Problems solved by technology

When using invisible aligners to depress the canines, the depressing effect is often not ideal due to the thick roots of the canines
If the depression of the canines does not reach the designed amount, the appliance will form a fulcrum at the canines, resulting in the inability of the adjacent teeth to be fully seated, and the appliance will not be able to fully wrap the teeth, resulting in de-coupling, and the designed tooth movement will be more difficult to achieve

Embodiment Construction

[0015] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] see Figure 1-3 , a device for assisting in depressing canines in the invisible orthodontic process, comprising an appliance 1, a retaining nail hole 2 and a premolar occlusal device 3 are arranged on the appliance 1; the cylinder at the lower end of the premolar occlusal device 3 is fixed In retainer hole 2.

[0017] The appliance 1 is a conventional invisible aligner.

[0018] There is at least one retaining nail hole 2 running through the occlusal surface of the premolar area of ​​the appliance, and the diameter of the retaining nail hole is 1.0-2.0 mm.

[0019] The premolar occlusal pad device 3 is located on the occlusal surface of the appliance 1, and is used to raise the occlusal device of the teeth. The devices are all included in the scope of protection of this patent, and are tightly fixed ...

Abstract

A device for assisting in lowering canine teeth in the invisible correction process comprises a correction device, and a retention nail hole and a premolar occlusal pad device are arranged on the correction device. The column body at the lower end of the premolar occlusal pad device is fixed in the retention nail hole, so that premolar teeth form an occlusal heavy contact area to resist the extension trend of the premolar teeth, and the aim of assisting the invisible orthodontic appliance in depressing canine teeth is fulfilled; the pair of glasses has the characteristics of convenience in operation, practicability, high efficiency, comfort in wearing and strong retention force.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and in particular relates to a device for assisting canine depression in the process of invisible orthodontics. Background technique [0002] Bracketless clear aligners are favored by patients because of their aesthetics and comfort, and are increasingly used in orthodontics. However, due to the limitation of the material of the clear aligner without brackets, there is a "hysteresis" in tooth movement, that is, the movement of the teeth cannot keep up with the shape change of the clear aligner without brackets, and the preset amount of tooth movement cannot be fully realized. Prolong the treatment time and reduce the efficiency. Especially for elongation and depression movements, studies have shown that the depression efficiency of anterior teeth is only 41.3%. [0003] In clinical practice, it is often difficult to open deep overbites during the correction of clear aligners, and the ortho...
