An Overlooked Advantage

Speed of acquisition with a direct sensor provides another great benefit which is almost never discussed. That is that the user can view the image before the sensor leaves the patient’s mouth.  If you miss the apex, cone cut the distal or overlap the interproximal you can see the error in seconds and make the necessary positioning adjustments to the sensor or the cone to get a perfect image.

With film you would not know about the problem until the film was processed and then you would have no physical reference point to return to improve the image.
