| description | The normal torque angle of the maxillary anterior teeth is an important factor in the aesthetics and func⁃
tion of the anterior teeth, and torque control of the front teeth is an extremely important aspect of the correction process.
At present, the normal torque angle of the front teeth is among the phase Ⅲ clinical test items recognized by the Ameri⁃
can orthodontic professional committee; consequently, good control of front teeth torque is of great significance to the
aesthetics of the upper anterior teeth. In this paper, the influence of a lip appliance on the bad torque of upper anterior
teeth and the associated methods of control are reviewed in detail. The advantages and disadvantages of various control
methods for the anterior teeth and the significance of correct anterior teeth torque angle are summarized. The existing re⁃
search results indicate that the torsion of a straight arch wire applied directly to individual teeth is too great, making it
difficult to enter the groove. Although the bending of the arch wire overcomes these shortcomings, the procedure is cum⁃
bersome; it stimulates the soft tissue of the vestibular groove and increases the patients discomfort. The bending mecha⁃
nism of the rocking chair is more complicated; it is greatly affected by the friction between the arch wire and the brack⁃
et and is not conducive to closing the tooth extraction gap using the sliding method. The portal auxiliary arch and the
single bending torque are suitable for correcting the torque angle of a single tooth. Auxiliary arch torque can be used to
correct the upright upper anterior teeth during the process of closing the extraction space and after adduction; therefore,
this procedure is worth popularizing. However, the accuracy of orthodontic control of anterior teeth torque requires fur⁃
ther study. |
