Description

Technical Field

[0001] This utility model relates to the field of orthodontic appliances, and in particular to an orthodontic appliance. Background Technology

[0002] In the field of pediatric orthodontics, orthodontic treatment and dentition management during the mixed dentition period face multiple technical challenges. Existing orthodontic appliances struggle to address core needs such as intervention for poor oral habits, protection of primary tooth stability, and space maintenance. Specifically: 1. Interference of poor oral habits with orthodontic outcomes: Children often exhibit bad habits such as tongue thrusting, tongue extension, teeth licking, and thumb sucking during orthodontic treatment. Primary and persistent tongue thrusting exert abnormal tongue muscle forces on the upper and lower anterior teeth, leading to retrusion of the upper anterior teeth and excessive protrusion of the lower anterior teeth. This counteracts the traction force of the orthodontic appliance, delaying or even reversing the process of correcting malocclusion. However, existing orthodontic appliances primarily focus on the mechanical adjustment of teeth or jawbones, lacking structures to restrict abnormal tongue movements, thus failing to prevent the destructive effects of bad habits at their source. 2. Limitations in force application due to poor stability of primary teeth: Due to physiological root resorption, primary teeth... Figure 1 In the orthodontic appliance, point A is inherently less stable. If used as a fixed fulcrum to apply force to permanent teeth or the jawbone, it can easily accelerate the loosening and loss of deciduous teeth due to concentrated local force. 3. Loss of space during the mixed dentition period and disordered eruption of permanent teeth: There is a significant time difference in the eruption of permanent teeth in children. When deciduous teeth fall out prematurely before the corresponding permanent teeth have erupted, such as... Figure 1 In case B, the already erupted permanent teeth in the oral cavity will tilt and shift into the gap due to the loss of normal spatial constraint, thus encroaching on the eruption path of the unerupted permanent teeth, such as... Figure 1 C in the middle can lead to crowded teeth, impacted permanent teeth, or abnormal eruption direction.

[0003] Current orthodontic appliances often only solve a single problem, such as having only a tongue-blocking function or only acting as a space maintainer. For example, the mandibular tongue-blocking structure disclosed in Chinese Patent Publication No. CN223169820U cannot change the eruption direction of permanent teeth while ensuring the stability of deciduous teeth.

[0004] Therefore, it is essential to provide a dental appliance that addresses the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide a dental appliance that overcomes the shortcomings of existing technologies. This dental appliance forms multiple tension fixation points, which stably apply orthodontic force while reducing the impact on other teeth, lowering the risk of loosening and falling out of deciduous teeth, and also preventing the bad habit of protruding the tongue.

[0006] The above-mentioned objectives of this utility model are achieved through the following technical measures: A dental appliance is provided, comprising multiple loops for fitting onto deciduous or permanent teeth as fixation points, a connecting device, a traction hook for pulling the permanent tooth to be corrected, a lingual rail for creating an area of ​​contact with the tongue to prevent the tongue from protruding forward, and a fixation hook for fixing the permanent tooth to be corrected.

[0023] exist Figures 2 to 4 This includes: 100 ring, 200 traction hook, 300 connecting device, 400 fixing hook, 500 tongue rail, 600 connecting rod, 700 tongue, 800 permanent tooth to be corrected, 900 connector. Detailed Implementation

[0024] The technical solution of this utility model will be further explained with reference to the following embodiments.

[0025] Example 1 A type of orthodontic appliance, such as Figure 2As shown, the device includes multiple loops 100 for fitting onto deciduous or permanent teeth as fixing points, a connecting device 300, a traction hook 200 for pulling the permanent tooth 800 to be corrected, a lingual rail 500 for forming an abutment area with the tongue 700 to prevent the tongue 700 from protruding forward, and a fixing hook 400 for fixing to the permanent tooth 800 to be corrected. The loops 100 are fixedly connected to the connecting device 300, the traction hook 200 is fixedly connected to at least one loop 100, the lingual rail 500 is fixedly assembled to the connecting device 300 and located on the lingual side of the incisor, and the fixing hook 400 is fastened to the traction hook 200 via a connector 900. The connector 900 in this invention is a rubber band.

[0026] The band 100 is divided into a first band 100 fitted to the left jaw tooth and a second band 100 fitted to the right jaw tooth, depending on the position of the jaw tooth. Both the first and second bands 100 are fixedly connected to the connecting device 300. This invention also includes two pairs of connecting rods 600. One pair of connecting rods 600 connects all the first bands 100 into a single closed structure, and the other pair of connecting rods 600 connects all the second bands 100 into another single closed structure. At least two first bands 100 and at least two second bands 100 are provided. This embodiment is illustrated by the example of having two first bands 100 and two second bands 100.

[0027] It should be noted that all the first bands 100 and all the second bands 100 of this utility model constitute an integral structure. This enhances the stability and force consistency of the unilateral fixation point, specifically in the following ways: 1. Increased unilateral support strength: After the bands 100 on the same side are connected as a whole by the connecting rod 600, the orthodontic force borne by a single band 100 can be distributed to multiple teeth, preventing single teeth, especially deciduous teeth, from loosening or falling out due to excessive local force. It also enhances the load-bearing capacity of the unilateral fixation point. 2. Guaranteed unilateral force synchronization: The integral structure ensures that multiple teeth on the same side are subjected to force in a coordinated manner, avoiding force deviations caused by displacement or loosening of a single band 100, thereby stably transmitting the orthodontic force and improving the control accuracy of the eruption direction of permanent teeth. 3. Strengthen the connection between the left and right sides: When the overall structure of the left and right sides is connected by the connecting device 300, a more stable cross-jaw support frame can be formed, providing a reliable force source fulcrum for the traction hook 200, and further improving the stability and correction effect of the entire orthodontic appliance.

[0028] The traction hook 200 of this utility model is formed by bending a first steel wire, and one end of the traction hook is fixed to the connecting rod 600. The bent end of the first steel wire extends to the back of the permanent tooth 800 to be corrected.

[0029] One end of the tongue 500 is fixedly mounted inside the connecting device 300, while the other end of the tongue 500 is located outside the connecting device 300. Multiple tongues 500 are provided, and each tongue 500 is a symmetrical structure formed by bending a second steel wire, such as... Figure 3 Both ends of the second steel wire are fixedly embedded inside the connecting device 300, and the middle part of the second steel wire is located outside the connecting device 300.

[0030] The connecting device 300 is a Nance bow. The two ends of the palatal arch in the Nance bow are fixedly connected to the first band 100 and the second band 100, respectively; the two ends of the second steel wire are fixedly embedded inside the palatal support in the Nance bow.

[0031] It should be noted that the tongue rail 500 of this invention forms an contact area with the tongue 700 inside the oral cavity, preventing the tongue 700 from unintentionally protruding forward, thereby avoiding bad habits such as tongue protrusion, teeth licking, thumb sucking, and primary tongue thrusting. When the user needs to speak or protrude the tongue 700, they only need to actively move the tongue 700 across the tongue rail 500 for normal movement. "Unintentionally protruding forward" refers to the direction in which the tongue 700 extends from the incisors. The number of tongue rails 500 in this orthodontic appliance can be set to 2, 3, 5, etc., depending on the actual situation. This embodiment uses 6 tongue rails 500 as an example for explanation. It should also be noted that each tongue rail 500 is formed by bending a steel wire to create a smooth surface, protecting the tongue 700 from injury.

[0032] The method of using the permanent tooth eruption direction orthodontic appliance of this utility model is as follows: When the permanent tooth has partially erupted, such as when the crown is ≤1 / 3 exposed, the fixing hook 400 is directly glued to the exposed crown surface to ensure a firm fixation. Then, the traction hook 200 extends from the band 100 to the back of the permanent tooth, with its end aligned with the position of the fixing hook 400. If the permanent tooth 800 to be corrected is completely impacted in the alveolar bone, part of the crown is surgically exposed, and then the fixing hook 400 is glued to the crown surface, so that the traction hook 200 extends from the band 100 to the corresponding alveolar bone lateral side, with its end pointing to the back of the impacted position of the permanent tooth, ensuring that the direction of the pulling force is consistent with the expected eruption path. Then, the traction hook 200 and the fixing hook 400 are connected by the connector 900.

[0033] This orthodontic appliance consists of multiple bands 100 that are fitted onto either deciduous or permanent teeth. The first band 100 on the left and the second band 100 on the right are each connected by a connecting rod 600 to form a single-sided integral structure. These are then connected by a connecting device 300 to form a transmaxillary frame. A traction hook 200 provides directional traction to the permanent tooth 800 to be corrected. A lingual rail 500 creates a contact area with the tongue 700. The beneficial effects of this orthodontic appliance are: 1. Multiple fixed points distribute force, preventing single deciduous teeth from loosening or falling out due to excessive local force, thus improving force stability; 2. The single-sided integral structure ensures synchronized force on both teeth, reducing force deviation and improving the control accuracy of the eruption direction of permanent teeth; 3. It adapts to differences between the upper and lower jaws, meeting the personalized correction needs of different jaw positions; 4. It prevents the tongue 700 from inadvertently protruding forward, thereby avoiding bad habits such as tongue thrusting, teeth licking, thumb sucking, and primary tongue protrusion, thus improving the correction effect.

[0034] Example 2 A type of orthodontic appliance, such as Figure 4 As shown, other features are the same as in Embodiment 1, except that: there are two traction hooks 200, each traction hook 200 is respectively used to pull the permanent tooth 800 to be corrected, and the two traction hooks 200 are integrally connected to the first band 100 and the second band 100 respectively.

[0035] Compared with Example 1, the permanent tooth eruption direction orthodontic appliance in this example can simultaneously pull two permanent teeth 800 to be corrected, improving the orthodontic efficiency of multiple abnormal eruptions of permanent teeth.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
