In this case the clinical aim was to find aetiological evidence for the failure to erupt of the first mandibular molar on the right side. In order to enhance the 3D view, a combination of mild bone peeling, clipping and sculpting away part of the lingual cortical bone was executed (Animation 4.1 on this book’s website). Two additional animations (Animation 4.2 and Animation 4.3) will enhance the perception of the case. The latter animation shows how, by tilting the chin upwards (in the SW) and thereby placing the molar in a vertical position, animation becomes more informative (orthodontic treatment by Dr Ronen Zoizner).

The lesser density of the bone in the upper jaw makes the situation there much more favourable for obtaining good‐quality imaging of the impacted teeth, while maintaining tooth volume.

It is important to note that the 3D transparent view tends to deceptively show tooth volumes to be smaller than they are and, as such, should be treated with caution.
