Description

Technical Field

[0001] The invention relates to the technical field of bracket position correction, and in particular to a detachable traction hook orthodontic self-locking bracket. Background Art

[0002] Brackets are important components of fixed orthodontic technology. They are directly bonded to the surface of the crown with adhesives. The archwires pass through the brackets to apply various types of correction forces to the teeth. Brackets are made of stainless steel, bioceramics or composite resins. Their main function is to fix the archwires so that the archwires can play a better role and transmit correction forces, thereby controlling the three-dimensional movement of the teeth and achieving the purpose of orthodontic treatment.

[0003] The general method of oral orthodontics is to fix brackets on the surface of teeth and install arched archwires in the grooves of brackets to generate a customized orthodontic force on the teeth. The archwires can apply force to the teeth in the appropriate direction, move or rotate the teeth in the desired direction, and move individual teeth to the desired position. The traction hook is a structure on the orthodontic bracket. Its main function is to provide additional support and force during tooth correction, and is used to pull the teeth to move or adjust the angle of the teeth. During orthodontic treatment, the doctor will selectively set an elastomer on different teeth through the traction hook according to the specific situation of the patient, thereby generating a slow and continuous release force, which generates elastic force acting on the teeth and dental arches.

DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-Figure 8As shown, a detachable traction hook orthodontic self-ligating bracket includes a bracket body and a traction hook 4 for traction of the bracket body, the bracket body is formed with an archwire slot 2-1 for installing an archwire; the bracket body is formed with a plurality of mounting holes 2-2 for plugging in the traction hook 4, the bracket body includes a bracket body 2 and a mesh bottom 1 integrally formed with the bracket body 2, the mounting hole 2-2 is formed at the connection between the bracket body 2 and the mesh bottom 1; the traction hook 4 includes a traction section 4-3 and a plug-in section 4-4 connected to each other, a positioning surface 4-1 for calibrating the installation method of the traction hook 4 is formed at the connection between the traction section 4-3 and the plug-in section 4-4, and a bending section 4-2 for being arranged around the bracket body 2 is formed at the end of the plug-in section 4-4.

[0029] The archwire slot 2-1 is a through slot formed on the bracket body. With the action of the archwire slot 2-1, multiple required bracket bodies can be installed on the same archwire, and each bracket body is provided with a traction hook 4 according to needs. When the position of the bracket body needs to be adjusted, the traction hook 4 is plugged into the corresponding bracket body.

[0030] The traction hook 4 is composed of a traction section 4-3, an insertion section 4-4 and a bending section 4-2 which are connected in sequence. The traction section 4-3 is exposed to the air, and the insertion section 4-4 is inserted into the bracket body 2. The traction force can be transferred to the bending section 4-2 by pulling the traction section 4-3, thereby achieving traction of the bracket body 2.

[0031] The plug-in section 4-4 is arranged along the length direction of the traction section 4-3, and an angle is formed between the traction section 4-3 and the plug-in section 4-4. Under the action of the angle, when the plug-in section 4-4 is plugged into the corresponding bracket body 2, the traction section 4-3 is abutted against the surface of the bracket body 2 under the action of the angle, thereby preventing the traction section 4-3 from being inserted into the bracket body 2 and ensuring the position of the bending section 4-2.

[0032] The plug-in section 4-4 is located inside the bracket body 2, the bending section 4-2 is in contact with the outer wall of the bracket body 2, and the bending section 4-2 and the pulling section 4-3 are respectively arranged on opposite sides of the bracket body 2, so that under the action of the pulling section 4-3, the force on the other side of the bracket body 2 is adjusted through the bending section 4-2.

[0033] The positioning surface 4-1 is a planar structure, and the positioning surface 4-1 is in contact with the net bottom 1. Under the action of the positioning surface 4-1, the positions of the bending section 4-2, the traction section 4-3 and the plug-in section 4-4 are limited to prevent the bending section 4-2, the traction section 4-3 and the plug-in section 4-4 from rotating during use of the traction hook 4, thereby improving the traction effect of the traction hook 4.

[0034] The traction hook 4 is cross-arranged with the archwire slot 2 - 1 , so that the traction hook 4 will not interfere with the archwire during use, thereby ensuring the connection stability between the archwire and the bracket body 2 .

[0035] The traction section 4-3, the plug-in section 4-4 and the bending section 4-2 are an integrated structure, which facilitates the transmission of force and also makes the whole have better stability.

[0036] A sliding cover 3 for covering the archwire slot 2-1 is provided on the bracket body 2. The sliding cover 3 is slidably connected to the bracket body 2. A dovetail groove structure adapted to the bracket body 2 is formed at the bottom of the sliding cover 3. The sliding cover 3 slides along the radial direction of the archwire slot 2-1. The state of the archwire slot 2-1 is controlled under the sliding action of the sliding cover 3.

[0037] A slide groove 3-1 is formed in the middle of the sliding cover 3, and a U-shaped spring 5 abutting against the slide groove 3-1 is provided in the bracket body 2. The U-shaped spring 5 is clamped in the corresponding slide groove 3-1. During the sliding process of the sliding cover 3, the slide groove 3-1 slides synchronously with the sliding cover 3. When the sliding cover 3 slides to a certain position, the U-shaped spring 5 abuts against the side of the slide groove 3-1 to limit the sliding position of the sliding cover 3.

[0038] Arc surfaces are formed on both sides of the slide groove 3-1 along the sliding direction of the sliding cover 3. The middle part of the arc surface bulges inward, and the two ends of the arc surface form an open state locking position 3-2 and a closed state locking position 3-3 that are compatible with the U-shaped spring 5. During the sliding process of the sliding cover 3, the slide groove 3-1 slides synchronously with the sliding cover 3. When the U-shaped spring 5 passes through the arc surface, the U-shaped spring 5 undergoes elastic deformation. When the U-shaped spring 5 moves to the open state locking position 3-2 or the closed state locking position 3-3, the U-shaped spring 5 is reset under the action of its own elastic force to achieve the card connection and positioning with the slide groove 3-1.

[0039] The sliding cover 3 and the bending section 4 - 2 are located on the same side of the bracket body 2 , ensuring that the sliding of the sliding cover 3 does not interfere with the pulling section 4 - 3 .

[0040] In actual use, the traction hook 4 is in a long strip state before installation, and the bending section 4-2 is not formed at this time. After the traction hook 4 is installed in place, the tail of the plug-in section 4-4 of the traction hook 4 is bent to form the bending section 4-2, so that the bracket body 2 is surrounded and abutted by the bending section 4-2 and the plug-in section 4-4, and the plug-in section 4-4 and the bending section 4-2 are pulled by the traction section 4-3, thereby achieving traction of the bracket body 2.
