The purpose of this study was to evaluate differences in three-dimensional (3D) morphology of the hard palate between Korean adults with and without mild-to-moderate obstructive sleep apnea (OSA) using cone-beam computed tomographic (CBCT) data.
The protocol for the two-dimensional (2D) and 3D mathematical modeling was established by analyzing CBCT images of 30 adults with OSA and 30 matched controls without OSA, using MIMICS software. The linear and angular measurements were also determined using this software. The measurements were repeated for 30 palates, by the same operator, to assess reliability.
The palates of OSA patients were higher in the posterior part and narrower in the anterior-superior part than those of the control group ( < 0.05). The nasal cavities of patients with OSA were narrower ( < 0.05) than those of controls. The increasing angle of the first molar palatal root is a compensation of the upper dental arch to improve occlusion. However, for most palatal measurements, there were no significant differences between the OSA and control groups ( > 0.05). The results of 2D and 3D mathematical models were consistent for linear and angular measurements, indicating that 2D and 3D mathematical modeling of the palate is a reliable methodology.
OSA is a multifactorial disease; the palates of adults with mild-to-moderate OSA do not have specific morphological features distinct from those of healthy controls.
本研究旨在利用锥形束计算机断层扫描（CBCT）数据，评估患有和未患有轻至中度阻塞性睡眠呼吸暂停（OSA）的韩国成年人硬腭的三维（3D）形态差异。
通过使用MIMICS软件分析30名患有OSA的成年人和30名匹配的无OSA对照组的CBCT图像，建立二维（2D）和3D数学模型的方案。还使用该软件确定线性和角度测量值。由同一名操作人员对30个腭进行重复测量，以评估可靠性。
与对照组相比，OSA患者的腭后部更高，前上部更窄（<0.05）。OSA患者的鼻腔比对照组更窄（<0.05）。第一磨牙腭根角度的增加是上牙弓的一种补偿，以改善咬合。然而，对于大多数腭部测量，OSA组和对照组之间没有显著差异（>0.05）。二维和三维数学模型的线性和角度测量结果一致，表明腭部的二维和三维数学建模是一种可靠的方法。
OSA是一种多因素疾病；轻至中度OSA成年人的腭部没有与健康对照组不同的特定形态特征。
