Methods Nineteen bone impacted and unerupted teeth in 18 cases selected by orthopantomograph were scanned by 3DX-CT with 1.0 mm slice thickness. Images obtained by 3DX-CT (horizontally, sagittally, coronally) were analyzed after multi-plane reconstruction and 3D reconstruction including the angle of the bone axis impacted and unerupted teeth; maximum radius of the coronal teeth; distances between the tooth and the cortical bone around; distances to the neighboring tooth roots and nerve forum canal; the thickness of the bone tissue, etc.

对经曲面断层片筛选出的18例19枚埋伏牙进行牙科三维CT检查，扫描层厚1.0mm，重建后进行图像三维断面显示（包括水平位，矢状位，冠状位），对牙位图像进行分析及测量（包括埋伏牙牙长轴的角度，牙根弯曲度，牙冠的最大径，与骨皮质的距离，与邻牙根、神经孔／管的距离；骨质的厚度、高度等）。

Methods:①Make clinical scale of the magnitude of the tongue and the palate to the group of the OSAHS and the normal control②Successive scanning of the upper airway at the states of the normal inspiration and under the Müller action on both normal controls and the OSAHS patients with multi-slice spiral computed tomography. The scope of scanning was from the roof of nasopharynx to the level of hypohyal, bonding multiplate volume reconstruction,using the image workstation to survey the cross section area, sagittal diameter, coronal diameter on the soft tissue thickness in the lateral pharyngealwall and posterior wall of the pharynx, and the postzone of soft palate, uvula palatine ,tongue and epiglottis.
