Problems solved by technology

Firstly, due to the great difference in the size and shape of each patient’s dental arch, a unified tray specification cannot be well adapted to different patients, and insufficient or poor contact will affect its effect; secondly, the tooth movement targets in different areas are often Differently, in common tooth extraction cases, the front teeth need to be aligned and adducted as soon as possible, while the back teeth as anchorage generally need to move slowly or even try to move as little as possible. At this time, applying the same vibration to the front and back teeth may It will cause the anchored posterior teeth to move too fast, leading to the undesirable "anchor loss" and affect the final orthodontic effect; finally, the most suitable vibration amplitude and frequency for different tooth movement methods may be different and cannot be adjusted The vibration mode is often not suitable for all malocclusion types

Embodiment approach 1

[0061] The first embodiment of the present invention provides an orthodontic aid, see figure 1 and figure 2 As shown, it includes: a housing 1 and a vibrating device 2 arranged in the housing 1, and the vibrating device 2 is used to generate vibration;

[0062] see figure 2 As shown, the vibrating device 2 is realized by any device capable of reciprocating motion in the prior art. Typically, it may include a motor 2a and an eccentric wheel 2b connected in series to the motor 2a; the motor 2a drives the eccentric wheel 2b to rotate and generate periodic vibrations. Wherein, the motor 2a can be various motors in the prior art, in particular, it can be a linear motor.

[0063] see image 3 As shown, the orthodontic auxiliary device also includes a connecting piece 4 that is partly located inside the housing 1 and the rest is located outside the housing 1, and one end of the connecting piece 4 located outside the housing 1 is provided with a connecting portion 4a;

[0064] ...

Embodiment approach 2

[0089] The second embodiment of the present invention provides an orthodontic aid. The second embodiment is different from the first embodiment. The main difference is that in the first embodiment of the present invention, the extension part 3a2 and the connection The parts 4a are fixed to each other by bolts 5b; and in the second embodiment of the present invention, the extension part 3a2 and the connecting part 4a are engaged and fixed to each other.

[0090] Specifically, see Figure 6 As shown, in this embodiment, a protrusion 5c is formed on the extension part 3a2, and a track groove 5d is formed on the connecting part 4a;

[0091] see Figure 7 As shown, the protrusion 5c fits into the track groove 5d and fixes the extension part 3a2 and the connecting part 4a to each other.

[0092]In this embodiment, the tray 3 a can be well fixed on the connecting member 4 by virtue of the protrusion 5 c engaging with the track groove 5 d. As a further preference of this embodiment...

Embodiment approach 3

[0096] The third embodiment of the present invention provides an orthodontic aid, the third embodiment is a further improvement of the second embodiment, the main improvement is that, in the third embodiment of the present invention, see Figure 8 As shown, stop switches 5f for locking the protrusions 5c of the extensions 3a2 of each tray 3a in the track grooves 5d are provided on the connecting portion 4a near both ends of the track grooves 5d.

[0097] Such as Figure 8 As shown, when the limit switch 5f is turned on, the protrusion 5c can be embedded in the track groove 5d very conveniently, and after each tray 3a is installed, see Figure 9 As shown, the stop switch 5f is locked back, and the fixing of the tray 3a is completed.

[0098] Stop switches 5f are provided at both ends of the track groove 5d to prevent the protrusion 5c from sliding in the track groove 5d during the vibration process, and prevent the protrusion 5c from falling off from the track groove 5d, so th...

Abstract

The invention relates to the technical field of oral medical care and discloses an orthodontic assist device, comprising a housing and a vibrating device arranged in the same; the vibrating device isused for generating vibrations .The orthodontic assist device also includes a brace component releasably connected to the housing; the brace component includes a plurality of trays; each tray is responsible for part of a dental region. The orthodontic assist device is suitable for quickening the movement of a target tooth during orthodontic treatment in a specified manner.

Description

technical field [0001] The invention relates to the technical field of oral medicine, in particular to an orthodontic auxiliary device. Background technique [0002] In the process of human growth and development, due to congenital or acquired reasons, various types of malocclusion (occlusion) deformities may occur. [0003] Orthodontic treatment mainly uses various orthodontic devices to adjust the balance and coordination between facial bones, teeth, and maxillofacial nerves and muscles, and finally achieve the balance, stability and beauty of the oral and jaw system. The correction of malocclusion (occlusion) mainly relies on wearing appliances inside or outside the oral cavity to apply appropriate "biological force" to teeth, alveolar bone and jaw bone to make them move physiologically, thereby correcting malocclusion (occlusion) )deformity. The principle of orthodontic tooth movement is: under the action of the orthodontic force, the periodontal ligament is compressed...
