Introduction
Various oblique views are helpful to reduce superimposition produced
using extra-oral standard views. The most common of these is the
technique detailed below, which can be used for both upper and lower
jaws. Standard textbooks also list various other views at different
angles.
Open Mouth 45° Lateral Oblique
This technique can be used for both the mandible and
the maxilla. The patient is in lateral recumbency and the mouth
fully opened with a non radio-opaque gag (foam wedge or syringe
barrel). The target area is nearest the film and the sagittal plane
is rotated 45° with a wedge.
