TECHNICAL FIELD
[0001] The utility model relates to medical appliance technical field, specifically point to a kind of auxiliary tooth movement traction orthodontic device. BACKGROUND
[0002] The main purpose of orthodontic treatment is to induce tooth movement in alveolar bone by applying continuous light force, so as to achieve the purpose of correcting tooth arrangement and improving occlusal relationship. Traditional orthodontic methods mainly rely on fixed devices such as brackets and arch wires to achieve tooth movement, but these methods have limitations in some cases, for example:
[0003] Insufficient anchorage control: In cases requiring large tooth movement or complex movement, traditional methods are difficult to provide sufficient anchorage force, which can lead to loss of anchorage and affect treatment results.
[0004] Limited control of tooth movement: Traditional methods have relatively limited control over the direction and intensity of tooth movement, making it difficult to achieve fine control of tooth movement.
[0005] Patient comfort issues: Traditional brackets and arch wire devices are large in size and can cause friction and irritation to oral mucosa, leading to discomfort and even oral ulceration in patients.
[0006] To solve the problem of insufficient anchorage control in traditional orthodontic methods, anchorage pins (also known as micro-screw implants) are introduced into orthodontic treatment. Anchorage pins are implanted into alveolar bone to provide stable anchorage force for tooth movement, effectively solving the problem of loss of anchorage.
[0007] At the same time, to achieve fine control of tooth movement direction and intensity, traction hooks and springs are widely used in orthodontic treatment. Traction hooks are connected to brackets or anchorage pins and use the elastic force of springs to apply continuous traction force to teeth, thereby achieving tooth movement.
[0008] Although the use of anchorage pins, traction hooks and springs has greatly improved the effectiveness of orthodontic treatment, there are still some limitations in existing technology:
[0009] Complex structure, inconvenient operation: Some existing traction hook devices have complex structure, and the installation and adjustment process is cumbersome, increasing the workload and difficulty of doctors.
[0010] Insufficient comfort: Some traction hook devices are not designed humanely enough, which can cause friction and irritation to oral mucosa, affecting the wearing comfort of patients.
[0011] Adjustment is not convenient: Some devices have limited adjustment function, and it is difficult to make fine adjustments according to the specific situation of patients, affecting the treatment effect.
[0012] Therefore, an auxiliary tooth movement traction orthodontic device is provided to solve the existing problems. Utility model content

[0014] To solve the above technical problems, the utility model provides a technical scheme of an auxiliary tooth movement traction orthodontic device: including a bracket, a traction hook and a anchorage nail.
[0015] The bracket can be detachably bonded to the surface of a dental crown, and a plurality of brackets located on different dental crowns are connected through an arch wire arranged transversely.
[0016] The traction hook is inserted into the bracket, the traction hook includes a plug rod inserted into the bracket and a H-shaped hook body arranged horizontally at the top end of the plug rod, an adjusting rod is inserted into the bracket to be treated, a strip-shaped connecting ring arranged horizontally at the top end of the adjusting rod, the anchorage nail is connected to one end of the strip-shaped connecting ring through a rubber band, and the hook body is connected to the other end of the strip-shaped connecting ring through a tension spring.
[0017] As an improvement, the hook body and the strip-shaped connecting ring are arranged flush.
