Description

Technical Field

[0001] This application belongs to the field of orthodontic appliance technology, specifically a deformity corrector. Background Technology

[0002] Orthodontic appliances are common dental correction devices. These regularly shaped appliances are fitted onto the user's teeth and continuously apply force to correct their alignment. In recent years, dental malocclusion in children has become increasingly serious, leading to a growing demand for orthodontic treatment. Dental malocclusion is often accompanied by poor oral habits such as mouth breathing, abnormal swallowing, and tongue misalignment. During treatment, as the malocclusion gradually corrects itself, parts of the original appliance may no longer provide the necessary corrective force.

[0003] For example, CN219306977U discloses a dental appliance, relating to the field of orthodontic appliance technology. This dental appliance includes a dental shell with a cavity for accommodating teeth. Space blocks are provided on the front and rear inner walls of the cavity. The space blocks are grouped in sets of four, with each group consisting of two front and two rear space blocks fixed to the inner wall of the cavity, forming a dental groove. This dental appliance refills the filling material according to the angle required during the second stage of treatment, allowing the orthodontic attachments to change according to the angle needed for the second stage. Therefore, it allows for continuous orthodontic treatment without replacing the dental shell, reducing costs during treatment. It also makes angle adjustment of the orthodontic attachments more convenient and quick, shortening manufacturing time and eliminating waiting time for the wearer during the customization process, thus preventing tooth relapse.

[0004] However, in this application, the shape of the orthodontic appliance is fixed and cannot be adjusted according to the patient's orthodontic progress, which greatly increases the complexity of orthodontic treatment. Utility Model Content

[0005] The purpose of this application is to provide a malocclusion correction appliance to solve the aforementioned problem of tooth shell adjustment.

[0006] The technical solution adopted in this application is as follows: A malocclusion correction appliance includes a dental shell, two fixed threaded blocks are fixedly provided at both ends of the dental shell on the side surface opposite to the oral cavity, and the internal threads of the two fixed threaded blocks are connected to a threaded rod one and a threaded rod two, and the surfaces of the threaded rod one and the threaded rod two are threadedly connected to a threaded cylinder, and the surface of the threaded cylinder is provided with anti-slip texture.

[0007] By adopting the above technical solution, when the dental shell needs to be adjusted according to the patient's orthodontic treatment, threaded rod one and threaded rod two can be threaded together with two fixed threaded blocks on the surface of the dental shell. Then, the doctor can pinch the anti-slip texture on the surface of the threaded cylinder with his fingers and rotate the threaded cylinder to make threaded rod one and threaded rod two move in and out, thereby changing the overall shape of the dental shell. This allows the component structure to adjust the dental shell according to the progress of the patient's orthodontic treatment, and the anti-slip texture can play a certain anti-slip role.

[0008] In a preferred embodiment, a tongue guard is fixedly provided on one side of the tooth shell inside the oral cavity, and the tongue guard is made of medical rubber.

[0009] By adopting the above technical solution, the tongue guard can provide a certain degree of protection for the tongue.

[0010] In a preferred embodiment, the surface of the tooth shell is provided with a tooth groove, and the surface of the tooth groove is provided with a disassembly film.

[0011] By adopting the above technical solution, the alveolar joint with the disassembly membrane set on the surface of the tooth shell can make the structure fit on the patient's tooth surface, while playing a role in correction and protection.

[0012] In a preferred embodiment, the surface of the disassembly membrane is provided with a plurality of gap blocks corresponding to the teeth.

[0013] By adopting the above technical solution, the multiple gap blocks can serve as interdental spaces.

[0014] In a preferred embodiment, the inside of the tooth shell is provided with a reinforcing elastic piece one and a reinforcing elastic piece two on both sides of the alveolar bone.

[0015] By adopting the above technical solution, the tooth shell can be provided with strong plasticity by setting reinforcing elastic sheet one and reinforcing elastic sheet two inside the tooth shell, and at the same time, it is easy to adjust the shape of the structure.

[0016] In a preferred embodiment, a plurality of fixing blocks are provided on one side surface of the tooth shell, and fixing brackets are provided on the surface of the fixing blocks, and fixing cylinders are provided on the surfaces of the two fixing blocks at the ends of the tooth shell.

[0017] By adopting the above technical solution, the fixed block facilitates the fixed cylinder and fixed bracket to be fixedly installed on the surface of the tooth shell. At the same time, the fixed cylinder can play a role in limiting and protecting, while the fixed bracket can play a role in lifting.

[0018] In a preferred embodiment, the interior of the fixing cylinder and the fixing bracket is provided with an elastic bow wire.

[0019] By adopting the above technical solution, the fixed cylinder and fixed bracket facilitate the placement of the flexible archwire. The flexible archwire can be easily adjusted and replaced by the dentist according to the patient's orthodontic condition, enabling the device to provide further orthodontic treatment.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, when the dental shell needs to be adjusted according to the patient's orthodontic treatment, threaded rod one and threaded rod two can be threaded together with two fixed threaded blocks on the surface of the dental shell. Then, the doctor can pinch the anti-slip texture on the surface of the threaded cylinder with his fingers and rotate the threaded cylinder to make threaded rod one and threaded rod two move in and out, thereby changing the overall shape of the dental shell. This allows the component structure to adjust the dental shell according to the progress of the patient's orthodontic treatment, and the anti-slip texture can play a certain anti-slip role.
