When starting orthodontic treatment, you may hear your dentist or orthodontist mention a "ceph X-ray" or cephalometric radiograph.
But what exactly is it, and why is it so important for braces, aligners, and jaw treatments?
What Is a Cephalometric X-Ray?
A cephalometric X-ray is a special type of 2D dental radiograph that captures the entire side view of your face, including your teeth, jaws, and airway. Unlike a standard panoramic X-ray, which shows the teeth in a wide arc, a ceph scan shows the relationship between your teeth, jawbones, and skull.
Why Orthodontists Use Cephalometric X-Rays
Ceph X-rays provide essential diagnostic information for:
- Braces and aligners — determining how your teeth should move
- Jaw growth — monitoring developing patients and planning jaw corrections
- Airway evaluation — checking for airway obstruction or narrow passages
- Facial proportions — ensuring treatment improves both function and aesthetics
This information helps orthodontists create personalized treatment plans for predictable and successful outcomes.
Ceph Tracings and Digital Analysis
One of the most important uses of ceph imaging is cephalometric tracing. Specialized software outlines skeletal and dental structures on the X-ray, creating reference points and measurements. Orthodontists then use these tracings to analyze bite relationships, jaw angles, and airway space.
Safety and Radiation Dose
A ceph X-ray involves very low radiation — similar to a few days of background exposure. Modern digital equipment keeps doses minimal while providing clear, high-resolution images.
What to Expect During a Ceph X-Ray
- Quick: scan takes less than a minute
- Comfortable: you'll stand still while the machine rotates
- No referral needed for orthodontic screening, but specialists often prescribe it
- Same-day delivery: files can be shared with your orthodontist immediately
