Abstract
Background and Objectives: To determine the anatomic position of the inferior alveolar nerve (IAN) canal in patients with mandibular prognathismusing the cone-beam CT (CBCT).Materials and Methods: Fifty rami from 25 patients were evaluated. The images were taken by i-CAT and reconstructed 3-dimensionally using the Simplant 11 program. The linear distances between the IAN canal to the buccal cortex (a, a† and a†), from the IAN canal to the alveolar crest (b and b†) and the anterior margin (b†) and finally the buccal cortical thickness (c, c† and c†) were measured at three reference planes (VP, OP and HP). Results: On the left side, the average distance of a, b and c were 7.12, 15.96 and 3.60 mm on the VP plane, respectively. On the OP, the distance of a†, b† and c† was 6.11, 8.83 and 2.63 mm. For the HP, the distance of a†, b† and c† was 4.84, 10.11 and 2.30 mm. On the right side, the distance of a, b and c, on the VP, was 7.10, 16.13 and 3.42 mm, respectively. On the OP, the distance of a†, b† and c† was 4.77, 8.75 and 2.68 mm. On the HP, the distance of a†, b† and c† was 4.55, 9.84 and 2.38 mm. Regarding the difference between genders, the distance in male’s was longer than female’s on the VP (p=0.019), and was thicker in males than females on the HP (p=0.002). Conclusion: The CBCT data provided accurate information about the location and course of the IAN.
