Description

Technical Field

[0001] This utility model relates to the field of orthodontic appliances, specifically a rapid arch expander for palatal micro-implant enhancement in patients with skeletal Class III maxillary dysplasia and crowding. Background Technology

[0002] Traditional treatment methods for patients with skeletal Class III maxillary dysplasia and crowding have many limitations. Specifically, the traditional rapid maxillary expander (RME), based on tooth support, easily leads to anterior movement and elongation of the maxillary molars, causing mesial movement of the maxillary dentition, labial tilting of the maxillary incisors, and increased crowding. For patients with decayed, loose, or lost deciduous molars, and whose permanent teeth have not yet erupted or have insufficient anchorage, the use of tooth-supported anterior traction may shorten the length of the maxillary dental arch, compressing the eruption space of subsequent permanent teeth and increasing the complexity of orthodontic treatment. In addition, traditional methods have limited effectiveness in improving maxillary hypoplasia and may cause adverse side effects such as tooth tilting and movement, affecting treatment efficiency and stability. Therefore, there is an urgent need for a new type of orthodontic appliance that can effectively solve the problem of maxillary dysplasia and crowding, while reducing adverse side effects and improving treatment efficiency and stability. Utility Model Content

[0003] The purpose of this invention is to provide a novel orthodontic appliance that can effectively solve the problem of maxillary hypoplasia with crowding, while reducing adverse side effects and improving treatment efficiency and stability.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rapid arch expander with palatal micro-implant enhancement, comprising:

[0005] The expander is fixed to the palate by micro-implants, and the middle part of the expander coincides with the midline of the teeth.

[0006] Two anterior braces, each clamped onto the first premolars on the left and right sides respectively;

[0007] Two front palatal bars connect the left anterior brace to the expander and the right anterior brace to the expander, respectively.

[0008] In some embodiments, the number of micro implants is four, which are respectively located at the four corners of the expander.

[0009] In some embodiments, four micro implants are symmetrically positioned in pairs on both sides of the midline of the palate.

[0010] In some embodiments, two palatal rods adapted to the curvature of the palatal wall are symmetrically arranged on both sides of the expander.

[0011] In some embodiments, both front braces are provided with traction hooks, and the traction hooks are connected to the front traction mechanism via rubber bands.

[0012] In some embodiments, a posterior clamp is provided on the first molars on both the left and right sides, and each anterior clamp is provided with two guide rods extending in the distal direction, and the guide rods movably pass through the posterior clamps, with a spring threaded on the guide rod located between the anterior and posterior clamps.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model effectively reduces the adverse side effects often caused by traditional rapid arch expansion techniques by implanting micro implants on the palatal side of the maxilla as bony anchorage.

[0015] 2. The expander fixed by the micro-implant can act more directly and effectively on the maxilla, maximize the opening of the palatal suture, promote the development of the maxilla, and improve treatment efficiency.

[0016] 3. The design of the middle part of the expander coinciding with the midline of the teeth ensures the accuracy and stability of the expansion, avoiding unnecessary deviation and shaking during the treatment process.

[0017] 4. For special cases such as patients with decayed, loose, or lost primary molars, this orthodontic appliance does not rely on tooth support and can better adapt to and avoid problems such as shortening of the maxillary dental arch length and compression of space for subsequent permanent tooth eruption.

[0018] 5. Through the symmetrical design of micro-implants, palatal bars, and traction hooks on the anterior braces, multi-dimensional orthodontic treatment of the maxilla and dentition is achieved, improving the precision and effectiveness of the treatment. Attached Figure Description

[0026] like Figure 1 As shown, this embodiment provides a rapid arch expander with palatal micro-implant enhancement, characterized in that it includes:

[0027] The expander 1 is fixed to the maxilla 200 by micro-implants 2. The middle part of the expander 1 coincides with the midline of the teeth. The micro-implants 2 serve as skeletal anchorage, providing a stable fixation point for the expander 1. Compared with traditional tooth support methods, this skeletal anchorage method can more effectively transmit the expansion force and reduce tooth movement and tilting. The expander 1 is the core component of the orthodontic appliance. It is fixed to the maxilla 200 by micro-implants 2, and the middle part of its separation point coincides with the midline of the teeth. This design ensures the accuracy and stability of the expander 1 during the expansion process, so that the expansion force can be applied evenly and effectively to the maxilla 100.

[0028] Two anterior braces 5 are respectively attached to the first premolars 300 on the left and right sides;

[0029] Two palatal bars 3 are connected between the left anterior brace 5 and the expander 1, and between the right anterior brace 5 and the expander 1, respectively. This connection method not only enhances the overall stability of the orthodontic appliance, but also allows the expansion force to be distributed more evenly on the maxilla 100, thereby achieving a more effective expansion effect.

[0030] During the orthodontic process, by adjusting the expansion force and speed of the expander 1, the palatal suture can be gradually opened, promoting the development and expansion of the maxilla 100. At the same time, the design of the anterior braces 5 and the palatal bar 3 can also perform certain orthodontic treatment and adjustment on the anterior teeth, thereby improving the crowding and malocclusion of the maxilla 100 dentition.

[0031] This type of orthodontic appliance effectively reduces the adverse side effects often caused by traditional rapid expansion techniques (such as RME), such as tooth tilting, forward movement and elongation of maxillary molars, mesial movement of the maxillary dentition, labial tilting of the upper incisors, and increased crowding, by implanting micro-implants 2 on the palatal side of the maxilla 100 as skeletal anchorage.

[0032] The micro-implant fixation expander 1 can act more directly and effectively on the maxilla 100, maximize the opening of the palatal midline, promote the development of the maxilla 100, and thus improve the efficiency of treating maxilla 100 dysplasia.

[0033] The design of the middle separation part of the expander 1 coinciding with the midline of the teeth ensures the accuracy and stability of the expansion, avoids unnecessary deviation and shaking during the treatment process, and further improves the stability of the treatment effect.

[0034] Furthermore, for patients with decayed, loose, or lost deciduous molars, whose permanent teeth have not yet erupted or whose anchorage is insufficient, this orthodontic appliance does not rely on tooth support, thus better adapting to these special circumstances and avoiding the problems of shortened maxillary arch length and compression of space for subsequent permanent tooth eruption.

[0035] In some embodiments, such as Figure 1 As shown, four micro-implants 2 are positioned at the four corners of the expander 1. Firstly, the four micro-implants 2 at the four corners of the expander 1 form a stable quadrilateral structure. This arrangement greatly enhances the fixation force and stability of the appliance on the maxilla 100. Compared to a smaller number of micro-implants 2, the four-implant design better distributes and absorbs the forces generated during expansion, reducing the risk of loosening or dislodging due to concentrated force, thus ensuring the continued effectiveness and safety of the appliance during treatment. Furthermore, the corner placement of the micro-implants 2 allows for more comprehensive coverage and action on key areas of the maxilla 100, particularly the mid-palatal suture and surrounding bone tissue. This comprehensive coverage enables the expansion force to be transmitted more evenly and effectively to all parts of the maxilla 100, promoting uniform opening of the mid-palatal suture and balanced development of the maxilla 100. This avoids the problems of local over-expansion or under-expansion that may occur in traditional expansion techniques, improving the precision and effectiveness of treatment.

[0036] Preferably, the four micro-implants 2 are symmetrically positioned in pairs on both sides of the midline of the maxilla 200. Firstly, this symmetrical arrangement ensures a balanced distribution of the micro-implants 2 on the maxilla 100. This balance not only enhances the overall stability of the appliance but also makes the transmission of the expansion force on the maxilla 100 more uniform and consistent. During the expansion process, the symmetrically positioned micro-implants 2 effectively counteract and disperse the torque and shear forces generated by the expansion force, reducing damage and adverse effects of the appliance on the maxilla 100 and surrounding tissues, thus improving the safety and comfort of the treatment. Secondly, the symmetrical design of the micro-implants 2 also helps to achieve precise control of the expansion force. By adjusting the distance and angle between the symmetrically positioned micro-implants 2, the magnitude and direction of the expansion force can be precisely controlled, thereby achieving fine-tuning of the development of the maxilla 100. This precise control not only improves the accuracy and effectiveness of the treatment but also reduces the risk of treatment failure or adverse side effects due to excessive or insufficient expansion force. Furthermore, the symmetrical placement of the micro-implants 2 helps adapt to the different morphology and development of the maxilla 100 in different patients. Because the morphology and development of the maxilla 100 vary between individuals, the symmetrical placement of the micro-implants 2 can be adjusted and optimized according to the specific patient's condition to ensure a close fit and effective action of the appliance to the maxilla 100. This adaptability not only improves the targetedness and effectiveness of treatment but also reduces the risk of treatment failure or adverse reactions due to mismatch between the appliance and the maxilla 100.

[0037] In some embodiments, such as Figure 1As shown, two posterior palatal bars 4 are symmetrically arranged on both sides of the expander 1, adapted to the curvature of the maxillary 200 wall. The design of these two posterior palatal bars 4 ensures, firstly, a close fit to the curvature of the maxillary 200 wall, guaranteeing comfort and stability during wear. Secondly, the symmetrical arrangement of the posterior palatal bars 4 further enhances the overall structural strength and stability of the orthodontic appliance. During expansion, the posterior palatal bars 4, together with the expander 1, the anterior palatal bars 3, and the anterior braces 5, form a stable mechanical system. This system effectively disperses and bears the expansion force, reducing the appliance's movement and displacement on the maxilla 100, thus ensuring the accuracy and effectiveness of the expansion. Furthermore, the design of the posterior palatal bars 4 also helps to achieve effective expansion of the posterior part of the maxilla 100. In traditional expansion techniques, because the expander 1 mainly acts on the anterior and middle parts of the maxilla 100, it may lead to insufficient or uneven expansion of the posterior part of the maxilla 100. The palatal bar 4 in this appliance can extend to the posterior part of the maxilla 100, so that the arch-expanding force can be more evenly distributed in all parts of the maxilla 100, achieving effective arch expansion and development promotion of the posterior part of the maxilla 100.

[0038] In some embodiments, such as Figure 1 As shown, both anterior braces 5 are equipped with traction hooks 6, which are connected to an external traction mechanism via elastic bands 7. Through the traction hooks 6, the appliance can be connected to the external traction mechanism, achieving multi-dimensional correction of the maxilla 100 and the dentition. This connection method not only enhances the efficiency of force transmission but also allows the dentist to flexibly adjust the treatment plan according to the patient's specific condition and treatment needs, thereby achieving better treatment results. The elastic band 7, as the medium connecting the traction hooks 6 and the traction mechanism, has good elasticity and adaptability. During treatment, the elastic band 7 can be appropriately stretched and adjusted according to the patient's intraoral environment and treatment needs, ensuring continuous and stable transmission of corrective force. At the same time, the soft material of the elastic band 7 reduces irritation and discomfort to the patient's oral tissues, improving the patient's wearing experience and treatment compliance. The traction mechanism, as an external auxiliary device for the appliance, further enhances the correction effect on the maxilla 100 and the dentition. By utilizing the anterior traction mechanism of the mask, forward traction and dentition rearrangement of the maxilla 100 can be achieved, thus more effectively improving the problem of maxillary 100 hypoplasia with crowding. This multi-dimensional orthodontic approach not only improves the efficiency and stability of treatment but also reduces the adverse side effects that may occur in traditional orthodontic methods.

[0039] In some embodiments, such as Figure 1-2As shown, posterior braces 9 are fitted onto the first molars 500 on both sides. Each anterior brace 5 has two guide bars 8 extending distally, which movably pass through the posterior braces 9. A spring 801 is threaded onto the guide bar 8 located between the anterior braces 5 and the posterior braces 9. When the appliance is worn in the patient's mouth, the spring 801 is compressed, thereby continuously applying a force that moves the anterior braces 5 and the posterior braces 9 away from each other. This force is effectively transmitted to the first premolars 300 and 500 through the guide bars 8, causing them to gradually separate and making enough space for the second premolar 400 located between them to grow. The purpose of this design is to use the continuous and gentle thrust generated by the spring 801 to cause the first premolars 300 and 500 on both sides to move away from each other, thereby solving the problem of limited growth space for the second premolar 400 caused by underdeveloped maxilla 100 with crowding.

[0040] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
