title: Complications associated with inferior alveolar nerve repositioning for dental implant placement: a systematic review.
abstract: Inferior alveolar nerve (IAN) repositioning has been used widely in recent years as an alternative approach for dental implant placement in the atrophic posterior mandible. The aim of this study was to answer the question: What are the complications associated with IAN repositioning? A systematic literature review performed in accordance with the PRISMA statement, using the PubMed (MEDLINE), Cochrane Library, and Scopus databases, identified a total of 116 articles related to this technique. Of those articles, 24 were included in the final review. Lateralization was the chosen technique in seven studies, transposition in 15 studies, and two studies reported both techniques. The longest follow-up period was 49.1 months and the shortest 6 months. Of the patients who underwent lateralization, 95.9% initially showed a neurosensory disturbance, and the condition remained at the end of the study for 3.4% of those patients. With regard to the patients who underwent transposition, neurosensory alterations were observed in 58.9% of patients initially, and the condition remained for 22.1% of those affected at the end of the study. Only one study found no neurosensory disturbance at any time. More data consolidation is necessary to determine scientifically if, which, and when the IAN repositioning technique can be recommended.
