目的

评价用片段弓联合微种植体支抗直立倾斜磨牙临床效果。

方法

选择24 例(28 颗)邻牙缺失磨牙近中倾斜的患者,使用片段弓联合微种植体支抗直立倾斜磨牙,通过模型测量评价疗效。

结果

治疗后第一磨牙磨牙水平移位(1.92±0.98) mm,近中倾斜角减小(20.67 ±5.14)°;第二磨牙水平移位(2.60±1.09) mm,近中倾斜角减小(25.36±6.57)°,均有明显的竖直效果。

结论

片段弓联合微种植体支抗直立倾斜磨牙是一种简便、舒适、有效的方法。

Objectives

To evaluate the clinical effect of uprighting the tilting molars with the application of segmental arch and micro-implant anchorage.

Methods

Twenty-four cases (28 tilting molars) with mesially inclined molars were treated corrected with segmental arch and micro-implant anchorage to upright the tilting molars. The clinical effect was evaluated by modal examination.

Results

Tilting molars presented a significant effect of uprighting after treatment. The first molar showed a horizontal shift of (1.92 ± 0.98) mm and mesially inclined angle was decreased by(20.67 ± 5.14)°. The second molar showed a horizontal shift of (2.60 ± 1.09) mm and mesially inclined angle was decreased by (25.36 ± 6.57)°.

Conclusions

The application of segmental arch and micro-implant anchorage is a simple, comfortable, effective method for uprighting the tilting molars.
