Description

Technical Field

[0001] The invention relates to the technical field of oral orthodontic appliances, in particular to a detachable impacted molar correction device. Background Art

[0002] In orthodontic treatment, the correction of impacted molars has always been a challenging problem. Among the existing correction devices, the method of simply relying on the tension generated by the bending of the steel wire to support the impacted molars on both sides is widely used. However, this method has gradually exposed many disadvantages in practical applications.

[0003] On the one hand, the material and structural characteristics of the bent steel wire determine that it is prone to irreversible deformation when it is subjected to long-term force. This deformation will gradually weaken the tension originally generated by the steel wire, and gradually reduce the corrective effect on impacted molars.

[0004] On the other hand, due to the complex oral environment of the human body, daily activities such as chewing and swallowing will have a continuous impact on the orthodontic device. Over time, the originally tightened steel wire may become loose, causing the orthodontic device to be unable to function stably, and may even deviate from the preset correction position, affecting the progress and effect of the correction.

[0005] In addition, loose wires may irritate oral tissues, causing discomfort and pain to patients. Moreover, once loose wires occur, frequent adjustments and repairs are often required, increasing patients' treatment time and economic costs.

[0006] In summary, the existing impacted molar correction devices that rely solely on wire bending to generate tension have serious deficiencies in stability and reliability during long-term use and are in urgent need of improvement and innovation. Summary of the invention

[0007] In order to overcome the existing problems, an embodiment of the present application provides a detachable impacted molar correction device, which includes an adjustment component, a tensioning component is provided at both ends of the adjustment component, and a support component is provided under the two tensioning components. The adjustment component includes a rotating shaft, and a screw rod is provided at both ends of the rotating shaft. The screw rod is driven to rotate by rotating the rotating shaft, so that the tensioning force of the tensioning components on both sides can be changed, which effectively avoids loosening and weakening of the correction force due to long-term use, ensures the stability and durability of the correction effect, reduces the uncertainty in the correction process, and greatly enhances the long-term stability and reliability of the correction device.

[0008] The technical solution adopted by the embodiment of the present application to solve the technical problem is: A detachable impacted molar correction device comprises an adjustment component, wherein both ends of the adjustment component are provided with a tensioning component, the tensioning component is made of a material with good elasticity and toughness, such as nickel-titanium alloy, and a support component is provided below the two tensioning components, the support component is made of a material with good stability and high biocompatibility, such as medical-grade polyethylene, and the shape and size of the support component are optimized according to the oral anatomical structure; Among them, the adjusting component includes a rotating shaft, and the rotating shaft is made of high-strength and wear-resistant metal material, such as titanium alloy or stainless steel. A first screw rod and a second screw rod are respectively provided at both ends of the rotating shaft. The thread precision of the first screw rod and the second screw rod is high, and the surface is smoothed. The first screw rod and the second screw rod are respectively connected to the tensioning components on both sides. Adjusting the adjusting component is used to change the tensioning force of the tensioning component. When the tensioning force of the protective frames on both sides needs to be changed, when the rotating shaft is rotated at this time, the first screw rod and the second screw rod at both ends of the rotating shaft rotate accordingly. Since the connecting columns at both ends of the first screw rod and the second screw rod are connected to the tensioning component, the rotational motion of the first screw rod and the second screw rod is converted into the linear motion of the tensioning component, thereby changing the tensioning force applied by the tensioning component to the impacted molar.

[0009] Preferably, the tensioning assembly includes a cross bar connected to the adjustment assembly, a bent rod is provided at one end of the cross bar, a protective frame is provided at the other end of the bent rod, the protective frame is a U-shaped structure, and the edges and corners of the protective frame are smoothed for contact with the teeth.

[0010] Preferably, a protective pad is provided on the lower surface of the support component. The protection of the protective pad can avoid damage to the oral cavity, so that the correction device can be used according to the patient's specific situation and correction process. The support component and the protective pad are detachable structures. A connecting rod is provided at the intersection of the support component and the protective pad. A support rod is provided at each end of the connecting rod and the connection with the tensioning component. The two support rods inside the support component are fixedly connected to the tensioning component.

[0011] Preferably, the first screw rod and the second screw rod are each provided with a connecting column at one end away from the rotating shaft, and the connecting column is connected to the tensioning assembly. The first screw rod and the second screw rod are fixedly connected to the rotating shaft, and the first screw rod and the second screw rod are threadedly connected to the connecting column. The rotation operation of the rotating shaft is convenient. Since the rotating shaft and the first screw rod and the second screw rod are fixed to each other, the rotating shaft can drive the first screw rod and the second screw rod to rotate during rotation, so as to adjust the tensioning force of the tensioning assembly at both ends.

[0012] The advantages of the embodiments of the present application are: 1. The device includes an adjustment component, a tensioning component is provided at both ends of the adjustment component, and a support component is provided under the two tensioning components. The adjustment component includes a rotating shaft, and screw rods are provided at both ends of the rotating shaft. The screw rods are driven to rotate by rotating the rotating shaft, so that the tensioning force of the tensioning components on both sides can be changed, which effectively avoids loosening and weakening of correction force due to long-term use, ensures the stability and durability of the correction effect, reduces the uncertainty in the correction process, and greatly enhances the long-term stability and reliability of the correction device.

[0013] 2. Since the adjustment component can change the force of the tensioning components on both sides, personalized and precise correction is achieved.

The support component 3 is made of a material with good stability and high biocompatibility, such as medical-grade polyethylene, and the shape and size of the support component 3 are optimized according to the anatomical structure of the oral cavity; Among them, the adjustment component 1 includes a rotating shaft 11, which is made of high-strength and wear-resistant metal materials, such as titanium alloy or stainless steel.

The adjustment component 1 is adjusted to change the tensioning force of the tensioning component 2. When the tensioning force of the protective frames 32 on both sides needs to be changed, when the rotating shaft 11 is rotated at this time, the first screw rod 12 and the second screw rod 13 at both ends of the rotating shaft 11 rotate accordingly. Since the connecting columns 14 at both ends of the first screw rod 12 and the second screw rod 13 are connected to the tensioning component 2, the rotational motion of the first screw rod 12 and the second screw rod 13 is converted into the linear motion of the tensioning component 2, thereby changing the tensioning force applied by the tensioning component 2 to the impacted molar.

[0022] The tensioning assembly 2 includes a cross bar 21 connected to the adjustment assembly 1, a bending rod 22 is provided at one end of the cross bar 21, and a protective frame 23 is provided at the other end of the bending rod 22.

The rotation operation of the rotating shaft 11 is convenient. Since the rotating shaft 11 and the first screw rod 12 and the second screw rod 13 are fixed to each other, the rotating shaft 11 can drive the first screw rod 12 and the second screw rod 13 to rotate during rotation, so as to adjust the tensioning force of the tensioning assembly 2 at both ends.

[0026] During the installation process, the doctor carefully adjusted the various components of the device into place so that the protective frame 23 inside the tensioning assembly 2 was in good contact with the impacted molar. During the subsequent correction period, the doctor could adjust the tensioning force by rotating the rotating shaft 11 at any time according to the patient's follow-up situation and actual needs. The patient's impacted molars gradually returned to their original positions, the correction effect was significant, and the patient did not feel obvious discomfort during the whole process. Example 2

The support component 3 is made of a material with good stability and high biocompatibility, such as medical-grade polyethylene, and the shape and size of the support component 3 are optimized according to the anatomical structure of the oral cavity; Among them, the adjustment component 1 includes a rotating shaft 11, which is made of high-strength and wear-resistant metal materials, such as titanium alloy or stainless steel. A first screw rod 12 and a second screw rod 13 are respectively provided at both ends of the rotating shaft 11. The thread precision of the first screw rod 12 and the second screw rod 13 is high, and the surface is smoothed. The first screw rod 12 and the second screw rod 13 are respectively connected to the tensioning components 2 on both sides. The adjustment component 1 is adjusted to change the tensioning force of the tensioning component 2. When the tensioning force of the protective frames 32 on both sides needs to be changed, when the rotating shaft 11 is rotated at this time, the first screw rod 12 and the second screw rod 13 at both ends of the rotating shaft 11 rotate accordingly. Since the connecting columns 14 at both ends of the first screw rod 12 and the second screw rod 13 are connected to the tensioning component 2, the rotational motion of the first screw rod 12 and the second screw rod 13 is converted into the linear motion of the tensioning component 2, thereby changing the tensioning force applied by the tensioning component 2 to the impacted molar.

[0028] The tensioning assembly 2 includes a cross bar 21 connected to the adjustment assembly 1, a bending rod 22 is provided at one end of the cross bar 21, and a protective frame 23 is provided at the other end of the bending rod 22.

[0030] The first screw rod 12 and the second screw rod 13 are each provided with a connecting column 14 at one end away from the rotating shaft 11, and the connecting column 14 is connected to the tensioning assembly 2. The first screw rod 12 and the second screw rod 13 are fixedly connected to the rotating shaft 11, and the first screw rod 12 and the second screw rod 13 are threadedly connected to the connecting column 14. The rotation operation of the rotating shaft 11 is convenient. Since the rotating shaft 11 and the first screw rod 12 and the second screw rod 13 are fixed to each other, the rotating shaft 11 can drive the first screw rod 12 and the second screw rod 13 to rotate during rotation, so as to adjust the tensioning force of the tensioning assembly 2 at both ends.

[0031] By adopting the above technical solution: In a professional orthodontic clinic, an adult patient presented with a complex case of impacted molars.

[0032] The orthodontic device is installed at a suitable position in the patient's oral cavity, so that the protective frame 23 inside the tensioning component 2 is in good contact with the impacted molar, and the protective frame 23 abuts against the impacted molar. After using the orthodontic device, timely adjustments are made according to the patient's tooth movement. The support component 3 provides stable support for the correction process. The patient's oral health is good, and the protection of the protective pad 4 can avoid damage to the oral cavity, so that the orthodontic device can be used according to the patient's specific situation and correction process. The overall structure is detachable, which provides great convenience for the patient's daily oral cleaning and maintenance, helps to maintain oral hygiene, and reduce complications caused by hygiene problems.

[0033] Here’s how it works: First, the correction device is installed at a suitable position in the patient's oral cavity, so that the protection frame 23 inside the tensioning assembly 2 is in good contact with the impacted molar, and the protection frame 23 abuts against the impacted molar.

[0034] After the installation is completed, when it is necessary to change the tensioning force of the protective frames 23 on both sides, when the rotating shaft 11 is rotated, the first screw rod 12 and the second screw rod 13 at both ends of the rotating shaft 11 rotate accordingly. Since the connecting columns 14 at both ends of the first screw rod 12 and the second screw rod 13 are connected to the tensioning assembly 2, the rotational motion of the first screw rod 12 and the second screw rod 13 is converted into the linear motion of the tensioning assembly 2, thereby changing the tensioning force applied by the tensioning assembly 2 to the impacted molar.

[0035] During the correction process, the rotating shaft 11 can be rotated at any time to adjust the tension according to actual needs. The support component 3 provides stable support at the bottom to share the correction force and ensure that the entire device maintains a stable position and state in the oral cavity. In addition, the protection of the protective pad 4 can avoid damage to the oral cavity, so that the correction device can flexibly and accurately adjust the tension according to the patient's specific situation and the correction process, thereby achieving effective correction of impacted molars.
