摘要/Abstract

摘要： 目的: 通过CBCT测量种植支抗整体远中移动上牙列正畸治疗后牙齿三维方向的变化,评价其移动方式及力学机制。方法: 筛选满足纳入标准的23例种植支抗整体远中移动上牙列正畸成人患者,用Dolphin软件测量治疗前后牙齿三维方向上的变化,运用SPSS 23.0软件对其进行统计分析。结果: 上颌第一磨牙、尖牙、切牙远中移动量分别为2.60 mm、2.66 mm、2.07 mm,远中倾斜角度分别为5.31°、5.42°、-4.68°。上颌第一磨牙颊尖和尖牙分别压低0.96 mm、0.40 mm。牙合平面顺时针旋转1.51°。第一磨牙颊向倾斜4.57°,远中旋转7.71°。尖牙区和磨牙区宽度分别增加1.18 mm、2.01 mm。结论: 采用种植体支抗整体远移上牙列可以获得有效的远中移动量,远移的磨牙存在一定程度的压低、远中倾斜及远中扭转,上颌牙合平面发生顺时针旋转,尖牙区和磨牙区的宽度增加。

Abstract: Objective: To measure the three-dimensional changes of the teeth after upper arch distalization with mini-screw anchorage using CBCT, and evaluate its movement mode and mechanical mechanism. Methods: 23 patients who underwent distalization of maxillary dentition with mini-screw anchorage were included. The three-dimensional changes of teeth were analyzed by Dolphin software. SPSS 23.0 was used for analysis of the changes. Results: The mean distalization values of upper first molar, canine, and incisor were 2.60 mm, 2.66 mm, and 2.07 mm. Mean distal tipping of upper first molar, canine, and incisor were 5.31°, 5.42° and -4.68°. The mean extrusion values of upper first molar and canine were 0.96 mm and 0.40 mm. The occlusal plane showed significant clockwise rotation by 1.51°. The upper first molar showed 4.57° buccal tipping and 7.71° distal rotation. The widths of upper canine and first molar increased 1.18 mm and 2.01 mm on average. Conclusion: Significant distalization of upper arch could be obtained by mini-screw anchorage.Upper molar showed a certain degree of extrusion, buccal tipping, and distal rotation. The occlusal plane showed significant clockwise rotation. The width of the upper canine and first molar increased.
