摘要： 目的: 研究微种植钉和铸造支架直接牵引上颌第二、第三磨牙前移关闭上颌第一磨牙缺隙的临床疗效。方法: 选择12例上颌第一磨牙缺失,且只接受局部正畸治疗的患者为研究对象。在腭中缝两侧植入微种植支抗钉2颗,制作铸造支架,稳定连接上颌同侧前磨牙和微种植钉。设计力线接近阻抗中心,颊舌侧加力牵引磨牙近中移动,关闭间隙。采用Graphpad Prism 6.0 软件包对所得数据进行配对t检验。结果: 所有间隙均顺利关闭,磨牙近中平均移动5.7 mm,磨牙轴倾度基本正常,牙周状况良好,其余牙保持原有咬合关系。结论: 利用微种植钉和铸造支架可以有效牵引上颌第二、第三磨牙近中移动,关闭上颌第一磨牙缺隙。

Abstract: PURPOSE: To study the clinical effect of the upper first molar space closure by mesial traction of the second and the third molar with palatal miniscrew and casting frame. METHODS: Twelve cases with the upper first molar lost and only accepting regional orthodontic treatment were chosen. Two miniscrews were inserted beside the palatal suture, individual casting frames were manufactured to help stabilize the miniscrew and the upper premolars on the same side. The force was exerted on both the buccal and lingual side. Graphpad Prism 6.0 software was used for Student's t test. RESULTS: All the spaces were closed, the average mesial movement was 5.7 mm, the tipping of the second molar and the third molar was almost normal and the occlusion of other teeth kept intact. CONCLUSIONS: Miniscrew and casting frame can accomplish the effective mesial movement of the upper second and third molar to close the first molar space.

Key words: Miniscrew, Casting frame, Space closure
