In the paralleling technique, the image receptor must be placed parallel to the long axis of the tooth being imaged. For most areas, the patient bites down on the bite block as far away from the teeth as possible to achieve this parallelism. However, for the maxillary anteriors, due to the palatal anatomy and the need to avoid superimposition of the palatal roots and to ensure the image receptor is parallel to these teeth, the exception is made.
