Embodiment 1

[0031] like Figure 1 to Figure 4 As shown, a molar appliance with convenient application of orthodontic force includes a first belt ring 1 and an anchorage, and also includes an expansion device connected in series between the first belt ring 1 and the anchorage;

[0032] The expanding device includes a screw rod 22, and the screw rod 22 is provided with two sections of external thread, and the screw threads on the two sections of external thread are opposite in direction;

[0033] Nuts 21 are threadedly connected to each external thread segment, one of the nuts 21 is fixedly connected with the first belt ring 1, and the other nut 21 is fixedly connected with the anchorage;

[0034] The first belt ring 1 is used to be fixed on the molars to be treated, and the axial direction of the screw rod 22 is parallel to the distal direction of the molars.

[0035] Specifically, the anchorage refers to the structure used to resist the reaction force generated by the orthodontic force. ...

Embodiment 2

[0040] like Figure 1 to Figure 4 As shown, this embodiment is further limited on the basis of Embodiment 1: as the specific connection form between the expansion device and the first belt ring 1 and the anchorage, the two nuts 21 are connected to the first belt ring through different connecting arms 6 respectively. 1 and connected to the anchorage. Using the above method, after multiple times of correcting forces are applied to the molars, the connecting arms 6 on one or both sides of the expanding device can be plastically deformed to a certain extent through tools, so that the direction of the correcting force can be corrected. Simultaneously, in the existing position adjustment of the molars, the molars only need to move a few millimeters in the far or mesial direction. In this way, for the comfort of the patient, the total length of the screw rod 22 does not need to be too long. A few millimeters is enough, and the connecting arm 6 is used as the intermediate connecting ...

Embodiment 3

[0047] like Figure 1 to Figure 4 As shown, this embodiment provides a more detailed solution on the basis of Embodiment 1: in order to facilitate the application of torque to the screw 22 to make it rotate around its own axis and achieve the purpose of adjusting the relative position of the two nuts 21, the The screw 22 is also provided with a driving segment 23 , and the driving segment 23 is provided with a plurality of holes, and the holes are uniformly distributed in a circular shape relative to the axis of the screw 22 . In this solution, by setting multiple holes and limiting the relative positions of the multiple holes, the screw rod 22 can be rotated to any state, and the corresponding holes are exposed to the position that is convenient for the patient to insert the force-applying member, that is, this solution greatly The convenience of adjusting the appliance is improved.

[0048] Because when the patient adjusts the expansion device, it is difficult to avoid appl...

Abstract

The invention discloses a molar orthodontic appliance capable of conveniently applying orthodontic force. The molar orthodontic appliance comprises first bands, anchorages and expanding devices connected between the first bands and the anchorages in series; each expanding device comprises a screw, wherein the screw is provided with two outer threaded segments, the screwing directions of threads formed in the two outer threaded segments are opposite, a nut is connected to each outer threaded segment in a threaded mode, one nut is fixedly connected with the corresponding first band, and the other nut is fixedly connected with the corresponding anchorage; the first bands are used for being fixed to molars to be subjected to orthodontic treatment, and the axial direction of the screw is parallel to the middle-far direction of the molars. By adopting the orthodontic appliance, a patient can independently apply the orthodontic force on corresponding teeth, orthodontic force applying operation is easy, and the subsequent visit frequency of the patient can be effectively decreased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a molar appliance for convenient application of orthodontic force. Background technique [0002] In the prior art, molar appliances are mostly used to open up interdental spaces and adjust the relationship between molars and jaws. The force applied by the square wire and the force applied by the spring are both to apply the correction force to the tooth that is expected to move through the elastic recovery force of the corresponding material: in the square wire arch orthodontic technology, the torque control of the tooth depends on the third sequence of bending made on the arch wire , the way of spring force is mostly by controlling the fixed point of the spring, such as changing the connection point of the spring on the anchorage through the ligature wire. However, the above control of the correction force through the third sequence bending is highly dependent on the do...
