A supercomplect retained tooth, situated under the 21st tooth, was removed in order to eliminate the supraposition (vestibular position) of the 21st tooth under conditions of lack of place in the dental arch. The 14th tooth on the contralateral side of the jaw was removed in order to maintain the symmetry and order of the anterior part of the maxillary dental arch and for creating place for the 21st tooth. Further transposition of the 13th tooth to the place previously occupied by 14th tooth, 11th tooth instead of 12th tooth, and establishment of the 21st tooth into correct position in the dental arch were carried out using orthodontic devices.
为消除牙弓空间不足情况下21号牙的重叠（前庭位），拔除了位于21号牙下方的一颗超复杂滞留牙。为维持上颌牙弓前部的对称性和秩序，并为21号牙腾出空间，拔除了下颌对侧的14号牙。使用正畸装置将13号牙进一步移位至先前14号牙占据的位置，用11号牙替代12号牙，并将21号牙在牙弓中矫正到正确位置。
