摘要 锥形束 CT (cone beam computerized tomography,CBCT)技术是锥形束容积体层成像技术或锥形束计算机断层扫描[1]。出现于20世纪90年代,是近年来开始应用于临床口腔疾病诊断的无创性影像方法[2],CBCT 不仅可以精确且快速观察到牙体及根尖组织细微结构,还能快速获得一个三维立体的牙重建结构。 CBCT 在口腔局部的成像功能更加有效,如在牙及牙周组织结构的成像方面比传统 CT 具有更多的优势[3],但是其在软组织成像上存在一些缺陷。 CBCT 可以同时对牙周围的骨缺损直接或间接地测量,特别是可以对牙体周围颊舌侧牙槽骨进行测量,从而了解牙周的骨量,并且使牙体周围的空间位置更形象化。这些都是传统的全景片与根尖片无法实现的。本文即利用 CBCT 的上述优点来分析临床上常见的2种口腔疾病。
