Description

Technical Field

[0001] This utility model belongs to the field of medical device technology for orthodontics, specifically a clamp for indirect bonding of orthodontic buccal tubes. 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 accurately 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 of them still have some shortcomings. Water-soluble adhesive requires continuous rinsing and is easy to leave residue in the patient's mouth, and the operation is time-consuming. Ligature retainer retention requires the ligature to be removed, which is also time-consuming. Snap-fit ​​retention is prone to "false positioning" during assembly, that is, due to friction, it is thought to be in place during assembly, but it is not actually in place, resulting in bonding errors.

[0004] Chinese patent CN219782769U discloses a clamp for indirect bonding of orthodontic buccal tubes. It includes a clamp body with a clamping groove at one end. A vertical limiting plate protruding from the clamp body is located at the top of the clamping groove. Retention posts are provided on the left and right sides of the clamping groove to prevent the buccal tube from detaching from the clamp body. An anti-rotation retention plate is provided on the rear side of the clamping groove to prevent rotational displacement of the buccal tube within the groove. An auxiliary positioning detection hole is provided on the side wall of the clamping groove. This invention provides an auxiliary positioning detection hole communicating with the buccal tube groove on the side, allowing the buccal tube to be guided into place by a probe passing through the groove, preventing false positioning. Furthermore, it eliminates the need for additional fixing accessories, making clinical insertion and removal more convenient. However, when clamping the orthodontic buccal tube, stress concentrates on the two wings of the clamping groove, potentially leading to wing breakage. Summary of the Invention

[0005] In view of the shortcomings of the current market, the purpose of this utility model is to provide an elastic clamp for indirect bonding of orthodontic brackets, which has high structural strength and is not easy to break.

[0006] The purpose of this application is achieved through the following technical solution.

[0007] A clamp for indirect bonding of orthodontic buccal tubes includes a clamp body, one end of which is provided with an orthodontic buccal tube retention portion, the orthodontic buccal tube retention portion including a clamping groove, the center of which is provided with a U-shaped cut through the clamp body.

[0008] Preferably, a proximal retention post is provided on one side of the clamping groove, protruding from the side wall of the clamping groove, and a distal retention post is provided on the other side of the clamping groove, located at the front end of the clamping groove. The proximal retention post is used to extend into the proximal groove opening of the buccal tube, and together with the distal retention post, prevents the buccal tube from falling out of the clamp.

[0009] Preferably, a cheek-surface tube guiding inclined surface is provided at the front end of the clamping groove wall on the same side as the near-center fixed pile. During assembly, the cheek-surface tube guiding inclined surface facilitates the sliding of the cheek-surface tube into the clamp.

[0010] Preferably, an anti-rotation retention plate is provided at the lower end of the clamping groove wall on the same side as the distal retention pile. The anti-rotation retention plate is used to insert into the gap between the cheek tube body and the base plate, guide the cheek tube to the correct torque position, and prevent rotational displacement in the clamp.

[0011] Preferably, an auxiliary positioning detection hole is provided on the wall of the clamping groove on the side opposite to the near-center fixed pile. After assembly, the auxiliary positioning detection hole is aligned with the cheek tube groove, and a probe can be passed through the cheek tube groove to guide the cheek tube that is not fully positioned into complete position.

[0012] Preferably, the U-shaped groove is provided with vertical limiting plates on both sides. The vertical limiting plates can prevent the cheek tube from coming off vertically due to excessive force during the bonding and pressing process.

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

[0014] Preferably, the top surface and side surface of the U-shaped groove are transitioned by an arc surface.

[0015] Preferably, the top surface of the clamping groove and the rear side surface of the clamping groove are transitioned by an arc surface.

[0016] Preferably, the front side of the U-shaped groove is provided with an orthodontic buccal tube mounting port, and the lateral width of the orthodontic buccal tube mounting port is greater than the lateral width of the U-shaped groove.

[0017] Compared with the prior art, this application has at least the following obvious advantages and effects:

[0018] This invention reduces the lateral strength of the clamping section guide plate by setting a U-shaped groove in the clamping groove, so that the clamping part can be laterally expanded and deformed with a smaller force, which is beneficial for the positioning and dislocation of the cheek tube. Furthermore, the stress generated during positioning and dislocation is concentrated in the U-shaped groove area, where the clamping thickness is the largest, the strength is high, and it is not easy to break.

[0029] In the embodiments of this application, a cheek tube 12 guiding inclined surface 7 is provided at the front end of the clamping groove 3 wall on the same side as the near-center retention pile 5. The cheek tube 12 guiding inclined surface 7 facilitates the cheek tube 12's sliding into the clamping groove 3 during assembly. An anti-rotation retention plate 8 is provided at the lower end of the clamping groove 3 wall on the same side as the far-center retention pile 6. The anti-rotation retention plate 8 is used to insert into the gap between the cheek tube 12 body and the base plate, guiding the cheek tube 12 to the correct torque position and preventing rotational displacement within the clamping groove 3. An auxiliary positioning detection hole 9 is provided on the clamping groove 3 wall on the opposite side of the near-center retention pile 5. After assembly, the auxiliary positioning detection hole 9 faces the cheek tube 12 groove, allowing a probe to pass through the cheek tube 12 groove and guide any partially positioned cheek tube 12 into complete positioning.

[0030] In addition, vertical limiting plates 10 are provided on both sides of the U-shaped groove 4. The vertical limiting plates 10 can prevent the cheek tube 12 from coming off vertically due to excessive force during the bonding and pressing process. The top surface and side surface of the U-shaped groove 4 are transitioned by an arc surface. The top surface of the clamping groove 3 is transitioned by an arc surface to the rear side surface of the clamping groove 3.

[0031] The holder body 1 is made of photosensitive resin by 3D printing. The front side of the U-shaped groove 4 is provided with an orthodontic buccal tube 12 mounting port 11, and the lateral width of the orthodontic buccal tube 12 mounting port 11 is greater than the lateral width of the U-shaped groove 4.
