A common dilemma in adult orthodontic treatment is deciding how best to treat missing posterior teeth. One treatment option is to orthodontically close the space. But closure can be difficult, especially if the open space is in the maxillary posterior area, because tooth movement through the maxillary sinus is limited. The increased difficulty of moving teeth in the maxillary sinus is similar to moving a tooth in the atrophic posterior mandibular ridge. If space closure is selected as a treatment method, proper mechanics and light forces should be applied. In this article, we report movement of teeth through the maxillary sinus and discuss various implications related to orthodontic treatment in the maxillary sinus.
成人正畸治疗中的一个常见难题是决定如何最好地治疗缺失的后牙。一种治疗选择是通过正畸关闭间隙。但关闭可能很困难，特别是如果开放间隙在上颌后区，因为上颌窦内牙齿移动受到限制。在上颌窦内移动牙齿的难度增加类似于在萎缩的下颌后牙槽嵴内移动牙齿。如果选择关闭间隙作为治疗方法，应施加适当的力学和轻力。本文报告了牙齿通过上颌窦的移动，并讨论了与上颌窦正畸治疗相关的各种影响。
