Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, and in particular to a non-invasive anterior tooth intrusion correction device, specifically a non-invasive device for solving the problem of vertical elongation of anterior teeth in tooth extraction cases, belonging to the field of medical devices. Background Technology

[0002] In modern orthodontic treatment, anterior tooth retraction is a common and crucial procedure in the treatment of extraction cases. However, due to insufficient biomechanical design and control, the following technical challenges often arise during the treatment:

[0003] ① Lingual tipping of anterior teeth: During the retraction process, the anterior teeth may tilt lingually due to improper force application, leading to disorder of the dental arch shape and occlusal relationship. This phenomenon increases the complexity of treatment and negatively affects the final aesthetics and functionality.

[0004] ② Vertical elongation (roller coaster effect): When the anterior teeth are retracted, they are prone to excessive elongation due to a lack of effective vertical control. This "roller coaster effect" will make the overall shape of the dental arch uneven, seriously affecting the treatment effect and patient satisfaction.

[0005] ③ Insufficient anchorage: In orthodontic treatment, traditional methods rely on adjacent teeth as anchorage units. However, insufficient anchorage of adjacent teeth may lead to adverse mechanical effects, such as unintended movement of the anchoring teeth.

[0006] To address these issues, academia and industry have developed various techniques, particularly the introduction of temporary anchorage devices (TADs), which provide reliable support for orthodontic treatment. This method has become an important tool for treating complex cases, including those involving vertical elongation. Specifically, it mainly includes:

[0007] ① Successful application of TADs in vertical control: Miniature implants excel in vertical control due to their absolute anchorage capacity. Studies have shown that they can effectively prevent vertical elongation of anterior teeth while providing important support for the stability of three-dimensional orthodontic forces.

[0008] ② Three-dimensional control and biomechanical optimization: Clinical studies have further validated the three-dimensional biomechanical control capabilities of TADs in complex cases. In particular, significant corrective effects were achieved through TADs in the retraction of maxillary anterior teeth and the stabilization of posterior teeth.

[0009] Although miniature implants have achieved remarkable results in many complex cases, their limitations are also evident, mainly in the following aspects:

[0010] ①Invasive issues: Miniature implants need to be surgically inserted and fixed into the patient's jawbone. This process may lead to postoperative pain, infection risk, psychological stress, and patient resistance to surgery.

[0011] ② Poor patient comfort: During long-term treatment, implants may cause inconvenience to patients' daily lives, such as the contact and friction between the implant surface and the oral soft tissue, which to some extent reduces patients' treatment compliance.

[0012] ③ High cost and complexity: The application of mini implants requires precise preoperative positioning and surgical skills, which not only increases the workload of doctors but also significantly increases treatment costs.

[0013] Therefore, in recent years, with the increasing demand from patients for low-invasiveness and comfort, non-invasive orthodontic techniques have gradually become an important research direction:

[0014] ① Advances in clear aligners: Clear aligners, as aesthetically pleasing and highly acceptable devices for patients, have achieved certain results in achieving three-dimensional control of tooth force. However, their application in complex cases (such as vertical elongation) remains limited, requiring further mechanical optimization.

[0015] ② The emergence of innovative mechanical design: Based on the design trend of non-invasive orthodontic treatment, more and more new devices adopt optimized mechanical structures, combining archwire deformation with orthodontic force to achieve a similar orthodontic effect to implants.

[0016] However, there is currently no practical product on the market that can achieve non-invasive orthodontic treatment. Utility Model Content

It features a mechanically optimized design that utilizes archwire deformation to achieve vertical control force, achieving highly efficient correction without the need for additional devices. Furthermore, it achieves adaptability and simplicity, seamlessly integrating with existing orthodontic systems, facilitating easy installation, and reducing manufacturing costs.

[0042] Specifically, Figure 1 A schematic diagram of the overall structure of a non-invasive anterior tooth intrusion correction device according to a preferred embodiment of the present invention is shown. For example, in a specific implementation example, Figure 1 The non-invasive anterior intrusion correction appliance shown can be advantageously used to achieve anterior tooth retraction, for example, in tooth extraction treatment.

[0043] like Figure 1 As shown, the non-invasive anterior tooth intrusion correction device according to a preferred embodiment of the present invention includes: a frame 10, a first end fixing buckle 20, a second end fixing buckle 30, a first elastic ring 40, a second elastic ring 50, and a fixing component 60; wherein, the first end fixing buckle 20 and the second end fixing buckle 30 are respectively connected to the two ends of the frame 10 for fixing to the orthodontic archwire; the fixing component 60 is arranged in the middle position of the frame 10, the first elastic ring 40 is arranged on the first side of the frame 10 and between the first end fixing buckle 20 and the fixing component 60, and the second elastic ring 50 is arranged on the second side of the frame 10 and between the second end fixing buckle 30 and the fixing component 60.

[0044] The fixing component 60 is fixed at the location of the two anterior teeth. For example, the fixing component 60 is fixed at the location of the two anterior teeth by a connecting element (e.g., adhesive), or the fixing component 60 is fixed at the location of the two anterior teeth by an orthodontic archwire fixed to the two anterior teeth.

[0045] Preferably, the non-invasive anterior intrusion correction device is made entirely from a single piece of material.

[0046] Preferably, the first end fixing buckle 20 and the second end fixing buckle 30 are symmetrically arranged with respect to the fixing component 60, and / or the first elastic ring 40 and the second elastic ring 50 are symmetrically arranged with respect to the fixing component 60, and / or the frame 10 has a left-right symmetrical structure and the fixing component 60 is located on the axis of symmetry of the frame 10.

[0047] Preferably, the first end fixing buckle 20 and the second end fixing buckle 30 are connected to the two ends of the frame 10 through the first extension portion 21 and the second extension portion 31, respectively, and the first extension portion 21 and the second extension portion 31 have curvatures to accommodate the tooth arrangement.

[0048] Preferably, the frame 10 includes a bottom segment and side segments extending upward from both ends of the bottom segment, and the fixing member 60 is arranged in the center of the bottom segment, and the first elastic ring 40 and the second elastic ring 50 are respectively arranged at the upper ends of the corresponding side segments.

[0049] Preferably, the first elastic ring 40 and the second elastic ring 50 are elastic rings composed of multiple circles. The number of circles in the first elastic ring 40 and the second elastic ring 50 may be the same or different, and the diameter of the circles may be the same or different.

[0050] Preferably, the fixing component 60 is a fixing ring. Of course, the fixing component 60 can also be other shapes of rings or hooks, etc.

[0051] In this invention, the pressure force can be precisely controlled by increasing or decreasing the number of elastic rings; and elastic rings of different diameters or materials can be used to provide corrective forces of different intensities.

[0052] As can be seen, the two end fasteners are located at both ends of the device and are used to fix it to the patient's orthodontic archwire, ensuring a stable installation and the transmission of corrective force. The middle frame can be a rectangular frame formed by bending a section of stainless steel wire (or other alternative material). A fixing ring is located in the center of the frame to connect to the fixing point (or other auxiliary device) placed between the patient's two anterior teeth. The elastic rings (two-sided ring structures) are elastic rings designed on both sides of the rectangular main frame, acting like springs to generate vertical corrective force. The middle fixing ring connects to the anterior teeth through the connection point, applying downward pressure through the deformation force of the device to inhibit the vertical elongation of the anterior teeth.

[0053] Preferably, the dimensions can be adjusted according to the spacing and shape of the patient's anterior teeth, such as adjusting the height and width of the frame, to optimize the force application effect.

[0054] Moreover, for example, in special cases, the frame shape can be designed asymmetrically to accommodate special dentition or dental arch morphology.

[0055] Preferably, this invention can add a mechanical adjustment function to meet the corrective force requirements of more complex cases.

[0056] Regarding the selection of materials for the device, in addition to traditional stainless steel, the design of this utility model also covers other materials that combine rigidity and elasticity to meet the needs of different clinical scenarios, such as:

[0057] ①Metallic materials

[0058] Titanium alloys are lightweight, have a high modulus of elasticity, and are highly corrosion resistant, making them suitable for cases requiring high strength and biocompatibility.

[0059] Nickel-titanium alloy (NiTi): It has excellent shape memory effect and superelasticity, making it suitable for elastic coil design.

[0060] ② Polymer materials

[0061] Hard plastics (polyoxymethylene resin, POM): They are rigid and durable, and easy to process into complex shapes.

[0062] Polyetheretherketone (PEEK): It has high mechanical strength and good biocompatibility, and can replace some metal materials.

[0063] Thermoplastic polyurethane (TPU): Suitable for elastic band components, providing flexibility and stability.

[0064] PETG (polyethylene terephthalate copolyester): Good transparency, easy processability, and excellent biocompatibility. Poor heat resistance and moderate abrasion resistance. Suitable for transparent orthodontic appliances and some fixation components.

[0065] ③ Composite materials

[0066] Fiber-reinforced composites: Carbon fibers or glass fibers are embedded in a polymer matrix, achieving both lightweight and high strength.

[0067] Ceramic-reinforced composite materials: possess good rigidity and corrosion resistance, and can be used in frame components.

[0068] In the preferred embodiment, the frame material is selected from titanium alloy, PEEK and fiber-reinforced composite materials, the elastic ring material is selected from nickel-titanium alloy and TPU, the fixation component material is selected from stainless steel, PEEK and ceramic-reinforced composite materials, and the material of the clear brace and auxiliary components is selected from PETG (suitable for clear braces and fixation buckles, brackets, etc. that do not bear large forces).

[0069] This invention can also use titanium alloy or other shape memory materials to replace stainless steel wire, thereby improving the device's elasticity and durability.

[0070] As can be seen, this utility model has strong adjustability. The parameters of the rectangular frame and elastic ring can be adjusted according to the patient's individual needs to adapt to different dental arch shapes and orthodontic goals. The material selection is flexible, and a variety of materials (such as titanium alloy, hard plastic, etc.) can be used to simultaneously take into account biocompatibility, mechanical properties and economy. Moreover, it has wide adaptability and is suitable for a variety of anterior tooth vertical elongation correction scenarios. In particular, it provides a safe and efficient solution for patients who are contraindicated or reject traditional implant treatment.

[0071] During the installation process, the fixing clips at both ends can be installed on the patient's orthodontic archwire to form a stable support point; then the middle fixing clip of the rectangular main frame can be connected to the fixing point in the patient's anterior tooth area (for example, at a specific position between two anterior teeth).

[0072] <Mechanical Principles of the Device>

[0073] This device combines specific geometric design with the principles of elasticity, utilizing the interaction between archwire deformation and the elastic part of the device to provide a controllable vertical depressor force for the anterior teeth. Its main mechanical characteristics are as follows:

[0074] ① Elastic energy storage principle: The elastic rings at both ends of the device deform during installation, storing elastic potential energy. This potential energy is released through elastic restoring force, forming a corrective force in the vertical direction.

[0075] ② Support and force transmission:

[0076] Fixing buckles: The fixing buckles at both ends securely connect the device to the patient's archwire, providing device resistance.

[0077] Rectangular mechanical frame: The central rectangular frame serves as the main mechanical transmission path, concentrating the deformation force of the elastic rings on both sides to the anterior teeth.

[0078] Fixed ring connection point: The fixed ring is connected to the anterior tooth fixing point, which evenly distributes the indentation force transmitted to the anterior teeth to the area that needs to be corrected.

[0079] ③ Continuous force application during the correction process: During the treatment, the elastic coil will gradually release deformation potential energy, and at the same time maintain a stable mechanical output through its elastic material properties, avoiding the mechanical attenuation problem common in traditional spring mechanical systems.

[0080] <Mechanical Analysis>

[0081] ① Mechanical properties of elastic rings

[0082] The deformation of the elastic ring is proportional to the applied force. According to Hooke's Law F=-kx (where F is the elastic force, k is the elastic coefficient, and x is the deformation), the stiffness kk and deformation x of the elastic ring in the device design can be adjusted by the material and the number of rings.

[0083] Increasing the number of elastic bands or using materials with a higher elastic modulus can provide greater corrective force.

[0084] ②The function of the rectangular frame

[0085] The rigid structure of the rectangular frame ensures the overall stability of the device and prevents excessive deformation or mechanical attenuation during force transmission.

[0086] The height and width of the rectangle can be adjusted according to the patient's needs:

[0087] Increased height: Enhances lever arm effect, providing greater vertical depressing force.

[0088] Width adjustment: Change the support position of the elastic ring to optimize the force distribution.

[0089] ③ Distribution and adjustment of pressure force

[0090] By adjusting the size of the rectangular frame and the number of elastic rings, the magnitude and direction of force applied to the anterior teeth can be precisely controlled. By reducing the number of elastic rings or decreasing the frame size, the force application needs of different patients can be accommodated.

[0091] Therefore, this utility model provides a practical and innovative non-invasive orthodontic device, whose technical advantages include:

[0092] ① Non-invasive design: This device achieves a corrective force similar to that of an implant screw through optimized archwire deformation, eliminating the need for surgical implantation and significantly improving patient comfort and treatment acceptance.

[0093] ②Low cost and high compatibility: The device is made of simple stainless steel material and can be directly and seamlessly compatible with existing orthodontic systems, reducing medical costs and operational complexity.

[0094] ③ Strong vertical control force: This device utilizes a specific mechanical point structure to effectively suppress the vertical elongation of the anterior teeth, significantly reducing the "roller coaster effect" while improving the flatness and aesthetics of the overall dental arch shape.

[0095] The technical effects of this utility model include at least the following:

[0096] • Functional alternative to implants: Provides vertical corrective force similar to that of implants, addressing the problem of vertical elongation of anterior teeth.

[0097] • Non-invasive treatment: The device is designed to eliminate the need for invasive surgery, significantly improving patient comfort.

[0098] • Low cost and high adaptability: The device has a simple structure and is directly compatible with existing orthodontic systems, requiring no additional instruments or special operations.

[0099] <Specific Implementation>

[0101] Ram's Horn Bending Type: The "ram's horn bending" device is made of 0.5 mm stainless steel wire and includes the following main structures:

[0102] 1. Fixing buckles at both ends

[0103] o is used to fix the device to the patient's orthodontic archwire, providing a stable anchorage point.

[0104] 2. Central rectangular main frame

[0105] The rectangular frame is the core of the device, used to evenly transmit the force of the elastic ring to the anterior teeth. A retaining ring is located in the middle of the frame.

[0106] 3. Fixing ring

[0107] The o connects to the fixation point between the patient's anterior teeth to achieve concentrated application of corrective forces.

[0108] 4. Elastic band

[0109] The circular elastic structures bent on both sides of the rectangular frame serve as energy storage units, generating a downward pressure force.

[0110] Installation steps

[0111] 1. Preliminary preparations

[0112] Based on the patient's anterior tooth morphology and spacing measurements, determine the height and width of the rectangular articulator.

[0113] o Select materials with appropriate rigidity and elasticity (such as stainless steel or titanium alloy) to make the device.

[0114] Adjust the diameter and number of elastic coils to match the patient's force application needs.

[0115] 2. Fixing device

[0116] Insert the two end clips into the corresponding positions on the patient's orthodontic archwire to ensure the device is secure.

[0117] o Connect the middle retaining ring of the rectangular main frame to the retaining point between the anterior teeth (e.g., by adhesive to the archwire).

[0118] 3. Force adjustment

[0119] Based on the patient's treatment needs, adjust the deformation of the elastic coil and the height of the rectangular frame to provide appropriate vertical depressurization force.

[0120] Work process

[0121] 1. After installation, the elastic ring of the device stores elastic potential energy due to deformation. When the rectangular main support is fixed between the front teeth, the elastic ring begins to release potential energy.

[0122] 2. The elastic restoring force of the elastic ring is concentrated and transmitted to the anterior teeth through the rectangular frame, forming a vertically downward depressing force.

[0123] 3. As treatment progresses, the elastic band continues to apply force, gradually correcting the vertical elongation of the anterior teeth while maintaining the flatness of the dental arch.

[0124] Corrective effect

[0125] 1. Correction goals achieved

[0126] After three months of treatment, the patient's problem of vertical elongation of the anterior teeth has significantly improved, the dental arch shape has been restored to a flat state, and the occlusal relationship between the anterior and posterior teeth is normal.

[0127] 2. Comfort and compliance

[0128] The patient did not experience significant discomfort, had a high acceptance rate, and did not require surgical implantation of a nail.

[0129] Summary of advantages

[0130] 1. Non-invasive design: No surgical implantation is required, reducing patient suffering and improving treatment acceptance.

[0131] 2. Highly adjustable: By adjusting the size of the rectangular frame and the number of elastic coils, it can adapt to the correction needs of different patients.

[0132] 3. Low cost: The device is simple to manufacture and uses a variety of materials, which significantly reduces treatment costs.
