Abstract

Objective

This pilot study concerned evaluation of the success of predicted dental changes in patients presenting with Class I malocclusions who were submitted to treatment aligners, using the superimposition.

Methods

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.

Results

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.

Conclusions

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.

评估透明矫治器治疗预测牙齿变化的成功率：试点研究

方法使用 3DSlicer 5.0 软件对数字模型进行叠加和分析。对治疗和预测的水平和垂直线性位移、中轴旋转和切牙颊舌侧倾的变化进行量化。结果下切牙内陷是预测垂直位移中最准确的（86.96%），上犬齿的颊侧扩大（99.32%）和下切牙的中轴平移（98.57%）是最准确的水平线性位移。下门牙的预测旋转准确率最高（75.69%）。切牙颊舌向倾斜的成功率在 45.78 % 到 69.31 % 之间。上磨牙挤压（10.23 %）和收缩（8.91 %）的预测变化准确率较低。结论可以对上颌和下颌牙弓所有区域的牙齿变化进行评估。清创矫治器治疗计划中的大多数移动都有很高的成功率。
