摘要

一位27岁的成年女性以双侧下颌第一磨牙缺失为主诉，强烈倾向于使用智齿而不是假体置换。使用圆形澳大利亚金属丝固定正畸技术进行治疗。第二磨牙和第三磨牙采用双侧末端螺旋环结合弯曲的澳大利亚金属丝近端移动。在下颌前磨牙区放置微型支抗，辅助第二、第三磨牙的拔除。此外，采用改良的皮质钻孔技术来加速牙齿的运动。在保持患者面部轮廓的同时，建立了中性磨牙关系。

Mandibular molar protraction using round Australian wire and miniscrew anchorage with modified corticision in an adult with first molar loss: A case report

A 27-year-old adult female presented with the chief complaint of bilateral mandibular first molar absence and strongly preferred to use wisdom teeth rather than prosthetic replacements. Treatment was carried out using a round Australian wire fixed orthodontic technique. The second and third molars were mesially moved with a bilateral terminal helical loop combined with curved tip-back bends in Australian wire. Miniscrew anchorage was placed in the mandibular premolar area to assist in the protraction of the second and third molars. Additionally, a modified cortical drilling technique was employed to accelerate tooth movement. A neutral molar relationship was established while maintaining the patient's facial profile.
