Radiology - Denta Scan

What is a CT Dentascan?
A CT Dentascan is a specialised type of CT scan that uses special software to construct unique 3D pictures of your jaws and surrounding tissues. This is particularly useful to assess the position of impacted teeth or plan dental implants, as accurate and precise measurements can be made from Dentascan images. Dental CT scans have many other applications and greatly assist patients dentists or specialists in providing the best care possible.
An appointment is required for this service to ensure patients are seen promptly and efficiently. Queensland X-Ray offers fast, high resolution, low-dose scanning on new 64-slice scanners in many locations, and has recently installed a 256-slice scanner in Toowoomba.

What should patients expect when they arrive for their appointment?
During a CT Dentascan, patients will lie down on a special table that will move into the scanner, which typically looks like a large donut. Dentists or specialists may sometimes provide patients with a special plate to wear during the scan. The table will move into the machine for the scan, and will then slide back out once the scan is complete. The Radiographer will then reconstruct 3D images from the scan according to instructions provided by the dentist or specialist.
It is important to follow any instructions closely, and remain still. Occasionally a Dentascan may need to be repeated if the position is not exact, or if there is some movement during the scan.

How long does it take?
The procedure is very brief (about 15 minutes or less) and is painless and simple. It is very important to follow all instructions and hold absolutely still once positioned. Patients images or scan are interpreted by a Dental Radiologist (a dentist with special training in dental imaging). Patients can either wait for results or alternative arrangements can be made to collect them at a later stage. Please collect images and results before returning to refferer.

Is there any special preparation?
There is no special preparation required and there are no after effects following the scan. Once you are at the practice, patients will be asked to remove any jewellery or metallic items from the head and neck region, including any piercings, hair accessories, dentures and plates, as these often interfere with x-ray image formation. Patients will not be required to change into a gown. Dentists or specialists may provide a special plate to wear during the scan - please bring this to the appointment.

Who can refer for a CT Dentascan?
Patients are eligible for a Medicare rebate if referred by a dental specialist or a doctor. Patients who are referred by a general dentist will be required to pay a small fee.
