Description

Removable Dental Orthodontic Device {REMOVABLE ORTHODENTIC DEVICE}

The present invention relates to a removable orthodontic device comprising a straightening wire for straightening the teeth and a support portion formed inside the straightening wire for close contact with an oral band or soft palate in the oral cavity.

Types of devices used for orthodontics include fixed orthodontic devices, clear aligners and removable orthodontic devices. The fixed orthodontic device is a device that attaches the bracket to the tooth surface and inserts the orthodontic wire into the grooves carved into the piece to move the tooth with its elasticity. The transparent calibration device is a device that can proceed with the correction without damaging the aesthetics of the teeth by using a transparent plastic. The removable correction device is a device that the patient can wear and remove at will.

The orthodontic device worn from the outside of the orthodontic device using the fixed orthodontic device is a bracket that is slightly corroded to the surface of the tooth attached with a strong adhesive, and the wire used to fix and pull the suspension to the bracket, and the bracket Or a support member capable of transmitting a force to the wire, a spring, and a tooth band or alveolar bone screw to serve as a fixing part of the wire and the support member. Brackets and wires are installed on the exposed part of the teeth, which places a lot of restrictions on the external activities of orthodontic patients.

As an alternative to this fixed orthodontic device, the removable orthodontic device can be worn and removed by the patient at will. In general, children are mainly used to solve problems such as simple orthodontics and space securing before replacing all teeth with permanent teeth, and do not attach orthodontic devices to the teeth. Can be removable. It can also be used by adults. Since the patient can be freely detached, great care is required, and it must be worn as long as possible to see the effect.

The removable device can be divided into two types.

The first is a device used to achieve skeletal changes, ie to change the shape of the bone, which in this case is usually a mass up and down, which is held in the mouth. Usually used for growing children, it is used for the treatment of the large jaw skeleton or the lower jaw skeleton. In addition, removable devices are also used to maintain post-treatment conditions after orthodontic treatment.

The second is a device used for the movement of teeth like a stationary orthodontic device, and the device for movement of teeth is usually inserted one side up or down. This conventional removable device is shown in FIG. 1. As shown in FIG. 1, a conventional removable device includes a straightener 10 having a wire and a straightener for straightening teeth and a support 20 formed inside the straightened portion 10.

However, these conventional removable orthodontic devices do not have the same effect as fixed orthodontic devices that move teeth one by one, and it is difficult to achieve a satisfactory effect with the removable device alone instead of the fixed device in the treatment of all malocclusions. This is different from the orthodontic device and its working principle, it is difficult to use the sophisticated orthodontic treatment simply by moving the tooth. Therefore, it was generally limited to only partially moving the teeth by moving them, or it was generally used to only maintain the corrected teeth after the teeth were corrected by the fixed orthodontic device.

The present invention aims to provide a new concept removable correction apparatus that can effectively treat malocclusion by adding and supplementing the advantages of the conventional fixed correction apparatus to the conventional removable correction device.
