Key Points

To compare the measurement differences of the mental foramen anatomical position before dental implant surgery between panoramic and three-dimensional cone beam computed tomography views.
Evaluated CBCT scans from 100 patients requiring dental implant placement.
Calculated vertical distance from the mandibular margin to the lower mental foramen border and horizontal distance from the mandibular symphysis to the mesial anterior border on both panoramic and 3D views.
Analyzed discrepancies between views using the Wilcoxon-rank U test with statistical significance set at P ≤ 0.05.
Horizontal distances differed significantly between panoramic and 3D views in dentate patients (22.7 ± 3.04 vs 21.1 ± 1.6 and 22.5 ± 2.4 vs 20.9 ± 1.5) and the left jaw across both sexes (22.4 ± 2.8 vs 21.2 ± 1.6 and 22.4 ± 2.8 vs 20.6 ± 1.4).
Vertical distances showed statistically significant discrepancies between panoramic and 3D views in dentate patients (12.1 ± 2.1 vs 11.1 ± 1.4 and 10.6 ± 1.4 vs 9.6 ± 1.3) and the left jaw (11.6 ± 1.95 vs 10.9 ± 1.2 and 10.5 ± 1.2 vs 9.96 ± 1.4).
No statistically significant measurement differences were observed between views in edentulous patients or along the right side of the jaw.
