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.

Advantages :

One of the biggest benefits of the lateral cephalometric x-ray is the advantage of “natural” head positioning. The lateral cephalometric x-ray uses a line known as the true vertical as an external reference point. Because the true vertical is generated by gravity and the head is in its normal positioning, a doctor or orthodontist can study the head as it would be positioned without any additional altering. This is why many refer to the lateral cephalometric x-ray as revealing the “natural” head positioning through the use of the true vertical.

Why take a lateral cephalometric x-ray?

Like other types of cephalometric x-rays, the lateral cephalometric x-ray is very helpful in dental and orthodontic treatment planning.

It can be used in many stages of treatment to determine what is the next best stage. However, the lateral cephalometric x-ray in particular is used by dentists and orthodontists because it can provide specific images of the mandible, or jaw, and its relationship to the maxilla, or cheek bone.

This can be useful in many different types of treatment plans, and it may be recommended as an analytical tool by your doctor. The difference between a lateral and horizontal cephalometric x-ray is that a lateral x-ray provide a photo of the side (lateral) view, while a horizontal x-ray provides a view of the top.
