%X <B>BACKGROUND: </B>Extraction of impacted third molars often leads to severe complications caused by damage to the inferior alveolar nerve (IAN).<BR><B>OBJECTIVE: </B>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.<BR><B>METHODS: </B>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.<BR><B>RESULTS: </B>All IMM3s were extracted easily without symptoms of IAN injury after extraction.<BR><B>CONCLUSIONS: </B>Partial IMM3 grinding may be a good alternative treatment option to avoid IAN injury in high-risk cases.
