摘要/Abstract

摘要： [摘要] 目的利用锥形束CT（cone beam computed tomography, CBCT）成像技术，研究下颌神经管的结构、位置及分支。方法收集160正常人群的CBCT下颌骨扫描数据，观测下颌神经管在下颌体的位置、下颌神经管在下颌第三磨牙至颏孔之间的分支情况、与下颌后牙的三维位置关系。结果下颌神经管从第三磨牙到第二前磨牙的直径平均为2.98mm。9.38%下颌神经管出现前襻，平均深度在12.86mm以下。7.5%的第三磨牙与下颌管接触，当下颌管位于下颌第三磨牙舌侧位时，下颌管与其相接处触概率较高。下颌神经管中分支率28.44%。结论 CBCT影像有助于确定下颌管的结构、位置及分支，可避免或减少治疗中的下颌神经受损。

Abstract: Abstract: Objective To study the structure, position and bifid of the mandibular canal by CBCT image. Methods CBCT data of 160 people were collected, and mandibular canal position in mandible, bifid from third molar to mental foramen, and three dimensional relation with the posterior teeth were analyzed. Results The average diameter of mandibular canal was 2.98mm from third molar to second premolar. Anterior loop appeared in 9.38% mandibular canal, and the average depth is 12.86mm. Mandibular canal contacted with 7.5% third molars, and the rate is higher when canal located lingually to the third molar. 28.44% mandibular canals have bifids. Conclusion CBCT image can help to observe the the structure, position and bifid of the mandibular canal, and avoid or reduce the nerve damage in treatment.
