Cephalometric X-Ray

Most people have heard of an x-ray, but what exactly is a cephalometric x-ray? How is it different from other types of imaging? We’re here to guide you through this useful technology and spell out when and why it’s so helpful.

Cephalometric Analysis is an X-ray similar to a panoramic X-ray, in that it has the capability of capturing a full view of your skull and neck. A difference is that it is captured using a side-to-side sweeping motion, instead of the full 360 degree non-stop motion used in panoramic X-rays.

Ceph X-rays are generally used to diagnose developmental concerns involving the head, neck and jaw that a dentist, orthodontist or surgeon believes may be interfering with proper facial and oral development.

They are commonly used to:

- Explore possible TMJ concerns
- Assess the reasons behind excessive tooth misalignment – particularly in cases where an overbite or underbite is present
- Diagnose suspected tooth and/or jaw fractures
- Obtain precise measurement of teeth including their root structures
- Or, plan for orthodontic work

Cephalometric Analysis is particularly useful in understanding the complexities of overbites and underbites, because the position or underdevelopment of the jaw plays a significant role with these concerns. Orthodontists find them invaluable in the administration of orthodontic work because they need to evaluate the movement of the teeth, and sometimes the jaw, over the course of several years. The full picture a Ceph enables them to gauge the success of the work, and the adaptation of the body to treatment.

Like other types of X-ray tools, Cephs can be performed as either digital or film scans depending on availability within your dentist’s office, or your preference.
