Description

Technical Field

[0001] This utility model belongs to the field of medical device technology for orthodontics, specifically a magnetic indirect bonding clamp for orthodontic brackets. Background Technology

[0002] In the field of orthodontics, the crucial orthodontic appliance components, brackets, can only be manually bonded to the teeth one by one by the dentist, relying on visual inspection. This is not only time-consuming and labor-intensive, but also makes it difficult to achieve the required height, angle, and tilt, resulting in unsatisfactory treatment outcomes. Therefore, a technique using digitally fixed orthodontic brackets for indirect bonding has emerged.

[0003] Digital fixed orthodontic indirect bonding technology can precisely position the buccal tube on the tooth surface, but the operation is not ideal when transferring the designed position into the patient's mouth. Currently, the main clamps on the market use water-soluble adhesive retention, ligature retainer retention, and snap-fit ​​structure, but all still have some shortcomings. Water-soluble adhesive requires continuous rinsing and is prone to residue in the patient's mouth, and the operation is time-consuming. Ligature retainer retention requires removing the ligature to remove it, which is also time-consuming. Snap-fit ​​retention is prone to "false positioning" during assembly.

[0004] Chinese utility model patent CN216754657U discloses an indirect bonding locator for orthodontic brackets, comprising an elastic clamping rod and an occlusal positioning plate. One end of the elastic clamping rod is vertically inserted into the end of the occlusal positioning plate, and the other end of the elastic clamping rod is provided with an orthodontic bracket retention part. The orthodontic bracket retention part includes a retention groove, and bracket retention posts protruding from the inner wall of the retention groove are provided on both sides of the inner wall of the retention groove. The top of the retention groove is provided with a guide plate elastic groove that communicates with the retention groove. The retention groove in the above-mentioned indirect bonding locator has a semi-open structure, so when transferring orthodontic brackets, the orthodontic brackets are prone to slipping off the end of the retention groove, and the limiting is not stable enough. Utility Model Content

[0005] In view of the shortcomings of the current market, the purpose of this utility model is to provide a magnetic indirect bonding clamp for orthodontic brackets, which has the characteristics of stable fixation, not easy to slip off, and convenient disassembly after bonding.

[0006] The objective of this application is achieved through the following technical solution:

[0007] A magnetic indirect bonding clamp for orthodontic brackets includes a clamp body. One end of the clamp body is provided with an orthodontic bracket retention part. The orthodontic bracket retention part includes two clamping arms. A clamping groove is provided between the two clamping arms. A strong magnet placement groove communicating with the clamping groove is provided above the clamping groove. A strong magnet support platform is provided at the rear side of the clamping groove. A strong magnet is installed in the strong magnet placement groove, and the rear side below the installed strong magnet is supported by the strong magnet support platform.

[0008] Preferably, the rear side of the strong magnet placement slot is provided with a U-shaped groove, which penetrates through the clamp body and is connected to the strong magnet placement slot at the front. The U-shaped groove can reduce the lateral strength of the clamp body, making it exhibit stronger lateral toughness, which is convenient for lateral clamping of the orthodontic bracket.

[0009] Preferably, the two clamping arms on the front side of the clamping slot are provided with a bracket gingival anti-dislodgement limiting band. The bracket gingival anti-dislodgement limiting band protrudes towards the middle position. The bracket gingival anti-dislodgement limiting band mainly supports the orthodontic bracket in the gingival and labial / lingual positions to prevent the orthodontic bracket from sliding out from the gingival direction.

[0010] Preferably, the clamping groove is provided with two bracket engagement anti-dislodgement limiting bands on its rear side, which are located below the strong magnet support platform. These bands restrict the position of the bracket lip to prevent the bracket from sliding out from the tongue side.

[0011] Preferably, the slot for placing the strong magnet is circular.

[0012] Preferably, the bottom of the clamp body and both sides of the U-shaped groove are provided with a recessed anti-adhesion structure. The anti-adhesion structure provides space for excess adhesive that may overflow during the bonding process, preventing the adhesive from sticking the guide plates together.

[0013] Preferably, the holder body is made of photosensitive resin by 3D printing.

[0014] Preferably, the transverse width of the strong magnet placement groove is greater than the transverse width of the U-shaped groove.

[0015] Compared with the prior art, this application has at least the following obvious advantages and effects:

[0016] 1. By installing a strong magnet on the holder body, the top of the orthodontic bracket can be attracted by the strong magnet when transferring the bracket, while the side is clamped by the clamping arm, making the transfer process more stable.

[0017] 2. In this utility model, the positioning and dislocation process of the orthodontic bracket is mainly controlled and positioned by a strong magnet, which will not affect the holder body. Attached Figure Description
