本文报道了一名 15 岁 8 个月的 III 类错牙合畸形和少牙患者的成功治疗；治疗期间使用钛螺钉进行绝对锚固。由于下颌骨过度且两个牙弓空间不对称，患者的轮廓呈凹形。口内升支垂直截骨联合LeFort I截骨术在磨牙后区植入钛螺钉。绝对支抗是通过从螺钉延伸至左侧尖牙和右侧切牙的支抗线来提供的。正畸间隙闭合后，下颌磨牙向近中移动，下颌切牙不舌侧倾斜。实现了良好的切际关系。我们的结果表明，磨牙后区域的钛螺钉和支抗钢丝对于下颌磨牙的近中移动很有用。
This article reports the successful treatment of a patient, aged 15 years 8 months, with a Class III malocclusion and oligodontia; a titanium screw was used for absolute anchorage during treatment. The patient had a concave profile because of mandibular excess and asymmetric spaces in both arches. Titanium screws were implanted in the retromolar area during intraoral vertical ramus osteotomy combined with LeFort I osteotomy. Absolute anchorage was provided with anchorage wires extending from the screws to the left canine and the right lateral incisor. After orthodontic space closure, the mandibular molars were moved mesially without lingual tipping of the mandibular incisors. A good interincisal relationship was achieved. Our results suggest that titanium screws and anchorage wires in the retromolar area are useful for the mesial movement of mandibular molars.
