摘　　要：与根尖X线片、全景片或物理测量相比,锥形束CT(CBCT)分辨率高,成像不变形,且克服了根尖片测量时的放大失真问题,一次扫描即可得到全口资料,可提供轴位、矢状位、冠状位和3D图像。而与传统CT相比,CBCT扫描时间短,辐射剂量小。正确的测量牙齿长度、判断牙齿位置是口腔临床工作中必不可少的环节。目前,CBCT已应用于口腔医学各学科的临床和科研工作,不仅为疑难病例的解决提供了新途径,具有广泛的应用前景,还可以为口腔医学的教学和科研工作提供参考。Compared with periapical X-ray,panoramic radiographs or physical measurement,cone-beam computed tomography（ CBCT） has the features of high resolution imaging,no deformation,and has overcome the problem of distortion periapical measurement,and full oral information can be obtained through one scan,which can provide axial,sagittal,coronal and 3 D images. Compared with the traditional CT,the CBCT scanning time is short and the radiation dose is small. The correct measurement of the teeth length and the positioning of the teeth are essential parts of the oral clinical work. At present,CBCT has been applied to clinical and scientific research of various disciplines of stomatology. It not only provides a new way for solving difficult cases,but also has wide application prospects. It can also provide reference for teaching and scientific research of stomatology.
