What Is CBCT in Dentistry?

It’s not just a fancy X-ray. It’s a 3D game-changer.

CBCT stands for Cone Beam Computed Tomography. It’s like the MRI of dentistry — only faster and more practical. With one scan, you get a detailed 3D image of the teeth, jaw, nerves, sinuses, and airways. It’s high-res, low-radiation, and ridiculously useful.

What Makes CBCT Different?

Unlike traditional X-rays (which are 2D), CBCT captures an entire volume of anatomy in a single spin. You can view slices from every angle. That means fewer surprises when drilling or placing implants.

What Is CBCT Used For in Dentistry?

• Implant planning: See bone height, width, and density before you place
• Endodontics: Detect accessory canals, root fractures, or missed anatomy
• Orthodontics: Map out jaw relationships, airway space, and root positioning
• Oral surgery: Locate impacted teeth, cysts, and nerve paths
• TMJ diagnosis: Evaluate the joint structure and disc position
• Sleep dentistry: Assess airway dimensions in OSA patients

How Long Does a CBCT Scan Take?

Usually under 30 seconds. The patient stands or sits while the unit rotates. It’s non-invasive and requires no prep in most cases.

Is CBCT Safe?

Yes — especially when used properly. Radiation is higher than standard 2D X-rays but far lower than medical CT scans. Always follow ALARA (As Low As Reasonably Achievable) principles.

What Does a CBCT Machine Cost?

In Australia, CBCT units range from $50,000 to $120,000+. Smaller FOV (field of view) models are cheaper — great for single implants. Larger units are best for full-mouth and airway work.

Our Take

CBCT isn’t for every clinic. But if you do implants, ortho, or complex diagnostics — it’s a powerful tool for accuracy and trust. Think of it as your clinic’s 3D compass.
