摘要:
目的：通过锥形束CT（Cone beam computed tomography,CBCT）测量分析微种植体支抗整体远中移动上牙列正畸治疗 前后上气道的变化及牙弓的三维变化，并分析两者之间的相关性。方法：选择23例使用微种植支抗整体远中移动上牙列的正 畸治疗患者，拍摄矫治前后的CBCT影像，使用Dolphin Image 11.9软件重建三维图像，根据上颌骨固有解剖标志点建立三维 坐标系，测量分析治疗前后上气道总体积、鼻咽腔体积、口咽腔体积及口咽腔最小横截面积变化，上切牙内收量、牙弓宽度 变化量以及牙合平面旋转角度变化。分析前后上气道变化与牙齿变化量之间的相关性。结果：患者治疗前后上气道总体积、鼻 咽腔体积、口咽腔体积及口咽腔最小横截面积变化差异无统计学意义。术后上切牙矢状向位置、尖牙、磨牙宽度、牙合平面角 度与术前相比有显著性差异，术后牙合平面发生顺时针旋转。未测得治疗前后上气道变化量与上牙弓变化量之间的相关性。结 论：微种植支抗整体远中移动上牙列不会改变上气道尺寸，上气道体积及最小横截面积变化与上前牙内收量、牙弓宽度变化 量以及牙合平面角度变化量不相关。
Abstract:
Objective The purpose of this study was to measure and analyse the three-dimensional (3D) changes of the upper airway and dental arch together with the correlation between them through cone beam computed tomography (CBCT) before and after the maxillary dentition distalization with microimplant anchorage. Methods Twenty-three patients treated by distalizing the whole maxillary dentition with microimplant anchorage were selected, whose CBCT images were taken before and after the treatment. Dolphin Image 11.9 software was used to reconstruct the 3D images, and 3D coordinate system was established according to the maxillary intrinsic anatomical landmarks. The total upper airway volume, the nasopharyngeal volume, the oropharyngeal volume and minimum oropharyngeal cross-sectional area were measured. The retraction of maxillary incisors, the changes of dental arch width, as well as the occlusal plane angle were also measured. The correlations between them were analyzed. Results There were no significant changes in the total volume of upper airway, nasopharyngeal volume, oropharyngeal volume and minimum oropharyngeal cross-sectional area before and after treatment. The sagittal position of the maxillary incisors, the canine and molar widths and the occlusal plane angle were significantly changed, and the occlusal plane was rotated counterclockwise. No correlation was found between changes in the upper airway and the dental arch. Conclusion Distalization of the whole maxillary dentition with microimplant anchorage would not significantly change the size of the upper airway. There was no correlation among the changes of upper airway volume, minimum oropharyngeal cross-sectional area and the changes of sagittal position of the maxillary incisors, the dental arch widths and the occlusal plane angle
