Material and methods: Twenty patients underwent 20 coronectomy procedures of impacted mandibular third molar with close proximity to IAN evaluated
on preoperative radiographs. The procedure was performed under mandibular nerve block. Follow-up appointments were perform at 1 week, 1, 6 months.
Results: No patients developed IAN injury and no cases of root exposure were found. Eighteen wounds healed primary. In two cases the socket opened and
