Description

Technical Field

[0001] This utility model belongs to the field of orthodontic technology, specifically relating to an auxiliary guiding device for orthodontic invisible or fixed treatment. Background Technology

[0002] In orthodontic treatment, insufficient guiding force is often encountered when guiding the eruption of impacted teeth. The reason for this is often that the traction hooks on invisible or fixed aligners are too close to the impacted teeth being tractioned. The most commonly used and smallest traction device in orthodontics is the orthodontic traction belt, whose minimum diameter is usually 1 / 8 inch, which is often much larger than the distance between the traction point and the tooth being tractioned. This makes it impossible to apply elastic traction force effectively, thus affecting the guiding eruption effect. Summary of the Invention

[0003] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an auxiliary guide device for orthodontic invisible or fixed orthodontic treatment. This device solves the problem that the distance between the traction tooth and the traction point is too close during the process of guiding the eruption of impacted teeth, which prevents the effective application of elastic traction force. It can improve the effect of orthodontic treatment and the patient's comfort. By attaching a back hook device to the target tooth to provide the guide point, the distance between the traction hook of the invisible or fixed orthodontic appliance and the impacted tooth is effectively increased. This provides deformation conditions for the traction force application device (such as a rubber band or chain, tension spring, etc.) and makes it possible for the user to attach the rubber band (or chain) or tension spring for traction. It has the characteristics of simple structure and convenient operation.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An auxiliary guiding device for orthodontic invisible or fixed braces includes:

[0006] An adhesive-bonded retraction device includes an adhesive base plate and a retraction hook. The adhesive base plate is bonded to the target erupting tooth. The lower end of the adhesive-bonded retraction device is bent upward and bonded to the adhesive base plate. The upper end extends in the gingival direction, bypassing the gingival soft tissue covering the impacted tooth, and extends in the gingival direction to form a horizontal downward-curving hook between the gingival margin and the vestibule, i.e., the retraction hook.

[0007] At least one orthodontic loop, which is used to connect the upper return hook to the traction hook on the orthodontic invisible or fixed appliance;

[0008] A traction hook on an orthodontic clear or fixed aligner, which serves as an anchor point for connection to the upper bracket. Anchor points on clear or fixed aligners include brackets, various forms of bends, and accessories or traction devices for various clear aligners.

[0009] The adhesive base plate is made of materials including stainless steel, bioceramics, or composite resin.

[0010] The aforementioned top hook is made of stainless steel, bioceramic, or composite resin and has a diameter of 1.0mm-3.0mm.

[0011] The orthodontic brace is replaced by a tension spring or a leather chain.

[0012] The beneficial effects of this utility model are:

[0013] Increased traction distance: This utility model, through the design of an adhesive-bonded upward traction device, effectively increases the traction distance of invisible or fixed orthodontic traction hooks and impacted teeth, solving the problem that elastic traction force cannot be effectively applied.

[0014] Improved traction effect: This invention utilizes the traction force of elastic rubber bands (or chains) to effectively pull impacted teeth in the right direction, thereby improving the orthodontic treatment effect.

[0015] Easy to operate: Users can attach the leather band (or leather chain) themselves for traction, eliminating the need for frequent intervention by doctors, thus improving the convenience of treatment and patient comfort.

[0016] This utility model's adhesive-type upward traction device, through its unique design, effectively increases the distance between the traction hook of the invisible or fixed orthodontic appliance and the impacted tooth, solving the problem that elastic traction force cannot be effectively applied.

[0017] The orthodontic brace (or chain) of this invention adopts conventional specifications, is easy to obtain and replace, and can adapt to traction needs of different distances.

[0018] The orthodontic invisible or fixed traction hook of this invention is coordinated with the overall structure of the orthodontic appliance to ensure the smooth transmission of traction force and improve the guidance effect.

[0019] The method of this invention is simple and easy to implement, and patients can operate it themselves, which improves the convenience and comfort of treatment. Attached Figure Description

[0024] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] See Figure 1 An auxiliary guiding device for orthodontic invisible or fixed orthodontic treatment, comprising:

[0026] An adhesive-bonded retraction device 3 includes an adhesive base plate 4 and a retraction hook 1. The adhesive base plate is bonded to the target erupting tooth. The lower end of the adhesive-bonded retraction device is bent upward and bonded to the adhesive base plate. The upper end extends in the gingival direction, bypassing the gingival soft tissue covering the impacted tooth, and extends in the gingival direction to form a horizontally downward-curving hook between the gingival margin and the vestibule, i.e., the retraction hook.

[0027] At least one orthodontic traction collar (or chain). Traction collars (or chains) are commonly used auxiliary tools in orthodontic treatment. They are made of elastic material and are usually round or oval in shape.

[0028] Orthodontic loops are used to connect the upper return hooks to the traction hooks on orthodontic invisible or fixed aligners;

[0029] A traction hook 2 is provided on an orthodontic clear or fixed aligner, serving as an anchor point for connection to an upper return hook. Anchor points on the clear aligner 7 or fixed aligner 6 are not limited to traction hooks, but also include brackets, various forms of bends, and accessories or traction devices for each clear aligner.

[0030] The adhesive base plate can be made of stainless steel, or it can be made of ceramic or resin.

[0031] The aforementioned return hook is made of stainless steel, ceramic, or resin with a diameter of 1.0mm-3.0mm.

[0032] The orthodontic brace is replaced by a tension spring or a leather chain.

[0033] Adhesive-bonded retraction device: Structural description: This device consists of an adhesive base plate and a retraction hook. The adhesive base plate is securely bonded to the target erupting tooth using standard orthodontic bonding techniques. The retraction hook extends from the base plate, initially extending in the occlusal direction (around the gum line), bypassing the gingival soft tissue, and then extending in the gingival direction (around the gum line), ultimately forming a downward-curving hook at the level of the vestibule. Function: This device provides sufficient traction distance for invisible or fixed aligners, allowing the elastic traction to smoothly connect the traction hook and retraction hook on the aligner, thereby applying effective traction force.

[0034] Traction loops (or chains) or tension springs: Standard orthodontic loops are used, such as 2.0 or 3.5 ounces. Specific diameters such as 1 / 4, 1 / 8, and 3 / 16 ounces can be selected as needed. Chains can be short or medium-length. Tension springs of different sizes can also be used, depending on the situation. Function: As a medium for transmitting elastic traction force, it transfers the traction force from the orthodontic appliance to the impacted teeth through the upper retraction hook, achieving a guided eruption effect.

[0035] Fixed orthodontic appliances are orthodontic devices that are cemented to the teeth by a dentist and cannot be removed by the patient. They typically consist of three parts: bands, brackets, and archwires. Invisible orthodontic appliances are invisible and aesthetically pleasing orthodontic devices designed and manufactured using computer-aided 3D technology, and are usually made of polymer materials.

[0036] Orthodontic invisible or fixed traction hooks: These are pre-installed or handcrafted traction structures on invisible or fixed aligners, used to connect with adhesive-back traction hooks via leather loops (or chains) or tension springs. Function: They serve as anchor points for traction force, forming a complete traction system together with the back hooks and leather loops (or chains).

[0037] Preparation of auxiliary germination device

[0038] Fabrication of the adhesive-bonded upward traction device: A suitable adhesive base plate and upward traction hook are customized based on the morphology and size of the target guide tooth. The adhesive base plate should have good adhesive properties and biocompatibility; the upward traction hook should have sufficient elasticity and strength to ensure effective transmission of traction force.

[0039] Orthodontic ties (or chains) selection: Choose the appropriate orthodontic ties (or chains) according to actual needs.

[0040] Preparation of invisible or fixed orthodontic appliances: Ensure that the pre-set traction hooks on the invisible or fixed orthodontic appliances are in the correct and secure position.

[0041] The adhesive base plate has good adhesive properties and biocompatibility, and can be firmly bonded to the target erupting tooth.

[0042] The upward traction hook has a certain degree of elasticity and strength to ensure the effective transmission of traction force.

[0043] The orthodontic loops are tension springs or push springs of different sizes and diameters, as well as conventional orthodontic loops, with sizes including but not limited to 3.5 ounces or 2 ounces (1 / 4 inch, 1 / 8 inch, 3 / 16 inch, etc.) to meet different traction requirements of distance and intensity.

[0044] The position and shape of the orthodontic invisible or fixed traction hook are coordinated with the overall structure of the orthodontic invisible or fixed appliance to ensure the smooth transmission of traction force.

[0045] The adhesive-bonded upward traction device, orthodontic braces (or chains), and orthodontic invisible or fixed traction hooks together constitute a complete traction system used to pull impacted teeth in the lateral direction to achieve the effect of guiding eruption.

[0046] When auxiliary guiding devices are used in orthodontic invisible or fixed braces, they include:

[0047] The adhesive base plate of the adhesive-type upward traction device is bonded to the target guide tooth to ensure a firm bond;

[0048] Choose a suitable orthodontic loop (or chain) and place it between the upper hook of the adhesive upper traction device and the traction hook on the orthodontic invisible or fixed aligner to form a complete traction system;

[0049] Once the orthodontic invisible or fixed aligners are in place, the impacted teeth are pulled in the opposite direction by the elastic traction of the orthodontic loops (or chains). The loops (or chains) or tension springs are replaced regularly to maintain the effectiveness of the traction.
