目的:观察单侧微螺钉种植体配合固定矫治器纠正成人中线偏斜的临床效果。方法:选择临床确诊的成人中线偏斜1例,采用微螺钉种植体支抗作为强支抗,利用滑动法直接将上颌12颗牙向远中整体移动。结果:经过3个月矫治后,患者双侧磨牙中性关系,尖牙尖窝相对,前牙覆颌覆盖正常,上下中线对齐上唇珠,中线整体向右侧移动5mm。结论:单侧微螺钉种植体配合固定矫治器是纠正成人中线偏斜的理想方法。
Objective: To observe the clinical effect of unilateral micro-screw implants with fixed appliance to correct the midline skew in adults. Methods: One case of clinically diagnosed adult midline skew was selected. Micro-screw implant anchors were used as strong anchors. Sliding method was used to directly move maxillary maxillary teeth 12 to the middle. Results: After 3 months of orthodontic treatment, the bilateral molars had a neutral relationship with a sharp canine spine. The anterior teeth covered the upper jaw properly and the upper and lower center lines aligned with the upper lip. The median line shifted to the right by 5mm. Conclusion: Unilateral micro-screw implants with fixed appliance is the ideal method to correct the adult midline skew.
