Periapical ( PA ) - highlight only one or two teeth at a time.This includes every tooth, from crown to root to supporting structures.
Panoramic ( OPG ) - show the entire mouth on a single X-ray. They include all teeth on both upper and lower jaws. Devices attached to the X-ray machine hold your head and jaw in place. All this may look and feel intimidating, but the process is very safe. It often uses less radiation than intraoral X-rays.
3D Scan - provides you, as a dentist, with the most detailed information for a more accurate diagnosis and more precision in the treatment. 3D x-ray provides you with a more complete view of the facial anatomy - from almost every angle and perspective. What you would never see with 2D images.
