Description

Technical Field

[0001] The invention relates to the field of tooth orthodontics, in particular to an orthodontic device for twisting teeth. Background Art

[0002] Malocclusion is one of the most common oral diseases. Although there are many types and manifestations of malocclusion, the vast majority of patients have single or multiple tooth twisting. Ideally, the upper and lower teeth should be arranged in a smooth, symmetrical arch; if the teeth are twisted, in addition to affecting the appearance, it will also lead to poor contact between the teeth and affect the chewing function; at the same time, overly twisted teeth are not easy to clean, which may lead to caries, gingivitis, periodontitis, etc. Therefore, during orthodontic treatment, the correction of tooth twisting is beneficial to improve the treatment effect and promote the health of patients. However, whether it is the use of highly elastic archwires to align the teeth in the early stage of treatment, or the fine adjustment by various means at the end of treatment, the correction of twisted teeth is difficult. On the one hand, the correction of twisted teeth directly depends on the accuracy of the bracket bonding position, but this is related to many factors such as the experience of the clinician, the field of view of oral operation, and the bonding space on the tooth surface. It is difficult to bond to the most accurate position at one time. On the other hand, due to the existence of the bracket clearance angle, the archwire may have a certain amount of displacement in the groove, which makes the mechanical load generated by the archwire insufficient. Even if the bracket bonding position is accurate, it may not be fully corrected in the end. At the same time, since correcting the anterior tooth twisting requires the consumption of the dentition space, correcting the posterior tooth twisting will provide the dentition space, so the correction of twisted teeth needs to be considered in combination with the available space of the dental arch, which undoubtedly increases the difficulty of treatment.

[0003] At present, the commonly used methods for correcting tooth torsion in clinical practice are to adjust the position of the bracket and re-bond it or to use the existing finished rotating pad, but both methods have obvious disadvantages. The former overcomes the problem of inaccurate bonding in the early stage of correction by removing the original bracket, readjusting the position and then performing secondary bonding. It can also offset the adverse effects of the clearance angle by over-correction positioning in the torsion direction, thereby promoting the rotation of the twisted tooth to the ideal position. However, since the bracket needs to be removed from the tooth surface and re-bonded, this process will cause pain and discomfort to the patient; since the bracket base is not brand new, it is easy to cause a decrease in bonding after secondary bonding, which is easy to cause repeated falling off in the later stage; after re-bonding, it is often necessary to use a thinner archwire for realignment, which also increases the treatment cycle and reduces the correction efficiency. The finished rotating pad can be placed directly at the far torsion of the bracket, and by raising the correction archwire and changing the archwire curvature, the teeth are forced by the characteristic of the archwire rebounding to its original state. This force-adding process is passive, and its mechanical loading depends on the size of the archwire rebound force. However, due to the simple structure of the rotating pad, the mechanical properties cannot be adjusted; it can only be placed on the bracket body, and the change of the archwire curvature is small, and the archwire rebound force that can be used is often insufficient; and because the force point of the rotating pad is close to the rotation center of the tooth, the force arm is short, the torque to correct the torsion is small, and it is difficult to drive the tooth to rotate, and the correction efficiency is very low. In summary, a simple and efficient method is urgently needed in clinical practice to correct tooth torsion problems. Summary of the invention
