Abstract

: Objectives: the aim of this study was to evaluate the effect of modified mini-implant aided trans-palatal arch on maxillary molar distalization using CBCT. Methods: 10 adult patients with Angle class II molar relation were submitted to maxillary first molar distalization using modified mini-implant aided trans palatal arch (MIA-TPA), after completing the essential orthodontic records, CBCT was taken before distalization at T0, then trans-palatal arch (TPA) of 1mm diameter passing anterior on the palate was cemented and 2 miniscrews were inserted between the maxillary 2nd premolar and 1st molar on the palatal side. NiTi closed coil spring was applied between TPA anterior and mini- implant to produce distalization force of 250g/side parallel to the occlusal plane. Dental changes of maxillary molars were compared using cone beam computed tomography CBCT after achieving class I molar relation at T1. Results: According to the dental linear and angular measurements, the maxillary first molar showed statistically significant bodily distal movement without significant distal tipping. Vertically, the maxillary first molar showed statistically significant intrusion. Conclusion: MIA-TPA

改良微型种植体辅助跨腭弓对上颌磨牙离体的CBCT评价

目的:利用CBCT评价改良的微型种植体辅助跨腭弓对上颌磨牙远端的影响。方法:对10例有Angleⅱ类磨牙关系的成人患者，采用改良的微型种植体辅助经腭弓(MIA-TPA)进行上颌第一磨牙远端，在完成必要的正畸记录后，于T0时行CBCT检查，然后将直径为1mm的经腭弓(TPA)通过上颌前牙，在上颌第二前磨牙和腭侧第一磨牙之间置入2枚微型螺钉。在TPA前牙与微型种植体之间施加NiTi封闭线圈弹簧，产生平行于咬合面250g/侧的远端力。在T1达到I级磨牙关系后，采用锥形束ct (CBCT)对上颌磨牙的变化进行比较。结果:上颌第一磨牙的线性和角度测量结果显示，上颌第一磨牙的躯体远端运动有统计学意义，未见明显的远端倾斜。在垂直方向上，上颌第一磨牙有统计学意义上的侵入。结论:MIA-TPA
