Fig. 5. Illustration of the lingual nerve’s course in relation to the alveolar crest at the retromolar and molar regions of the lingual surface of the mandible. Majority of the nerves is located inferior to the alveolar crest during its course. The red line (①) represents the lingual nerve’s mean vertical location with reference to the alveolar crest, while the red zone represents the 95% confidence intervals. The distance between this zone and the alveolar crest is represented by the green arrows. This distance is the safety margin to the possible location of the lingual nerve at each landmark. A minority of the lingual nerves would course above the alveolar crest at the retromolar (8.8%) and a partially erupted third molar (6.3%) regions as represented by the orange line (②).
