Description

Technical Field

[0001] This utility model relates to the field of orthodontic instrument technology, specifically to an orthodontic tooth advancement spring device. Background Technology

[0002] Orthodontics mainly studies the etiology and mechanism of malocclusion and deformities, as well as their diagnosis, analysis, prevention, and treatment. Orthodontics can achieve the effect of aesthetic teeth. Orthodontic treatment mainly uses various orthodontic appliances to adjust the coordination between facial bones, teeth, and nerves and muscles of the maxillofacial region. Spring pushers are required during orthodontic treatment.

[0003] However, after installation, the thrust of traditional orthodontic push spring devices cannot be flexibly adjusted. During orthodontic treatment, the distance between the two ends of the push spring will increase after the teeth are slightly displaced, which will reduce the thrust of the push spring and cause the subsequent orthodontic effect to be worse. Utility Model Content

[0004] The purpose of this invention is to provide an orthodontic tooth advancement spring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an orthodontic tooth advancement spring device, including a bracket seat, and further comprising,

[0006] The fixing base has a threaded hole on its surface;

[0007] A connecting plate and an adjusting plate are provided. A threaded seat 1 is fixedly connected to the surface of the connecting plate. A threaded seat 2 is fixedly connected to one side of the adjusting plate. A screw 1 is threaded through the threaded seat 2. The tail end of the screw 1 is threaded to the side of the threaded seat 1. A push spring is fixedly connected between the two adjusting plates.

[0008] Preferably, the fixing seat has a through hole in the middle and an orthodontic wire is slidably connected through the inner wall of the through hole, and the orthodontic wire passes through the interior of the push spring.

[0009] Preferably, the surface of the connecting plate is threaded with a second screw, the tail end of the second screw is threaded into the inner wall of the threaded hole of the fixing seat, and one side of the connecting plate is attached to the surface of the fixing seat.

[0010] Preferably, an arc-shaped patch is fixedly connected to the surface of the adjustment plate, and a soft baffle is attached to one side of the arc-shaped patch by an adhesive, the soft baffle surrounding one side of the push spring.

[0011] Preferably, a socket is provided on one side of the fixing base, and the two ends of the orthodontic wire are bent and inserted into the inner wall of the socket.

[0012] Preferably, a protruding plate is fixedly connected to the side of the fixing seat away from the connecting plate. The protruding plate is cross-shaped, and the fixing seat and the protruding plate are bonded to the surface of the bracket seat by adhesive.

[0014] Preferably, the soft baffle is made of a transparent material.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, by setting up a connecting plate and an adjusting plate, allows for the adjustment of the push spring's force by rotating screw one with a small screwdriver after slight tooth displacement. This causes the threaded seats one and two to move further apart, thereby shortening the distance between the two ends of the push spring and increasing its compression state. This maintains the proper thrust and allows for flexible adjustment. This solves the problem that in traditional orthodontic push spring devices, the push spring's force cannot be flexibly adjusted after installation, and the distance between the two ends of the push spring increases after slight tooth displacement during orthodontic treatment, leading to a decrease in the push spring's force and a deterioration in subsequent orthodontic results.

[0017] This utility model, by setting two screws and a connecting plate, allows for the timely replacement of a stronger push spring when the push spring cannot meet the current orthodontic needs, by first removing the orthodontic wire and then removing the connecting plate, thus meeting the orthodontic requirements at different stages.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 This utility model provides a technical solution: an orthodontic tooth advancement spring device, including a bracket 1, and further comprising,

[0024] Fixing base 2, the surface of fixing base 2 is provided with threaded holes;

[0025] Connecting plate 3 and adjusting plate 4, threaded seat 1 5 is fixedly connected to the surface of connecting plate 3, threaded seat 2 6 is fixedly connected to one side of adjusting plate 4, screw 1 7 is threaded through threaded seat 2 6, and the tail end of screw 1 7 is threadedly connected to the side of threaded seat 1 5. Push spring 8 is fixedly connected between the two adjusting plates 4.

[0026] The fixing base 2 has a through hole in the middle and an orthodontic wire 10 is slidably connected through the inner wall of the through hole. The orthodontic wire 10 passes through the inside of the push spring 8 to provide basic support for orthodontic treatment.

[0027] The surface of the connecting plate 3 is threaded with screw 2 9. The tail end of screw 2 9 is threaded into the inner wall of the threaded hole of the fixing seat 2. One side of the connecting plate 3 is attached to the surface of the fixing seat 2. The connecting plate 3 is installed on the surface of the fixing seat 2 by screw 2 9, which is convenient for disassembly and assembly. The push spring 8 can be replaced. Different push springs 8 with different thrusts can be replaced at different stages of correction to improve the orthodontic effect.

[0028] An arc-shaped patch 12 is fixedly connected to the surface of the adjustment plate 4. A soft baffle 13 is attached to one side of the arc-shaped patch 12 with an adhesive. The soft baffle 13 surrounds one side of the push spring 8 and provides a certain degree of shielding for the push spring 8, reducing the probability of food residue remaining on the push spring 8 during meals and improving hygiene.

[0029] The fixing base 2 has a socket 11 on one side. The two ends of the orthodontic wire 10 are bent and inserted into the inner wall of the socket 11. The socket 11 fixes the two ends of the orthodontic wire 10 to prevent the orthodontic wire 10 from sliding arbitrarily and to prevent the two ends of the orthodontic wire 10 from rubbing against the gums and causing discomfort.

[0030] A protruding plate 14 is fixedly connected to the side of the fixing seat 2 away from the connecting plate 3. The protruding plate 14 is cross-shaped. The fixing seat 2 and the protruding plate 14 are bonded to the surface of the bracket seat 1 with adhesive. The shape and size of the slot of the protruding plate 14 correspond to the slot of the bracket seat 1. The fixing effect is improved after bonding with adhesive.

[0031] The side of the bracket 1 away from the fixation seat 2 is bonded to the tooth with dental adhesive. The bracket 1 is connected to the tooth and defines the position of the fixation seat 2.

[0032] The soft baffle 13 is made of transparent material, which makes it easy to observe the condition of the push spring 8 when cleaning the mouth. It can be removed by the user to clean the push spring 8.

[0033] Working principle: The bracket 1 is fixed to the tooth surface with dental adhesive. Then, the fixation seat 2 is glued to the bracket 1 for positioning. Then, the connecting plate 3 is installed on the surface of the fixation seat 2 by screw 2 9. The orthodontic wire 10 is passed through the through hole of the fixation seat 2 and the inside of the push spring 8 to connect the two fixation seats 2. Then, the two ends of the orthodontic wire 10 are bent and the head end is inserted into the insertion hole 11. At this time, the push spring 8 is in a compressed state, applying a push force to the two teeth for orthodontic correction. When the teeth are slightly displaced, screw 1 7 is turned with a small screwdriver to move the threaded seat 1 5 and the threaded seat 2 6 away, thereby shortening the distance between the two ends of the push spring 8, increasing the compression state of the push spring 8, and maintaining the proper push force. It can be flexibly adjusted, which solves the problem that the push force of the traditional orthodontic push spring device cannot be flexibly adjusted after installation. During the orthodontic process, the distance between the two ends of the push spring will increase after the teeth are slightly displaced, which will lead to a decrease in the push force of the push spring and a worsening of the subsequent orthodontic effect.

[0034] When the push spring 8 cannot meet the push force required for the current orthodontic treatment, the orthodontic wire 10 can be removed first, and then the connecting plate 3 can be removed to replace the push spring 8 with a stronger push force in time to meet the orthodontic needs at different stages.
