This case report describes the use of a segmented appliance for space closure prior to using Invisalign. The maxillary right canine was retracted into the extracted first premolar space with a sectional wire from the first molar to the canine with no visible brackets in the incisor region. The advantage of this technique is the ability to achieve better root and rotational control during space closure with a fixed appliance that also has limited visibility. A maxillary fixed appliance was used to refine the esthetics in the maxillary arch due to the limitations of the Invisalign appliance in achieving rotational and vertical movements.
本病例报告描述了在使用隐适美之前，使用分段矫治器关闭间隙的情况。通过从第一磨牙到尖牙的分段弓丝，将上颌右侧尖牙牵入拔除的第一前磨牙间隙，切牙区无可见托槽。该技术的优点是，在使用固定矫治器关闭间隙时，能更好地控制牙根和扭转，且美观性受限较小。由于隐适美矫治器在实现扭转和垂直移动方面存在局限性，因此使用上颌固定矫治器来改善上颌牙弓的美观。
