This technical note aims to present the fabrication and application of a new generation of posterior intrusion appliances using zygomatic anchorage. The use of zygomatic anchorage enables en masse impaction of the posterior segment without any side effects such as labial flaring. A 14-year-old, female Class II patient with an anterior open bite was treated with a new generation posterior intrusion appliance. At the end of treatment, a Class I canine and molar relationship and a correction of the anterior open bite were achieved. The molars were impacted 3.6 mm, and this impaction was maintained throughout the treatment. The mandibular plane showed a counterclockwise autorotation of 4 degrees. This case report demonstrates that zygomatic anchorage can be used effectively for molar intrusion and anchorage maintenance. However, further clinical studies with larger samples are required to confirm its effectiveness.
本技术说明旨在介绍使用颧骨锚固的新一代后牙侵入矫治器的制作及应用。颧骨锚固的使用能够实现后牙段的整体压低，且不会产生诸如唇侧扩弓等副作用。一名14岁的安氏II类错颌女性患者，伴有前牙开颌，采用新一代后牙侵入矫治器进行治疗。治疗结束时，实现了I类尖牙及磨牙关系，并矫正了前牙开颌。磨牙压低了3.6毫米，且在整个治疗过程中保持该压低效果。下颌平面呈现4度的逆时针自动旋转。本病例报告表明，颧骨锚固可有效用于磨牙压低及支抗维持。然而，需要进一步开展更大样本量的临床研究以证实其有效性。
