Description

Technical Field

[0001] This utility model relates to the field of orthodontics, and in particular to an oral endocrine device. Background Technology

[0002] During jawbone growth and development, cysts can be non-neoplastic cystic lesions that appear within the jawbone due to various reasons. These cysts typically form near the roots of the teeth in the maxilla and mandible, including the growth areas of deciduous and permanent teeth. Cysts in the tooth growth area can affect normal tooth growth; specifically, if the cyst is large or interferes with normal tooth growth, treatment may be necessary.

[0003] Common treatments include surgical removal of the cyst and fenestration to shrink it. When the cyst is too large and complete removal may affect jawbone development or nearby teeth, fenestration may also be considered to reduce the impact of the cyst on the teeth.

[0004] After cyst removal or fenestration, a wound will remain in the gum area, allowing the previously blocked tooth to grow normally. If the cyst removal surgery involves surrounding bone tissue, the healing and remodeling process of the bone tissue may prevent the tooth from passing through the wound, which could affect tooth growth. Utility Model Content

[0005] To solve or at least partially solve the above-mentioned technical problems, the embodiments of this utility model provide the following technical solutions.

[0006] In one embodiment, the present invention provides an oral implantation device, comprising: a fixation frame and an expansion support component. The fixation frame is used to be positioned on the outer peripheral surface of the post-gingival wound and the tooth to maintain the overall fixation of the oral implantation device. The expansion support component is connected to the fixation frame and is used to be inserted into the post-gingival wound, abutting against the inner wall of the wound to prevent wound closure. The expansion support component has a pre-formed growth channel to provide the space required for the growth of the tooth to grow.

[0007] Furthermore, the distance between two opposite points on the sidewall of the expansion support gradually increases or decreases along the direction away from the fixation frame, and the surface of the expansion support facing the gum has an outwardly convex arc.

[0008] Furthermore, the oral appliance also includes a traction device. One end of the traction device is connected to the fixation frame, and the other end is used to connect to the tooth inside the wound. The traction device is elastic and can pull the tooth outward by releasing its own elastic potential energy.

[0009] Furthermore, the fixing frame includes a main body and an adjustment part. The adjustment part is disposed on the main body, and the traction device is connected to the adjustment part. The adjustment part acts on the traction device to increase the elastic potential energy of the traction device.

[0010] Furthermore, the adjustment section consists of several grids opened on the fixed frame, and the pulling device includes elastic wires that are wound around the grids to achieve fixation.

[0011] Furthermore, the adjustment unit also includes a rotating rod. The rotating rod is threaded, passes through the body, and is screwed to the body. One end of the rotating rod extending into the growth channel is connected to the traction device, and the rotating rod increases or decreases the elastic potential energy of the traction device by rotating.

[0012] Furthermore, the traction device includes a bearing and a tension spring. The bearing is located at the end of the rotating rod furthest from the main body, one end of the tension spring is connected to the bearing and can rotate relative to the bearing, and the other end of the tension spring is connected to teeth.

[0013] Furthermore, the main body has a rotating groove, and a through hole is provided at the bottom of the rotating groove. The main body also includes a universal rotating joint, which is inserted into the rotating groove. The rotating rod passes through the through hole and the universal rotating joint in sequence, and is threadedly connected to the universal rotating joint. The universal rotating joint is pushed to rotate within the rotating groove to adjust the posture of the rotating rod, thereby changing the angle between the length direction of the rotating rod and the length direction of the growth channel.

[0014] Furthermore, the adjustment section also includes a guide section. The guide section includes at least two guide bars, one end of which is connected to the main body. At least two guide bars are arranged on opposite sides of the rotating rod to guide the movement direction of the rotating rod.

[0015] Furthermore, the oral appliance also includes a protective cap. The protective cap is fitted onto the frame to cover the growth channel. The protective cap has a tooth-mimicking surface to adapt to the tooth surfaces of opposite teeth in the oral cavity.

[0016] Furthermore, the oral appliance also includes a connecting assembly. The connecting assembly is connected to the retainer, and the connecting assembly has mating holes for fitting onto the teeth to install the retainer.

[0017] Compared with the prior art, the beneficial effects of the embodiments of this utility model are as follows:

[0018] This innovative oral appliance is designed to be placed inside the wound after cyst removal surgery. Through its close fit to the wound, it effectively supports the wound, preventing the cyst from closing prematurely due to rapid healing. This creates an open growth channel at the site of the original cyst. Teeth located below this site can continue to develop normally through this channel, avoiding the problem of tooth growth being hindered by premature gum closure. This design not only helps maintain cleanliness of the surgical area but also promotes healthy tooth growth during postoperative recovery, ensuring successful eruption of teeth after gingival cyst surgery.

[0034] The inventor of this patent discovered that although the surgery successfully removed the cyst that was obstructing tooth growth, the resulting gingival recession could lead to new problems. Specifically, after the cyst is removed, the space it originally occupied gradually shrinks due to the natural healing process of the gums, which directly affects the normal eruption and growth of the underlying teeth.

[0035] While supporting the wound, the growth of the tooth also needs to be considered. Therefore, the framework design must not only support the wound but also ensure that it does not obstruct the tooth's growth path, guaranteeing smooth tooth development. This requires not only addressing the space compression caused by gingival recession but also providing a stable and sufficient growth environment for the teeth in the affected area.

[0036] In view of this, embodiments of this patent provide an oral plugging device to solve the above-mentioned problems.

[0037] First Implementation Method

[0038] refer to Figure 1 As shown in one embodiment, this utility model provides an oral cavity applicator, which includes a fixation frame 2 and an expansion support component 1. The fixation frame 2 is used to be placed on the outer peripheral surface of a post-gum surgery wound. The expansion support component 1 is connected to the fixation frame 2 and is used to be inserted into the post-gum surgery wound, abutting against the inner wall of the wound to prevent the wound from closing. The expansion support component 1 has a pre-formed growth channel to provide the space required for the growth of the tooth to grow.

[0039] After surgery for a gingival cyst, a wound will remain where the cyst was, allowing observation of the tooth that is about to grow inside. At this point, an oral appliance is placed at the wound, and a retainer 2 is used to fix the appliance in place, ensuring it remains accurately positioned and unaffected by daily oral activities. The expansion support component 1 of the appliance extends into the wound and abuts against its inner wall. Supported by the expansion support component 1, the wound cannot contract, thus remaining open at all times.

[0040] To further optimize treatment outcomes, the oral appliance of this application can be made of titanium alloy or other medical-grade materials, possessing excellent biocompatibility and mechanical strength. It can mimic the structure of natural alveolar bone, providing a stable environment for new bone formation, thereby promoting wound healing without causing excessive contraction. Furthermore, the expansion support component 1 can be customized in shape and size according to the patient's specific needs to ensure optimal adaptability and functionality.

[0041] Because the tooth to be grown is located at the bottom of the wound, it needs to pass through the space in the wound to reach the tooth surface during growth. Therefore, the expansion support component 1 needs to avoid the tooth's growth path, and the growth channel located on the expansion support component 1 can reserve sufficient growth space for the tooth. Over time, the tooth can gradually grow and enter the growth channel until it emerges from the gingival surface and completes its growth. Once the tooth is fully exposed on the gingival surface, the oral appliance can be removed. This method not only solves the problem of space compression caused by gingival contraction, but also provides a stable and sufficient growth environment for the tooth in the affected area. It helps promote faster and better recovery of the damaged area and opens up new pathways for treatment in similar situations in the future.

[0042] Furthermore, refer to Figure 5 Figure 6As shown in some embodiments, the distance between two opposite points on the sidewall of the expansion support member 1 gradually increases or decreases along the direction away from the fixation frame 2, and the surface of the expansion support member 1 facing the gum has an outwardly convex arc surface.

[0043] The location of gingival cysts is relatively random, so the wound left after cyst removal surgery may have various orientations, while teeth typically grow upwards. Therefore, during the installation of an oral appliance, the expansion support component 1 needs to be inserted into the wound from different directions. The curved surface of the expansion support component 1 allows it to fit snugly into the wound at different angles. Even if there is a slight deviation between the opening orientation of the wound and the tooth's growth direction, the orientation of the expansion support component 1 can be adjusted to ensure that the growth channel accurately preserves space for tooth growth. Simultaneously, the curved design avoids damage to the inner wall of the wound when set at different angles, thus improving the patient experience.

[0044] Furthermore, to ensure a better fit between the expansion support component 1 and the patient's wound, 3D scanning technology can be used to acquire wound morphology data, allowing for the customization of the expansion support component and providing tailored treatment recommendations for each patient. This will significantly improve treatment efficiency and shorten the recovery period.

[0045] Second Implementation Method

[0046] In the first embodiment, an applicator with an expansion support component 1 is introduced. This design supports the wound after oral cyst surgery, preventing immediate healing and thus preserving sufficient space for tooth growth. Obviously, the applicator cannot be removed until the tooth emerges above the gum line. However, due to the slow rate of tooth growth, this means patients may need to wear the applicator for an extended period. Prolonged wound exposure increases the risk of infection and hinders patient recovery.

[0047] In view of this, refer to Figure 2 Compared to the first embodiment, the improvement of the second embodiment of this application is that the oral cavity device further includes a traction device 3. One end of the traction device 3 is connected to the fixation frame 2, and the other end is used to connect to the tooth inside the wound. The traction device 3 is elastic and can pull the tooth outward by releasing its own elastic potential energy.

[0048] After the oral appliance is installed, the two ends of the traction device 3 are connected to the fixture 2 and the tooth, respectively, and the traction device 3 is tightened, thus acquiring elastic potential energy. This traction device 3 is typically made of medical-grade stainless steel or titanium alloy, possessing good biocompatibility and corrosion resistance. Because one end is connected to the fixture 2 and the other end to the tooth, and the fixture 2 is fixed and not easily moved, the tooth can slowly move along the tightened direction of the traction device 3 under its influence, thereby accelerating tooth growth. Simultaneously, after the tooth has moved a certain distance, the elastic potential energy of the traction device 3 is released, and it becomes relaxed. At this point, the traction device 3 needs to be reconnected to the fixture 2 to re-tighten and regain elastic potential energy. The application of the traction device 3 varies among patients of different ages. For pediatric patients, whose permanent teeth erupt faster, a shorter period of wearing the traction device 3 may be necessary. Adult patients, on the other hand, may require a longer waiting and monitoring period. In some complex cases, orthodontic treatment may need to be combined to ensure that teeth grow correctly and fill the space left by cyst surgery. In such cases, the design and adjustment of the traction device 3 will be more refined to accommodate the needs of the orthodontic apparatus.

[0049] Furthermore, refer to Figure 1 , Figure 2 The mounting bracket 2 shown includes a main body and an adjustment part 22. The adjustment part 22 is disposed on the main body, and the traction device 3 is connected to the adjustment part 22. The adjustment part 22 acts on the traction device 3 to increase the elastic potential energy of the traction device 3.

[0050] Because teeth may shift direction during growth, leading to misalignment, traction devices need to be adjusted according to the specific growth pattern of the teeth to ensure they develop in the correct direction. Furthermore, as traction progresses, the elastic potential energy within the traction device gradually weakens. To restore its effectiveness, the connection points between the traction device and the 22-piece adjustment mechanism must be adjusted periodically to allow the device to regain sufficient elastic potential energy to continue functioning. As treatment progresses, the initially elastic traction material may become less resilient due to prolonged pressure, meaning it can no longer provide sufficient support to move the teeth. In such cases, a specialist will take appropriate measures based on the patient's specific situation, such as slightly reducing the traction force, replacing with more suitable components, or even completely replacing the traction system.

[0051] As treatment progresses, the initially flexible traction material may become less resilient due to prolonged pressure, meaning it may no longer provide sufficient support to move the teeth. In such cases, a specialist will take appropriate measures based on the patient's specific situation, such as slightly reducing the traction force, replacing it with a more suitable accessory, or even completely replacing the traction system to ensure that the treatment effect is not affected.

[0052] Specifically, refer to Figure 1 and Figure 2 The adjustment part 22 shown consists of several grids opened on the fixed frame 2. The pulling device 3 includes elastic wires, which are wound around the grids to achieve fixation.

[0053] Since one end of the traction device is always connected to the tooth, the traction direction can be adjusted by connecting its other end to different grids on the adjustment unit 22. By changing the position of the grids to which the traction device is fixed, force can be applied to the teeth from multiple angles. Furthermore, to make the entire process more efficient and convenient, many high-end orthodontic appliances are equipped with a specially designed sliding rail system. This system allows users to easily adjust the specific position of the traction device without causing additional damage to surrounding tissues. Specifically, the process involves first loosening the existing connection point, then moving it along the preset track to the desired area, and finally locking it in place. This design ensures that tooth movement can be effectively guided from different directions, thus guaranteeing that the teeth grow along the correct trajectory. Simultaneously, the elastic cords used maintain stable elasticity under tension and possess good flexibility, facilitating fixation and adjustment within each grid.

[0054] Third Implementation Method

[0055] In the second embodiment, by repeatedly re-fixing the traction device 3 and the adjustment part 22 after releasing the elastic potential energy, the traction device 3 can regain the elastic potential energy and pull the teeth. However, it is cumbersome to reconnect the traction device 3 and the adjustment part 22 each time.

[0056] In view of this, the improvement of the third embodiment compared to the second embodiment is that, referring to Figure 5 , Figure 6 The adjustment unit 22 also includes a rotating rod 32. The rotating rod 32 is threaded, passes through the main body, and is screwed to the main body. One end of the rotating rod 32 extending into the growth channel is connected to the pulling device 3. The rotating rod 32 increases or decreases the elastic potential energy of the pulling device 3 by rotating. This method allows for grid adjustment using a threaded rotating rod, simplifying the operation process.

[0057] When the rotating rod 32 is rotated, it can be displaced relative to the body under the action of the thread mechanism. At the same time, the traction device connected to the end of the rotating rod 32, specifically the side near the growth channel, also moves and gradually accumulates elastic potential energy in the process. Once the rotating rod 32 reaches the predetermined position, the traction device has accumulated enough energy to pull the designated tooth. At this point, rotation stops, and the rotating rod 32 is fixed in place by utilizing the locking characteristic of the thread structure, allowing the traction device full of elastic potential energy to continue acting on the tooth. As the tooth gradually moves into place, the previously stored energy is slowly released. Afterwards, the traction device can be reactivated simply by readjusting the position of the rotating rod 32, without the need for frequent disassembly or reinstallation of it to the adjustment part 22. This not only simplifies the operation process but also improves work efficiency. In addition, to facilitate better user control of this process, a large knob 221 is usually installed at the end of the rotating rod 32 away from the traction device. The entire system can be easily controlled by turning this knob 221. It is worth noting that from Figure 6 As can be seen, the knob 221 is designed to be larger than the rotating rod 32 itself. This is to prevent the rotating rod 32 from falling off the main body due to excessive force.

[0058] Specifically, refer to Figure 5 and Figure 6 The traction device 3 shown includes a bearing and a tension spring 31. The bearing is located at the end of the rotating rod 32 away from the main body. One end of the tension spring 31 is connected to the bearing and can rotate relative to the bearing. The other end of the tension spring 31 is connected to teeth.

[0059] When the tension spring 31 is stretched, it gradually accumulates elastic potential energy. Once sufficient elastic potential energy is acquired, the tension spring 31 can effectively act on the target tooth, causing it to move. However, during the movement of the tension spring 31 driven by the rotating rod 32, the rotation of the rotating rod 32 itself causes the connected tension spring 31 to rotate as well. Given that one end of the tension spring 31 is fixed to the tooth, this rotational action will cause the entire tension spring 31 to twist. This twisting will hinder the operation of the rotating rod 32. To solve this problem, a bearing can be installed between the tension spring 31 and the rotating rod 32. This allows for relatively independent rotation between the two, allowing the tension spring 31 to extend and retract freely without rotating with the rotating rod 32, thus avoiding additional stress caused by torsion and reducing the frictional force during the operation of the rotating rod 32.

[0060] Fourth Implementation Method

[0061] In the third embodiment, the rotation of the rotating rod 32 drives the movement of the traction device 3, enabling the traction device 3 to acquire elastic potential energy, which is then used to pull the tooth. However, the tooth to be grown is not in a standard position and requires external force to accurately guide its growth direction.

[0062] In view of this, the improvement of the fourth embodiment compared to the third embodiment is that a rotating groove is provided on the main body, and a through hole is provided at the bottom of the rotating groove. The main body also includes a universal rotating joint, which is snapped into the rotating groove. The universal rotating joint allows the rotating rod to adjust its angle in three-dimensional space to adapt to changes in the tooth growth direction. The rotating rod 32 passes through the through hole and the universal rotating joint in sequence, and is threadedly connected to the universal rotating joint. The universal rotating joint is pushed to rotate and adjust the posture of the rotating rod 32 within the rotating groove, thereby changing the angle between the length direction of the rotating rod 32 and the length direction of the growth channel.

[0063] Under external force, the universal joint can rotate around the slot on its body. Since the rotating rod 32 passes through this universal joint, it adjusts its direction as the universal joint rotates. If the traction direction needs to be changed during orthodontic treatment, the pressure of the torsion spring must first be released, and then the position of the universal joint must be manually adjusted. Next, the rotating rod 32 is locked, allowing the entire system to re-accumulate the necessary elastic potential energy to effectively move the target tooth. To ensure that the rotating rod 32 remains in the correct position throughout the treatment, a universal joint made of a soft and elastic material, such as silicone, can be used. Compared to traditional hard alloys, this type of product is not only cheaper and easier to mass-produce, but also has a smooth surface that is less likely to cause irritation. The universal joint is installed into the corresponding groove through a tight fit. This increases the coefficient of friction between the two, reducing the risk of accidental movement due to external factors, thus ensuring that the tooth grows and develops along the expected path. Furthermore, this design allows for very fine adjustments to the angle, suitable for various complex situations.

[0064] Furthermore, refer to Figure 5 and Figure 6 The adjustment part 22 shown also includes a guide part 23. The guide part 23 includes at least two guide bars, one end of which is connected to the main body. At least two guide bars are arranged on opposite sides of the rotating rod 32 to guide the movement direction of the rotating rod 32.

[0065] During tooth growth and development, the changes in their growth direction are extremely subtle, necessitating a precise mechanism to ensure that orthodontic appliances apply force accurately. To this end, a guide 23 is provided, located on at least both sides of the rotating bar 32, and physically restricts the horizontal displacement of the bar, effectively preventing positional shifts caused by accidental collisions or patient movements. This not only improves the stability and safety of the entire system but also ensures that the force applied to the target area during treatment remains optimal. Furthermore, this design considers ease and flexibility in practical operation: for example, two parallel, adjustable-spaced guide rails can be used as a support frame; or a fully enclosed design, such as a cuboid shape, can be chosen, providing comprehensive protection and facilitating installation and disassembly. In short, regardless of the form, any solution that meets the basic functional requirements—preventing any factors that could lead to equipment failure—is a viable option.

[0066] Fifth Implementation Method

[0067] In the first and second embodiments, the oral appliance can expand the wound after cyst surgery to preserve sufficient space for tooth growth in the gums. However, under the action of the expansion support component 1, the wound will always remain open. But the patient needs to eat while waiting for the tooth to grow, and food residue is very likely to fall into the supported wound.

[0068] In view of this, the improvement of the fifth embodiment of this application compared with the first and second embodiments is that the oral appliance further includes a protective cover 5. The protective cover 5 matches the fixture 2 and is disposed on the fixture 2 to cover the growth channel. The protective cover 5 is provided with a tooth-mimicking surface to adapt to the tooth surface of the teeth on opposite sides in the oral cavity.

[0069] After the precise assembly of the oral speculum is completed, a protective cover is also included to maximize treatment effectiveness and improve the patient's quality of life. The protective cover not only fits perfectly onto the fixation frame 2 but also completely covers the surgical wound, greatly reducing the risk of external contaminants entering. More importantly, its surface is covered with a highly realistic artificial tooth enamel material, which not only improves the overall visual appearance but also significantly enhances wearing comfort. Furthermore, considering long-term durability and safety, the protective cover 5 is made of a new type of synthetic resin with good elastic recovery properties. This ensures stability even under the challenges of high-intensity daily activities.

[0070] Sixth Implementation Method

[0071] In the previous implementation, the oral cavity plug was placed in the wound by the fixing bracket 2, thus securing the plug. However, when the wound is tilted, securing the plug is more difficult.

[0072] In view of this, compared with the previous implementation method, refer to Figure 4 , Figure 7 and Figure 8 The improvement of the sixth embodiment of this application is that the oral appliance further includes a connecting component 4. The connecting component 4 is connected to the fixing frame 2, and the connecting component 4 has a mating hole 41 for fitting onto the teeth to install the fixing frame 2.

[0073] The connecting component 4 is tightly connected and fixed to the patient's teeth through a specially designed mating hole 41. The natural teeth are used as anchor points to restrict the component's movement, ensuring complete stability after installation. This stable connection method not only applies to the fixation frame 2 itself but also provides a solid foundation for the expansion support component 1, effectively supporting the wound area and ensuring optimal performance of the oral appliance.

[0074] Of particular note is that, to make this process more efficient and comfortable, refer to Figure 7 and Figure 8 The connecting component 4 shown can simultaneously accommodate multiple teeth. This allows each tooth involved in the fixation to play a crucial role, collectively sharing the external pressure and significantly enhancing the stability of the entire system. Furthermore, considering various potential problems in practical applications, the material should possess good biocompatibility, sufficient strength to withstand the stresses of daily chewing activities, and long-term durability; materials such as polymers and ceramics are also suitable. Moreover, since each patient's oral environment is different, the size of the connecting component 4, i.e., the number of teeth it accommodates, can be adjusted according to the patient's specific needs to accommodate different oral conditions.

[0075] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
