Abstract：
BACKGROUND: Extraction of impacted third molars often leads to severe complications caused by damage to the inferior alveolar nerve (IAN).
OBJECTIVE: To proposes a method for the partial grinding of an impacted mandibular third molar (IMM3) near the IAN to prevent IAN injury during IMM3 extraction.
METHODS: Between January 1996 and March 2022, 25 patients with IMM3 roots near the IAN were enrolled. The first stage of the operation consisted of grinding a major part of the IMM3 crown with a high-speed turbine dental drill to achieve sufficient space between the mandibular second molar and IMM3. After 6 months, when the root tips were observed to be away from the IAN on X-ray examination, the remaining part of the IMM3 was completely removed.
RESULTS: All IMM3s were extracted easily without symptoms of IAN injury after extraction.
CONCLUSIONS: Partial IMM3 grinding may be a good alternative treatment option to avoid IAN injury in high-risk cases.

摘要：
背景：拔除阻生第三磨牙通常会导致下牙槽神经（IAN）损伤引起的严重并发症。
目的：提出一种对IAN附近的下颌阻生第三磨牙（IMM3）进行部分研磨的方法，以防止IMM3拔除过程中的IAN损伤。
方法：在1996年1月至2022年3月之间，招募了25例IMM3靠近IAN的患者。手术的第一阶段包括用高速涡轮牙钻研磨IMM3牙冠的主要部分，以在下颌第二磨牙和IMM3之间获得足够的空间。六个月后,当在X射线检查中观察到根尖远离IAN时，IMM3的剩余部分被完全移除.
结果：所有IMM3均可轻易提取，提取后无IAN损伤症状。
结论：部分IMM3研磨可能是避免高危病例IAN损伤的良好替代治疗选择。
