OBJECTIVE
The most common diagnostic imaging modalities for cross-sectional imaging in dental implant planning are currently cone-beam computed tomography (CBCT) and multislice CT (MSCT). However, clinical differences between CBCT and MSCT in this task have not been fully clarified. In this investigation, the detection of fine anatomical structures in the mandible was assessed and compared between CBCT and MSCT images.
STUDY DESIGN
The sample consisted of 28 patients who had undergone CBCT and MSCT. The bifid mandibular canal in the mandibular ramus, accessory mental and buccal foramina, and median and lateral lingual bony canals were observed in 2-D images, and the findings were compared between CBCT and MSCT.
RESULTS
Four of 19 canals observed in CBCT were not observed in MSCT images. Three accessory mental foramina in 2 patients and 28 lateral lingual bony canals in 18 patients were observed consistently using the two methods.
CONCLUSION
Depiction of fine anatomic features in the mandible associated with neurovascular structures is consistent between CBCT and MSCT images.
目的
目前，在牙种植体规划中用于横断面成像的最常见诊断成像方式是锥形束计算机断层扫描（CBCT）和多层螺旋CT（MSCT）。然而，CBCT和MSCT在此任务中的临床差异尚未完全阐明。在本研究中，对CBCT和MSCT图像中下颌骨精细解剖结构的检测进行了评估和比较。
研究设计
样本包括28例接受过CBCT和MSCT检查的患者。在二维图像中观察下颌支中的双叉下颌管、副颏孔和颊孔以及舌侧正中管和舌侧外侧管，并比较CBCT和MSCT的观察结果。
结果
在CBCT中观察到的19条管道中有4条在MSCT图像中未观察到。使用两种方法一致观察到2例患者的3个副颏孔和18例患者的28条舌侧外侧管。
结论
CBCT和MSCT图像在下颌骨中与神经血管结构相关的精细解剖特征描绘方面是一致的。
