An Orthopantomogram, or OPG, is a special type of x-ray that looks at the lower face, teeth, jaw joints and maxillary sinuses. The teeth are displayed in a long flat line. This x-ray is useful to demonstrate the number of teeth as well as their position and growth, and is particularly useful to assess teeth that have not yet surfaced.
What is Lateral Cephalogram ?
A Lateral Cephalogram (or Lat Ceph) is an x-ray taken of the side of the face with very precise positioning, so that various measurements can be made to determine the current and future relationship of the top and bottom jaw (maxilla and mandible) and therefore assess the nature of a patient’s bite. This is particularly useful to plan any orthodontic treatment that may be necessary.
