Cone Beam CT (CBCT)
A Cone Beam CT is a series of images which is used to create a three dimensional image of the jaw, teeth and temporomandibular joints.
Cone Beam CT is used to:

Your appointment and preparation
A referral and an appointment are required for a Cone Beam CT examination.
There is no preparation for a Cone Beam CT.
What can I expect during my Cone Beam CT?
You will be asked to remove any jewellery, hair ties or metal objects in the region of the head and face before the examination.
The radiographer will position you in the specially designed Cone Beam CT machine. You will be asked to face the machine, rest your chin on a rest, and to bite gently on a bite piece to separate your teeth. Your head will be held still and in the correct position in an adjustable head holder. Sometimes your specialist will provide you with a special plate to wear during your scan. Once you are in position, the Cone Beam machine will rotate around your head to collect a series of data from which 3D reconstructions of your jaw and teeth can be produced. The examination takes only a few seconds.
