Description

Technical Field

[0001] The utility model relates to the technical field of removable orthodontic appliances, and specifically, to a removable orthodontic appliance for posterior tooth malocclusion deformity. Background Art

[0002] Individual tooth displacement is very common in tooth deformities. The tooth condition shows that only a few individual teeth are misaligned, while the other teeth are normal. Tooth displacement not only affects the aesthetics of teeth, but also easily causes food impaction, and it is not easy to clean the teeth, leading to a series of oral diseases. Tooth displacement affects oral function, and then affects the digestive system and physical health.

[0003] A forward traction combined arch expansion appliance with the patent number CN219184212U includes an arch expander, traction hooks and an elastic correction member. The arch expander is arranged inside the upper jaw and is suitable for applying an outward expansion force to the upper jaw dental arch; there are two traction hooks, one ends of the two traction hooks are respectively connected with an extraoral traction device, and the other ends are respectively adjacent to the teeth on both sides, and are suitable for forwardly traction the upper jaw bone; the elastic correction member is used for correcting the palatally displaced teeth, one end of the elastic correction member is connected with the arch expander, and the other end elastically abuts against the lingual side of the teeth to be corrected, and is suitable for applying a force towards the labial side. The appliance provided in this application integrates the arch expander, traction hooks and elastic correction member, and can realize the simultaneous correction of upper jaw dental arch expansion, upper jaw bone traction and individual lingual-palatal displaced teeth, greatly shortening the correction period and simplifying the correction process, saving a lot of time and economic costs for patients.

[0004] In this patent, according to the number of palatally displaced teeth, the same number of double-curved lingual springs are installed on the fixing frame. The double-curved lingual springs apply a force towards the labial side to the palatally displaced teeth, promoting the labial inclination and reduction of the teeth. Although the tooth correction effect can be achieved, the operation is relatively cumbersome, and it is necessary to adjust the angle of the double-curved lingual springs and their positions on the fixing frame multiple times, further causing the patient's mouth to be in an open state for a long time, further causing fatigue and affecting the comfort. Summary of the Utility Model

[0005] The utility model provides a removable orthodontic appliance for posterior tooth malocclusion deformity, which solves the problem of a removable orthodontic appliance for posterior tooth malocclusion deformity in the related art.

[0006] The technical solution of the utility model is as follows: A removable orthodontic appliance for posterior tooth malocclusion deformity includes an appliance body. A sliding groove is formed on the upper surface of the appliance body. A connecting column is slidably connected in the sliding groove. A slider is fixedly connected to the lower surface of the connecting column. An arc-shaped sliding groove is formed below the sliding groove. The slider is arranged in the arc-shaped sliding groove. A first spring is fixedly connected to the outer peripheral surface of the connecting column. One end of the first spring away from the connecting column is fixedly connected with a pushing block for pushing the teeth to move.

[0007] Further, connecting plates are fixedly connected to both side surfaces of the orthodontic appliance body. The other ends of the two connecting plates are interconnected with a clamp. Three annular sleeves are slidably connected to the clamp. First, second, and third retaining rings are fixedly connected to the outer peripheral surfaces of the three annular sleeves respectively. The opposite surfaces of the second retaining ring and the third retaining ring are fixedly connected by a second spring.

[0008] Further, support blocks are fixedly connected to the upper surfaces of the second retaining ring and the third retaining ring respectively. The two support blocks are arranged oppositely.

[0009] Further, a rectangular plate is fixedly connected to the outer periphery of the connecting column. The other end of the rectangular plate away from the connecting column is slidably connected with a rectangular frame. The other end of the rectangular frame is fixedly connected to a push block.

[0010] Further, the orthodontic appliance body is made of baseplate resin material, and the first spring and the second spring are made of 0.3 mm metal material.

[0011] The working principle and beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, by sliding the connecting column, the position of the push block is changed, and the first spring is forced to retract. According to the position of the posterior teeth with malocclusion, the connecting column is slid, so that the push block is fitted to the posterior teeth with malocclusion, and the posterior teeth with malocclusion are pushed by the resilience of the first spring. It is convenient and fast, and it does not require the patient's mouth to be open for a long time, further increasing the comfort of the patient.

[0013] 2. In the present utility model, when sliding the three annular sleeves, the first, second, and third retaining rings are moved, and the first retaining ring is fixed on the right side of the tooth. Then, according to the position of the posterior teeth with malocclusion, the second and third retaining rings are clamped onto the teeth on both sides of them. Then, the position of the posterior teeth with malocclusion is opened by the elastic force of the second spring, accelerating the entry of the posterior teeth with malocclusion and improving the treatment efficiency and reducing the wearing time of the patient.
