Description

Technical Field

[0001] The present invention relates to the field of oral medical technology, and in particular to a tooth correction auxiliary device. Background Art

[0002] During the process of human growth and development, various types of malocclusion may occur due to congenital or acquired reasons.

[0003] Orthodontic treatment mainly uses various corrective devices to adjust the balance and coordination between facial bones, teeth, and maxillofacial nerves and muscles, ultimately achieving balance, stability, and beauty of the oral and maxillofacial system. The correction of malocclusion mainly relies on wearing braces inside or outside the mouth to apply appropriate "bioforce" to the teeth, alveolar bones, and jaws to produce physiological movement, thereby correcting the malocclusion. The principle of orthodontic tooth movement is that under the action of the corrective force, the periodontal ligament is compressed, and its osteoclasts and osteoblasts are activated and penetrate into the periodontal ligament (periodontal membrane), and then the alveolar bone is remodeled, so that the alveolar bone on the compressed side is absorbed, and the alveolar bone on the distraction side is regenerated, thereby causing the teeth to move.

[0004] The rate of orthodontic tooth movement is limited by the speed of bone remodeling, so the course of orthodontic treatment is generally long, usually about 2 years. Obviously, orthodontic treatment is not a very comfortable process. The negative effects on appearance, eating, cleaning, and tooth discomfort after force application will prompt patients to shorten the entire course of treatment as much as possible.

[0005] Therefore, in order to speed up the correction efficiency of orthodontic devices and relieve the pain of patients, people have invented auxiliary devices for tooth correction. For example, in the Chinese patent application document with application number 201610162257.6, a tooth brace is disclosed, which is essentially an auxiliary device for tooth correction.

[0006] The main principle of this auxiliary device for orthodontic treatment is that when the patient's teeth contact the dental tray of the device, the vibration of a specific frequency is transmitted to the teeth through contact, thereby promoting the reconstruction of the alveolar bone and increasing the movement rate of the teeth. Clinical data show that using a device based on this principle to continuously vibrate the teeth every day can increase the tooth movement rate by 20% to 50%.

[0007] However, in the prior art, the dental tray is usually a whole with uniform specifications and size, and contacts and acts on the entire dentition. Although such a design seems convenient, it will bring many problems in actual clinical use. First, due to the great differences in the size and shape of each patient's dental arch, the uniform tray specifications cannot adapt well to different patients, and insufficient or poor contact will affect its effect; secondly, the tooth movement targets in different areas are often different. In common tooth extraction cases, the front teeth need to be aligned and retracted as quickly as possible, while the posterior teeth as support generally need to slow down their movement or even try to stay still. At this time, applying the same vibration to the front and back teeth may cause the supporting posterior teeth to move too quickly, resulting in undesirable "loss of support" and affecting the final orthodontic effect; finally, the most suitable vibration amplitude and frequency for different tooth movement methods may be different, and the vibration method that cannot be adjusted is often not suitable for all types of malocclusion. Summary of the invention

[0008] The purpose of the present invention is to provide a tooth correction auxiliary device, which can accelerate the correction of teeth in a deformed state in a targeted manner.

[0009] Specifically, in order to solve the above problems, the present invention provides a tooth correction auxiliary device, comprising: a shell, a vibration device arranged in the shell, and a connecting member with a part located inside the shell and the rest located outside the shell, wherein the vibration device is used to generate vibration,

[0010] A connecting portion is provided at one end of the connecting piece located outside the shell;

[0011] The orthodontic auxiliary device also includes a dental tray assembly detachably connected to the connecting portion, wherein the dental tray assembly includes a plurality of trays and each tray is responsible for a portion of the tooth area.

[0012] The vibration generated by the vibration device of the present invention can drive the dental tray assembly to vibrate, thereby achieving the effect of assisting orthodontics.

[0013] The present invention can achieve auxiliary correction of deformed teeth in different parts of the oral cavity by selecting trays corresponding to the areas that need correction. The positions of the remaining normal teeth do not need to be installed with trays to avoid being affected by the vibration of the vibration device. In the present invention, different trays can be selected in different correction stages to achieve coordination of tooth correction speeds in different oral areas. Therefore, compared with the prior art, the present invention can avoid the hidden dangers caused by the simultaneous vibration of the entire oral cavity, and can adjust the treatment plan in an individualized manner according to the actual situation of the patient.

[0014] Preferably, the dental tray assembly comprises at least: a tray located in the middle, which is responsible for the vibration of the front teeth area;

[0015] The tray located on the left wing is responsible for the vibration of the left posterior tooth area;

[0016] The tray located on the right wing is used to take care of the vibrations in the right posterior tooth area.

[0017] The connecting piece is used to connect the dental tray assembly and the vibration device, and transmit the vibration to the dental tray assembly. Since the deformity and displacement of teeth affect each other, generally speaking, the deformity occurs in a large area. In this embodiment, the dental tray is divided into three trays, each of which is responsible for the vibration of three large areas, which is sufficient to meet the needs of patients in most cases.

[0018] Further, as a preference, the tray located in the middle is detachably connected to the middle portion of the connecting portion, the tray located on the left wing is detachably connected to the left portion of the connecting portion, and the tray located on the right wing is detachably connected to the right portion of the connecting portion.

[0019] The three trays are detachably connected to the corresponding parts of the connecting part, so that they can be combined as needed, the connection strength can be well guaranteed, and the structure is very simple, so it is very convenient.

[0020] Alternatively, the tray located in the middle portion may also be detachably connected to the connecting portion, and the tray located on the left wing and the tray located on the right wing may be detachably connected to the tray located in the middle portion, respectively.

[0021] When the pallets on the left and right wings are connected to the pallet in the middle, the pallet in the middle can occupy a larger coverage area, so it can have better adaptability.

[0022] Further, as a preference, the tray comprises an alveolar portion for occluding teeth, and an extension portion connected to the alveolar portion;

[0023] The extension part is detachably connected to the connection part.

[0024] When the extension part and the connection part are detachably connected, the tray can be selected and combined according to actual needs. In addition, since there is a long-term vibration effect during use, the extension part can be arranged in a form with a certain elasticity to ensure the connection strength.

[0025] Further, as a preference, the extension portion and the connection portion overlap each other, and screw holes are provided at corresponding positions of the overlapping region;

[0026] The extended part and the connecting part are fixed to each other by bolts.

[0027] The extension part and the connection part are overlapped and joined together, so that the bolt can pass through the bolt hole smoothly, and then the two are fixed to each other with bolts and nuts, so that the dental tray and the following parts become a whole. At the same time, the tight connection can prevent the tray from loosening or falling during use.

[0028] In the present invention, bolt connection has its special advantages. The bolt connection structure is not only stable and reliable, but also each tray can be independently connected to the connection part by bolts without padding, so it is more suitable for the application scenario of the present invention.

[0029] In addition, as a preference, a protrusion is formed on the extension portion, and a track groove is formed on the connection portion;

[0030] The protrusion is embedded in the track groove and fixes the extension part and the connection part to each other.

[0031] When the tray is fixed to the connection part in the form of a protrusion embedded in the track groove, the fixing operation is simpler and no special tools are required. Therefore, it is suitable for patients to install and change the tray for use at home.

[0032] Further, as a preference, a stop switch for locking the protrusion of the extended portion of each tray in the track groove is also provided at a position close to both ends of the track groove on the connecting portion.

[0033] Stop switches are arranged at both ends of the track groove to prevent the protrusion from sliding in the track groove during vibration and to prevent the protrusion from falling off the track groove, thereby making the connection between the two more stable.

[0034] In addition, as a preference, the dental tray assembly further comprises a plurality of replacement components; the replacement components are used to replace the tray to occupy the track groove.

[0035] The track groove can be filled by utilizing the combination of the replacement component and the tray. When further combined with the stop switch, the protrusion can be better prevented from moving in the track groove, thereby enhancing the fixing effect.

[0036] In addition, preferably, the alveolar portion is produced by 3D printing based on the patient's oral scan results.

[0037] Through 3D printing, the dental tray can be customized at a low cost to meet the tooth shape and oral needs of different patients and improve comfort. In addition, through the customized dental tray components for correction, it can better ensure that the correction results match the patient's own conditions.

[0038] In addition, as a preferred embodiment, the vibration device includes a motor and an eccentric wheel connected in series to the motor; the motor drives the eccentric wheel to rotate and generate vibration;

[0039] One end of the connecting piece located outside the housing is sleeved on the eccentric wheel;

[0040] The eccentric wheel drives the connecting piece to vibrate and transmits the vibration to the dental tray assembly.

[0041] The main principle of the vibration device is that the motor drives the eccentric wheel connected in series to the motor to rotate and generate vibration. The frequency of the vibration can be adjusted by adjusting the frequency of the motor rotation to achieve the purpose of controlling the vibration frequency. The end of the connecting piece located outside the shell is arranged on the eccentric wheel, and the vibration of the eccentric wheel can be directly transmitted to the connecting piece, thereby improving the transmission efficiency of the vibration.

[0042] In addition, as a preferred embodiment, the connecting piece is connected to the housing, and the vibration generated by the vibration device is transmitted to the connecting piece through the housing, and then to the dental tray assembly. By transmitting the vibration through the housing, the vibration is gentler and more comfortable than directly transmitting the vibration through the connecting piece.

DETAILED DESCRIPTION

[0059] The present invention will be further described in detail below in conjunction with the accompanying drawings of the specification. The accompanying drawings schematically and simply show the structure of the tooth correction auxiliary device.

[0060] Implementation Method 1

[0061] The first embodiment of the present invention provides a tooth correction auxiliary device, see Figure 1 and Figure 2 As shown, it comprises: a housing 1 and a vibration device 2 arranged in the housing 1, the vibration device 2 is used to generate vibration;

[0062] See also Figure 2 As shown, the vibration device 2 is implemented by any device capable of generating reciprocating motion in the prior art. Typically, it may include a motor 2a and an eccentric wheel 2b connected in series to the motor 2a; the motor 2a drives the eccentric wheel 2b to rotate and generate periodic vibration. The motor 2a may be any motor in the prior art, and in particular, may be a linear motor.

[0063] See also Figure 3As shown, the tooth correction auxiliary device further includes a connecting member 4 with a portion located inside the housing 1 and the rest located outside the housing 1, and a connecting portion 4a is provided at one end of the connecting member 4 located outside the housing 1;

[0064] And, a dental tray assembly 3 detachably connected to the connecting portion 4a, the dental tray assembly 3 includes a plurality of trays 3a and each tray 3a is responsible for a part of the tooth area.

[0065] Specifically, the dental tray assembly 3 may include at least: a tray 3a located in the middle, which is detachably connected to the middle part of the connecting part 4a and is used to be responsible for the vibration of the front teeth area;

[0066] The tray 3a located on the left wing is detachably connected to the left side of the connecting part 4a and is responsible for the vibration of the left rear tooth area;

[0067] The tray 3a located on the right wing is detachably connected to the right side of the connecting portion 4a and is used to be responsible for the vibration of the right posterior tooth area.

[0068] The rest of the connecting member 4 except the connecting portion 4a can be connected to the inner surface of the housing 1 to facilitate the transmission of vibration.

[0069] The connecting member 4 is used to connect the dental tray assembly 3 and the vibration device 2, and transmit the vibration to the dental tray assembly 3. Since the deformity and displacement of teeth will affect each other, generally speaking, the deformity occurs in large areas. In this embodiment, the dental tray assembly 3 is divided into three trays 3a, and each is responsible for the vibration of three large areas, which is enough to adapt to the patient's condition in most cases. Obviously, it is not limited to being divided into three trays 3a. When encountering patients with special needs, the dental tray assembly 3 can also be customized according to actual conditions. Therefore, the number of trays 3a and the responsible area can be adjusted according to actual conditions. Taking into account the mechanical strength of the tray 3a, the vibration effect and the cost, it is a better choice to divide the tray 3a into two to four.

[0070] Further, the tray 3a includes an alveolar portion 3a1 for occluding teeth, and an extension portion 3a2 connected to the alveolar portion 3a1;

[0071] The extension portion 3a2 is detachably connected to the connection portion 4a.

[0072] When the extension part 3a2 and the connecting part 4a are detachably connected, the tray 3a can be selected and combined according to actual needs. In addition, since the extension part 3a2 is subjected to the influence of vibration for a long time during use, the extension part 3a2 can be configured to have a certain elasticity to ensure the connection strength.

[0073] Specifically for this embodiment, see Figure 5As shown, the extension portion 3a2 and the connecting portion 4a overlap each other, and screw holes 5a are provided at corresponding positions of the overlapping area;

[0074] The extended portion 3a2 and the connecting portion 4a are fixed to each other by bolts 5b.

[0075] The extension part 3a2 and the connection part 4a are joined together in an overlapping manner, so that the bolt 5b can pass through the screw hole 5a smoothly, and then the bolt 5b and the nut (not shown in the figure) are used to fix the two together, or directly through the bolt 5b and the thread in the screw hole 5a. At the same time, the tight connection can prevent the tray 3a from loosening and falling during use.

[0076] In the present invention, the bolt 5b connection has its special advantages. The bolt 5b connection structure is not only stable and reliable, but also each tray 3a can be independently connected to the connection part 4a by the bolt 5b without the need for padding, so it is very suitable for the application scenario of the present invention.

[0077] In this embodiment, the connecting member 4 is connected to the housing 1, and the vibration generated by the vibration device 2 is transmitted to the connecting member 4 through the housing 1, and then transmitted to the dental tray assembly 3. Compared with transmitting the vibration directly through the connecting member 4, the vibration is softer and more comfortable by transmitting the vibration through the housing 1.

[0078] In addition, in this embodiment, the alveolar portion 3a1 may be as follows Figure 3 The shapes shown in the figure can also be made using 3D printing based on the patient's oral scan results.

[0079] Through 3D printing, the dental tray can be customized at a low cost to meet the dental arch morphology and malocclusion types of different patients and improve comfort. In addition, correction through the customized dental tray assembly 3 can better ensure that the correction result matches the patient's own situation. Obviously, further, in order to ensure the structural strength of the alveolar part 3a1 and the extension part 3a2, the entire tray 3a can also be made in one piece through 3D printing.

[0080] This embodiment also provides an application of a tooth correction auxiliary device, and the process can be as follows:

[0081] 1. Install orthodontic devices for patients according to their condition.

[0082] 2. According to the type of malocclusion of the patient, the target tooth area that needs to be accelerated is designed according to the treatment plan, and the tray 3a of the corresponding area is installed on the connecting piece 4. For example, when the orthodontic movement of the teeth in the posterior tooth area on both sides of the patient needs to be accelerated, only the following can be installed: Figure 5The trays 3a shown are located at the left and right wings. During the installation process, the trays 3a to be installed can be directly connected to the connecting member 4 through the extension 3a2 by bolts 5b.

[0083] 3. Instruct the patient to bite the tooth tray area of ​​the device and turn on the switch of the vibration device 2, so that the vibration acts on the target tooth to accelerate its movement.

[0084] It is particularly worth mentioning that, for the present invention, the trays 3a included in the dental tray assembly 3 do not necessarily have to be all combined together to form a complete tooth correction contour. This is because, for different patients, the areas that require orthodontics may usually intersect near the canines or first premolars. The trays 3a located on the left and right wings are suitable for orthodontic auxiliary treatment of patients in the posterior tooth area up to the first premolar position. However, the tray 3a located in the middle that is connected to it as a set does not cover the position of the first premolar. For some patients who need orthodontic treatment from the incisors to the first premolar positions, it may not be enough to use the tray 3a located in the middle alone to assist orthodontics.

[0085] Therefore, in this embodiment, two trays 3a located in the middle can also be provided, one of which is as shown in FIG. Figure 3 The middle part is shown in Figure 4 As shown, the tray 3a in the middle thereof extends to the first premolar. The two can be replaced with each other to better adapt to complex clinical application scenarios.

[0086] The vibration emitted by the vibration device 2 of the present invention can drive the tooth tray assembly 3 to vibrate, thereby achieving the effect of assisting orthodontics. It is worth mentioning that in the present invention, the output power of the motor 2a can also be controlled by a circuit so that the frequency of the vibration can be adjusted. Thereby, the intensity of the vibration and the pulse mode can be adjusted in a targeted manner according to the patient's age, gender, type of malocclusion, and the movement mode of different teeth. The tooth correction auxiliary device provided by the present invention can not only be used for fixed correction, but also can be used in conjunction with invisible correction, and has a wide range of application prospects.

[0087] Based on the above considerations, the present invention can achieve auxiliary acceleration of teeth in different target areas in the oral cavity by selecting the corresponding trays 3a for the areas that need correction. For the support tooth area where the tooth movement acceleration is not desired, the tray 3a can be not installed to avoid being affected by the vibration of the vibration device 2. Even in the present invention, by selecting different trays 3a at different correction stages, the coordination of tooth correction speeds in different oral areas can be achieved. Therefore, compared with the prior art, the present invention can avoid the hidden dangers caused by the simultaneous vibration of the entire oral cavity, and can adjust the treatment plan in an individualized manner according to the actual situation of the patient.

[0088] Implementation Method 2

[0089] The second embodiment of the present invention provides a tooth correction auxiliary device. The second embodiment is different from the first embodiment. The main difference is that in the first embodiment of the present invention, the extension part 3a2 and the connecting part 4a are fixed to each other by bolts 5b; while in the second embodiment of the present invention, the extension part 3a2 and the connecting part 4a are fixed to each other by snapping.

[0090] Specifically, see Figure 6 As shown, in this embodiment, a protrusion 5c is formed on the extension portion 3a2, and a track groove 5d is formed on the connecting portion 4a;

[0091] See also Figure 7 As shown, the protrusion 5c is embedded in the track groove 5d and fixes the extension portion 3a2 and the connecting portion 4a to each other.

[0092] In this embodiment, the protrusion 5c and the track groove 5d are engaged with each other, so that the tray 3a can be well fixed on the connecting member 4. As a further preferred embodiment of this embodiment, a magnetic adsorption component can be provided at the corresponding position of the protrusion 5c and the track groove 5d, so as to facilitate the positioning of the protrusion 5c and the track groove 5d and prevent the protrusion 5c from slipping off the track groove 5d.

[0093] It is worth mentioning that in the present invention, the track groove 5d can be as follows Figure 6 , Figure 7 The shape of the rectangular groove shown may also be a dovetail groove or other shapes, and the specific shape features do not constitute a limitation on the protection scope of the present invention.

[0094] When the tray 3a is fixed to the connecting portion 4a by embedding the protrusion 5c into the track groove 5d, the fixing operation is simpler and does not require specific tools. Therefore, it is suitable for patients to install and replace the selected tray 3a at home.

[0095] Implementation Method 3

[0096] The third embodiment of the present invention provides a tooth correction auxiliary device. The third embodiment is a further improvement of the second embodiment. The main improvement is that in the third embodiment of the present invention, see Figure 8 As shown, stop switches 5f for locking the protrusions 5c of the extended portions 3a2 of each tray 3a in the track groove 5d are also provided at positions on the connecting portion 4a near both ends of the track groove 5d.

[0097] like Figure 8 As shown, when the stop switch 5f is turned on, the protrusion 5c can be easily embedded in the track groove 5d, and after each tray 3a is installed, see Fig. 9 As shown, by locking the stop switch 5f, the fixation of the tray 3a is completed.

[0098] Stop switches 5f are arranged at both ends of the track groove 5d to prevent the protrusion 5c from sliding in the track groove 5d during vibration, and to prevent the protrusion 5c from falling off from the track groove 5d, thereby making the connection between the two more stable.

[0099] Implementation Method 4

[0100] The fourth embodiment of the present invention provides a tooth correction auxiliary device. The fourth embodiment is a further improvement of the second or third embodiment. The main improvement is that in the fourth embodiment of the present invention, see Fig.10 , Fig.11 As shown, the dental tray assembly 3 further includes a plurality of replacement components 3b; the replacement components 3b are used to replace the tray 3a to occupy the track groove 5d.

[0101] The track groove 5d can be filled by the combination of the displacement member 3b and the tray 3a. When the stop switch 5f is further combined, the protrusion 5c can be better prevented from moving in the track groove 5d, thereby enhancing the fixing effect.

[0102] In the technical field of the present invention, the use of the replacement component 3b has its special advantages. This is because, since the severity of the patient's tooth deformity in different oral regions is different, it is necessary to select different tray 3a combinations at different times to make the orthodontic speed of each region different during the orthodontic process, and finally obtain a perfect orthodontic effect.

[0103] Therefore, in the present invention, by means of different replacement components 3b, the tray 3a in the track groove 5d can cover a variety of possible areas. Moreover, compared with the fixing method of bolts, too many fragmentary parts are not required, which is very suitable for patients to assemble and use at home.

[0104] Implementation Method 5

[0105] The fifth embodiment of the present invention provides a tooth correction auxiliary device, which is different from the first to fourth embodiments. The main difference is that in the first four embodiments of the present invention, the three trays 3a included in the dental tray assembly 3 are respectively connected to the left, middle and right positions of the connecting portion 4a; while in the fifth embodiment of the present invention, the trays 3a are connected to each other;

[0106] Specifically, in this embodiment, see Fig.12 As shown, the tray 3a located in the middle can be detachably connected to the connecting portion 4a of the connecting member 4, and the tray 3a located on the left wing and the tray 3a located on the right wing are detachably connected to the tray 3a located in the middle.

[0107] In this way, not every tray 3a needs to be provided with the extension part 3a2. For the trays 3a arranged on the left and right wings, it is entirely possible to only provide the alveolar part 3a1, which can be detachably connected to the tray 3a in the middle through various connection methods, and the two can form a complete alveolar.

[0108] For example, see Fig.12 As shown, the trays 3a located at the left and right wings can be connected to the tray 3a located in the middle by means of the buckle 3a3. Of course, other corresponding connection schemes, such as screw connection, are also allowed. There is no special limitation on the specific detachable connection method. Since the tray 3a can be fixed to a certain extent when the teeth bite the tray 3a, it is only necessary to ensure that the connection can transmit vibration well.

[0109] The problem mentioned in the first embodiment that the tray 3a in the middle is difficult to cover the first premolar is well solved in this embodiment. Fig.12 As shown, since there is no need to set the extension part 3a2 on the trays 3a located on the left and right wings, it can be ensured that the tray 3a located in the middle has enough space to set the alveolar part 3a1 thereon. Therefore, the tray 3a located in the middle can extend the coverage range to the first premolar, and even cover the position of the second premolar as needed, so it can have a wider clinical application space.

[0110] In this embodiment, the manufactured products can also be equipped with multiple trays 3a of different specifications and coverage areas located in the middle to meet the diverse needs of patients. The number of trays 3a located on the left and right wings can be increased and the trays 3a on the left and right wings can be connected in series in sequence, thereby saving materials and achieving better adaptability.

[0111] In summary, when the trays 3a on the left and right wings are connected to the tray 3a in the middle, the tray 3a in the middle can occupy a larger coverage area, so it can have better adaptability.

[0112] Implementation Method 6

[0113] The sixth embodiment of the present invention provides a tooth correction auxiliary device. The fifth embodiment is different from the first to fifth embodiments. The main difference is that in the first five embodiments of the present invention, the vibration generated by the vibration device 2 is transmitted to the connecting part 4 through the shell 1, and then transmitted to the dental tray assembly 3; while in the fifth embodiment of the present invention, the vibration device 2 is directly connected to the connecting part 4.

[0114] Specifically, in this embodiment, see Fig.13As shown, the vibration device 2 also includes a motor 2a and an eccentric wheel 2b connected in series to the motor 2a; the motor 2a drives the eccentric wheel 2b to rotate and generate vibration;

[0115] One end of the connecting member 4 located outside the housing 1 is sleeved on the eccentric wheel 2b;

[0116] The eccentric wheel 2 b drives the connecting member 4 to vibrate and transmits the vibration to the dental tray assembly 3 .

[0117] Since the main principle of the vibration device 2 to generate vibration is that the motor 2a drives the eccentric wheel 2b connected in series to the motor 2a to rotate and generate vibration, the frequency of the vibration can be adjusted by adjusting the rotation frequency of the motor 2a to achieve the purpose of controlling the vibration frequency. The end of the connecting member 4 located outside the housing 1 is arranged on the eccentric wheel 2b, and the vibration of the eccentric wheel 2b can be directly transmitted to the connecting member 4, thereby improving the efficiency of vibration transmission and reducing the requirements for the motor 2a and the housing.

[0118] It is worth mentioning that, for the present invention, reducing the demand for the motor 2a and the housing is of great significance. This is because patients usually need to use the orthodontic auxiliary device of the present invention continuously for 10 minutes to half an hour every day. During this period, the orthodontic auxiliary device needs to be fixed in the air in front of the patient's chin. Therefore, a lighter and smaller orthodontic auxiliary device is more easily accepted by patients. In particular, in the present invention, compared with other orthodontic auxiliary devices in the prior art, the tray 3a included in the tray assembly 3 that connects the patient's mouth and the orthodontic auxiliary device is narrower in thickness and more prone to bending and damage.

[0119] Therefore, in the present invention, the vibration of the eccentric wheel 2b is directly transmitted to the connecting member 4, which reduces the power requirement of the motor 2a, and a lighter motor 2a can be used at the same cost, and at the same time reduces the strength requirement of the housing, and a lighter and thinner housing can be used at the same cost. This has important improvement significance.

[0120] See also Fig.14 As shown, in order to further reduce the strength requirement of the connecting member 4, in the present invention, a damping ring 6 can be provided between the connecting member 4 and the eccentric wheel 2b. The damping ring 6 can be made of elastic material, which can extend the service life of the connecting member 4.
