The aim of this retrospective study was to evaluate the incidence of inferior alveolar nerve (IAN) lesion and duration of sensitivity disturbances after the insertion of dental implants.
One thousand sixty-five patients (mean age: 58.9 years) enrolled between February 2004 and July 2015 with partial or full mandibular edentulism were selected to receive dental implants for oral rehabilitation. A total of 3025 implants were placed. After surgical procedures, controls were scheduled at suture removal, that is, 10 days after surgery, and repeated at intervals of 1, 3, and 6 months, and comprised patient interview, clinical examination, and sensitivity tests.
Only 23 (2.2%) of the 1065 patients presented sensitivity disturbances 1 month after implant insertion, and only 2 (0.19%) after 6 months, though a complete recovery was observed in these patients within 13 months.
Considering the debilitating effects resulting from IAN lesion and the complexity of the therapeutic diagnostic protocols, all patients undergoing oral rehabilitation through dental implants should be evaluated with CBCT imaging.
本回顾性研究旨在评估下颌神经（IAN）损伤的发生率和种植体植入后感觉障碍的持续时间。
选择 2004 年 2 月至 2015 年 7 月期间患有部分或完全下颌牙列缺失的 1065 名患者（平均年龄：58.9 岁）接受种植牙进行口腔修复。共植入 3025 枚种植体。手术后，在拆除缝线时（即术后 10 天）进行对照，然后每隔 1、3 和 6 个月重复一次，包括患者访谈、临床检查和感觉测试。
仅 23 名（2.2%）1065 名患者在植入后 1 个月出现感觉障碍，6 个月后仅 2 名（0.19%）出现感觉障碍，但这些患者在 13 个月内完全恢复。
考虑到 IAN 损伤引起的致残影响和治疗诊断方案的复杂性，所有接受种植牙口腔修复的患者都应进行 CBCT 成像评估。
