Tracing the inferior alveolar and marking it in red is a helpful feature. Once marked, it is embedded in the volume and will show as a red dot or line in any cut that crosses its path. This method is used principally in planning the placement of dental implants. However, for much the same reason, it has value in respect of the inter‐relations between the inferior dental (ID) canal and a severely and deeply infra‐occluded/impacted molar or premolar, whose roots are developing in close proximity to it (Figure 4.20 and Case 5).

Fig. 4.19 Multi‐planar reconstruction for an incisor that is almost horizontal. The right central incisor was horizontally and sagitally re‐aligned in the axial (a) and sagittal (b) planes and the centre of the rotating tool is placed on its long axis in the coronal window (c). Window (d) represents the cut produced by the rotating tool, in which the contact point with the lateral incisor is demonstrated.
