Background
It is common that the roots of individual teeth are located on the lingual side of alveolar bone due to crowding or the like, and in many cases, maxillary lateral incisors are dislocated palatoscopically, and in this case, the roots of teeth remain on the palatal side after the dentition is aligned and leveled. If torque control is not performed, the snap contact is affected, and the appearance is impaired. In addition, it is also seen that the labial inclination is too large during mandibular anterior hypotony, and the lower incisor root is close to the lingual laminae, which leads to absorption by the lower anterior root or penetration of the lower anterior root from the lingual side if torque control is not performed. The clinical methods for controlling the labial movement of individual tooth roots are usually as follows: the first is bending individual tooth torque on harder stainless steel square wires, the second is using pre-set high torque brackets or bracket reverse adhesion, and the third is using a traditional portal auxiliary arch. The first and the second schemes have narrow width of the bracket groove, small force arm, difficulty in providing enough torque, low torque control efficiency and long required time, and the third traditional portal auxiliary arch is the gingival of the subject dental crown
The limitation to the height, narrow case application range, insufficient torque, short force arm of a torque system and limited correction effect of the labial torque of the tooth root.
