This case report describes the successful orthodontic tooth movement through the maxillary sinus in an adult patient. A 41-year-old Asian woman had severe lip protrusion and multiple missing posterior teeth. Her orthodontic treatment included the extraction of 2 teeth, maximum retraction of the incisors using the extraction spaces and the existing spaces from the missing molars, and closure of all remaining spaces. Even though the treatment time was extended because of the anatomic and biologic challenges associated with moving posterior teeth over a long distance through the maxillary sinus, a successful outcome was obtained, with significant bone modeling of the maxillary sinus. The results demonstrate that a carefully selected force system can overcome the anatomic limitations of moving tooth against the cortical bone of the maxillary sinus wall in adult patients.
本病例报告描述了一例成年患者经上颌窦成功实现正畸牙齿移动。一位 41 岁的亚洲女性存在严重的嘴唇前突和多颗后牙缺失。她的正畸治疗包括拔除 2 颗牙齿，使用拔牙间隙和缺失磨牙的现有间隙最大程度内收切牙，并关闭所有剩余间隙。尽管由于将后牙通过上颌窦远距离移动所涉及的解剖和生物学挑战，治疗时间延长，但仍获得了成功的结果，上颌窦发生了显著的骨改建。结果表明，精心选择的力系统可以克服在成年患者中将牙齿对抗上颌窦壁皮质骨移动的解剖限制。
