Description

Technical Field

[0001] This application belongs to the field of orthodontic appliance technology, specifically relating to an orthodontic appliance and orthodontic components. Background Technology

[0002] The mixed dentition period (approximately 6-12 years old) is a crucial stage for the shedding of primary teeth and the eruption of permanent teeth. During this period, due to premature loss of primary teeth, the reserved space in the dental arch is easily encroached upon by adjacent teeth, resulting in loss or insufficiency. This loss or insufficiency of space is a common problem during the mixed dentition period, directly hindering the normal eruption of the successor permanent teeth, leading to malocclusion, impaction, and other malocclusions. Currently, push springs are commonly used to address this space loss problem. However, these push springs require frequent chairside checkups, and their spiral structure easily entangles and accumulates food debris and plaque, making them difficult to clean. Summary of the Invention

[0029] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0030] Please refer to Figure 1 This application provides an orthodontic component 100 for orthodontic treatment, the function of which includes, but is not limited to, creating gaps.

[0031] The orthodontic assembly 100 includes an elastic cord 2, a lingual buckle 3, and an orthodontic appliance 1 as described in any of the following embodiments. The lingual buckle 3 is used to be installed on the teeth, and the elastic cord 2 is used to connect the lingual buckle 3 and the hook 12 on the orthodontic appliance 1.

[0032] The lingual clip 3 can be fixed to the tooth by adhesive bonding. The tooth to which the lingual clip 3 is fixed will be referred to as the spacer tooth 200 in the following description. The material of the lingual clip 3 can be, but is not limited to, hard materials such as metal or plastic.

[0033] The elastic cord 2 is soft and elastic, and its material can be, but is not limited to, medical-grade latex, polymer, etc. The elastic cord 2 can be an elastic cord with two free ends, or it can be a loop-shaped cord (such as a rubber band).

[0034] The following describes in detail, with reference to the accompanying drawings, the orthodontic appliance 1 in the orthodontic assembly 100 described above.

[0035] Please refer to Figure 1 and Figure 2 This application also provides an orthodontic appliance 1, which includes: an arch-shaped body 11 and a hook-on body 12.

[0036] The arch-shaped body 11 has an alveolar ridge X1 and a notch X2, the alveolar ridge X1 being used to accommodate teeth. The arch-shaped body 11 includes an occlusal pad 111 and an outer baffle 112, the outer baffle 112 being connected to the outside of the occlusal pad 111. The occlusal pad 111 forms the bottom wall of the alveolar ridge X1, and the outer baffle 112 forms the side wall of the alveolar ridge X1. The outer baffle 112 has the notch X2, which communicates with the alveolar ridge X1.

[0037] The hook body 12 protrudes from the outer baffle 112 on the side opposite to the alveolar bone X1. The hook body 12 includes a first hook body 12a and a second hook body 12b, which are disposed on both sides of the notch X2 along the extension direction of the arch-shaped body 11. The first hook body 12a and the second hook body 12b are used to cooperate with the elastic cord 2 and the lingual buckle 3 to pull two adjacent teeth respectively.

[0038] Specifically, the occlusal pad 111 has an arched shape, and the outer baffle 112 is connected to the outside of the occlusal pad 111 along its direction, thus making the overall arched body 11 present an arch-shaped structure that matches the patient's dental arch shape. The outer baffle 112 has a notch X2 for avoiding the occupying tooth 200. The edge of the notch X2 can be straight or curved. The end of the outer baffle 112 away from the occlusal pad 111 can be penetrated by the notch X2 (e.g., ...). Figure 2As shown in the diagram, the tooth may not be fully penetrated; this application only illustrates penetration. It is understood that penetration facilitates the full exposure of the occupant tooth 200 through the notch X2. An attachment 12 is provided on the outer side of the outer baffle 112. This attachment 12 is a convex structure on the orthodontic appliance 1. The protruding attachment 12 facilitates the connection of the elastic cord 2, serving as a point of force application for traction of the occupant tooth 200. Attachments 12 are provided on both sides of the notch X2, namely a first attachment 12a and a second attachment 12b. The first attachment 12a is located on the left side of the notch X2, and the second attachment 12b is located on the right side of the notch X2.

[0039] When the patient wears appliance 1, their teeth are located within the alveolar bone X1, the occlusal pad 111 is positioned between the maxillary and mandibular teeth, the outer baffle 112 is located on the outer side of the teeth, the first connector 12a and the second connector 12b abut against the inner side of the oral cavity, and the occlusal tooth 200 is exposed through the notch X2 in the outer baffle 112. The occlusal pad 111, also known as an occlusal plate, is used for the user to bite, thereby exercising the masseter muscle and correcting the bite.

[0040] Example Description: When a patient requires space creation treatment, firstly, two lingual clips 3 (defined as the first lingual clip 31 and the second lingual clip 32, respectively) are fixed to two adjacent occluded teeth 200. Then, the orthodontic appliance 1 is placed in the oral cavity. Finally, an elastic cord 2 (defined as the first elastic cord 21) is connected to the first lingual clip 31 and the first hook 12a, and another elastic cord 2 (defined as the second elastic cord 22) is connected to the second lingual clip 32 and the second hook 12b. After the elastic cords 2 are connected, they will be in a stretched state. The stretched elastic cord 2 has an elastic recoil force, which will provide a continuous and gentle tension on the occluded teeth 200. Since the first hook 12a and the second hook 12b are located on both sides of the gap X2, the tension of the first elastic cord 21 and the second elastic cord 22 on the two adjacent occluded teeth 200 is opposite or approximately opposite. Understandably, during the continuous treatment, the two adjacent spacer teeth 200 will gradually be pulled apart, and the gap between them will continue to widen, eventually forming a pre-set space (the above process is the process of opening the gap), so as to provide a basis for the subsequent target tooth 300 to enter the space.

[0041] In summary, the orthodontic appliance 1 provided in this application has a notch X2 on the outer baffle 112, and a first hook 12a and a second hook 12b are respectively provided on both sides of the notch X2. The first hook and the second hook can work with the elastic cord 2 and the lingual buckle 3 to form opposite or approximately opposite pulling forces on two adjacent teeth, so that the two teeth are gradually pulled apart, thereby realizing the process of creating gaps. In addition, the hook 12 that realizes the gap creation is a convex structure on the orthodontic appliance 1, which is simpler and easier to clean than the use of push springs in the prior art.

[0042] Please refer to Figure 2 In one embodiment, the alveolar bone X1 includes a maxillary alveolar bone X11, which is used to accommodate maxillary teeth. The outer baffle 112 includes an upper outer baffle 1121, which is bent and connected to the occlusal pad 111. The upper outer baffle 1121 forms the sidewall of the maxillary alveolar bone X11, and the upper outer baffle 1121 is provided with the notch X2, which communicates with the maxillary alveolar bone X11. The notch X2 of the upper outer baffle 1121 is provided with the first hook 12a and the second hook 12b.

[0043] for Figure 2 The structure shown is suitable for situations where space needs to be created between the maxillary teeth, i.e., the spacer tooth 200 is a maxillary tooth. Specifically, when the patient wears appliance 1, their maxillary teeth are located within the upper alveolar bone X11, and the upper outer guard 1121 is positioned outside the maxillary teeth. Two adjacent spacer teeth 200 in the maxillary teeth are exposed through the notch X2. The first connector 12a and the second connector 12b are used in conjunction with the elastic cord 2 and the lingual buckle 3 to pull these two spacer teeth 200, thereby continuously widening the space between the two spacer teeth 200 and creating the space. It should be noted that, in the arched extension direction of the upper outer guard 1121, the notch X2 can be located at any position on the upper outer guard 1121, as long as the first connector 12a and the second connector 12b can be placed on both sides of the notch X2. Figure 3 The location of the notch X2 shown is merely an example. The specific location of the notch X2 depends on the requirements and is not limited here. For example, the notch X2 located on the upper outer section 1121 just exposes two upper canines, so that these two exposed upper canines serve as placeholder teeth 200.

[0044] Please refer to Figure 3In one embodiment, the alveolar bone X1 includes a lower alveolar bone X12, which is used to accommodate mandibular teeth. The outer baffle 112 includes a lower outer baffle 1122, which is bent and connected to the occlusal pad 111. The lower outer baffle 1122 forms the sidewall of the lower alveolar bone X12, and the lower outer baffle 1122 is provided with the notch X2, which communicates with the lower alveolar bone X12. The notch X2 of the lower outer baffle 1122 is provided with the first hook 12a and the second hook 12b.

[0045] for Figure 3 The structure shown is suitable for situations where space needs to be created between the mandibular teeth, i.e., the spacer teeth 200 are mandibular teeth. Specifically, when the patient wears appliance 1, their mandibular teeth are located within the lower alveolar bone X12, and the lower outer guard 1122 is located outside the mandibular teeth. Two adjacent spacer teeth 200 in the mandibular teeth are exposed through the notch X2. The first connector 12a and the second connector 12b are used in conjunction with the elastic cord 2 and the lingual buckle 3 to pull these two spacer teeth 200, so that the space between the two spacer teeth 200 is continuously widened, thereby creating space. It should be noted that, in the arched extension direction of the lower outer guard 1122, the notch X2 can be located at any position on the lower outer guard 1122, as long as the first connector 12a and the second connector 12b can be set on both sides of the notch X2. Figure 3 The location of the notch X2 shown is merely an illustrative example. The specific location of the notch X2 depends on the requirements and is not limited here. For example, the notch X2 located on the lower outer section 1122 just exposes two lower canines, so that these two exposed lower canines serve as placeholder teeth 200.

[0046] Please refer to Figure 4 In one embodiment, the alveolar bone X1 includes a maxillary alveolar bone X11, which is used to accommodate maxillary teeth. The outer baffle 112 includes an upper outer baffle 1121, which is bent and connected to the occlusal pad 111. The upper outer baffle 1121 forms the sidewall of the maxillary alveolar bone X11, and the upper outer baffle 1121 is provided with the notch X2, which communicates with the maxillary alveolar bone X11. The notch X2 of the upper outer baffle 1121 is provided with the first hook 12a and the second hook 12b. Furthermore, the alveolar bone X1 includes a lower alveolar bone X12, which is used to accommodate mandibular teeth. The outer baffle 112 includes a lower outer baffle 1122, which is bent and connected to the occlusal pad 111. The lower outer baffle 1122 forms the sidewall of the lower alveolar bone X12, and the lower outer baffle 1122 is provided with the notch X2, which communicates with the lower alveolar bone X12. The notch X2 of the lower outer baffle 1122 is provided with the first hook body 12a and the second hook body 12b.

[0047] for Figure 4 The structure shown is suitable for situations where both mandibular and mandibular teeth require space creation, i.e., both maxillary and mandibular teeth have spacer teeth 200. The first and second connectors 12a and 12b on the upper outer stop 1121 are used in conjunction with the elastic cord 2 and lingual clip 3 to pull the two spacer teeth 200 in the maxilla to create space. The first and second connectors 12a and 12b on the lower outer stop 1122 are used in conjunction with the elastic cord 2 and lingual clip 3 to pull the two spacer teeth 200 in the mandible to create space. It should be noted that when using… Figure 4 During the opening of the gaps in the orthodontic appliance 1 shown, the gaps can be opened simultaneously for both the maxillary and mandibular teeth, or the gaps can be opened for the maxillary teeth first, followed by the mandibular teeth, or vice versa. It should be noted that, in the arched extension direction of the upper outer stop 1121, the notch X2 can be located at any position on the upper outer stop 1121, as long as the first hook body 12a and the second hook body 12b can be installed on both sides of the notch X2; similarly, in the arched extension direction of the lower outer stop 1122, the notch X2 can be located at any position on the lower outer stop 1122, as long as the first hook body 12a and the second hook body 12b can be installed on both sides of the notch X2. The specific location of the notch X2 depends on the requirements and is not limited here. For example, the notch X2 in the upper outer section 1121 just exposes two upper canines, so that these two exposed upper canines serve as placeholder teeth 200; and for another example, the notch X2 in the lower outer section 1122 just exposes two lower canines, so that these two exposed lower canines serve as placeholder teeth 200.

[0048] Please refer to Figure 5 In one embodiment, each of the hooks 12 includes a columnar portion 121 and a limiting portion 122. The columnar portion 121 is connected to the outer baffle 112, and the limiting portion 122 is connected to the end of the columnar portion 121 away from the outer baffle 112. The rotation diameter of the limiting portion 122 is larger than the rotation diameter of the columnar portion 121.

[0049] Specifically, the so-called rotation diameter refers to the largest circle diameter projected by the trajectory of an object rotating around its own axis. This does not imply that the columnar portion 121 and the limiting portion 122 will rotate, but rather emphasizes that the limiting portion 122 is thinner than the columnar portion 121. The rotation diameter of the limiting portion 122 is larger than that of the columnar portion 121. With this arrangement, when the elastic rope 2 is fitted onto the columnar portion 121, the limiting portion 122 will limit the elastic rope 2, thereby preventing it from slipping off the hook body 12. The cross-sectional shape of the columnar portion 121 can be approximately circular, rectangular, triangular, elliptical, etc., and similarly, the cross-sectional shape of the limiting portion 122 can also be approximately circular, rectangular, triangular, elliptical, etc.

[0050] Please refer to Figure 5 In one embodiment, the limiting portion 122 has an outer surface 1221 facing away from the columnar portion 121, and the outer surface 1221 is either flat or curved. Specifically, the outer surface 1221 is the outer surface of the limiting portion 122 on the side away from the arch-shaped body 11. When the patient wears the orthodontic appliance 1, since the outer surface 1221 of the limiting portion 122 will abut against the inside of the patient's mouth, if there are sharp protrusions on the outer surface 1221, it will cause discomfort to the patient. In this embodiment, the outer surface 1221 is set as a flat or curved surface, thereby making the patient more comfortable. The curved surface can be a sphere, a parabola, an ellipsoid, etc.

[0051] Please refer to Figures 2 to 5 In one embodiment, the projection shape of the limiting part 122 onto the outer baffle 112 is circular. That is, the outline of the limiting part 122 in the circumferential direction is circular. This arrangement can avoid sharp corners in the circumferential direction, making the patient more comfortable.

[0052] In one embodiment, the limiting portion 122 of the connector 12 is elastically deformable. This design allows the limiting portion 122 to undergo appropriate elastic compression when it abuts against the inside of the patient's mouth, thereby reducing the feeling of contact and improving comfort. The limiting portion 122 can be, but is not limited to, made of elastic materials such as thermoplastic elastomer (TPE), thermoplastic polyurethane elastomer (TPU), or silicone rubber.

[0053] In one embodiment, the limiting part 122 of the hook body 12 is a rigid component. This configuration provides a better limiting effect on the elastic rope 2, ensuring a continuous and stable traction force. The rigid component can be made of, but is not limited to, rigid plastics, metals, or other rigid materials.

[0054] In one embodiment, the columnar portion 121 of the connector 12 is elastically deformable. This design allows the columnar portion 121 to undergo appropriate elastic compression or bending when the limiting portion 122 abuts against the inside of the patient's mouth, thereby reducing the feeling of contact and improving comfort. The columnar portion 121 can be, but is not limited to, made of elastic materials such as thermoplastic elastomer (TPE), thermoplastic polyurethane elastomer (TPU), or silicone rubber.

[0055] In one embodiment, the columnar portion 121 of the connector 12 is a rigid component, which can be, but is not limited to, rigid materials such as rigid plastics or metals. It is understood that by providing a rigid component, bending of the columnar portion 121 can be prevented during tooth traction, thereby maintaining a stable traction force.

[0056] Please refer to Figure 6 In one embodiment, the columnar portion 121 of the connector 12 includes a rigid core 1211 and a soft sleeve 1212. The opposite ends of the rigid core 1211 are connected to an outer baffle 112 and a limiting portion 122, respectively. The soft sleeve 1212 wraps around the outer periphery of the rigid core 1211. The rigid core 1211 is made of a rigid material (such as the aforementioned rigid plastic or metal), and the soft sleeve 1212 is made of a soft material (such as the aforementioned TPE, TPU, or silicone rubber). It is understood that the rigid core 1211 prevents the columnar portion 121 from bending during tooth traction. The soft sleeve 1212 protects the rigid core 1211 (e.g., preventing corrosion) and also prevents the rigid core 1211 from irritating the oral cavity.

[0057] Please refer to Figure 7 In one embodiment, the columnar portion 121 is provided with an annular groove X3 around its circumference, which is used to accommodate the elastic rope 2. It is understood that when the elastic rope 2 is in the annular groove X3, it can prevent the elastic rope 2 from sliding arbitrarily along the axial direction of the columnar portion 121, so that the elastic rope 2 can provide a continuous and stable traction force, and can also avoid the elastic rope 2 from suddenly breaking after repeated sliding wear.

[0058] Please refer to Figure 2 and Figure 3 In one embodiment, the bow-shaped body 11 further includes an inner baffle 113, which is bent and connected to the inner side of the occlusal pad 111. The inner baffle 113, the outer baffle 112, and the occlusal pad 111 together form the alveolar bone X1.

[0059] Specifically, the outer baffle 112 and the inner baffle 113 are arranged opposite each other and are located on opposite sides of the occlusal pad 111. The outer baffle 112 and the inner baffle 113 respectively form the two sidewalls of the alveolar bone X1, and the occlusal pad 111 forms the bottom wall of the tooth. When the patient wears the orthodontic appliance 1, their teeth are located within the alveolar bone X1, that is, the teeth will be between the outer baffle 112 and the inner baffle 113. In the case of misaligned teeth, the outer baffle 112 or the inner baffle 113 will also act on the teeth. During continuous wear, the outer baffle 112 or the inner baffle 113 can guide the teeth to the correct position, so that the teeth are aligned.

[0060] The outer baffle 112 and the occlusal pad 111 are bent and connected to form a certain angle. This angle can be determined according to the patient's ideal dental arch shape, and can be, but is not limited to, 89°, 90°, 92°, 95°, 100°, 105°, 108°, etc. Similarly, the inner baffle 113 and the occlusal pad 111 are bent and connected to form a certain angle. This angle can be determined according to the patient's ideal dental arch shape, and can be, but is not limited to, 89°, 90°, 92°, 95°, 100°, 105°, 108°, etc. Optionally, the angle formed by the outer baffle 112 and the occlusal pad 111 is greater than 90°, and the angle formed by the inner baffle 113 and the occlusal pad 111 is greater than 90°. This arrangement facilitates the entry of the user's teeth into the alveolar bone X1.

[0061] Please refer to Figure 2 and Figure 3 In one embodiment, the alveolar bone X1 includes an upper alveolar bone X11, an outer baffle 112 includes an upper outer baffle 1121, and an inner baffle 113 includes an upper inner baffle 1131. The upper outer baffle 1121, the upper inner baffle 1131, and the occlusal plate together enclose the upper alveolar bone X11. The alveolar bone X1 also includes a lower alveolar bone X12, an outer baffle 112 includes a lower outer baffle 1122, and an inner baffle 113 includes a lower inner baffle 1132. The lower outer baffle 1122, the lower inner baffle 1132, and the occlusal plate together enclose the lower alveolar bone X12. The upper alveolar bone X11 and the lower alveolar bone X12 are located on opposite sides of the occlusal pad 111. When the user wears the orthodontic appliance 1, the maxillary teeth are located within the upper alveolar bone X11, and the mandibular teeth are located within the lower alveolar bone X12. Using this structural form of the orthodontic appliance 1, the maxillary and mandibular teeth can be aligned, establishing a correct occlusal relationship.

[0062] Please refer to Figure 2In one embodiment, the upper inner baffle 1131 and the lower inner baffle 1132 of the inner baffle 113 further enclose a tongue-accommodating space X4 that is opposite to the occlusal plate. This tongue-accommodating space X4 is used to accommodate the tongue, meaning that during use, the patient's tongue will be within the tongue-accommodating space X4. The inner baffle 113 can effectively prevent the tongue from interfering with the orthodontic appliance 1, ensuring the orthodontic effect. Furthermore, during wear, the inner baffle 113 can also adjust the tongue position, establish nasal breathing, and correct the bad habit of mouth breathing.

[0063] In one embodiment, the hook 12 is non-detachably connected to the outer baffle 112. "Non-detachable" means that the hook 12 cannot be separated from the outer baffle 112 without damaging the structure. This non-detachability can be achieved, but is not limited to, bonding or integral manufacturing. It is understood that the non-detachable connection between the hook 12 and the outer baffle 112 prevents the elastic cord 2 from pulling the hook 12 off the outer baffle 112 during tooth traction, thus ensuring continuous stability during the traction process.

[0064] In one embodiment, the mounting body 12 is detachably connected to the outer baffle 112. Detachable means that the mounting body 12 can be separated from the outer baffle 112 without damaging the structure. That is, the mounting body 12 is made as an accessory, allowing for different specifications to be selected according to needs. For example, some patients may not want the mounting body 12 to be too long, in which case a shorter size can be selected. The detachable connection can be achieved, but is not limited to, threaded connections, magnetic connections, and snap-fit ​​connections. A threaded connection means that the mounting body 12 has external threads, and the outer baffle 112 has threaded holes; the mounting body 12 is screwed into the threaded holes, thus achieving a detachable connection. A magnetic connection means that either the mounting body 12 or the outer baffle 112 has a magnet, and the other has a magnetic object that can be attracted by the magnet; the two are magnetically attracted together by the magnet and the magnetic object, thus achieving a detachable connection. The snap-fit ​​connection refers to the fact that the hanger 12 is provided with a snap-fit ​​head that can be elastically deformed, and the outer baffle 112 is provided with a snap-fit ​​interface. The snap-fit ​​head of the hanger 12 enters into the snap-fit ​​interface through elastic deformation and forms a snap-fit ​​effect, thereby realizing a detachable connection.

[0065] In one embodiment, the bow-shaped body 11 is elastically deformable. This type of elastically deformable orthodontic appliance 1 can also be called a silicone orthodontic appliance, which is more suitable for children in their growth and development stage. It should be noted that the "silicone" in silicone orthodontic appliances does not imply that its core material is silicone, but only indicates that it is soft and elastic to the touch. The material of the bow-shaped body 11 can be, but is not limited to, thermoplastic elastomer (TPE), thermoplastic polyurethane elastomer (TPU), silicone rubber, and other elastic materials. It should be noted that the material of the hook body 12 can be the same as or different from the material of the bow-shaped body 11.

[0066] The technical means disclosed in this application are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
