AI Technical Summary
In existing technologies, in orthodontic tooth extraction cases, the anterior tooth torque is out of control when the anterior teeth are retracted, resulting in excessive lingual inclination of the crown and relative labial inclination of the root. Existing solutions are expensive, time-consuming, or have poor results.
A lip muscle high hook-controlled torque bracket is designed, which includes a bracket, a traction arm, a lip muscle pressure block, a limit block and a rubber band. The lip inclination of the anterior teeth is controlled by lip muscle pressure and a high traction rubber band to avoid additional archwire bending.
It achieves low-cost and simple control of the lip inclination of the anterior teeth, reduces the risk of oral injury, has good effects and does not require additional archwire accessories, and can adapt to different alveolar bone directions.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oral orthodontics, in particular to a lip muscle high-position hook-controlled torque bracket. Background Art
[0002] In orthodontic tooth extraction cases, the problem of uncontrolled anterior tooth torque during retraction is often encountered. This problem causes the crown to tilt too lingually and the root to tilt relative to the labial side, resulting in a root window from the labial bone. The existing solutions to this problem are: 1. Use high-torque brackets, but such brackets are expensive and time-consuming to show clinical results; 2. Additional stainless steel square wires are bent to express positive anterior tooth torque, causing the crown to tilt labially and the root to tilt lingually, but this requires high technical requirements and requires long chairside time; 3. Use long traction hooks on the archwire to bring the force close to the tooth's resistance center to avoid tilting and movement, but this method is not effective and the height is far from reaching the tooth's resistance center. Utility Model Content
[0003] In order to solve the above problems in the prior art, the present invention provides a lip muscle high hook-controlled torque bracket, which is achieved through the following technical solutions:
[0004] A lip muscle high hook-controlled torque bracket comprises a bracket, a traction arm is connected to the top of the bracket, a lip muscle pressure block is connected to the top of the traction arm, and the lip muscle pressure block is provided with a certain thickness along the labiolingual direction.
[0005] The utility model is further configured as follows: the lip muscle pressing block is a square block, and all sides of the lip muscle pressing block are rounded.
[0006] The utility model is further configured as follows: the bracket includes a base, bracket wings and a groove, and the bracket wings are fixed to the surface of the base to form the groove.
[0007] The utility model is further configured as follows: a limiting block is protruding from one side of the traction arm surface close to the lip muscle pressure block, a groove hook is formed between the limiting block and the lip muscle pressure block, and a rubber band is sleeved in the groove hook.
[0008] The utility model is further configured as follows: the traction arm is a metal arm, and the traction arm can be bent into different angles.
[0009] The utility model is further configured as follows: the traction arm is fixedly connected to the base, the protruding direction of the limit block is the same as the direction of the bracket wing, and the rear side of the lip muscle pressure block and the rear side of the traction arm are located in the same plane.
[0010] In summary, the beneficial technical effects of the present invention are:
[0011] The utility model is simple to manufacture, has low cost for patients, and does not require high technical skills for doctors. After removing the original device, the device can be re-bonded without additional arch wire bending or the use of other arch wire accessories. Moreover, it is under the pressure of the lip muscles and has good use effect, which fills the technical gap of not relying on the power of the lip muscles for improvement; the rounded corners of all sides of the lip muscle pressure block can avoid damage to the patient's oral cavity; the limit block can prevent the rubber band from sliding on the traction arm, and perform high-position traction to adjust the lip inclination (torque) of the anterior teeth; the traction arm can be bent to adapt to different alveolar bone directions and lip muscle positions.

[0016] The present invention will be described in further detail below with reference to the accompanying drawings.
[0017] Example
[0018] like Figure 1-3 As shown, a lip muscle high-position hook-controlled torque bracket disclosed in the utility model includes a bracket 1, a traction arm 2 is connected to the top of the bracket 1, a lip muscle pressure block 3 is connected to the top of the traction arm 2, and the lip muscle pressure block 3 is set to a certain thickness along the labiolingual direction.
[0019] The lip muscle pressing block 3 is a square block, and all sides of the lip muscle pressing block 3 are rounded.
[0020] The bracket 1 includes a base 4 , bracket wings 5 and a groove 6 , and the bracket wings 5 are fixed to the surface of the base 4 to form the groove 6 .
[0021] A limiting block 7 is protruded from one side of the surface of the traction arm 2 close to the lip muscle pressure block 3 , and a slot hook 8 is formed between the limiting block 7 and the lip muscle pressure block 3 , and a rubber band 9 is sleeved inside the slot hook 8 .
[0022] The traction arm 2 is a metal arm, and the traction arm 2 can be bent into different angles.
[0023] The traction arm 2 is fixedly connected to the base 4 , the protruding direction of the limit block 7 is the same as the direction of the bracket wing 5 , and the rear side of the lip muscle pressing block 3 and the rear side of the traction arm 2 are located in the same plane.
[0024] The specific implementation method of this example is as follows: the bracket 1 is bonded to the tooth surface, the lip muscle pressure block 3 is located between the upper lip and the upper gum or between the lower lip and the lower gum, the lip muscle pressure block 3 squeezes the lips outward, and the lips apply pressure to the lip muscle pressure block 3 in the reverse direction; the front teeth are retracted and moved inward by the traction of the rubber band, because the force point is close to the root, there is an additional torque in the direction of crown lip inclination of the upper and lower front teeth; there is no need for additional arch wire bending or the use of other arch wire accessories, and the lip inclination of the front teeth is controlled by the strength of the lip muscles and the strength of the high-position traction rubber band.
