8.5.2 Parallel technique
With this technique, the surface of the film is positioned parallel to the
tooth’s axis. Due to anatomic factors, the film is kept far from the lingual
surface of the tooth in general, with the exception of molars.
When the film is introduced into the patient’s mouth, it is fixed on a
support to prevent distortion. The patient holds the support with his
teeth.
Various types of supports are available on the market that can be
adapted to different types of teeth. This technique makes it easier to
obtain more accurate and repeatable X-rays than with the bisector
technique (see Figure 19 and Figure 20).
