摘要: 目的：用锥形束CT(CBCT)进一步评估在曲面体层片中表现为下颌第三磨牙和下颌管影像重叠时二者的三维解剖关系，以此预测下颌第三磨牙拔除过程中下颌管损伤的风险。方法：对在曲面体层片中表现为下颌第三磨牙和下颌管影像重叠的患者行CBCT检查，运用软件(Plameca Romexis 3.8.3.R)对所得图像测量分析，通过SAS 10.0软件对所得数据进行X2检验。结果：当全面体层中表现为下颌第三磨牙和下颌管影像重叠时，骨白线是否中断与两者是否接触存在相关性。结论：CBCT与曲面体层片相比，可以更准确地反映下颌第三磨牙与下颌管的三维解剖关系，预判拔除风险。
Abstract: Objective: CBCT was used to further evaluate the 3D anatomical relationship between the MTM and the MC overlap in the OPG to predict the risk of MC injury during MTM extraction. Methods: CBCT examination was performed on patients who showed MTM and MC image overlap in OPG, and the obtained images were measured and analyzed by software (Plameca Romexis 3.8.3.R), and the obtained data were subjected to X2 test by SAS 10.0 software. Results: When the OMG appears to overlap the MTM and MC images, there is a correlation between whether the bone white line is interrupted or not. Conclusion: Compared with OPG, CBCT can more accurately reflect the 3D ana-tomical relationship between MTM and MC, and predict the risk of extraction.
