For a mandibular image:
1 Have the patient draw the tongue towards the back of the mouth. Insert the sensor holding it
horizontally.
2 Then turn the sensor downward to place it in a vertical position.
3 Center the sensor on the targeted tooth slide it distally, and ask the patient to push the
tongue to the opposite side. Do not hesitate to compress the mucous membranes to properly
frame the apical area. The patient can then relax the tongue, to allow the sensor to fit
naturally. For premolars and incisors, move the sensor towards the center of the mouth by
compressing the tongue when the mouth closes to relax the muscles.
For a maxillary image:
1 Insert the sensor, maintaining it horizontally.
2 Turn the sensor upward so that it is vertical or parallel to the axis of the targeted tooth.
3 Center the sensor on the tooth to be X-rayed by sliding it distally. Do not hesitate to use the
roundness of the palatal arch and place the sensor at the center of the cavity.
