CT Scan

What is a dental CT scan?

A dental CT scanner uses x-rays and a computer 3D cross sectional images of the jaws and teeth. It is a compact, faster and safer version of the regular CT scanner. Through the use of a cone shaped x-ray beam, the size of the scanner, radiation dosage and time needed for scanning are all reduced. The machine moves around your head in a circular motion.

 

How can I prepare for the dental CT scan?

Before your CT scan you will be asked to remove glasses, dentures, hearing aids, earrings, tongue studs, necklaces, hair clips and any other metal accessories that may affect the scan. This is not an examination that requires any injections or special preparations beforehand. If you are having a scan for dental implant planning you may be asked by your dentist to bring a localisation stent with you. This is a special ‘plate’ which you will wear rather like a denture, containing markers to guide our x-ray examination. You will only need to wear this during the scan.

 

Please inform your dentist if there’s a possibility you may be pregnant.

 

Will I feel any pain?

This procedure is not painful, but you will need to remain still for the duration of the scan. The CT scan only takes 18 seconds.

 

What are some typical uses of the procedure?

CT Scans are commonly used for treatment planning of orthodontic issues. It is also carried out for more complex cases that involve:

  • Surgical planning for impacted teeth

  • Diagnosing temporomandibular joint disorder (TMJ)

  • Accurate placement of dental implants

  • Evaluation of the jaw, sinuses, nerve canals and nasal cavity, identifying, measuring and treating jaw tumours

  • Determining bone structure and tooth orientation

  • Discovering the origin of pain or pathology

  • Cephalometric analysis

  • Reconstructive surgery

 

How does the procedure work?

During a CT Scan examination, the C-arm or gantry rotates around the head in a complete 360-degree rotation while capturing multiple images from various angles that are reconstructed to create a single 3D appearance.

The x-ray source and detector are seated on opposite sides of the revolving C-arm or gantry and rotate in unison. In one simple rotation, the detector can generate anywhere between 150 to 200 high resolution 2D images, which are then digitally combined to form a 3D image that can provide your dentist with beneficial information about your oral health.

 

How is the procedure performed?

You will be asked to stand very still whilst the x-ray source and detector revolves around you for a 360 degree rotation or less. This normally takes 18 seconds for a full mouth x-ray, where the entire mouth and dental structures are captured.

 

What happens after I have had the CT scan?

After the examination you will be able to go home straight away. The scan and report will be sent through to the dentist who has referred you to us for the examination. We can also give you the CT scan to take along.
