Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of orthodontics, more specifically, to an orthodontic extraoral traction device. BACKGROUND
[0002] For patients with early skeletal class III malocclusion, anterior traction is the preferred method of orthodontic treatment. This method mainly relies on the growth potential of the patient, and applies orthopedic force to the maxilla to promote its development and solve the problem of maxillary dysplasia. In this way, the growth of the maxilla can be effectively promoted, thereby improving or alleviating the severity of class III malocclusion. The commonly used mask type extraoral traction device on the market is relatively large in size, and usually requires the use of bolts to clamp the upper and lower clamping blocks, which often results in excessive weight of the device, reducing the comfort level when worn, and easily causing significant weight fatigue to the user.
[0003] For example, application No. 202011138886.8 discloses an orthodontic traction device, which comprises a traction mounting seat, an upper clamping block, a lower clamping block, a locking bolt and an arch wire. The traction mounting seat is an arc-shaped traction mounting seat fixed on the teeth, and a limiting groove is provided in the middle of the front side of the traction mounting seat. An L-shaped upper clamping groove and an L-shaped lower clamping groove are provided in the limiting groove, and the L-shaped upper clamping groove and the L-shaped lower clamping groove are symmetrically arranged. An outer arc groove is provided on the side surface of the traction mounting seat, and two arch wire limiting holes are provided on both sides of the traction mounting seat. The upper clamping block is provided at the top of the limiting groove, and a positioning block is fixed to the bottom of the upper clamping block.
[0004] Although the above-mentioned orthodontic traction device can change the bone to treat the effect, but its traction mounting seat is usually a standard part, which leads to the fact that their comfort and fit are often unsatisfactory. Patients may therefore develop resistance to wearing the device, which can cause uncertainty in the treatment time and have a significant impact on the planning and execution of the orthodontic treatment plan.

[0038] Please refer to Figure 1 The embodiment provides an orthodontic extraoral traction device, which comprises a support mask 100 and a traction hook 400. The support mask 100 is used for being connected to a patient's face in a fit manner. The support mask 100 has an oral opening 110. The traction hook 400 is arranged on the support mask 100 and located at two sides of the oral opening 110. The traction hook 400 is used for mounting a traction rubber band.
[0039] In the embodiment, the support mask 100 can be connected to the patient's face in a fit manner. For example, the support mask 100 can be customized according to the face structure 500 of each patient, so that the fit degree and comfort of the orthodontic extraoral traction device are improved. Compared with the standard accessories of the common extraoral traction device in the prior art, the orthodontic extraoral traction device can provide a more fit and comfortable treatment experience for the patient, thereby improving the compliance and cooperation of the patient in the treatment process.
[0040] Therefore, the embodiment improves the comfort of the wearer by connecting the support mask 100 to the patient in a fit manner, provides a more comfortable and healthy treatment experience for the patient, and can improve the compliance and cooperation of the patient in the treatment process.
[0041] Specifically, please refer to Figure 1 and Figure 2 In the embodiment, the support mask 100 comprises a base body 200 and two vertical traction arms 300. The two vertical traction arms 300 are arranged on the base body 200. The two vertical traction arms 300 are located at two sides of the oral opening 110. The vertical traction arms 300 are used for mounting the traction hook 400.
[0042] In the embodiment, the traction hook 400 is mounted on the two vertical traction arms 300. One vertical traction arm 300 is located at the left side of the oral opening 110, and the other vertical traction arm 300 is located at the right side of the oral opening 110.
[0043] In the prior art, when using a traditional extraoral traction device, the clinician is prone to incorrectly apply the force line to the horizontal plane of the bracket, which is approximately parallel to the occlusal plane, but since the force does not pass through the center of resistance, the traction hook 400 will generate a moment, often causing the maxillary dental arch to rotate counterclockwise and the anterior teeth to open, etc. In the present embodiment, the support mask 100 can be made by 3D printing, and the positioning and orientation design of the vertical traction arm 300 and the traction hook 400 can be accurately planned according to the matching results of the three-dimensional facial data and lateral image data of the individual patient by using computer-aided design software, to determine the position and direction of the vertical traction arm 300 and the traction hook 400, and thus, compared with the traditional extraoral traction device, the present embodiment can avoid applying the force line to the horizontal plane of the bracket, which is helpful to accurately plan the traction direction of the elastic traction rubber band and the distance between the intraoral force point and the extraoral force point on the extraoral traction device. These factors collectively help the doctor to develop an efficient, accurate, and personalized orthodontic treatment plan, effectively reducing problems such as maxillary anterior rotation caused by improper traction direction, thereby reducing the risk of prolonged treatment period, providing patients with a more reliable and reassuring treatment experience, and improving treatment efficiency.
[0044] Specifically, please refer to Figure 1 , at least two traction hooks 400 are provided on one vertical traction arm 300; the traction hook 400 comprises a traction cross arm 410 and a vertical hook portion 420, the traction cross arm 410 is formed by extending horizontally outward from the vertical traction arm 300, and the vertical hook portion 420 is formed by extending downward from the traction cross arm 410.
[0045] In the present embodiment, at least two traction hooks 400 are provided on one vertical traction arm 300, for example, two traction hooks 400 are provided on one vertical traction arm 300, wherein the traction hook 400 comprises a traction cross arm 410 and a vertical hook portion 420, which is equivalent to two downward traction hooks 400 provided on one vertical traction arm 300, and the position and direction of the vertical traction arm 300 and the traction hook 400 are helpful to accurately plan the traction direction of the elastic traction rubber band and the distance between the intraoral force point and the extraoral force point on the orthodontic extraoral traction device. These factors collectively help the doctor to develop an efficient, accurate, and personalized orthodontic treatment plan, effectively reducing problems such as maxillary anterior rotation caused by improper traction direction, thereby reducing the risk of prolonged treatment period, providing patients with a more reliable and reassuring treatment experience, and improving treatment efficiency.
[0046] Specifically, please refer to Figure 1The support mask 100 can further comprise a forehead pad portion 210, a cheek rest portion 220, a nose bridge portion 230, and a chin rest portion 240. The forehead pad portion 210 is arranged on the base body 200 and is used to be connected to the forehead of the patient. The cheek rest portion 220 is arranged on the base body 200 and is used to be connected to the cheekbones of the patient. The nose bridge portion 230 is arranged on the base body 200 and is used to be connected to the nose bridge of the patient. The chin rest portion 240 is arranged on the base body 200 and is used to be connected to the chin of the patient.
[0047] In the embodiment, the support mask 100 can rely on the key structures of the face such as the forehead, the nose bridge, the cheekbones, and the chin to provide necessary support areas for the orthodontic extraoral traction device. Meanwhile, the forehead pad portion 210, the cheek rest portion 220, the nose bridge portion 230, and the chin rest portion 240 can be connected to the forehead, the cheekbones, the nose bridge, and the chin of the patient, thereby improving the fitting degree and the comfort of the wearer and providing the patient with a more comfortable treatment experience.
[0048] Specifically, referring to Figure 1 The nose bridge portion 230 and the chin rest portion 240 are connected by two vertical traction arms 300.
[0049] In the embodiment, the support mask 100 and the traction hooks 400 can be integrally formed. That is, the base body 200, the two vertical traction arms 300, the forehead pad portion 210, the cheek rest portion 220, the nose bridge portion 230, and the chin rest portion 240 are integrally formed. The upper end of the nose bridge portion 230 is connected to the lower side of the forehead pad portion 210. The lower end of the nose bridge portion 230 is connected to the upper side of the cheek rest portion 220. The lower left side of the cheek rest portion 220 is connected to one vertical traction arm 300. The lower right side of the cheek rest portion 220 is connected to the other vertical traction arm 300. Each vertical traction arm 300 is provided with two downward traction hooks 400.
[0050] Compared with the traditional extraoral traction device, the embodiment can omit the step of fastening the upper and lower clamping blocks by bolts, thereby optimizing the process of wearing the traction device by the patient during orthodontic treatment. In addition, it also reduces the volume of the front traction bracket and effectively prevents the discomfort caused by the extrusion of the two side components on the patient's face. Since the support mask 100 in the embodiment can be customized according to the facial structure 500 of the patient, the comfort and the appearance aesthetics of the patient during wearing are improved to a certain extent. The support mask 100 can be made of resin material. The lightweight property of the resin material significantly reduces the weight, effectively reduces the burden and fatigue of the wearer, and provides the patient with a more comfortable and healthy orthodontic treatment experience, thereby improving the compliance and cooperation of the patient during the treatment process.
[0051] Optionally, the thickness of the support mask 100 is 3-5 mm.
[0052] For example, the support mask 100 can be made of a resin material, and the thickness of the support mask 100 is 3-5 mm. The support mask 100 is light in weight, thin in thickness, small in space occupation, and beautiful in appearance, effectively reducing the burden and fatigue of the wearer, providing a more comfortable and healthy orthodontic treatment experience for the patient, and thus improving the compliance and cooperation of the patient during the treatment process. It should be understood that the thickness of the support mask 100 is not limited to the above-mentioned 3-5 mm, and the thickness of the support mask 100 can also be other cases, which are not limited here.
[0053] Preferably, the thickness of the support mask 100 is 4 mm, which is thin in thickness, small in space occupation, and beautiful in appearance, effectively reducing the burden and fatigue of the wearer, providing a more comfortable and healthy orthodontic treatment experience for the patient, and thus improving the compliance and cooperation of the patient during the treatment process.
[0054] Specifically, in the present embodiment, the support mask 100 can include a resin 3D printed structure, that is, the support mask 100 can be made by 3D printing. For example, the 3D facial model data of the patient can be obtained in advance according to the patient's face, and then the support mask 100 is 3D printed according to the 3D facial model data. In this way, the shape and size of the support mask 100 can be customized according to the facial anatomical structure characteristics of each patient, thereby improving the fit and comfort of the traction device. Compared with the standard accessories of the common mouth external traction device on the market, the support mask 100 provided in the present embodiment can provide a more fitted and comfortable treatment experience for the patient.
[0055] In addition, the present embodiment can also adjust the coverage range of the support mask 100 according to the case of each patient. For example, for patients with facial deformities or patients with prominent chins, the area that makes the patient uncomfortable can be avoided, or the width of the lower jaw support part 240 in the coverage range of the support mask 100 can be appropriately increased to distribute the force laterally to the chin. At the same time, the present embodiment can match the 3D facial model data of the patient with the support mask 100 according to the computer design software, and determine the application point of the support mask 100 and the direction of the traction force on the computer according to the specific circumstances of each patient. This includes the position and direction of the vertical traction arm 300 and the traction hook 400, which helps to accurately plan the traction direction of the elastic traction rubber band, as well as the distance between the intraoral force point and the extraoral force point on the traction device.
[0056] The support mask 100 in the embodiment is printed by 3D printing technology, and the designed orthodontic extraoral traction device can be printed out by using resin material, so that the structural integrity is guaranteed. The resin 3D printing structure reduces the volume of the front traction bracket, effectively prevents the discomfort caused by the extrusion of the two side components on the patient's face, and the resin 3D printing structure is customized according to the patient's facial structure 500, so that the comfort and appearance aesthetics of the patient when wearing are improved to a certain extent. Due to the lightness of the resin material, the weight of the resin 3D printing structure is significantly reduced, effectively reducing the burden and fatigue of the wearer, providing a more comfortable and healthy orthodontic treatment experience for the patient, and thus improving the compliance and cooperation of the patient during the treatment process.
[0057] In summary, the application discloses an orthodontic extraoral traction device, which comprises a support mask and a traction hook. The support mask is used to be connected with the patient's face, and has an oral opening. The traction hook is arranged on the support mask and located on both sides of the oral opening, and is used to install a traction rubber band. The support mask is connected with the patient, which improves the comfort of the wearer and provides a more comfortable and healthy treatment experience for the patient, and can improve the compliance and cooperation of the patient during the treatment process.
[0058] The above is only a preferred embodiment of the application, and is not used to limit the application. Any modification, equivalent replacement and improvement made within the spirit and principle of the application should be included in the protection scope of the application.
