With fast scanning times, low radiation doses and a range of fields of view and resolutions, the new Cone Beam Computed Tomography (CBCT) scanner at Elmsleigh House Dental Clinic offers exceptional insight for treatments such as dental implants, root canal treatment, orthodontics and oral surgery.

How does it work?

An x-ray beam in the shape of a cone is moved around the patient to produce a large number of high-quality images. In a single rotation, the detector can generate anywhere between 150 to 200 high-resolution two-dimensional images, which are then digitally combined to form a three-dimensional image that can provide your dentist or oral surgeon with valuable information about your oral and craniofacial health. This new technology uses ultra-low-dose radiation to obtain exceptional images.

What happens during a CBCT scan? 

Prior to the examination, you may be asked to remove anything that may interfere with the imaging, including metal objects, such as jewellery, glasses, hairpins and hearing aids.

Women should always inform their dentist or oral surgeon if they are pregnant. 

Your dentist will position you correctly and you will be asked to remain very still while the x-ray source and detector revolve around you for a 360-degree rotation or less. This typically can take between 20 to 40 seconds for a complete volume or just 10 seconds for a scan that focuses on a specific area of your jaw.  

Your dentist will show you the three-dimensional images, discuss the findings and make any recommendations on treatment based on these results.

What are the benefits of CBCT?

• The focused x-ray beam reduces scatter radiation, resulting in better image quality.
• A single scan produces a wide variety of views and angles that can be manipulated to provide a more complete evaluation.
• CBCT scans provide more information than conventional dental x-ray, allowing for more precise treatment planning.
• CT scanning is painless, non-invasive and accurate.
• A major advantage of CBCT is its ability to image bone and soft tissue at the same time.
• No radiation remains in a patient's body after a CBCT examination.
• X-rays used in CBCT scans should have no immediate side effects.
