Description

Technical Field

[0001] The present invention relates to the field of dental treatment, and particularly to a personalized arc-shaped groove self-locking bracket. Background Art

[0002] At present, with the popularization and promotion of orthodontics, orthodontic treatment is increasingly accepted by the public. During this process, the bracket is one of the important core components, and the commonly used brackets are self-locking brackets and ligature brackets.

[0003] For the existing brackets, whether they are self-locking brackets or ligature brackets, and whether they are on the lingual side or the labial side, the shape of the groove is basically rectangular. However, the arch wire used for orthodontics often has a certain curvature in many cases, and it cannot be fully matched when matching with the rectangular groove. Especially when correcting the asymmetry of the anterior tooth midline on the lingual side, it is more likely to cause the situation of inconsistent anterior tooth torque, affecting the correction effect. Summary of the Invention

[0004] In order to make the arch wire and the groove of the bracket more matched and improve the correction effect, the present application provides a personalized arc-shaped groove self-locking bracket.

[0005] The personalized arc-shaped groove self-locking bracket provided by the present application adopts the following technical solutions:

[0006] A personalized arc-shaped groove self-locking bracket includes a bracket body. One side of the bracket body is used for bonding to the tooth surface, and the other side is provided with a groove, and the groove is in an arc shape adapted to the arch wire; the bracket body is equipped with a limiting component for restricting the arch wire in the groove.

[0007] By adopting the above technical solution, when the bracket body is bonded to the lingual side of the patient's anterior teeth, referring to Figure 1 and Figure 2 , the arch wire 101 is arc-shaped in the anterior tooth segment. Therefore, the arc-shaped arch wire 101 can better cooperate with the arc-shaped groove 11, reducing some non-matching spaces when the arc-shaped arch wire 101 and the arc-shaped groove 11 cooperate, which may cause the situation that the arch wire cannot fully act on the groove and achieve a complete orthodontic force.

[0008] In addition, when the groove is a rectangular groove and the arch wire 101 is bent so that the arch wire 101 can match the rectangular groove 102 (referring to Figure 3 ), when replacing the arch wire clinically, it is easy for the bent part of the arch wire to get stuck or press against the groove, and it is difficult to smoothly insert the arch wire into the groove; while when the groove is designed to be arc-shaped, the arc-shaped arch wire can more easily enter the groove along the arc-shaped groove, and since there is no bending of the arch wire, there will be no problem of getting stuck or pressing against the groove.

[0009] Preferably, when the bracket body is bonded to the lingual side of the front teeth, the groove is inclined toward the outside of the oral cavity in the depth direction.

[0010] By adopting the above technical solution, it can be made more convenient to insert the arch wire when it is installed on the lingual side of the front teeth.

[0011] Preferably, the limit assembly includes: a locking cover, a sliding groove is provided on one side of the bracket body where the groove is provided, one end of the sliding groove is connected to the groove, and the other end is connected to the bracket body, the locking cover is slidably installed on the bracket body through the sliding groove, and one end of the locking cover is located at the notch of the groove; the limit assembly also includes: a limiting member for limiting the sliding position of the locking cover.

[0012] By adopting the above technical solution, after the arch wire is placed in the groove, the locking cover is slid so that the locking cover blocks the notch of the groove, thereby stabilizing the arch wire in the groove; and the locking cover is limited by the limiting member; the operation process is simple.

[0013] Preferably, when the bracket body is bonded to the lingual side of the front teeth, one end of the sliding groove connected to the outside of the bracket body faces outside the oral cavity.

[0014] By adopting the above technical solution, it is more convenient to install the lock cover when it is installed on the lingual side of the front teeth.

[0015] Preferably, limiting grooves are provided on both sides of the bottom of the sliding groove, and limiting strips are provided on both sides of the lock cover, and the limiting strips are slidably installed in the limiting grooves; the limiting member includes: an arc-shaped elastic axis wire, an axis wire groove is provided at the bottom of the sliding groove, the elastic axis wire is inserted into the bracket body through the axis wire groove, and the outer arc surface of the elastic axis wire is pressed against the lock cover.

[0016] By adopting the above technical solution, when the lock cover slides in the sliding groove, the lock cover squeezes the arc-shaped elastic axis wire, so that the elastic axis wire applies elastic force to the lock cover, so that the limit strip is pressed against the groove wall of the limit groove to achieve the limiting effect. This structure is convenient for limiting operation.

[0017] Preferably, the locking groove and the unlocking groove are arranged at intervals along the sliding direction of the locking cover on one side of the locking cover facing the elastic axis wire, and the locking groove and the unlocking groove are both arranged in arc surfaces on both sides of the sliding direction of the locking cover.

[0018] By adopting the above technical solution, when in the locked state, the elastic axis wire is inserted into the locking groove to achieve stable limiting of the lock cover; when it needs to be in the unlocked state, the lock cover is moved so that the elastic axis wire crosses into the unlocking groove, so that the lock cover is stably in the unlocked state, reducing the possibility of the lock cover slipping out of the stable groove, and improving the operational convenience of opening and closing the lock.

[0019] Preferably, a buckle groove is provided at a side of the notch of the groove away from the sliding groove, and the buckle groove is located at a position corresponding to the locking cover.

[0020] By adopting the above technical solution, when unlocking is needed, the doctor can directly move the lock cover through the buckle groove to reach the force point for unlocking, thereby improving the convenience of unlocking.

[0021] Preferably, a lower wing is provided at one end of the bracket body away from the sliding groove.

[0022] By adopting the above technical solution, it is convenient for doctors to tie the archwire to increase the friction between the archwire and the archwire slot, thereby improving the correction effect.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The arc-shaped archwire can better match the arc-shaped groove, reducing the situation where the archwire cannot fully act on the groove and achieve the complete correction force due to some unmatched spaces when the arc-shaped archwire and the arc-shaped groove match;

[0025] 2. When the groove is designed to be arc-shaped, the arc-shaped arch wire can be easily inserted into the groove along the arc-shaped groove, and since there is no arch wire and no bend, there will be no problem of getting stuck or pressing against the groove;

[0026] 3. When installed on the lingual side of the anterior teeth, it makes it easier to insert the archwire;

[0027] 4. After the arch wire is placed in the groove, slide the lock cover so that the lock cover blocks the notch of the groove to stabilize the arch wire in the groove; and then limit the lock cover by the limit piece; the operation process is simple. BRIEF DESCRIPTION OF THE DRAWINGS
