Abstract
Description
Technical Field
[0001] The present application relates to the field of oral orthodontic devices, and in particular to a closed deep overbite appliance. Background Art
[0002] As children grow and develop, they often develop malocclusions, such as misaligned teeth and a mismatched relationship between teeth and bones, due to a combination of genetic factors and unhealthy lifestyle habits. These problems not only affect facial appearance but can also lead to conditions such as dental caries, periodontal disease, and temporomandibular joint disease.
[0003] A closed overbite is when the upper front teeth tilt inward (ie, tilt toward the tongue) and completely cover the lower teeth (eg Figure 4 As shown, the lingual tilt of the upper front teeth e1 means that the positive direction of the tooth axis f1 of the upper front teeth e1 relative to the normal vector o1 pointing downward to the jaw plane F is deflected toward the lingual side. The positive direction of the tooth axis f1 of the upper front teeth e1 is the direction from the root of the upper front teeth e1 to the crown of the upper front teeth e1 along the tooth axis f1), and it firmly holds the lower teeth. In severe cases, it will also cause the lower front teeth to tilt inward (i.e. tilt toward the lingual side, as shown in the figure). Figure 4 As shown, lingual inclination of the lower anterior tooth e2 means that the positive direction of the tooth axis f2 of the lower anterior tooth e2 is deflected lingually relative to the upward normal vector o2 of the jaw plane F (the positive direction of the tooth axis f2 of the lower anterior tooth e2 is the direction along the tooth axis f2 from the root of the lower anterior tooth e2 to the crown of the lower anterior tooth e2). This not only affects facial aesthetics but also reduces chewing function, easily restricts mandibular development, and can cause occlusal trauma and temporomandibular joint disorders. Therefore, orthodontic treatment of closed deep overbite is essential.
[0004] The basic principle of orthodontics is to apply appropriate corrective force to the teeth, alveolar bone, periodontal tissues, jawbone, and temporomandibular joint, thereby inducing tissue remodeling and ultimately achieving tooth movement. Currently, a wide variety of medical devices are used in orthodontics, primarily including removable appliances, bracket appliances, and bite-inducing appliances. Occlusion-inducing appliances are increasingly used in pediatric orthodontics due to their ease of wear, comfort, and ease of cleaning.
[0005] However, existing bite-inducing appliances remain inadequate for improving children's deep overbites. These appliances typically adopt a standard, uniform design and cannot be individually adjusted for each child's specific situation. Furthermore, existing appliances lack precise correction force on the upper and lower front teeth, making it difficult to effectively control the direction and speed of tooth movement. These issues lead to suboptimal treatment results, prolonged treatment cycles, and may even cause other oral problems.
[0006] In view of the above problems, the existing technology is in urgent need of improvement. Utility Model Content
[0007] The purpose of the present application is to provide a closed deep bite correction device that can effectively correct the problem of closed deep bite.
[0008] The present application provides a closed deep overbite orthodontic appliance, which is an occlusal induction appliance, comprising an appliance body having a jaw pad, an upper receiving groove and a lower receiving groove, wherein the upper receiving groove is used to accommodate the patient's upper dentition, and the lower receiving groove is used to accommodate the patient's lower dentition; the thickness of the jaw pad in the anterior tooth area is greater than the patient's intermandibular space; the anterior tooth area of the upper receiving groove is provided with an upper correction groove, and the posterior tooth area of the upper receiving groove and the posterior tooth area of the lower receiving groove are both provided with avoidance grooves; the inclination angle of the upper correction groove toward the lingual side is smaller than the inclination angle of the patient's upper anterior teeth toward the lingual side, and the avoidance groove is used to provide extension space for the patient's posterior teeth.
[0009] The principle of this design is to open the patient's jaws and bite by making the thickness of the jaw pad in the front teeth area larger than the resting jaw space to provide space for the teeth to move. At the same time, the difference in the inclination angle of the correction groove is used to apply a continuous corrective force. The effect of this force is slow but continuous, which can gradually change the inclination angle of the teeth. The avoidance groove provides elongation space for the posterior teeth to elongate, so that the upper and lower front teeth are gradually separated in the upper and lower directions, thereby effectively correcting the problem of closed deep overbite.
[0010] Preferably, the inclination angle of the upper correction groove toward the lingual side is smaller than the inclination angle of the patient's upper front teeth toward the lingual side (0°, 40°).
[0011] By controlling the inclination angle of the upper correction slot within the range of 0° to 40° less than the current inclination angle of the patient's teeth, a gentle and effective correction force can be achieved.
[0012] Preferably, the inclination angle range of the upper correction groove toward the lingual side is (0°, 40°].
[0013] The inclination angle range of the upper correction groove toward the lingual side is (0°, 40°], which can adapt to the inclination of the upper front teeth of most patients while providing sufficient correction force. When the patient wears the braces, the upper front teeth will be subjected to a force toward the labial side, thereby gradually improving the problem of the upper front teeth being too inclined toward the lingual side.
[0014] Preferably, the thickness of the jaw pad in the anterior teeth area is 0.5 mm to 3 mm greater than the patient's intermandibular space.
[0015] Preferably, the thickness of the jaw pad in the front teeth area is 2.5 mm-7 mm.
[0016] Optionally, the upper correction groove is a tooth groove adapted to the patient's upper front teeth.
[0017] Optionally, the upper correction groove is a continuous smooth groove.
[0018] Preferably, the avoidance groove is a continuous smooth groove; the depth of the avoidance groove is 0.5mm-4mm greater than the height of the patient's posterior teeth.
[0019] Preferably, the appliance body is an integrally formed structure.
[0020] Preferably, the appliance body is made of at least one of silicone, thermoplastic elastomer, TPU, TPE, polyurethane, nylon, and PETG.
[0021] Beneficial effect: The closed deep overbite orthodontic appliance provided by the present application includes an appliance main body having a jaw pad, an upper receiving groove and a lower receiving groove. The thickness of the jaw pad in the anterior tooth area is greater than the patient's resting jaw space so that the patient's jaws can open and bite, thereby providing space for the teeth to move. The anterior tooth area of the upper receiving groove is respectively provided with an upper correction groove, and the inclination angle of the upper correction groove is smaller than the inclination angle of the patient's upper front teeth. The difference in the inclination angle of the upper correction groove is used to apply a continuous correction force. The posterior tooth area of the upper and lower receiving grooves is provided with a avoidance groove for the posterior teeth to extend, so that the upper front teeth and the lower front teeth are gradually separated in the upper and lower directions; thereby effectively correcting the problem of closed deep overbite.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.
[0029] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.
[0030] Please refer to Figure 1-Figure 3 In some embodiments of the present application, a closed deep overbite appliance is a occlusal induction appliance, comprising an appliance body 1 having a jaw pad 105, an upper receiving groove 101 and a lower receiving groove 102, wherein the upper receiving groove 101 is used to accommodate the patient's upper teeth, and the lower receiving groove 102 is used to accommodate the patient's lower teeth; the thickness of the jaw pad 105 in the anterior tooth area is greater than the patient's interocclusal space; the anterior tooth area of the upper receiving groove 101 is provided with an upper correction groove 2, and the posterior tooth area of the upper receiving groove 101 and the posterior tooth area of the lower receiving groove 102 are both provided with avoidance grooves 4; the inclination angle of the upper correction groove 2 toward the lingual side is smaller than the inclination angle of the patient's upper anterior teeth toward the lingual side, and the avoidance groove 4 is used to provide extension space for the patient's posterior teeth.
[0031] The principle of this design is to make the thickness of the jaw pad 105 in the front teeth area greater than the resting jaw space so that the patient's jaws open and bite to provide space for the teeth to move. At the same time, the difference in the inclination angle of the correction groove is used to apply a continuous corrective force. The effect of this force is slow but continuous, which can gradually change the inclination angle of the teeth. In conjunction with the avoidance groove 4, an elongation space is provided for the posterior teeth to elongate (i.e. grow taller), so that the upper front teeth and the lower front teeth are gradually separated in the upper and lower directions (so that the upper front teeth cannot cover the lower front teeth), thereby effectively correcting the problem of closed deep overbite.
[0032] It should be noted that if the patient's lower front teeth also have a lingual tilt and need correction, a lower correction groove 3 (such as Figure 1-Figure 3 As shown), wherein the inclination angle of the lower correction groove 3 toward the lingual side is smaller than the inclination angle of the patient's lower front teeth toward the lingual side.
[0033] refer to Figure 4 In this application, the inclination angle of the upper front tooth e1 toward the lingual side refers to the angle a of the positive direction of the tooth axis f1 of the upper front tooth e1 (the positive direction is the direction from the root of the upper front tooth e1 to the crown of the upper front tooth e1 along the tooth axis f1) relative to the normal vector o1 pointing downward to the jaw plane F, which is deflected toward the lingual side; correspondingly, with reference to Figure 5 The inclination angle of the upper correction groove 2 toward the lingual side refers to the angle c of the positive direction of the alveolar axis g1 (the positive direction is the direction from the groove opening of the upper correction groove 2 to the groove bottom of the upper correction groove 2 along the alveolar axis g1) corresponding to the tooth axis f1 of the upper front tooth e1, which is deflected toward the lingual side relative to the downward normal vector o1 of the jaw plane F.
[0034] refer to Figure 4 In this application, the inclination angle of the lower front teeth toward the lingual side refers to the angle b of the positive direction of the tooth axis f2 of the lower front tooth e2 (the positive direction is the direction from the root of the lower front tooth e2 to the crown of the lower front tooth e2 along the tooth axis f2) relative to the normal vector o2 pointing upward to the jaw plane F. Correspondingly, with reference to Figure 5 The inclination angle of the lower orthodontic groove 3 toward the lingual side refers to the angle d at which the positive direction of the alveolar axis g2 (the positive direction is the direction from the groove opening of the lower orthodontic groove 3 to the groove bottom of the lower orthodontic groove 3 along the alveolar axis g2) corresponding to the tooth axis f2 of the lower orthodontic groove 3 and the lower anterior tooth e2 is deflected toward the lingual side relative to the upward normal vector o2 of the jaw plane F.
[0035] Preferably, the inclination angle of the upper correction groove 2 toward the lingual side is smaller than the inclination angle of the patient's upper front teeth toward the lingual side (0°, 40°).
[0036] The inclination angle of the upper correction groove 2 toward the lingual side is smaller than the inclination angle of the patient's upper front teeth toward the lingual side (0°, 40°], which can gradually guide the upper front teeth to rotate toward the labial side, correcting the problem of excessive inclination of the upper front teeth toward the lingual side.
[0037] When the lower correction groove 3 is provided in the front tooth area of the lower receiving groove 102, the inclination angle of the lower correction groove 3 toward the lingual side is smaller than the inclination angle of the patient's lower front teeth toward the lingual side (0°, 40°).
[0038] The inclination angle of the lower correction groove 3 toward the lingual side is smaller than the inclination angle of the patient's lower front teeth toward the lingual side (0°, 40°], which can gradually guide the lower front teeth to rotate toward the labial side and correct the problem of excessive inclination of the lower front teeth toward the lingual side.
[0039] It should be noted that the entire treatment process is generally divided into multiple treatment stages to gradually improve and correct the condition of closed deep overbite. Corresponding closed deep overbite appliances need to be designed in each treatment stage. As the treatment process progresses, the inclination angle of the correction slot in the closed deep overbite appliance will gradually decrease. The correction amount of the inclination angle of the front teeth in a single treatment stage is generally not more than 40° to avoid excessive correction force that may cause discomfort or even damage to the teeth or jaw.
[0040] In practice, the inclination angles of the upper and lower orthodontic grooves 2 and 3 can be adjusted based on the patient's specific condition. For example, for patients with severe lingual inclination of the upper front teeth, the inclination angle of the upper orthodontic groove 2 can be set to be 25°-40° less than the patient's upper front teeth. For patients with mild lingual inclination of the upper front teeth, the inclination angle of the upper orthodontic groove 2 can be set to be 5°-25° less than the patient's upper front teeth. Similarly, the inclination angle of the lower orthodontic groove 3 can be adjusted accordingly based on the degree of inclination of the patient's lower front teeth.
[0041] This design not only provides personalized correction solutions for different patients' dental conditions, but also allows for gradual adjustment of the correction force during treatment. For example, in the early stages of treatment, the inclination angle of the upper and lower correction slots can be set to a larger angle close to 40° to provide a stronger correction force. As the correction progresses, the angle difference can be gradually reduced to close to 0° to achieve finer adjustment.
[0042] Preferably, the inclination angle range of the upper correction groove 2 toward the lingual side is (0°, 40°].
[0043] The inclination angle range of the upper correction groove 2 toward the lingual side is (0°, 40°], which can adapt to the inclination of the upper front teeth of most patients while providing sufficient correction force. When the patient wears the braces, the upper front teeth will be subjected to a force toward the labial side, thereby gradually improving the problem of the upper front teeth being too inclined toward the lingual side.
[0044] When the lower correction groove 3 is provided in the front tooth area of the lower receiving groove 102, the inclination angle range of the lower correction groove 3 toward the lingual side is (0°, 40°).
[0045] The inclination angle range of the lower correction groove 3 toward the lingual side is (0°, 40°], which can adapt to the inclination of the lower front teeth of most patients while providing sufficient correction force. When the patient wears the braces, the lower front teeth will be subjected to a force toward the labial side, thereby gradually improving the problem of the lower front teeth being too inclined toward the lingual side.
[0046] This application provides a flexible range of angle settings. For example, for the upper correction groove 2, a specific angle of 5°, 15°, 25°, or 35° can be selected based on the actual inclination of the patient's upper front teeth. Similarly, the angle of the lower correction groove 3 can also be selected between 0° and 40°. This flexibility allows the appliance to better adapt to the needs of different patients.
[0047] The thickness of the jaw pad 105 in the anterior area can be adjusted according to actual needs. Generally, the thickness of the jaw pad 105 in the anterior area is 0.5mm-3mm greater than the patient's interdental space. This range of angles can meet the correction requirements of most patients. Since the interdental space is typically 2mm-4mm, the thickness of the jaw pad 105 in the anterior area is generally 2.5mm-7mm (the thickness of the jaw pad 105 in the posterior area can be greater than that in the anterior area, resulting in a thickness range of 2.5mm-9.5mm).
[0048] There are many possible implementation methods for the design of the upper correction slot 2 and the lower correction slot 3 of the closed deep overbite appliance.
[0049] For example, in some embodiments, the upper correction groove 2 is a tooth groove adapted to the patient's upper front teeth. When the lower tooth area of the lower receiving groove 102 is provided with a lower correction groove 3, the upper correction groove 2 is a tooth groove adapted to the patient's upper front teeth, and / or the lower correction groove 3 is a tooth groove adapted to the patient's lower front teeth. Figure 1-Figure 3 In the closed-mouth deep overbite appliance shown, the upper correction groove 2 is a tooth groove adapted to the patient's upper front teeth, and the lower correction groove 3 is a tooth groove adapted to the patient's lower front teeth.
[0050] The upper correction groove 2 is set to a tooth groove that matches the patient's upper front teeth, which can more accurately guide the correction direction and position of the upper front teeth. Similarly, the lower correction groove 3 is set to a tooth groove that matches the patient's lower front teeth, which can also more effectively guide the correction of the lower front teeth. This personalized design can make the braces more fit the patient's actual dental condition, improve wearing comfort, and at the same time can more accurately apply the correction force and improve the correction effect. Through this design, the braces can better solve the problem of improper inclination angles of the upper and lower front teeth. Combined with the design of the inclination angle of the upper correction groove 2 toward the lingual side and the inclination angle of the lower correction groove 3 toward the lingual side, the patient's front teeth can be gradually guided to move to the ideal position and angle, thereby achieving the purpose of correction. In addition, this design that matches the patient's teeth can also improve the stability and fixation effect of the braces, reduce loosening or falling off during use, and ensure the continuity and effectiveness of the correction process.
[0051] In the present application, the upper correction groove 2 and the lower correction groove 3 can be adapted to the patient's front teeth in a variety of ways. For example, the patient's tooth model can be obtained through 3D scanning technology, and then the shape and size of the tooth groove can be accurately designed based on the scan data. Another method is to use thermoplastic material, heat the appliance to a certain temperature before use, and then let the patient wear it so that the material naturally fits the shape of the teeth during the cooling process. This personalized tooth groove design combined with the overall inclination angle design of the appliance can produce better correction effects. Personalized tooth grooves can more accurately control the movement direction and speed of each tooth, while the overall inclination angle design provides a macro correction direction. The combination of the two can not only ensure the correctness of the overall correction direction, but also take into account the individual differences of each tooth, thereby achieving more accurate and efficient correction.
[0052] For another example, in some embodiments, the upper correction groove 2 is a continuous smooth groove. Specifically, when the lower correction groove 3 is provided in the anterior tooth area of the lower receiving groove 102, the upper correction groove 2 and / or the lower correction groove 3 are continuous smooth grooves. Specifically, the continuous smooth groove includes a continuous smooth front side surface, a continuous smooth rear side surface, and a continuous smooth bottom surface. The front side surface is used to abut against the front side surface of the upper or lower front teeth, the rear side surface is used to abut against the rear side surface of the upper or lower front teeth, and the bottom surface can abut against the top of the upper or lower front teeth, or it can not contact the upper or lower front teeth.
[0053] The continuous, smooth surface reduces irritation to teeth and oral soft tissues, improving wearer comfort. Furthermore, the smooth grooves are easier to clean, promoting oral hygiene. This design addresses the issues of excessive or uneven localized pressure that can occur with traditional braces by providing a continuous, smooth correction surface. The continuous, smooth grooves better adapt to the natural shape of teeth, providing more balanced force distribution during correction, resulting in more effective and comfortable correction. Furthermore, the smooth surface reduces the accumulation of food debris, facilitating cleaning and contributing to oral health.
[0054] The design of continuous smooth grooves can be achieved in a variety of ways. For example, 3D printing can be used to create continuous smooth grooves with precise curves, or mold forming can be used to create grooves with smooth inner surfaces. The groove's cross-sectional shape can be U-shaped, V-shaped, or other curved shapes that suit the tooth's morphology to ensure a good fit with the tooth surface.
[0055] Specifically, see Figure 1-Figure 3The avoidance groove 4 is a continuous smooth groove, and the depth of the avoidance groove 4 is greater than the height of the patient's posterior teeth. Specifically, the avoidance groove 4 includes a continuous smooth front side surface, a continuous smooth back side surface, and a continuous smooth bottom surface. The front side surface is used to abut against the front side surface of the upper or lower posterior teeth, and the back side surface is used to abut against the back side surface of the upper or lower posterior teeth. Since the depth of the avoidance groove 4 is greater than the height of the patient's posterior teeth, there is a gap between the bottom surface and the top of the upper or lower posterior teeth.
[0056] The continuous, smooth groove design offers advantages such as strong adaptability, high comfort, ease of cleaning, simple fabrication, and adaptive correction. By adopting this design, closed-end deep overbite appliances can maintain corrective effectiveness while improving wearing comfort and ease of use, thereby enhancing patient compliance and corrective results. Furthermore, the continuous structural design prevents food residue from accumulating, facilitating daily cleaning and promoting oral hygiene.
[0057] The relief groove 4 forms an integral part of the anterior teeth correction structure. When a patient wears a closed deep overbite appliance, the anterior teeth correction structure primarily applies corrective force to the anterior teeth, while the relief groove 4 provides stable support and space for the posterior teeth to grow. This design not only effectively corrects closed deep overbite but also ensures comfort and functionality in the posterior teeth, achieving a harmonious overall oral cavity.
[0058] The gap between the bottom surface of the relief groove 4 and the top of the corresponding upper or lower posterior tooth can be adjusted according to actual needs. Generally, the height to promote the extension of the patient's posterior teeth is 0.5mm-4mm, so the gap is 0.5mm-4mm, that is, the depth of the relief groove 4 is 0.5mm-4mm greater than the height of the patient's posterior teeth. Within this range, the anterior teeth can be opened by 2mm-6mm, which can meet the correction requirements of most patients.
[0059] Specifically, the orthodontic appliance body 1 also includes a labial side wall 103 and a lingual side wall 104, and the jaw pad 105 is connected between the labial side wall 103 and the lingual side wall 104. The upper part of the labial side wall 103, the upper part of the lingual side wall 104 and the upper surface of the jaw pad 105 form an upper receiving groove 101, and the lower part of the labial side wall 103, the lower part of the lingual side wall 104 and the lower surface of the jaw pad 105 form a lower receiving groove 102.
[0060] The structural design of the appliance body 1 plays a key role in resolving the aforementioned technical issues. The labial sidewalls 103 and lingual sidewalls 104 correspond to the labial and lingual sides of the teeth, respectively, providing lateral support for the upper and lower receiving slots. The jaw pad 105 connects the labial and lingual sidewalls 103 and 104, forming the bottom of the receiving slot. This structural design enables the upper and lower receiving slots 101 and 102 to accommodate the patient's upper and lower dentition, respectively.
[0061] Preferably, the appliance body 1 is an integrally formed structure.
[0062] Designing the appliance body 1 as an integrally molded structure simplifies the production process, reduces the number of parts, and improves the integrity and stability of the product. This design helps reduce production costs and shortens the production cycle, while also improving product quality consistency. By adopting an integrally molded structure, the connection and assembly process between multiple components can be avoided, reducing potential assembly errors and quality risks. The integrally molded appliance body 1 has greater structural integrity, more evenly distributing stress within the oral cavity, and improving the stability of the correction effect. Furthermore, the integral molding process reduces gaps and dead spots within the appliance, facilitating cleaning and maintenance, and improving user comfort and hygiene.
[0063] The one-piece molded structure described in this application can be achieved in a variety of ways. For example, injection molding can be used to mold the entire appliance body 1 in one go. This method can achieve complex three-dimensional structures while ensuring product consistency. Another possible implementation method is 3D printing, which allows for more precise control of the appliance's shape and internal structure. Regardless of the method used, the key to one-piece molding is to design and manufacture the upper receiving groove 101, lower receiving groove 102, upper correction groove 2, lower correction groove 3, and the entire housing of the appliance body 1 as a single unit.
[0064] The appliance body 1 may be made of at least one of silicone, thermoplastic elastomer, TPU, TPE, polyurethane, nylon, and PETG.
[0065] Choosing materials such as silicone, thermoplastic elastomers, TPU, TPE, polyurethane, nylon, and PETG to prepare the brace body 1 has many advantages. These materials have good elasticity and flexibility, can fit tightly to the tooth surface, and provide a comfortable wearing experience. At the same time, they also have a certain hardness and strength, which can apply appropriate force to the teeth during the correction process to achieve an effective correction effect. These materials have good biocompatibility and will not cause irritation or allergic reactions to oral tissues, ensuring the safety of the brace. Some materials, such as TPU and TPE, are thermoplastic and can be shaped by heating, facilitating personalized customization based on the patient's tooth shape. These materials also have a certain degree of wear resistance and durability, which can extend the service life of the brace and reduce the frequency of replacement. By selecting these materials to prepare the brace body 1, the basic functions of a closed deep overbite brace can be achieved, namely accommodating the upper and lower dentitions and correcting the anterior area. At the same time, the characteristics of these materials can also improve the comfort, safety, and durability of the brace, thereby enhancing the overall correction effect and patient experience.
[0066] The materials selected in this application can be combined to meet the needs of different patients. For example, a composite material of silicone and TPU can be selected to make the brace body 1. Silicone has excellent elasticity and biocompatibility, providing a comfortable wearing experience; while TPU has good strength and wear resistance, ensuring the lifespan of the brace. This combination can fully utilize the advantages of both materials and realize the multiple functions of the brace.
[0067] When selecting materials, it's also important to consider the functional requirements of different parts of the appliance. For example, a harder material like PETG or nylon might be used in the anterior area to provide adequate correction force, while a softer material like TPE or thermoplastic elastomer might be used in the posterior area to increase wearing comfort. This differentiated material selection allows the appliance to achieve optimal results in different areas.
[0068] The technical solution of this application solves the technical problem of material selection for closed deep overbite braces by rationally selecting materials. The selected materials provide sufficient corrective force while ensuring wearer comfort, while also exhibiting good biocompatibility and durability. This material selection significantly improves the overall performance of the braces, enabling them to better meet the needs of diverse patients.

[0070] The above description is merely an embodiment of the present application and is not intended to limit the scope of protection of the present application. For those skilled in the art, various modifications and variations of the present application are possible.
