Assemble the appropriate instrument using the pictures on above
instruction picture as a guide. Most importantly be sure the
bite-block (film holder) is centered in the aiming ring.
Insert the desired size film in the bite-block. Slightly bend back
the vertical part of the holder and inert the film so that the film
edge sits on the bottom of the bite block. The vertical part will
return to its original position holding the film in place. Be sure
the correct side of the film faces the x-ray in the white side and
that the film is centered in the aiming ring.
Place the bite-block with the film into the patient's mouth as far
back as possible (the mid tongue area). Center the film on the
teeth to be x-rayed. Refer to the diagrams on the previous page for
placement. A cotton roll can be placed between the bite-block and
the opposite teeth to ensure the bite-block doesn't shift. Instruct
the patient to bite down to hold the instrument in place.
Position the patient by moving the chair or the patient's face to
allow you to comfortably bring the x-ray tube up to the instrument
for aiming ring. The RAPD instrument's indicator arm will be
parallel to the x-ray tube.
Expose the film and remove it for developing.
