is in the shape of a long strip, and its length direction is parallel to the length direction of the first molar area. The annular retention cavitation bubble 23 is used in conjunction with the molar intraoral retention attachment 100. The shape of the molar intraoral retention attachment 100 matches the annular retention cavitation bubble 23. The molar intraoral retention attachment 100 is fixed to the buccal and lingual sides of the first molar 300, and is respectively embedded with the annular retention cavitation bubble 23 on the buccal and lingual sides of the first molar area of ​​the maxillary invisible braces 2. The bicuspid retention cavitation bubble 25 is convexly arranged on the lingual side of the bicuspid area of ​​the maxillary invisible braces 2. The bicuspid retention cavitation bubble 25 is in the shape of a rectangular parallelepiped, and the length direction of the bicuspid retention cavitation bubble 25 is parallel to the height direction of the bicuspids. The bicuspid retention cavitation bubble 25 is used in conjunction with the bicuspid intraoral retention attachment 200 fixed to the lingual side of the bicuspid 400. The shape of the bicuspid intraoral retention attachment 200 matches the bicuspid retention cavitation bubble 25 and is embedded with the bicuspid retention cavitation bubble 25. Both the molar intraoral retention attachment 100 and the bicuspid intraoral retention attachment 200 can be made of a light-cured nanocomposite resin (with methacrylate monomer as the main component), and the material belongs to the prior art, and will not be described here for the sake of space omission.

[0045] J Hook 4 is often used for functional correction of early adolescent malocclusion, such as: excessive vertical development of the anterior maxillary bone, deep overbite, etc. During the correction process, if the J Hook 4 can be connected to the high head cap for high elastic traction at night, it can reduce the impact of the reaction force on the adjacent teeth during the correction process and reduce the difficulty of support control. Please refer to Figure 4 In this embodiment, the J hook 4 includes a J-shaped hook body 41 and a reinforcing block 43. The reinforcing block 43 is fixedly connected to the intraoral end of the J-shaped hook body 41. The intraoral end of the J-shaped hook body 41 refers to the end of the J-shaped hook body 41 located in the oral cavity when in use. The reinforcing block 43 is detachably plugged into the receiving cavity 210 through the bag opening 211. The structure of the J hook 4 is substantially the same as the J hook structure in the prior art, except that the J hook 4 in this embodiment further includes a reinforcing block 43, which is detachably plugged into the receiving cavity 210 through the bag opening 211, thereby realizing the combination of the J hook 4 and the maxillary invisible braces 2.

[0046] In this embodiment, the reinforcing block 43 is a quadrangular prism structure plugged with the bag-shaped structure 21, and includes two parallel and opposite bottom surfaces 431, two parallel and opposite end surfaces 432, and two opposite inclined surfaces 434. The bottom surface 431 is in the shape of an isosceles trapezoid, and the end surfaces 432 and the inclined surfaces 434 are both rectangular, and one end surface 432 is connected to the lower bottom edge of the bottom surface 431, and the other end surface 432 is connected to the upper bottom edge of the bottom surface 431. The two inclined surfaces 434 are arranged obliquely and are respectively connected to the two oblique edges of the bottom surface 431. Since the two inclined surfaces 434 are arranged obliquely, the reinforcing block 43 forms a quadrangular prism structure with one end larger than the other end. In this embodiment, the inner end of the mouth of the J-shaped hook body 41 is embedded in the end of the reinforcing block 43 with a larger cross section; the inner end of the mouth of the J-shaped hook body 41 is also formed with a bending portion 411, and the bending portion 411 is embedded in the reinforcing block 43. The bending portion 411 can increase the contact area between the J-shaped hook body 41 and the reinforcing block 43, so that the connection between the J-shaped hook body 41 and the reinforcing block 43 is more secure. The end of the reinforcing block 43 with a smaller cross section is inserted into the receiving cavity 210 through the bag opening 211, and when the reinforcing block 43 is inserted into the receiving cavity 210, the two inclined surfaces 434 can respectively contact the inner walls of the two inclined plates 214 in parallel, and the end surface 432 with a smaller cross section of the reinforcing block 43 can abut against the inner wall of the end plate 213 of the bag-shaped structure 21. In this embodiment, the reinforcing block 43 includes a main body 435 and a buffer part 436 connected to each other. The main body 435 is made of hard resin, for example, thermosetting resin (polymethyl methacrylate), and is located at the end of the reinforcing block 43 with a larger cross section. The inner end of the mouth of the J-shaped hook body 41 is buried in the main body 435; the buffer part 436 is made of soft lining resin, for example, methyl acrylate soft plastic, silicone rubber, etc., and its hardness is less than that of the main body 435. The buffer part 436 is located at the end of the reinforcing block 43 with a smaller cross section. The buffer part 436 can elastically offset the inner wall of the end plate 213 with a smaller cross section in the bag-shaped structure 21. Preferably, the buffer part 436 and the main body 435 are bonded in the form of chemical bonding. The height of the buffer part 436 is about 1 / 3 of the total height of the reinforcing block 43, and the height of the main body 435 is about 2 / 3 of the total height of the reinforcing block 43. The total height of the reinforcing block 43 is the vertical distance between the two end faces 432. Preferably, the edges of the reinforcing block 43 are rounded (blunted) to achieve a smooth transition at the junction.

[0047] Please see again Figure 1The invisible correction J hook system also includes a high-positioned head cap 5. In the present embodiment, the structure of the high-positioned head cap 5 is the same as that in the prior art, including a plurality of cap straps 51, at least one intermediate strap 52 and two connecting straps 53. The intermediate strap 52 connects the plurality of cap straps 51, one end of the plurality of cap straps 51 is connected to one end of one of the connecting straps 53, and the other end of the plurality of cap straps 51 is connected to one end of another connecting strap 53. The extraoral end of the J-shaped hook body 41 away from the reinforcement block 43 (that is, the end of the J-shaped hook body 41 located outside the oral cavity when in use) is detachably connected to the connecting strap 53, which belongs to the prior art. For example, a hook is provided on the connecting strap 53, and the end of the J-shaped hook body 41 away from the reinforcement block 43 can be hooked together with the hook on the connecting strap 53 through a rubber band, or the hook on the connecting strap 53 is hooked with a spring coil, and the end of the J-shaped hook body 41 away from the reinforcement block 43 is hooked on the spring coil, thereby detachably connecting the end of the J-shaped hook body 41 away from the reinforcement block 43 to the connecting strap 53.

[0048] Please also see Fig.12 In another embodiment, the high-position head cap 5 includes a small yellow cap 6 and two connecting straps 53, and the two connecting straps 53 are respectively connected to the opposite sides of the crown 61 of the small yellow cap 6; the outer end of the J-shaped hook body 41 away from the reinforcing block 43 is detachably connected to the connecting strap 53. In this embodiment, one end of the connecting strap 53 can be connected to the brim of the crown 61 of the small yellow cap 6 by suturing, buttons, etc. It can be understood that an interlayer can be provided in the brim of the crown 61, and supporting objects such as a plastic layer can be provided in the interlayer to improve the strength of the brim of the crown 61, so as to prevent the brim of the crown 61 from being deformed too much during traction, thereby affecting the smooth progress of correction. The manner in which the J-shaped hook body 41 is detachably connected to the connecting strap 53 belongs to the prior art, and will not be described here to omit space.

[0049] As a traffic safety sign for students, the little yellow cap 6 is made of bright yellow reflective fabric. It is bright and has high resolution during the day, and it is eye-catching at night. It can remind road traffic participants to avoid traffic accidents from all angles, effectively preventing traffic accidents. Because most of the patients for early correction are primary school students aged 6-12, when patients need to wear the invisible correction J hook system during the day, the combination of the little yellow cap 6 and the J hook can help reduce the impact of the invisible correction J hook system on the patient's appearance when worn, making it more beautiful.

[0050] It can be understood that the high head cap 5 and the small yellow cap 6 can be made into different models to meet the needs of patients of different age groups.

[0051] When making the invisible correction J hook system, after obtaining the patient's current intraoral three-dimensional data, CAD / CAM and other related computer graphics technologies are used to virtually move the target tooth position. After the virtual movement is completed, the three-dimensional printing technology is used to three-dimensionally print several virtual models. After the three-dimensional printing is completed, the food and drug grade film material is heated, and a three-dimensional membrane that fits the three-dimensional model is formed by vacuum blister or pressurized blister. The three-dimensional membrane is reasonably edge-cut to ensure that the edge conforms to the wearing and mechanical principles, and the maxillary invisible braces 2 are made; the bag-shaped structure 21 is made by the resin membrane formed by hot pressing; the reinforcement block 43 is made by computer digital simulation technology, and its shape matches the geometric shape of the bag-shaped structure 21, and the reinforcement block 43 is embedded and fixed with the intraoral end of the J hook 4. Its production method belongs to the prior art, and it will not be repeated here to omit space.

[0052] When installing the above-mentioned invisible correction J hook system, the bag-shaped structure 21 is fixedly bonded to the buccal side of the canine and lateral incisor area of ​​the maxillary invisible braces 2, and the bag opening 211 of the bag-shaped structure 21 is oriented to the lower distal center (towards the lower canine); the maxillary invisible braces 2 containing the bag-shaped structure 21 is worn in the mouth, and then the reinforcing block 43 connected to the J hook 4 is installed in the receiving cavity 210 of the bag-shaped structure 21, and the outer end of the J hook 4 is connected to the connecting belt 53 of the high head cap 5 to generate correction force. The above-mentioned invisible correction J hook system is mainly worn at night, and it is recommended to be worn for about 12 hours a day. It has a low impact on daily social and learning life, and effectively maintains the advantages of invisible correction in terms of beauty and comfort.

[0053] The formation of the bag-shaped structure 21 is not limited to this embodiment. Fig.10 and Fig.11, other embodiments of the present invention provide an invisible correction J hook system, the structure of which is roughly the same as that of the invisible correction J hook system of the first embodiment, both of which include an upper invisible brace 2 and a J hook 4, the difference being the structure of the upper invisible brace 2. In this embodiment, the upper invisible brace 2 includes an inner invisible brace 26 and an outer invisible brace 27 that are connected together by pressing, the buccal side of the outer invisible brace 27 bulges toward the buccal side to form an outer cavitation 28, the outer cavitation 28 extends from the lateral incisor area to the canine area, the outer cavitation 28 penetrates the side of the outer invisible brace 27 facing the inner invisible brace 26 and together with the inner invisible brace 26, forms the bag-shaped structure 21 with the receiving cavity 210. The outer cavitation 28 is opened on the side facing the mandibular anterior teeth area to form a bag opening 211. During manufacturing, the bag opening 211 can be obtained by punching a hole on the side of the outer cavitation 28 facing the mandibular anterior teeth area. The buccal and lingual sides of the first molar area of ​​the outer invisible braces 27 and the inner invisible braces 26 are both convexly provided with annular retention cavities 23, and the annular retention cavities 23 of the inner invisible braces 26 are embedded in the annular retention cavities 23 of the outer invisible braces 27; the lingual sides of the bicuspid area of ​​the outer invisible braces 27 and the inner invisible braces 26 are both convexly provided with bicuspid retention cavities 25, and the bicuspid retention cavities 25 of the inner invisible braces 26 are embedded in the bicuspid retention cavities 25 of the outer invisible braces 27. It can not only achieve the complete covering effect of the teeth through the inner invisible braces 26, but also form a bag-shaped structure 21 that can be connected to the J hook 4 between the inner invisible braces 26 and the outer invisible braces 27. The bag-shaped structure 21 is formed by pressing the inner invisible braces 26 and the outer invisible braces 27 together. It is easier to manufacture and does not require chemical bonding or hot melting for connection. It has lower cost and will not produce toxic substances that are unfriendly to the human body after the material is hot-melted.

[0054] In the above-mentioned invisible correction J hook system, the maxillary invisible braces 2 are connected to the J hook 4 through the bag-shaped structure 21 and the reinforcement block 43. During correction, the extraoral traction force is transmitted to the bag-shaped structure 21 through the J hook 4 and the reinforcement block 43 in sequence. The bag-shaped structure 21 is fixedly connected to the maxillary invisible braces 2 to transmit the extraoral traction force, so that the correction force acts on the periodontium and the maxilla, thereby achieving the correction of teeth and the functional correction of the early jaw of adolescents. Since the bag-shaped structure 21 is arranged in the anterior teeth area of ​​the maxillary invisible braces 2, the extraoral traction force can mainly act on the periodontium and the maxilla in the maxillary anterior teeth area, and then the maxillary anterior teeth can be depressed and controlled to grow vertically. In addition, in this embodiment, the bag-shaped structure 21 is extended from the maxillary lateral incisor area to the canine area, which can greatly increase the force application area of ​​the extraoral traction force on the maxillary invisible braces 2, which is conducive to improving the efficiency and effect of correction.

[0055] In the above-mentioned invisible correction J hook system, the bag-shaped structure 21 is connected to the maxillary invisible braces 2 by fixed bonding. There is no need to drill holes or cut off the maxillary invisible braces 2, which will not destroy the integrity and covering effect of the maxillary invisible braces 2. The complete maxillary invisible braces 2 can be used to apply force to the entire row of teeth as a whole to achieve correction of the entire dentition, and avoid being set on a single tooth, causing unnecessary movement of the single tooth. The extraoral traction force acts on the maxillary anterior teeth area through the combined structure of the reinforcement block 43 and the bag-shaped structure 21, reducing the impact of the reaction force on the adjacent teeth during correction and reducing the difficulty of support control. In conventional invisible correction, effectively lowering the upper anterior teeth and leveling deep overbite have always been the difficulties of invisible correction. The above-mentioned invisible correction J hook system can well assist conventional invisible correction, is non-invasive and improves correction efficiency.

[0056] In the above-mentioned invisible correction J hook system, the J hook 4 is combined with the maxillary invisible braces 2 through the reinforcement block 43 and the bag-shaped structure 21. Compared with the traction protrusion of the prior art, the reinforcement block 43 and the bag-shaped structure 21 are not easy to deform or tilt under the action of external force, and the force-bearing surface with the maxillary invisible braces 2 is larger, so that the extraoral traction force can be more evenly transmitted to the maxillary invisible braces 2. Therefore, it is not necessary to thicken the force-bearing part of the maxillary invisible braces 2, reducing the adverse effects on the teeth caused by the uneven thickness of the maxillary invisible braces 2 during the correction process, and ensuring that the maxillary invisible braces 2 are comfortable to wear. At the same time, the way of plugging the reinforcement block 43 and the bag-shaped structure 21 can make it easier to disassemble and assemble the J hook 4.

[0057] In the above-mentioned invisible orthodontic J-hook system, the reinforcing block 43 is inserted into the bag-shaped structure 21 after passing through the bag opening 211. Due to the orientation design of the bag opening 211 and the limiting effect of the accommodating cavity 210, the reinforcing block 43 will not fall out of the bag-shaped structure 21 under the action of extraoral traction. Under the premise of ensuring safety, the doctor can apply a larger external force to the bracketless invisible orthodontic appliance according to the patient's condition.

[0058] The above-mentioned invisible correction J hook system can also limit the angle position of the reinforcement block 43 connected to the J hook 4 through the receiving cavity 210. Compared with the method of connecting the J hook 4 through traction protrusions, pull rings and incisions in the prior art, it can more accurately control the direction of the extraoral traction force. When the bag-shaped structure 21 is fixed, the doctor can set the installation angle of the bag-shaped structure 21 according to the specific situation of each patient, which is more convenient to formulate a personalized correction plan for the patient. For example, the angle of the bag mouth 211 can be adjusted to face the mandibular central incisor area. At this time, the force direction is backward and upward, which is conducive to lowering the maxillary anterior teeth and adducting them at the same time, which is conducive to improving the protrusion of the anterior teeth.

[0059] The above-mentioned invisible correction J hook system, its bag-shaped structure 21 is a hollow quadrangular prism structure, and has an inclined plate 214 that is arranged obliquely, and the reinforcement block 43 has an inclined surface 434 that is in parallel contact with the inner wall of the inclined plate 214 of the bag-shaped structure 21. During correction, not only can the extraoral force be transmitted through the contact between the end surface 432 of the reinforcement block 43 and the end plate 213 of the bag-shaped structure 21, but the contact area between the reinforcement block 43 and the bag-shaped structure 21 can also be further increased through the cooperation between the inclined surface 434 and the inclined plate 214, so that the extraoral traction force can be more evenly transmitted to the maxillary invisible braces 2, thereby preventing the maxillary invisible braces 2 from being deformed.

[0060] The above-mentioned invisible orthodontic J-hook system, its reinforcement block 43 includes a main body 435 and a buffer part 436 which are interconnected. The main body 435 is made of hard resin, which can better support the J hook 4. The buffer part 436 is made of soft lining resin. The soft lining resin has a certain elasticity and a certain buffering effect. It can apply a more moderate and uniform external force to the bag-shaped structure 21 and the invisible braces 2 through the soft lining resin, thereby further reducing the deformation of the maxillary invisible braces 2.

[0061] The above-mentioned invisible correction J hook system has a bicuspid retention cavitation bubble 25 on the lingual side of the bicuspid area of ​​the maxillary invisible brace 2, which can cooperate with the bicuspid intraoral retention attachment 200 fixed on the lingual side of the bicuspid 400 when in use, and a ring-shaped retention cavitation bubble 23 is provided on the buccal and lingual sides of the first molar area, which can cooperate with the molar intraoral retention attachment 100 fixed on the first molar 300 when in use, so that the maxillary invisible brace 2 can be fixed on the maxillary teeth. The first molar area adopts a ring-shaped retention cavitation bubble 23, which can simulate the traditional orthodontic band ring to enhance the retention of the maxillary first molar 100, thereby reducing the probability of the maxillary invisible brace 2 coming off during traction. The bicuspid area is only provided with a bicuspid retention cavitation bubble 25 on its lingual side, which increases the retention of the maxillary bicuspid 400 while reducing the interference of the reinforcement block 43 when it is worn into the bag-shaped structure 21, so as to facilitate the wearing of the invisible correction J hook system.

[0062] The embodiment of the present invention further provides a maxillary invisible brace 2 used in the above-mentioned invisible correction J hook system, wherein a bag-shaped structure 21 is provided on the buccal side of the anterior teeth area of ​​the maxillary invisible brace 2, and a receiving cavity 210 is provided in the bag-shaped structure 21, and the receiving cavity 210 passes through the bag-shaped structure 21 to form a bag opening 211, and the bag opening 211 faces the mandibular anterior teeth area. The embodiment of the present invention further provides a J hook 4 that cooperates with the above-mentioned maxillary invisible brace 2, and the J hook 4 includes a J-shaped hook body 41 and a reinforcement block 43, and the reinforcement block 43 is fixedly connected to the inner end of the J-shaped hook body 41, and the reinforcement block 43 is detachably plugged into the receiving cavity 210 through the bag opening 211.

[0063] It is understood that the shapes of the bag-shaped structure 21, the receiving cavity 210, and the reinforcing block 43 are not limited to the present embodiment. For example, in other embodiments, the bag-shaped structure 21 may also be in a cubic shape, and the receiving cavity 210 and the reinforcing block 43 may be in a quadrangular prism shape as in the present embodiment. The sizes of the bag-shaped structure 21 and the reinforcing block 43 may be set to other values ​​as needed.

[0064] It can be understood that the receiving cavity 210 is not limited to the quadrangular prism-shaped cavity in the present embodiment. For example, in other embodiments, the hole wall surrounding the receiving cavity 210 may have one or more first inclined portions so that the cross-sectional area of ​​the receiving cavity 210 gradually decreases in the direction away from the bag opening 211; the reinforcing block 43 is correspondingly provided with one or more second inclined portions, and the second inclined portions can be in parallel contact with the first inclined portions.

[0065] It can be understood that the bottom plate 212 of the bag-shaped structure 21 may also cover only the canine area of ​​the maxillary teeth, or may also cover only the lateral incisor area.

[0066] It can be understood that the connection method between the J-shaped hook body 41 and the reinforcement block 43 is not limited to the present embodiment. For example, they may also be connected by threaded connection.

[0067] Other unexplained parts of the present invention are the same as those of the prior art.
