Abstract

Introduction: Cone beam computed tomography (CBCT) is reliable in the assessment of structures related to teeth. The assessment of the inferior alveolar neurovascular (IAN) bundle location using CBCT is considered one of its prime uses in different mandibular surgeries.

Methodology: Retrospective CBCT data of patients presented to the institute were assessed to measure relations of IAN. Measurements were taken to assess the bone thickness adjacent to IAN, the superior-inferior dimension between the canal and the teeth, and the dimension between the canal and the inferior border of the mandible.

Results: Out of the 170 patients the root apices nearest to the IAN were that of the second molars (1.76 ± 1.86 mm). The IAN was closest to the inferior border of the mandible at the roots of the second molars (8 ± 3.4 mm). The buccal bone thickness had its greater dimension buccal to the IAN at the area of the second molar (5.16 ± 1.26 mm).

Conclusion: Two mini-plates in trauma do not increase the risk of injury. It is advisable in apicectomy not to extend 1.5 mm apically. The thickness of the nerve-lateralization window should not exceed 2 mm. In body osteotomy procedure, perform surgery anterior to premolars as much as possible.

下牙槽神经与下颌后牙关系的锥形束计算机断层解剖分析:回顾性影像学分析研究

简介锥形束计算机断层扫描（CBCT）是评估牙齿相关结构的可靠方法。使用 CBCT 评估下牙槽神经血管束（IAN）的位置被认为是其在不同下颌骨手术中的主要用途之一：方法：对到该研究所就诊的患者的 CBCT 数据进行回顾性评估，以测量 IAN 的关系。测量结果用于评估 IAN 附近的骨厚度、根管与牙齿之间的上下尺寸以及根管与下颌骨下缘之间的尺寸：在 170 名患者中，离 IAN 最近的根尖是第二磨牙的根尖（1.76 ± 1.86 mm）。第二磨牙根部的 IAN 最接近下颌骨下缘（8 ± 3.4 毫米）。颊骨厚度在第二磨牙区域的 IAN 颊侧最大（5.16 ± 1.26 mm）：结论：在创伤中使用两个迷你板不会增加损伤风险。在进行根尖切除术时，最好不要向根尖延伸 1.5 毫米。神经侧窗的厚度不应超过 2 毫米。在体部截骨术中，尽可能在前磨牙前方进行手术。
