Description

Technical Field

[0001] This application relates to the technical field of dental orthodontic instruments, and particularly to an adjustable-angle orthodontic bracket and orthodontic method. Background Technology

[0002] Orthodontic treatment is a highly specialized branch of dentistry, primarily addressing the correction of dental, jaw, and facial deformities. It involves gradually restoring normal occlusal function by fixing orthodontic appliances inside the mouth. Orthodontic brackets are a crucial component of these appliances, mainly bonded to the anterior teeth, canines, and premolars. During orthodontic treatment, the brackets are positioned and directly bonded to the surface of each tooth by centering them on the clinical crown or using techniques that maintain distance from the incisor margins. Once the brackets are in place, the archwire is inserted and securely attached to each bracket with elastic bands. The archwire applies various types of corrective forces to the teeth through the brackets. The main function of the orthodontic brackets, as precision-machined devices, is to fix the archwire on the tooth surface, allowing it to function more effectively and transmit corrective forces to control the three-dimensional movement of the teeth. The restorative force provided by the archwire, restoring the initial arch shape, becomes the corrective force, moving the teeth to the proper alignment and forcing them into the correct position, thus achieving the goal of orthodontic treatment.

[0003] Currently, the base structure of commercially available metal braces mainly consists of a welded metal mesh base, a molded base, or a machined base. The base is typically curved and designed to conform to the tooth surface to transmit corrective force. However, the torque angle, rotation angle, and base thickness of commercially available orthodontic brackets are fixed, which cannot meet the actual dentition data requirements of many individual patients. In clinical practice, differences in tooth type and surface characteristics lead to poor conformation between the bracket base and the tooth surface. A fixed curved base cannot match all tooth surfaces, therefore, the corrective force cannot be effectively transmitted to the teeth through the bracket, failing to guarantee ideal orthodontic precision and consistent results during orthodontic treatment. In the later stages of treatment, many cases require fine-tuning, meaning that the original bracket dimensions may no longer meet the actual dentition correction goals.

[0004] Based on the above issues, it is necessary to develop an orthodontic bracket that can be adapted to different individual dentition data, with adjustable torque in the gingival-occlusal direction, adjustable rotation in the mesiodistal direction, or adjustable base thickness in the labiolingual direction, so as to meet the needs of individual dentition data and achieve good orthodontic results. Summary of the Invention

[0005] To address the aforementioned technical issues, this application provides an adjustable-angle orthodontic bracket that allows for adjustment of torque in the gingival-maxillary direction, rotation in the mesiodistal direction, or bracket thickness in the labiolingual direction, thereby improving orthodontic accuracy and achieving better treatment results.

[0006] In a first aspect, this application provides an adjustable-angle orthodontic bracket, employing the following technical solution: an adjustable-angle bracket, comprising a main body and a support member; the main body includes a base and a groove, the groove being provided with a bracket groove, the base being provided with a bottom surface for fixed connection with the tooth surface; the support member is connected to the base and extends away from the bracket groove; wherein, the support member is provided with a structure for adjusting the extension length of the support member, and the height of the support member protruding from the bottom surface is changed by adjusting the structure.

[0007] By adopting the above technical solution, the support member is used to abut against the tooth surface to apply force to the tooth, adjust the torque in the gingival-occlusal direction and the rotation in the mesiodistal direction of the tooth to be corrected. The support member has an adjustable length structure to adjust its length. By adjusting the structure, the height of the support member protruding from the bottom surface is changed, ensuring good contact between the support member and different positions on the surface of the tooth to be corrected, and realizing the effective transmission of orthodontic force to the tooth. At least two supports are provided, with four being optimal. The four supports abut against the distal end of the tooth for small-area contact, which can adapt to various uneven tooth surface shapes. The bracket, through the four supports, can make good contact with the tooth surface, ensuring the effectiveness of the orthodontic force transmitted by the bracket to the tooth.

[0008] Based on the first aspect, a further embodiment is that the support extends along the extension direction of the bracket groove to adjust the rotation of the teeth in the mesiodistal direction.

[0009] By adopting the above technical solution, the production and processing of brackets is simple and convenient. The support component and the main body of the bracket can be integrally formed or fixed together by welding, gluing, threading, or riveting. During use, the support component can be bent towards the bottom surface using tools to make it higher than the bottom surface, thus achieving contact with the tooth surface. By controlling the bending position of the support component, the distance between the support component and the bottom surface of the base can be controlled, thereby improving the effective contact between the bracket and the tooth surface. Simultaneously, the extension length of the support component can be adjusted using a structure on the support component. By combining the control of the bending position and the adjustment of the extension length, the length of the support component can be more precisely adjusted, further improving the effective fit between the bracket and the tooth surface.

[0010] Based on the first aspect, a further embodiment is that the support extends in a direction perpendicular to the extension direction of the bracket groove, for adjusting the gingival occlusal torque.

[0011] By adopting the above technical solution, the production and processing of brackets is simple and convenient. The support component and the main body of the bracket can be integrally formed or fixed together by welding, gluing, threading, or riveting. During use, the support component can be bent from another angle towards the bottom surface using tools, making it higher than the bottom surface to abut against the tooth surface. By controlling the bending position of the support component, the distance the support component is higher than the bottom surface can be controlled, thereby improving the fit between the bracket and the tooth surface. Simultaneously, the extension length of the support component can be adjusted using a structure on the support component. By combining the control of the bending position and the adjustment of the extension length, the length of the support component can be more precisely adjusted, further improving the effective fit between the bracket and the tooth surface.

[0012] Based on the first aspect, a further solution is that the support extends along the base extension direction to adjust the thickness of the bracket lip towards the bottom.

[0013] By adopting the above technical solution, the support extends in a direction perpendicular to the extension direction of the bracket groove and along the extension direction of the base. The support can be integrally formed with the main body or processed separately and then fixed into one piece, which facilitates processing and forming. The support extends along the extension direction of the base to adjust the thickness of the bracket lip and tongue towards the base. In addition, during clinical orthodontic treatment, each support can be bent at an appropriate position according to the specific tooth surface shape to be corrected to ensure that all supports are in full contact with the tooth surface, thereby better transmitting the orthodontic force.

[0014] Based on the first aspect, a further technical solution is that the support protrudes from the bottom surface and extends away from the bottom surface.

[0015] By adopting the above technical solution, in clinical applications, the length of each support protruding from the bottom surface can be adjusted according to different tooth shapes and orthodontic plans to ensure reliable contact between the bracket and the tooth surface through the support. When adjusting the length of the support protruding from the bottom surface, the height of the support protruding from the bottom surface is changed directly by adjusting the extension length of the support to adapt to the shape of the tooth surface to be treated, thereby achieving good contact between the bracket and the tooth surface.

[0016] Based on the first aspect, a further solution is that the support member is threadedly connected to the base.

[0017] By adopting the above technical solution, the height of the support protruding from the base can be adjusted by rotating the support to adapt to different tooth surface shapes, ensuring a good fit between the bracket and the tooth surface. Through threaded connection, the height of the support protruding from the base can be continuously varied, resulting in higher adjustment precision, more stable fit between the bracket and the tooth surface, and more effective transmission of orthodontic force.

[0018] Based on the first aspect, a further technical solution is provided, wherein a locking element is provided between the support member and the base to prevent the support member from becoming loose.

[0019] By adopting the above technical solution, it is possible to prevent the support from loosening during the orthodontic process and ensure the stability of the relative position of the support and the main body to achieve the expected orthodontic effect.

[0020] Based on the first aspect, a further technical solution is that the support member is provided with a stress concentration structure.

[0021] By adopting the above technical solution, an external force can be applied to the stress concentration structure to break the support from the stress concentration structure, thereby adjusting the height of the support protruding from the bottom surface and ensuring a good fit between the bracket and the tooth surface. The stress concentration structure of the support is a V-shaped notch, which facilitates bending it into a right angle or breaking it in clinical practice. It also serves as a fixed distance marker on the support, which helps to directly check or calculate the corresponding torque, rotation angle, or bottom thickness in clinical practice.

[0022] Secondly, this application provides an orthodontic method, including the orthodontic brackets described above. The method includes the following steps: CT data acquisition and dental model making: taking CT images of the patient's oral cavity and creating a three-dimensional digital model of the dental model; three-dimensional reconstruction of oral tissue model: reconstructing the patient's oral cavity model based on CT data using three-dimensional reconstruction software; obtaining a composite model: overlapping the model with the CT-reconstructed model to obtain a composite model including teeth, alveolar bone, and gingival surface; obtaining an orthodontic plan: on the composite model, based on the patient's tooth misalignment, formulating the steps for tooth movement to obtain an orthodontic plan, calculating key parameters, including the amount of tooth movement, the required orthodontic force and torque, and the method of force application, and determining the target dentition after treatment; determining brackets: selecting orthodontic brackets for each tooth according to the target dentition and determining the position of the orthodontic brackets on the teeth; adjusting brackets: rotating the support member according to the position of each orthodontic bracket on the tooth to obtain a suitable support height for the support member protruding from the bottom surface; fixing brackets: abutting the bracket support member against the tooth surface and fixing the orthodontic bracket to the tooth.

[0023] The above technical solution involves obtaining a composite model through data acquisition and three-dimensional reconstruction of oral tissue. An orthodontic plan is then developed based on this composite model. The orthodontic plan determines the bracket's position on the tooth surface, and the height of the support component protruding from the bottom surface is adjusted by rotating it according to the tooth shape and the amount of tooth movement required by the orthodontic plan. When adjusting the support height, the bracket is first placed on the tooth surface, and the support component is rotated until it abuts against the tooth surface. The height of each support component is continuously adjusted to obtain the optimal support solution. This solution ensures the standardization of brackets while enabling customized bracket sizes for different tooth shapes, satisfying both mass production of brackets and the universality of various orthodontic plans.

[0024] Thirdly, the present invention provides an orthodontic method, including the orthodontic brackets described above. The method includes the following steps: CT data acquisition and dental model fabrication: capturing CT images of the patient's oral cavity and creating a three-dimensional digital model of the dental model; three-dimensional reconstruction of the oral tissue model: reconstructing the patient's oral cavity model based on the CT data using three-dimensional reconstruction software; obtaining a composite model: overlapping this model with the CT-reconstructed model to obtain a composite model including teeth, alveolar bone, and gingival surface; obtaining an orthodontic plan: based on the composite model and the patient's tooth misalignment, formulating a tooth movement plan. The process involves several steps: obtaining an orthodontic plan, calculating key parameters including tooth movement, required orthodontic force and torque, and the method of force application, and determining the target dentition after treatment; selecting brackets: choosing orthodontic brackets for each tooth based on the target dentition and determining the bracket's position on the tooth; adjusting brackets: breaking the support at stress concentration points according to the position of each bracket on the tooth to obtain a suitable support angle between the bottom surface and the tooth; processing the support: smoothing the broken part of the support; fixing the bracket: abutting the bracket support against the tooth surface and fixing the orthodontic bracket to the tooth. Through the above technical solution, a composite model is obtained through data acquisition and three-dimensional reconstruction of oral tissue. An orthodontic plan is then developed based on this composite model. The orthodontic plan determines the position of the orthodontic brackets on the tooth surface, and the support is broken at stress concentration points according to the tooth surface shape and the tooth movement amount in the orthodontic plan to obtain a suitable support angle between the bottom surface and the tooth. The proposed solution ensures the standardization of brackets while enabling customized bracket sizes for different tooth shapes, thus satisfying both the need for mass production of brackets and the universality of different orthodontic solutions.

[0025] In summary, this application has at least one of the following beneficial technical effects:

[0026] 1. The adjustable-angle orthodontic bracket of this application has four height-adjustable support members on its base. In clinical application, if it is necessary to adjust the torque in the gingival direction or the rotation in the mesiodistal direction, two support members on the corresponding side of the base plate can be removed for adjustment. By adjusting the length of the support members that abut against the teeth, good contact between the support members and the surface of the teeth to be corrected at different positions is ensured, so as to effectively transmit the orthodontic force to the teeth and thus meet the needs of personalized treatment.

[0027] 2. The adjustable angle orthodontic bracket of this application is simple and convenient to manufacture and process. By adjusting the bending position of multiple support members and / or breaking different stress concentration structures, the distance of the support members above the bottom surface of the base can be controlled, thereby improving the effective contact between the bracket and the tooth surface.

[0028] 3. The adjustable angle orthodontic bracket of this application directly changes the height of the support protruding from the bottom surface through multiple stress concentration structures to adapt to the shape of the tooth surface to be corrected, so as to achieve good contact between the bracket and the tooth surface.

[0029] 4. The adjustable angle orthodontic bracket of this application is connected to the base by multiple support members through threads. The height of the support members protruding from the bottom surface of the base can be continuously changed, resulting in higher adjustment accuracy, more stable fit between the bracket and the tooth surface, and more effective transmission of orthodontic force.

[0030] 5. The adjustable angle orthodontic bracket of this application, through the self-locking mechanism, can prevent the support from loosening during the orthodontic process, and ensure the stability of the relative position of the support and the main body to achieve the expected orthodontic effect.

[0031] 6. The orthodontic method of this application can ensure the standardization of brackets while realizing customized bracket sizes for different tooth shapes, which can meet both the needs of mass production of brackets and the universality of different orthodontic schemes.

[0052] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0053] Example 1:

[0054] Please see Figure 1 As shown, an adjustable-angle orthodontic bracket 100 structure is disclosed. The orthodontic bracket 100 includes an arc-shaped base 1 and four support members 2 integrally formed with the base 1 and extending outward. A groove 5 is fixedly connected to the base 1. The upper part of the groove 5 is provided with a working wing 51. The surface of the base 1 facing the working wing 51 is a lip side, and the bottom surface of the base 1 away from the working wing 51 is a tongue side. The support member 2 is provided with a stress concentration structure. In this embodiment, the stress concentration structure is a notch 21 opened on opposite sides of the support member 2. A groove 4 for passing the archwire is provided between the grooves 5. The grooves 5 are provided with working wings 51 for fixing the archwire by wrapping ligation equipment. The four support members 2 include two pairs extending in a vertical direction. One pair of support members 2 extends outward along the extension line of the groove 4, and the other pair of support members 2 extends outward along the perpendicular line of the groove extension line. The bottom surface 11 of the groove 4 can be a plane or an arc-shaped surface similar to the base 1. The groove 5 is also equipped with a traction hook 3, which is used to move the teeth toward the target direction using tools.

[0055] Example 2:

[0056] Please see Figure 2 As shown, unlike Embodiment 1, the base 1 is planar, and all four support members 2 extend outwards perpendicularly to the extension line of the groove 4, with two support members 2 on the same side spaced apart. In another modified embodiment, the four support members 2 extend outwards along the extension line of the groove 4. The side surface of the groove 4 is perpendicular to the upper surface of the base 1, and the bottom surface 11 of the groove 4 is parallel to the upper surface of the base 1.

[0057] Please see Figure 3 and Figure 4 As shown, this is the structural state of tooth 6 during orthodontic treatment in Embodiment 2. Before orthodontic treatment of tooth 6, an orthodontic plan is developed for the patient's tooth 6. Then, according to the orthodontic plan, the four support members 2 are bent accordingly, with the bending direction facing away from the working wing 51 towards the lingual side and perpendicular to the base 1. Depending on different tooth surface shapes and orthodontic plans, the four support legs can be combined in various ways, for example... Figure 3 The two supports 2, extending perpendicularly to the groove 4, are bent to adjust the gingival-occlusal torque of tooth 6, with an adjustment range of 5° to 14°; or as shown... Figure 4 The two supports 2 on the same side along the extension line of the groove 4 are bent to adjust the mesiodistal rotation of the tooth 6, with the rotation adjustment range being 7° to 20°; two diagonally opposite supports 2 can also be bent, or three or four supports 2 can be bent to adjust and correct the tooth 6 in combination.

[0058] To achieve the desired orthodontic effect, it is necessary to control the height of the support member 2 protruding from the bottom surface 11 of the base 1. The height of the support member 2 protruding from the bottom surface 11 can be controlled by different bending positions and angles of the support member 2, and can also be finely adjusted by breaking the notch 21 on the support member 2. The height of the support member 2 protruding from the bottom surface 11 should not exceed 1 mm.

[0059] Example 3:

[0060] Please see Figure 5 and Figure 6 As shown, unlike embodiments one and two, in this embodiment, the support member 2 is fixed to the bottom surface 11 of the base 1 and extends towards the tongue side. The support member 2 protrudes from the bottom surface 11 by no more than 1 mm. The stress concentration structure of the support member 2 is a tower-shaped structure composed of three cylindrical sections, the height of which can be the same or different. When adjusting the height of the support member 2, the root of the corresponding cylindrical section of the support member 2 can be broken off. The support member 2 can be integrally formed with the base 1 or fixed to the base 1 by welding or gluing. The material of the support member 2 can be stainless steel or ceramic. The bottom surface 11 of the base 1 is patterned to make the bottom surface 11 more firmly bonded to the tooth 6. The side of the groove 4 is perpendicular to the upper surface of the base 1, and the bottom surface 11 of the groove 4 is parallel to the upper surface of the base 1.

[0061] Please see Figure 7 The diagram shows the orthodontic bracket 100 fixed to the tooth 6. The orthodontic bracket 100 abuts against the surface of the tooth 6 via four support members 2, and is fixed to the surface of the tooth 6 by an adhesive between the bottom surface 11 and the tooth surface. By adjusting the height of the support members 2 to accommodate the tooth surface of the tooth 6 and the torque or rotation of the orthodontic treatment plan, the orthodontic bracket 100 can maintain good contact with the surface of the tooth 6 to transmit corrective force and ensure the orthodontic effect.

[0062] Example 4:

[0063] Please see Figure 8 and Figure 9As shown, unlike Embodiment 3, the support foot in this embodiment is a rectangular prism, and the stress concentration structure of the support foot is a groove notch 21. The bottom surface 11 and side surface of the groove 4 are both inclined at an angle to the upper surface of the base 1. The purpose of the inclined groove 4 is to prevent the archwire from easily coming out of the groove 4 after the orthodontic bracket 100 is fixed to the tooth 6 after the height of the support 2 is adjusted. After the inclination angle of the groove 4 is preset in advance, the inclination of the groove 4 relative to the surface of the tooth 6 is smaller after the support 2 is shortened, and the probability of the archwire coming out of the groove 4 is reduced. When adjusting the support 2, the corresponding support 2 can be cut off at the notch 21 as needed. The bottom of the support 2 is also provided with a textured surface 22 for fixing the glue and preventing slippage.

[0064] Example 5:

[0065] Please see Figure 10 As shown, the difference from Embodiment 4 is that the support member 2 in this embodiment is a cylinder, and the end of the support member 2 is provided with a spherical bottom 23, and the stress concentration structure is an annular groove.

[0066] Example 6:

[0067] Please see Figure 11 As shown, the difference from Embodiment 4 is that the side of the groove 4 in this embodiment is perpendicular to the upper surface of the base 1, and the bottom surface 11 of the groove 4 is parallel to the upper surface of the base 1.

[0068] Example 7:

[0069] Please see Figure 12 and Figure 13 As shown, unlike the six embodiments above, in this embodiment, the support member 2 is threadedly connected to the base 1. The height of the support member 2 protruding from the bottom surface 11 can be adjusted by rotating it. The support member 2 can be a slotted screw, a Phillips head screw, or a hex socket screw. The base 1 has a threaded hole that mates with the support member 2. A locking element to prevent the support member 2 from loosening is provided between the support member 2 and the base 1; in this embodiment, the locking element is a spring washer 24. After the height of the support member 2 is adjusted, it can be fixed to the base 1 as a single unit by adhesive bonding or laser welding. The height dimension of this embodiment can be continuously adjusted with higher precision.

[0070] Please see Figure 14 The diagram shown illustrates the fixed state of the orthodontic bracket 100 and the tooth 6 in this embodiment. In this embodiment, the height of the support member 2 can be intuitively adjusted on the surface of the tooth 6 requiring correction, making adjustment simpler, more convenient, more precise, and resulting in better correction.
