The inferior alveolar nerve has an anterior ramification with two terminal branches, the mental nerve and the anterior plexus (or "incisor nerve"). The mental nerve is described to have a superior, lateral, and posterior course formed as a loop. The length of the loop is reported to be between 3 and 7 mm. In the present study, dissection of the ramification of the inferior alveolar neurovascular bundle was performed unilaterally in 58 patients. In 43 cases the loop was 1.0 mm long. In addition, the anatomy of the ramification with the mental and incisor canals frequently diverged in other respects from prevalent descriptions in the literature.
下牙槽神经有一个前支，其有两个终末分支，即颏神经和前丛（或“切牙神经”）。颏神经被描述为呈袢状走行，有向上、向外和向后的行程。据报道，袢的长度在3至7毫米之间。在本研究中，对58例患者进行了单侧下牙槽神经血管束分支的解剖。在43例中，袢长1.0毫米。此外，颏管和切牙管分支的解剖结构在其他方面也常常与文献中的普遍描述不同。
