Dental Imaging

OPG

An Orthopantomogram (OPG) is a type of x-ray that examines the lower face, teeth, jaw joints and maxillary sinuses. The teeth are displayed in a long flat line. This x-ray is useful to demonstrate the number of teeth as well as their position and growth, and is particularly useful to assess teeth that have not yet surfaced.

During the examination, the arm of the machine will rotate slowly around your head, but will not come into contact with you. You will be instructed to bite on a small plastic mouthpiece attached to the machine, which keeps the top and bottom teeth separated and helps position the mouth properly in the machine. It is important to remain very still during the scan.

Lateral Cephalogram 

A Lateral Cephalogram (or Lat Ceph) is an x-ray taken of the side of the face with very precise positioning, so that various measurements can be made to determine the current and future relationship of the top and bottom jaw (maxilla and mandible) and therefore assess the nature of your bite. This is particularly useful to plan any orthodontic treatment that may be necessary.  

During the examination, your head will be positioned in calipers that fit into the ears like earphones. A measuring device will be placed at the bridge of the nose.  

Cone Beam CT

A Cone Beam CT is a form of 3D dental imaging. During the examination, the machine will rotate around your head and the data is then reconstructed into a 3D image. Cone Beam examinations allow dentists and doctors to plan surgery for impacted teeth; review dental pathology and trauma; plan dental implants; assess TMJ disorders; evaluate the jaw, sinuses, nerve canals and nasal cavity; and plan endodontic and orthodontic treatment.

You will be instructed to bite on a small plastic mouthpiece attached to the machine, which keeps the top and bottom teeth separated and helps position the mouth properly in the machine. Alternatively, your dentist or specialist may provide you with a special plate to wear during the scan. It is important to remain very still during the scan.

CT Dentascan

Dentascan is a 3D scan which uses advanced software to construct unique 3D pictures of your jaw and surrounding tissues. This is useful to assess the position of impacted teeth, or plan dental implants, as accurate and precise measurements can be made from Dentascan images.

Your dentist or specialist may provide you with a special plate to bite down on during the scan. The table will move your head into the machine for the scan, and will then slide back out once the scan is complete.

PREPARATION

No special preparation is required for dental imaging. Patients will be asked to remove jewellery and metallic items from the head and neck region.

AFTER YOUR EXAMINATION

After your examination, you will be able to resume normal activities.
