Acquiring a Good Image

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. The rigidity of the sensor and the
positioning system aids in obtaining the image.
Positioning the Sensor for a Maxillary
Image
To position the sensor for a maxillary image, follow
these steps:
1. Insert the sensor, maintaining it horizontally.
2. Turn the sensor upward so that it is vertical or
parallel to the axis of the target 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.
