In this study 15 patients with abnormalities in dentition and jaws were analysed by computer tomography for the purpose of determining the diagnostic value of dental CT scanning in relation to orthodontic problems. The dental CTs were then compared with conventional panoramic x-rays. After describing principles and methodology, the study discusses the possibilities for clinical applications. The study demonstrated that dental CT scanning is definitely superior for diagnosing dentition disturbances, for metrical analysis of maxillary antrum relations, and for examining bony jaw structures. However, the routine use of dental CT scanning as a diagnostic method is at this time constrained due to the relatively high amount of time and labour the procedure requires with resulting implications for cost factors.
在本研究中，对15例牙列和颌骨异常患者进行了计算机断层扫描分析，目的是确定牙科CT扫描在正畸问题方面的诊断价值。然后将牙科CT与传统全景X线片进行比较。在描述了原理和方法之后，该研究讨论了临床应用的可能性。研究表明，牙科CT扫描在诊断牙列紊乱、对上颌窦关系进行测量分析以及检查颌骨结构方面绝对更具优势。然而，由于该程序需要相对较多的时间和人力，从而对成本因素产生影响，目前牙科CT扫描作为一种诊断方法的常规使用受到限制。
