CBCT scan in orthodontics in Dubai — low-dose 3D imaging of jaws, airway and TMJ

Key facts

• CBCT gives true 3D measurements of jaws, roots, airway and joints
• Used when it will change the plan, not routinely
• Dose is much lower than a hospital medical CT
• Essential for MARPE suture and miniscrew planning
• Findings are explained and built into a written plan

What a CBCT scan is

Cone-beam CT is a type of 3D X-ray designed for the head and face. The scanner rotates once around your head while you stand or sit still, capturing data that is reconstructed into a three-dimensional model. The scanning itself usually takes well under a minute, and nothing enters the mouth. Unlike a panoramic or cephalometric X-ray, which flattens structures onto a single image, CBCT lets the orthodontist view the jaws, tooth roots, palate, airway and jaw joints from any angle and measure them in true dimensions. The field of view can be limited to the area of interest, which helps keep the radiation dose as low as reasonably achievable.

When CBCT is justified in orthodontics

CBCT is not needed for every patient. Simple alignment cases are usually planned with clinical examination, photographs, digital scans and standard 2D X-rays. A 3D scan is considered when it is likely to change the treatment plan, for example: locating impacted or ectopic teeth such as canines and checking whether they are damaging neighbouring roots; assessing root position and bone thickness before significant tooth movement; evaluating the airway and nasal floor in patients with breathing concerns; examining the temporomandibular joints when there is pain or clicking; planning skeletal anchorage (TADs); and assessing jaw relationships where surgery may be considered. Dr. Moaiyad Pacha explains why a scan is recommended before it is taken.

Radiation in context

Every X-ray involves some radiation, so the guiding principle is to take a scan only when its benefit clearly outweighs the small risk. A dental CBCT generally delivers a much lower dose than a conventional hospital medical CT of the head, and a limited-field orthodontic CBCT is often comparable to a short series of standard dental X-rays, depending on the settings used. Using a scan only where it is justified, limiting the field of view and avoiding repeats all reduce exposure. Children are more sensitive to radiation, so extra care is taken in deciding when imaging is needed. If you are pregnant or might be, tell the clinic before any X-ray.

How CBCT plans MARPE and airway treatment

For miniscrew-assisted rapid palatal expansion (MARPE), CBCT is central to planning. It shows the maturity and shape of the mid-palatal suture, the thickness of the palatal bone and the safest positions for the miniscrews, so the appliance can be designed to engage the strongest bone. Suitability for MARPE depends on this anatomy rather than age alone. The same scan can show the nasal cavity and upper airway, helping Dr. Moaiyad Pacha discuss whether expansion is likely to contribute to nasal breathing in that particular patient, while being clear that MARPE on its own does not treat sleep apnoea. Follow-up imaging is taken only if it will guide decisions.

What happens at Manhal and what you receive

At Manhal Medical Center in Dubai, Dr. Moaiyad Pacha — a consultant orthodontist with a clinical PhD from Queen Mary University of London and RCS orthodontic fellowship and membership — reviews whether a CBCT is needed at your consultation. If it is, the scan findings are explained to you in plain language, combined with your digital scan and clinical findings, and built into a written treatment plan. Findings outside orthodontics are flagged so you can follow them up with the appropriate doctor. Because Dr. Pacha divides his time between London and Dubai, contact the clinic for his Dubai dates.

It is never too late to straighten teeth. Adult orthodontics often works alongside implants, veneers or gum treatment, and discreet appliances fit professional life.
