Two patient therapies introduce the use of miniscrew anchorage in adult patients for the correction of mild to moderate occlusal plane canting without severe facial asymmetries. A miniscrew implanted in the infrazygomatic buttress was used as anchorage for intruding the overerupted maxillary quadrant. As unilateral intrusion of maxillary posterior teeth will develop a posterior unilateral open bite, box elastics were subsequently used to extrude the opposing teeth in the mandibular arch. These treatments show that miniscrew anchorage offers a simple, efficient method of correcting occlusal plane canting and mild facial asymmetries.
两种患者治疗方法介绍了在成年患者中使用微型螺钉支抗来矫正轻度至中度咬合平面倾斜且无严重面部不对称的情况。植入颧下支柱的微型螺钉用作压低上颌过度萌出象限的支抗。由于上颌后牙的单侧压低会导致单侧后牙开咬，随后使用盒形弹力牵引来压低下颌牙弓中的对颌牙。这些治疗表明，微型螺钉支抗为矫正咬合平面倾斜和轻度面部不对称提供了一种简单、有效的方法。
