This study aimed to evaluate the reliability of 3D-TMT, previously used only for dynamic testing, in a static cephalometric evaluation. A group of 40 patients (20 males and 20 females; mean age 14.2 ± 1.2 years; 12-18 years old) was included in the study. The measurements obtained by the 3D-TMT cephalometric analysis with a conventional frontal cephalometric analysis were compared for each subject. Nine passive markers reflectors were positioned on the face skin for the detection of the profile of the patient. Through the acquisition of these points, corresponding plans for three-dimensional posterior-anterior cephalometric analysis were found. The cephalometric results carried out with 3D-TMT and with traditional posterior-anterior cephalometric analysis showed the 3D-TMT system values are slightly higher than the values measured on radiographs but statistically significant; nevertheless their correlation is very high. The recorded values obtained using the 3D-TMT analysis were correlated to cephalometric analysis, with small but statistically significant differences. The Dahlberg errors resulted to be always lower than the mean difference between the 2D and 3D measurements. A clinician should use, during the clinical monitoring of a patient, always the same method, to avoid comparing different millimeter magnitudes.
本研究旨在评估三维颞下颌关节断层扫描（3D-TMT）在静态头影测量评估中的可靠性，此前该技术仅用于动态测试。本研究纳入了一组40例患者（20例男性和20例女性；平均年龄14.2±1.2岁；年龄在12至18岁之间）。对每个受试者进行3D-TMT头影测量分析与传统正位头影测量分析所获得的测量结果进行比较。在面部皮肤上放置九个被动标记反射器以检测患者的面部轮廓。通过采集这些点，找到相应的三维后前位头影测量分析计划。3D-TMT和传统后前位头影测量分析的头影测量结果显示，3D-TMT系统的值略高于在X线片上测量的值，但具有统计学意义；然而它们的相关性非常高。使用3D-TMT分析获得的记录值与头影测量分析相关，差异虽小但具有统计学意义。达尔伯格误差始终低于二维和三维测量之间的平均差异。临床医生在对患者进行临床监测时应始终使用相同的方法，以避免比较不同的毫米量级。
