The cephalometric X-ray is a specialized imaging tool that allows your trusted dentist to capture a detailed radiograph of the side profile of your face. Unlike standard X-rays, these images reveal the teeth, jawbone, and soft tissues in ways you can’t see just by looking. Cephalometric X-rays are extraoral, so there’s no need to place any film or plates inside your mouth. They also show areas like the nasal passages and sinuses, which bitewing X-rays don’t capture.
Cephalometric X-rays are typically taken using a panoramic X-ray machine that’s modified with a special cephalometric film holder attached to a mechanical arm. The X-ray receptor is exposed to a controlled amount of ionizing radiation, providing clear pictures of your entire oral structure while keeping radiation exposure low.

- Show the side profile of your face clearly.
- Reveal the relationship between the jaw and cheekbone.
- Help diagnose malocclusions or “bad bites.”
- Allow precise measurements of teeth and jaw structures.
- Detect fractures or injuries to teeth and jawbone.
- Play a key role in orthodontic treatment planning.
How are cephalometric X-rays taken?
These X-rays are painless and straightforward. You’ll be asked to position your head between the rotating mechanical arm and the film holder, which move around you to capture detailed images of your face, mouth, and teeth. Proper positioning is important for clear, sharp images, which are often magnified up to 30% to help spot any signs of decay, injury, or disease.
After the images are taken, your dentist will have a full side-profile view of your head. This helps with planning orthodontic treatments like braces and evaluating how they may affect your facial profile. Cephalometric X-rays are also useful when preparing for dental implants by providing exact measurements.
If you have any questions or concerns about cephalometric X-rays, don’t hesitate to ask your experienced dentist at Aesthetic Family Dentistry.
