Description

Technical Field

[0001] The present invention relates to the technical field of orthodontic instruments, and particularly to a traction and expansion device for impacted maxillary anterior teeth and dental arch stenosis in children. Background Art

[0002] In the field of pediatric orthodontics, the treatment of impacted maxillary anterior teeth and dental arch stenosis has always been a matter of great concern. Among the currently commonly used traction devices, a rubber band, as the main source of traction force, is tied above the limiting component. However, due to the relatively fixed and inflexible connection method of fixing the limiting component and the bracket with screws, there are many drawbacks during the process of the rubber band applying traction force.

[0003] On the one hand, under the continuous traction force, the screw fixation method is likely to cause slight displacement and rotation of the limiting component. This imperceptible deviation gradually accumulates over time, which may lead to a change in the traction direction and fail to accurately act on the target tooth, thereby affecting the overall traction effect.

[0004] On the other hand, for pediatric patients, their oral structures are still in the developmental stage, and there are significant individual differences in the position and growth of teeth. However, the traditional fixation method cannot be flexibly adjusted according to the specific tooth conditions of each child, making it difficult to meet the traction requirements of impacted teeth in different positions and restricting the personalization and accuracy of treatment.

[0005] These problems not only increase the difficulty and uncertainty of treatment but also may prolong the treatment cycle, bringing more pain and inconvenience to pediatric patients. Therefore, there is an urgent need for a more stable, flexible, and accurate traction and expansion device to improve this situation. Summary of the Invention

[0006] In order to overcome the existing problems, the embodiments of the present application provide a traction and expansion device for impacted maxillary anterior teeth and dental arch stenosis in children. A sliding groove is opened at the intersection of the bracket and the limiting component, and a sliding block is provided at the corresponding position of the limiting component and the sliding groove, so that the limiting component can move up and down under the limiting action of the sliding block and the sliding groove, avoiding deviation during the traction of the rubber band, ensuring the accuracy and stability of traction, effectively avoiding the deviation of the limiting component under the traditional fixation method, ensuring that the traction force of the rubber band always accurately acts on the target tooth, and greatly improving the success rate of treatment.

[0007] The technical solution adopted by the embodiments of the present application to solve its technical problems is: A traction and expansion device for impacted maxillary anterior teeth and dental arch stenosis in children, comprising a bracket, a second abutting component is provided above the bracket, a first abutting component is provided below the bracket, and a limiting component is provided on one side of the bracket and located at the first abutting component; Wherein, a chute is provided at the intersection of the bracket and the limiting component, a sliding seat is provided at a position corresponding to the chute of the limiting component, a slider is provided inside the sliding seat, and the sizes and shapes of the slider and the chute are precisely designed to ensure smooth and stable sliding of the slider inside the chute. When it is necessary to change the limiting component by traction, the limiting component moves up and down along the chute through the slider, which avoids the deviation that may occur in the traditional fixing method, installs the bracket at a suitable position, and adjusts the second abutting component at the top end and the first abutting component at the bottom end of the bracket, so that the overall structure is fixed and stable under the action of the first abutting component and the second abutting component. During the traction process, the rubber band is clamped on the outer wall of the support rods on both sides of the limiting component, and the other end of the rubber band is connected to the teeth inside the oral cavity, and then the traction force generated by the rubber band acts on the limiting component.

[0008] Preferably, a through hole is further provided in the sliding seat inside the limiting component, and a support rod is provided at each end of the sliding seat, and rubber bands are sleeved on the outer walls of the two support rods.

[0009] Preferably, a plurality of connection holes are provided at positions corresponding to the limiting component on the bracket. By changing the connection between the connecting piece inside the limiting component and the connection holes at different positions, the positional relationship of the limiting component can be changed.

[0010] Preferably, the first abutting component includes a fixed seat, a side plate is provided at one end of the fixed seat, and a protective pad is provided at the end of the side plate away from the fixed seat. With the setting of the protective pad, it can be avoided that the first abutting component causes greater extrusion to the patient's face. A plug hole is provided at the connection between the fixed seat and the bracket, and the plug hole is connected through the bracket. By changing the positional relationship between the bracket and the plug hole, the positional relationship of the first abutting component can be changed, and the cross-sectional diameter of the plug hole is the same as the cross-sectional diameter of the bracket.

[0011] Preferably, a plurality of threaded holes are provided at positions corresponding to the first abutting component and the second abutting component on the bracket. The first abutting component and the second abutting component can both slide up and down inside the bracket. Connecting pieces are provided inside the first abutting component and the second abutting component and penetrate through the first abutting component and the second abutting component to be connected to the threaded holes. When it is necessary to change the positional relationship between the first abutting component and the second abutting component and the bracket, the connecting pieces inside the first abutting component and the second abutting component are separated from the threaded holes, and then the first abutting component and the second abutting component are respectively moved so that the first abutting component and the second abutting component correspond to the threaded holes at different positions, and then the connecting pieces are fixed to change the positions of the first abutting component and the second abutting component.

[0012] Preferably, the bracket is of a bent structure. With the bent bracket, it can better adapt to the facial conditions of patients. At the bottom end of the bracket where it is located at the first abutting component, there is a first plug, and at the top end of the bracket where it is located at the second abutting component, there is a second plug. By connecting the first plug and the second plug to the bracket, the first abutting component and the second abutting component inside the bracket can be limited in position.

[0013] The advantages of the embodiments of the present application are as follows: 1. A chute is opened at the intersection of the bracket and the limiting component, and a slider is arranged at the corresponding position of the limiting component and the chute, so that the limiting component can move up and down under the limiting action of the slider and the chute, avoiding deviation during the traction process of the rubber band, ensuring the accuracy and stability of the traction, effectively avoiding the deviation of the limiting component under the traditional fixing method, ensuring that the traction force of the rubber band always acts accurately on the target tooth, and greatly improving the success rate of treatment.

[0014] 2. A connecting piece is arranged on the outer wall of the limiting component, and a plurality of connecting holes are opened on the outer wall of the bracket. By changing the connection between the connecting piece inside the limiting component and the connecting holes at different positions, the position of the limiting component can be flexibly adjusted according to the specific tooth conditions of different child patients, meeting the traction and expansion requirements of impacted teeth in various different positions, and realizing personalized and precise treatment.

[0020] The overall idea of the technical solutions in the embodiments of the present application to solve the above problems is as follows: Embodiment 1

[0021] This embodiment gives the specific structure of a traction and expansion device for impacted maxillary anterior teeth and dental arch stenosis in children, as Figures 1-4 shown, including a bracket 1, a second abutting component 4 is arranged above the bracket 1, a first abutting component 3 is arranged below the bracket 1, and a limiting component 2 is arranged on one side of the bracket 1 where the first abutting component 3 is located; Among them, a chute 5 is provided at the intersection of the bracket 1 and the limit component 2. A sliding seat 21 is provided at the corresponding position of the limit component 2 and the chute 5. A slider 24 is arranged inside the sliding seat 21. The sizes and shapes of the slider 24 and the chute 5 are precisely designed to ensure the smooth and stable sliding of the slider 24 inside the chute 5. When it is necessary to change the limit component 2 by traction, the limit component 2 moves up and down along the chute 5 through the slider 24, which avoids the deviation that may occur in the traditional fixing method. The bracket 1 is installed at a suitable position, and the second abutting component 4 at the top end and the first abutting component 3 at the bottom end of the bracket 1 are adjusted so that the overall structure is fixed stably under the action of the first abutting component 3 and the second abutting component 4. During the traction process, a rubber band is clamped on the outer wall of the support rod 22 on both sides of the limit component 2, and the other end of the rubber band is connected to the teeth inside the oral cavity. Then, the traction force generated by the rubber band acts on the limit component 2.

One end of the fixed seat 32 is provided with a side plate 31, and a protective pad 33 is provided at the end of the side plate 31 away from the fixed seat 32.

A plug hole 34 is provided at the connection between the fixed seat 32 and the bracket 1, and the plug hole 34 is connected through the bracket 1. By changing the positional relationship between the bracket 1 and the plug hole 34, the positional relationship of the first abutting component 3 can be changed. The cross-sectional diameter of the plug hole 34 is the same as the cross-sectional diameter of the bracket 1.

[0025] A number of threaded holes 9 are provided at the corresponding positions of the bracket 1 with respect to the first abutting component 3 and the second abutting component 4. Both the first abutting component 3 and the second abutting component 4 can slide up and down inside the bracket 1. Connecting pieces are provided inside both the first abutting component 3 and the second abutting component 4, and they penetrate through the first abutting component 3 and the second abutting component 4 and are connected to the threaded holes 9. When it is necessary to change the positional relationship between the first abutting component 3 and the second abutting component 4 and the bracket 1, the connecting pieces inside the first abutting component 3 and the second abutting component 4 are separated from the threaded holes 9, and then the first abutting component 3 and the second abutting component 4 are respectively moved so that the first abutting component 3 and the second abutting component 4 correspond to the threaded holes 9 at different positions. After that, the connecting pieces are fixed to change the positions of the first abutting component 3 and the second abutting component 4.

At the bottom end of the bracket 1 where it is located at the first abutting component 3, there is a first plug 7. At the top end of the bracket 1 where it is located at the second abutting component 4, there is a second plug 8. By connecting the first plug 7 and the second plug 8 to the bracket 1, the first abutting component 3 and the second abutting component 4 inside the bracket 1 can be limited.

[0027] By adopting the above technical solution: In a professional oral hospital, a little boy came to see a doctor due to impacted maxillary anterior teeth and dental arch stenosis.

[0028] The doctor selected the traction and arch expansion device of the present invention for him, installed the bracket 1 at a suitable position, and adjusted the second abutting component 4 at the top end and the first abutting component 3 at the bottom end of the bracket 1, so that the overall structure is fixed and stable under the action of the first abutting component 3 and the second abutting component 4. During the traction process, the rubber band is clamped on the outer wall of the support rods 22 on both sides of the limiting component 2, and the other end of the rubber band is connected to the teeth inside the oral cavity. After that, the traction force generated by the rubber band acts on the limiting component 2. According to the position of the impacted tooth of the child, the connecting piece of the limiting component 2 is adjusted to be connected to the appropriate connecting hole 6. During the subsequent treatment process, the little boy wears it comfortably, the traction effect is good, the impacted tooth gradually returns to its place, and the dental arch is also effectively expanded. Embodiment 2

[0029] This embodiment gives the specific structure of a traction and arch expansion device for impacted maxillary anterior teeth and dental arch stenosis in children, as Figures 1-4 shown, including a bracket 1. There is a second abutting component 4 above the bracket 1, a first abutting component 3 below the bracket 1, and a limiting component 2 is provided on one side of the bracket 1 where it is located at the first abutting component 3; Among them, a sliding groove 5 is provided at the intersection of the bracket 1 and the limiting component 2. A sliding seat 21 is provided at the corresponding position of the limiting component 2 and the sliding groove 5. A slider 24 is provided inside the sliding seat 21. The sizes and shapes of the slider 24 and the sliding groove 5 are precisely designed to ensure the smooth and stable sliding of the slider 24 inside the sliding groove 5. When it is necessary to change the limiting component 2 through the traction force, the limiting component 2 moves up and down along the sliding groove 5 through the slider 24, which avoids the deviation that may occur in the traditional fixing method. The bracket 1 is installed at a suitable position, and the second abutting component 4 at the top end and the first abutting component 3 at the bottom end of the bracket 1 are adjusted, so that the overall structure is fixed and stable under the action of the first abutting component 3 and the second abutting component 4. During the traction process, the rubber band is clamped on the outer wall of the support rods 22 on both sides of the limiting component 2, and the other end of the rubber band is connected to the teeth inside the oral cavity. After that, the traction force generated by the rubber band acts on the limiting component 2.

[0030] The sliding seat 21 inside the limiting component 2 is also provided with a through hole 23. A support rod 22 is provided at each end of the sliding seat 21, and rubber bands are sleeved on the outer walls of the two support rods 22.

[0031] A number of connecting holes 6 are provided at the corresponding position of the bracket 1 with respect to the limiting component 2. By changing the connection between the internal connecting piece of the limiting component 2 and the connecting holes 6 at different positions, the positional relationship of the limiting component 2 can be changed.

[0032] The first abutting component 3 includes a fixed seat 32. One end of the fixed seat 32 is provided with a side plate 31, and a protective pad 33 is provided at the end of the side plate 31 away from the fixed seat 32. With the arrangement of the protective pad 33, it is possible to prevent the first abutting component 3 from causing excessive extrusion to the patient's face. A plug hole 34 is provided at the connection between the fixed seat 32 and the bracket 1, and the plug hole 34 is connected through the bracket 1. By changing the positional relationship between the bracket 1 and the plug hole 34, the positional relationship of the first abutting component 3 can be changed. The cross-sectional diameter of the plug hole 34 is the same as the cross-sectional diameter of the bracket 1.

[0033] A number of threaded holes 9 are provided at the corresponding positions of the bracket 1 with respect to the first abutting component 3 and the second abutting component 4. Both the first abutting component 3 and the second abutting component 4 can slide up and down inside the bracket 1. Connecting pieces are provided inside both the first abutting component 3 and the second abutting component 4, and they penetrate through the first abutting component 3 and the second abutting component 4 and are connected to the threaded holes 9. When it is necessary to change the positional relationship between the first abutting component 3 and the second abutting component 4 and the bracket 1, separate the connecting pieces inside the first abutting component 3 and the second abutting component 4 from the threaded holes 9, and then move the first abutting component 3 and the second abutting component 4 respectively, so that the first abutting component 3 and the second abutting component 4 correspond to the threaded holes 9 at different positions. After that, fixing the connecting pieces can change the positions of the first abutting component 3 and the second abutting component 4.

[0034] The bracket 1 is of a bent structure. With the bent bracket 1, it can better adapt to the facial conditions of the patient. A first plug 7 is provided at the bottom end of the bracket 1 where the first abutting component 3 is located, and a second plug 8 is provided at the top end of the bracket 1 where the second abutting component 4 is located. By connecting the first plug 7 and the second plug 8 to the bracket 1, the first abutting component 3 and the second abutting component 4 inside the bracket 1 can be limited.

[0035] By adopting the above technical solutions: In a children's dental clinic, a little girl was treated with this device.

[0036] The doctor installs the bracket 1 in a suitable position and adjusts the second abutting component 4 at the top end and the first abutting component 3 at the bottom end of the bracket 1, so that the overall structure is fixed and stable under the action of the first abutting component 3 and the second abutting component 4. During the traction process, the rubber band is clamped on the outer wall of the support rod 22 on both sides of the limiting component 2, and the other end of the rubber band is connected to the teeth inside the oral cavity. Then, the traction force generated by the rubber band acts on the limiting component 2. By flexibly adjusting the position of the limiting component 2, since there are chute 5 and slider 24 structures at the intersection of the bracket 1 and the limiting component 2, when it is necessary to change the position of the limiting component 2 through the traction force, the limiting component 2 can move up and down along the chute 5 through the slider 24, thus avoiding the deviation that may occur in the traditional fixing method, ensuring the accuracy and stability of the traction direction, and making it perfectly match the oral condition of the little girl. After a period of traction and arch expansion, the dental problems of the little girl have been significantly improved, and her smile has become more confident.

[0037] Working principle: First, install the bracket 1 in a suitable position and adjust the second abutting component 4 at the top end and the first abutting component 3 at the bottom end of the bracket 1, so that the overall structure is fixed and stable under the action of the first abutting component 3 and the second abutting component 4. During the traction process, the rubber band is clamped on the outer wall of the support rod 22 on both sides of the limiting component 2, and the other end of the rubber band is connected to the teeth inside the oral cavity. Then, the traction force generated by the rubber band acts on the limiting component 2.

[0038] Since there are chute 5 and slider 24 structures at the intersection of the bracket 1 and the limiting component 2, when it is necessary to change the position of the limiting component 2 through the traction force, the limiting component 2 can move up and down along the chute 5 through the slider 24, thus avoiding the deviation that may occur in the traditional fixing method, ensuring the accuracy and stability of the traction direction.

[0039] At the same time, by changing the connection between the connecting piece on the outer wall of the limiting component 2 and the connecting holes 6 at different positions on the outer wall of the bracket 1, the position of the limiting component 2 can be adjusted to meet the traction and arch expansion requirements of impacted teeth at different positions, so that the device can be flexibly adjusted according to the specific oral conditions of each child patient, realizing precise and effective traction and arch expansion treatment.

[0040] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
