Description

Technical Field

[0001] The present invention relates to the field of oral orthodontics, and in particular to a micro-implant-assisted body intrusion appliance (MABIA) and a corresponding correction method, aiming to achieve vertical intrusion of teeth and multi-directional correction force control through stable anchorage. Background Art

[0002] In modern orthodontic treatment, vertical intrusion of teeth is widely used in the treatment of maxillary molars. However, maxillary molars are anatomically located posteriorly and have complex structures, making it challenging to achieve precise force application, especially when ensuring stable support and precise control of the direction and magnitude of force. The difficulty of treatment is further increased. Traditional tooth intrusion methods usually rely on adjacent teeth to provide support, or apply corrective force through external devices such as head caps and face bows. However, these methods have many limitations, resulting in less than ideal clinical application results.

[0003] First of all, traditional adjacent teeth support often causes uneven force problems. When adjacent teeth are used as support, the force transmission between the teeth is easily unbalanced, resulting in unexpected movement of the support teeth, and even adverse reactions, which undermine the expected effect of the treatment. The force application method using adjacent teeth as support is very easy to produce deviations during the force transmission process, which is not only difficult to achieve the desired vertical depression effect, but may also cause side effects of the support teeth. Especially for the depression treatment of maxillary molars, due to the stability of the adjacent teeth support, traditional methods often result in unsatisfactory depression effects due to insufficient support force.

[0004] Secondly, external devices also have significant defects in force accuracy and patient compliance. External support devices such as head caps and face bows provide support by fixing the head, but such devices are inconvenient to wear and have poor compliance, especially in adult patients. In addition, the force direction of these external devices is usually difficult to control accurately and is limited by the patient's anatomical structure. Because the external support method of the device is not sophisticated enough, problems such as patient discomfort and inconvenient operation often occur in clinical applications, which greatly reduces the patient's treatment compliance and makes it difficult to achieve the ideal vertical depression effect.

[0005] With the introduction of micro-implants in orthodontic treatment, the stability problem of anchorage has been solved to a certain extent. Micro-implants are small devices that are directly implanted into the alveolar bone. They have high anchorage stability and are easy to implant and remove. Micro-implants have achieved good results in assisting tooth adduction and arch expansion, and are gradually being used in the field of orthodontic anchorage. However, there are still some shortcomings in the current application of micro-implants, especially in areas where the alveolar bone volume is insufficient at the required implantation site. Stability cannot be guaranteed, and thus the proper anchorage function cannot be exerted, making it difficult to fully meet the needs of orthodontic treatment. Therefore, how to ensure the stability of micro-implants and, on this basis, achieve precise control of the direction and magnitude of force is an urgent problem to be solved in the current field of orthodontic anchorage technology.

[0006] In summary, the existing technology mainly has the following problems:

[0007] 1. Insufficient support stability: The traditional support method of adjacent teeth leads to uneven force, which can easily cause unexpected movement of the support teeth and even cause adverse reactions. Although external devices (such as headgear and face bow) provide support, they are inconvenient to wear, especially in adult patients, where compliance is poor. In addition, the external support device has poor fixation and poor support stability, resulting in unstable correction effect.

[0008] 2. Imprecise force control and uneven force application: Existing methods of depression (such as elastic traction, etc.) are not precise enough in controlling the magnitude and direction of force, and are easily affected by the patient's anatomical structure, resulting in unstable depression effects. At the same time, the multi-point force application in traditional methods can easily cause force dispersion or concentration, increase the stress load on periodontal tissues, easily cause discomfort to patients and affect the health of periodontal tissues, thereby reducing the correction effect and patient comfort.

[0009] 3. Limitations of multi-directional correction force: Traditional orthodontic appliances are difficult to apply force in both vertical and horizontal directions, which limits the flexibility and effect of correction. Existing correction methods are usually only suitable for force control in a single direction and cannot adapt to complex orthodontic needs, especially in terms of flexible application of multi-directional force.

[0010] 4. Poor patient compliance: Traditional external support devices have low compliance, are inconvenient to wear, and are complicated to use, which can easily cause discomfort to patients. Adult patients, in particular, have obvious compliance issues when wearing external devices, which in turn affects the treatment effect. At the same time, the discomfort caused by traditional devices is relatively large, which further reduces the patient's compliance.

[0011] 5. High operational complexity: Although the method of combining micro-implants with traditional correction devices improves the function of support, when faced with insufficient bone volume at the required implant site, doctors need to spend more time adjusting the implant site in clinical applications. When the implant site is relatively limited, it is difficult to apply force, which is not conducive to simple and rapid promotion and application. Summary of the invention

[0036] <First Preferred Embodiment>

[0037] Figure 1A and Figure 1B A schematic diagram of a micro-implant support overall depression appliance according to a preferred embodiment of the present invention is shown schematically, and a photo of the installation state of the specific object is shown in FIG. Figure 2 Specifically, the micro-implant-supported integral intrusion appliance is used to achieve vertical (and further mesiodistal) movement of teeth during orthodontic procedures.

[0038] like Figure 1A and Figure 1B As shown, the micro-implant support integral depression appliance according to a preferred embodiment of the present invention includes: a fixing component 10, a telescopic component 20 and a belt ring 30.

[0039] The fixing component 10 is used to be fixed to the maxillary bone of the oral cavity, providing a stable support base to ensure that the device remains stable during the correction process.

[0040] The telescopic component 20 has a telescopic function in a single direction and is fixedly connected to the fixed component 10. It provides an outward thrust or an inward pull by adjusting its length, thereby applying the required correction force. For example, the doctor can adjust the length of the telescopic component according to the correction requirements to provide an appropriate correction force. For example, Figure 1A and Figure 1BThe telescopic member 20 shown is a telescopic member having a telescopic function in a single vertical direction.

[0041] The band ring 30 is fixedly connected to the telescopic component 20 and is used to be looped on the target tooth (preferably the band ring 30 is further fixed on the tooth by an adhesive), so as to directly transmit the correction force applied by the telescopic component 20 to the target tooth. Preferably, the band ring 30 is connected to the telescopic component through a connecting rod and is the direct transmission end of the correction force.

[0042] Preferably, the connection portion between the telescopic component 20 and the fixed component 10 and the connection portion between the telescopic component 20 and the belt ring 30 can be adjusted in angle to achieve fine adjustment of the direction of the given correction force.

[0043] For example, the morphological design of the connection between the telescopic component 20 and the fixed component 10 and the connection between the telescopic component 20 and the belt ring 30 allows the direction to be adjusted within a limited range, so as to adapt to the anatomical morphology of the patient's oral cavity and fine-tune the force application angle according to treatment needs. Moreover, preferably, the direction adjustment of the connection between the telescopic component 20 and the fixed component 10 and the connection between the telescopic component 20 and the belt ring 30 ensures that the force transmission path is accurate and avoids mechanical deviation caused by angle deviation.

[0044] Preferably, if Figure 1A and Figure 1B As shown, the micro-implant support overall depression appliance according to the preferred embodiment of the present invention further includes: an implant nail 40, which is implanted into the maxillary bone through the implant hole on the fixing component to firmly fix the appliance.

[0045] The micro-implant-based integral depression appliance according to the preferred embodiment of the present invention can provide more stable support and more accurate multi-directional correction force control to meet the complex depression requirements in orthodontic treatment. The micro-implant-supported integral depression appliance according to the preferred embodiment of the present invention ensures the stability and accuracy of the correction force through an integrated design. Specifically, the integrated design of the MABIA device achieves the following technical effects:

[0046] Improved anchorage stability: Micro-implants provide a stable anchorage point, avoiding the instability of adjacent tooth anchorage and improving the stability of the correction effect.

[0047] Multi-directional correction force control: The force can be applied in multiple directions and precisely controlled through telescopic parts and connecting parts, and the direction and magnitude of the force can be adjusted according to the patient's needs.

[0048] ·Easy to operate: MABIA's integrated structural design simplifies the operation process, makes it easy to promote and apply in clinical practice, and improves the convenience of orthodontic treatment.

[0049] <Second Preferred Embodiment>

[0050] Figure 3A and Figure 3B A schematic diagram of a micro-implant support overall depression appliance according to another preferred embodiment of the present invention is schematically shown, and a photo of the installation state of the specific object is shown in FIG. Figure 3A and Figure 3B shown.

[0051] Figure 3A and Figure 3B The preferred embodiment shown is Figure 1A and Figure 1B The preferred embodiment shown differs in that: Figure 1A and Figure 1B The preferred embodiment shown only includes a telescopic member 20 having a telescopic function in a single direction of proximal and distal directions; Figure 3A and Figure 3B The preferred embodiment shown includes not only a telescopic component having a telescopic function in a single vertical direction, but also a telescopic component having a telescopic function in a single proximal and distal direction.

[0052] Specifically, Figure 3A and Figure 3B As shown, the micro-implant support overall depression appliance according to a preferred embodiment of the present invention includes: a fixing component 10, a first telescopic component 21, a second telescopic component 22, and a first belt ring 31 and a second belt ring 32.

[0053] The fixing component 10 is used to be implanted into the maxillary bone through the implant screw 40 to provide a stable support base and ensure that the device remains stable during the correction process.

[0054] The first telescopic component 21 has a telescopic function in a single vertical direction and is fixedly connected to the fixed component 10, and the second telescopic component 22 has a telescopic function in a single mesiodistal direction and is fixedly connected to the first telescopic component 21; moreover, the first telescopic component 21 and the second telescopic component 22 provide outward thrust or inward pulling force by adjusting their lengths, thereby working together to apply the required corrective force.

[0055] The first band ring 31 is fixedly connected to the first telescopic component 21 and is used to be looped over the target tooth, so as to directly transmit the vertical correction force to the target tooth.

[0056] The second band ring 32 is fixedly connected to the second telescopic component 22, and is used to be looped over the target tooth, so as to directly transmit the vertical and horizontal correction forces to the target tooth.

[0057] Preferably, one end of the first telescopic component 21 is connected to the fixing component 10 , and the other end of the first telescopic component 21 is connected to the second telescopic component 22 .

[0058] <Design Example>

[0059] 1) Fixation component design: The fixation component is the core support part of the MAB IA device, which is designed to firmly implant the device into the maxillary bone. The component is provided with several implantation holes to ensure that the implant pins can be firmly implanted to provide stable support for the entire device. The design structure of the fixation component takes into account the stability of support and the flexibility of implantation angle, so that it can adapt to the maxillary anatomical characteristics of different patients and ensure the stable transmission of correction force.

[0060] 2) Design of telescopic components: The telescopic components have a unidirectional telescopic function, and the length can be adjusted manually to achieve outward thrust or inward pulling force to provide the appropriate correction force. The main function of the telescopic component is to control the strength of the force by extending or contracting the frequency without changing the direction of the force. It is used in conjunction with the connecting component to accurately adjust the force during the treatment process. Since the component only works in one dimension, the structure is simple but the force is stable, which effectively reduces the complexity of the operation.

[0061] 3) Connection component design and angle fine-tuning: The connection component is used to connect the telescopic component to the fixed component and the ring part. Its design allows for fine-tuning of the direction within a limited range to adapt to the patient's oral anatomy and ensure accurate force transmission. The connection component can be designed to finely adjust the direction and angle to ensure that the direction of the telescopic component's force matches the movement requirements of the teeth. This fine-tuning function ensures the flexibility of the force angle, avoids correction errors caused by the direction of the fixed force, and thus achieves a personalized treatment plan.

[0062] 4) Band design: The band is designed to be placed on the target tooth and fixed with adhesive to ensure direct transmission of the correction force. The band is connected to the telescopic component through a connecting rod, which can directly and effectively transmit the force applied by the telescopic component to the target tooth. The shape of the band is designed to adapt to the structure of the tooth, ensuring that it can be fixed while reducing discomfort to the periodontal tissue. Through the band, the correction force can be accurately applied to the target tooth to achieve the ideal depression or movement effect.

[0063] 5) Implant design and implantation: The implant is implanted into the maxillary bone through the implant hole on the fixed component, providing a stable anchor point for the entire MABIA device. The implant is made of metal with good biocompatibility and strong compressive and tensile strength to ensure that it will not loosen during the force application process. The stability of the implant is crucial to the overall anchor effect of the MABIA device, so that the device remains stable when the correction force is applied.

[0064] It should be noted that the component design and functional combination of the device are the key technical features of the present invention, and its manufacturing method (such as 3D printing or factory lathe processing) does not affect the function and technical protection scope of the device.

[0065] <Example of usage>

[0066] The first step is to perform oral 3D modeling and device design: Before starting treatment, the doctor needs to generate accurate 3D data based on the patient's oral 3D modeling (such as through CBCT or other imaging technology). This data will be used to design the MAB IA device to ensure that each component of the device accurately matches the patient's oral structure.

[0067] The second step is to fabricate the MAB IA device: Based on the 3D modeling results, a personalized MAB IA device can be fabricated by 3D printing or lathe processing. Regardless of the fabrication method, the device must meet the design specifications to ensure mechanical stability and correction effect after installation.

[0068] The third step is to install the device and adhere the band: After applying adhesive to the band in the patient's mouth, fit the band portion of the MAB IA device to the target tooth, ensuring that the band adheres firmly after the adhesive cures. The band needs to be accurately positioned during the fitting process to ensure that the adhesive can provide reliable fixation after curing.

[0069] The fourth step is to perform implantation: implant the implant into the patient's maxillary bone through the implant hole on the fixed component to provide a stable support base for the device. This process needs to be performed accurately according to the patient's bone density and implantation angle to ensure the stability of the device when the correction force is applied. The stable implantation of the implant ensures that the entire device will not be displaced due to the force.

[0070] The fifth step is to adjust the telescopic component and apply the correction force: by adjusting the length of the telescopic component, the doctor can gradually apply the required correction force. The telescopic component provides force in one dimension, and the thrust or pull can be controlled by adjusting the telescopic length. The connecting component is designed according to the treatment requirements at the beginning of the design to ensure that the force application angle meets the movement requirements of the teeth. During the entire correction process, the doctor can adjust the length of the telescopic component at any time to achieve precise control of the force intensity.

[0071] Step 6: Treatment monitoring and mechanical parameter adjustment: During the treatment process, the doctor needs to regularly monitor the movement of the teeth and adjust the mechanical parameters of the MAB IA device in a timely manner according to the patient's actual response. This adjustment includes fine-tuning the length of the telescopic component and resetting the direction of the connecting component to ensure that the correction force is always adapted to the movement requirements of the teeth, thereby achieving the best treatment effect.

[0072] <Technical Effects>

[0073] Through the above structural design and use method, the MABIA device of the present invention achieves the following technical effects:

[0074] Improved anchorage stability: Micro-implants provide highly stable anchorage points, avoiding the problems of uneven force and anchorage loss caused by traditional adjacent tooth anchorage.

[0075] · Accurate correction force control: Through the one-way adjustment function of the telescopic component and the fine adjustment of the direction of the connecting component, the present invention can accurately apply appropriate force in the vertical direction and / or the mesiodistal direction to meet complex orthodontic needs.

[0076] Easy and personalized installation: The integrated structural design of the MABIA device simplifies the installation process, and the length adjustment of the telescopic parts can adapt to the needs of different patients, thereby improving the personalization and convenience of orthodontic treatment.

[0077] Improved patient comfort and compliance: Compared with traditional correction methods, the MABIA device reduces discomfort and operation complexity through precise force control and stable support, significantly improving patient comfort and compliance, and is particularly suitable for orthodontic treatment of adult patients.

[0078] <First Implementation Example: Vertical Intrusion of Maxillary Molars>

[0079] like Figure 2 As shown in the figure, the orthodontic target position of the patient requires the posterior teeth (teeth 5, 6, and 7) to be depressed (moved gingivally) to optimize the occlusion and improve the facial shape. Traditional dental anchorage cannot provide a depression force, and the conventional implantation site of the implant anchorage nail, i.e., the buccal and palatal alveolar bone of the posterior teeth, cannot be implanted because the patient's maxillary sinus floor is too low and the sinus cavity is too large to provide sufficient bone support, affecting the stability of the anchorage nail. The micro-implant anchorage overall depression appliance (MAB IA) of the present invention can accurately apply a vertical depression force while maintaining the stability of the anchorage to achieve an ideal orthodontic effect.

[0080] Steps:

[0081] 1. Device design and 3D modeling: Based on the patient's CBCT 3D scan results, obtain an accurate model of the oral structure and determine the position and angle of the target molar. Design the MABIA device based on the 3D model to ensure that its shape and size match the patient's anatomy. The main components of the MABIA device include implants, fixation components, telescopic components, connection components, and bands. The colors in the figure are:

[0082] 2. Device installation and band adhesion: Place the MABIA device in the patient's mouth, make the band close to the target molar, and evenly apply adhesive on the inside of the band to ensure that the band is firmly adhered to the target tooth. This step ensures that the correction force can be effectively transmitted to the target tooth.

[0083] 3. Implantation of implant screws and installation of fixing components: Use the blue implant screws in the figure to firmly implant the implant screws into the maxillary bone through the reserved holes on the fixing components to form the anchorage point of the MAB IA device. This anchorage point can withstand the vertical compression force applied during the correction process to ensure the stability of the device.

[0084] 4. Adjustment of telescopic components and application of vertical force: By adjusting the length of the telescopic component (light blue part), an appropriate inward pulling force is applied to achieve the vertical depression effect of the target tooth. The one-way adjustment function of the telescopic component ensures the stability and accuracy of the correction force, so that the target tooth can be gradually moved to the ideal position in the vertical direction.

[0085] 5. Observation and adjustment: During the treatment process, the doctor regularly observes the movement of the patient's teeth and fine-tunes the length of the telescopic component according to the actual effect to ensure that the direction and magnitude of the force meet the treatment needs. This operation can maintain the stability of tooth movement and ensure the final correction effect.

[0086] Treatment effect: By using the MAB IA device, the patient's target teeth achieved the expected vertical intrusion effect and restored the normal occlusal relationship while ensuring the stability of the anchorage. The force direction during the entire treatment process was accurate and the anchorage was stable. The patient felt comfortable during the treatment and had high compliance.

[0087] <Second implementation example: combined correction of vertical intrusion and mesiodistal translation of maxillary molars>

[0088] like Figure 4 As shown, the patient's orthodontic target position requires the molars to be depressed and moved distally to optimize the occlusion and improve the facial shape. Traditional orthodontic devices lack multi-directional control capabilities and are difficult to meet the combined needs of vertical overall depression and mesiodistal translation. The micro-implant-supported overall depression appliance (MAB IA) of the present invention can effectively meet this complex orthodontic need. Through two telescopic components, correction forces in both vertical and mesiodistal directions can be applied simultaneously, thereby achieving a complex combined correction effect.

[0089] Procedure

[0090] 1. 3D modeling and personalized design: First, the precise anatomical data of the patient's oral cavity is obtained through CBCT 3D scanning, and the MABIA device suitable for this case is designed. The design and production of the device ensure that each component can accurately transmit the expected force. The main components of the MABIA device include:

[0091] 2. Device installation and band fixation: Install the band part on the target molar surface and apply adhesive to fix it so that the band adheres firmly to the target tooth. The precise fit after band fixation allows the correction force to act stably and directly on the target tooth, ensuring the effectiveness of the force.

[0092] 3. Implantation of implant screws and stabilization of the device: The blue implant screws are implanted into the maxillary bone through the preset holes of the fixing components. The installation of the implant screws provides a stable support to ensure that the entire device will not shift when the correction force is applied. The installation angle of the implant screws is precisely designed to meet the support requirements of this case.

[0093] 4. Adjustment and force application of the telescopic component 1 in the vertical direction: The telescopic component 1 in the vertical direction is specifically used to provide vertical depressing force. The doctor gradually applies inward pulling force by adjusting its length, so that the target tooth is gradually depressed in the vertical direction. The one-way telescopic function of this component ensures the stability and continuity of force application, effectively controls the magnitude of the vertical force, and avoids unnecessary horizontal displacement.

[0094] 5. Adjustment and force application of the mesiodistal telescopic component 2: The mesiodistal telescopic component 2 is used to apply mesiodistal translational force. By adjusting the length of the telescopic component 2, the doctor can translate the target tooth to the predetermined mesiodistal direction. The design of the telescopic component 2 ensures the accuracy of the mesiodistal translational force without interfering with the vertical depression, thereby achieving independent control of multi-directional forces.

[0095] 6. Regular observation and mechanical parameter adjustment: During the entire correction process, the doctor needs to regularly check the movement of the teeth and adjust the length of telescopic parts 1 and 2 according to the patient's actual response to ensure that the magnitude and direction of the correction force meet the treatment needs. This real-time adjustment ensures the flexibility and accuracy of the treatment, allowing the patient's teeth to gradually reach the ideal position according to the design plan.

[0096] Treatment effect: Through the synergistic effect of the two telescopic parts, the MABIA device of the present invention successfully achieves the correction needs of maxillary molars in vertical and mesiodistal directions. The independent control of vertical and mesiodistal forces ensures the high efficiency and accuracy of the treatment. The patients feel comfortable and have high compliance during the entire treatment process, and finally achieve the ideal treatment effect.

[0097] <Technical advantages>

[0098] The technical advantages of the present invention include at least the following aspects:

[0099] 1. Stable micro-implant support: The implantation of micro-implants provides a stable support foundation, which can avoid the problem of uneven force transmission caused by adjacent tooth support, and overcome the problem of poor compliance of external support devices. The high-stability support design of micro-implants is suitable for complex orthodontic mechanical requirements, especially in the vertical intrusion treatment of maxillary molars.

[0100] 2. Multi-directional force adjustment of telescopic components: The telescopic structure design of the MAB IA device allows doctors to flexibly adjust the angle and size of force in the vertical and horizontal directions according to treatment needs. By accurately adjusting the length of the telescope, the MAB IA device can achieve vertical depression of the target teeth while flexibly responding to complex orthodontic needs in multiple directions such as mesiodistal movement, thereby meeting the personalized treatment needs of different patients.

[0101] 3. Improve patient comfort: Traditional orthodontic appliance designs often have the problem of excessive stress on periodontal tissues caused by multiple points of force application. The MAB IA device of the present invention can effectively disperse the points of force application and reduce the stress load on periodontal tissues through stable support and precise force application design, thereby significantly improving patient comfort. The MAB IA device is simple and easy to operate, and the installation process is convenient and quick, which is convenient for patients to wear daily, and can also reduce the problem of decreased compliance caused by discomfort.

[0102] In summary, the MAB IA device of the present invention provides a multifunctional, high-precision orthodontic anchorage solution, which provides stable anchorage through micro-implants and combines a multi-directional telescopic structure to achieve precise adjustment of mechanical control, thus overcoming the mechanical defects of traditional anchorage methods.
