UNASSIGNED: The digital models were superimposed and analyzed using 3DSlicer 5.0 software. Treatment and predicted changes regarding horizontal and vertical linear displacements, mesiodistal rotations, and incisor buccolingual tipping were quantified. The success rates were calculated by dividing the mean treatment change amount by the predicted change amount.
UNASSIGNED: Lower-incisor intrusion was the most accurate of the predicted vertical displacements (86.96 %), and buccal expansion of upper canines (99.32 %) and mesial translation of the lower incisors (98.57 %) were the most accurate horizontal linear displacements. The predicted rotation was achieved with the highest accuracy for lower incisors (75.69 %). Incisor buccolingual tipping success rates ranged between 45.78 % and 69.31 %. Low accuracy of predicted changes was found for upper-molar extrusion (10.23 %) and constriction (8.91 %). However, minimal corrections in these directions were planned.
UNASSIGNED: Dental changes for all regions of maxillary and mandibular arches could be evaluated. High success rates were observed for most of the movements planned for ClearCorrect aligner therapy.
将数字模型叠加并使用3DSlicer5.0软件进行分析。关于水平和垂直线性位移的治疗和预测变化,中远端旋转,和门牙颊舌倾翻进行量化。通过将平均治疗变化量除以预测的变化量来计算成功率。
■下切牙侵入是预测的垂直位移中最准确的(86.96%),上犬齿的颊扩张(99.32%)和下切牙的内侧平移(98.57%)是最准确的水平线性位移。下切牙的预测旋转精度最高(75.69%)。切牙颊舌翻倒成功率在45.78%至69.31%之间。发现上摩尔挤压(10.23%)和收缩(8.91%)的预测变化精度较低。然而,计划在这些方向上进行最小的校正。
■可以评估上颌和下颌弓所有区域的牙齿变化。对于计划用于ClearCorrect对准器治疗的大多数运动,观察到了很高的成功率。
