ARTICLE HIGHLIGHTS
Research background
The conventional method of extracting impacted mandibular third molars (IMM3) that are closely related to the inferior alveolar nerve (IAN) can easily damage the nerve.
Research motivation
To avoid damaging the IAN during tooth extraction.
Research objectives
To proposes a method for the partial grinding of an IMM3 near the IAN to prevent IAN injury during IMM3 extraction.
Research methods
The first stage was to use a high-speed turbo drill to grind and cut most of the IMM3 dental crowns, leaving the roots in place. After 6-12 months, when the IMM3 root left the nerve canal, complete extraction of the IMM3 root was performed.
Research results
Although it seemed to take longer after two stages, all IMM3s were completely removed, and there were no cases of complications of damaging the IAN.
Research conclusions
Two-stage extraction of IMM3 located closer to the IAN canal can minimize nerve damage to the greatest extent possible.
Research perspectives
Partial IMM3 grinding may be a good alternative treatment option to avoid IAN injury in high-risk cases.
