Cone Beam CT is a relatively new technique, which is mainly used to assess the jaws and teeth. Its main advantage compared to OPGs and other dental x-rays is that it provides three-dimensional imaging (similar to conventional CT, but with a lower radiation dose). Perth Radiological Clinic uses the Cone Beam CT system, which provides high definition, three dimensional imaging to complement our other dental imaging services including OPGs and conventional CT scanning. Cone Beam CT offers 3-D evaluation of dental anatomy and pathology: for example impacted teeth, pre-implant assessment, orthodontic assessment, and assessment for jaw and face surgery.
Medicare rebates apply for Medicare eligible patients if they are referred by their dental specialist or medical doctor. Medicare rebates do not apply to referrals from general dentists.
The procedure is similar to having an OPG. The examination is painless. You will be asked to sit with your chin resting on a small support shelf to provide accurate positioning. The scanner will move around your head and from this the processer will build and store a three-dimensional image that the radiologist will review and assess.
The three-dimensional image data will also be provided on a disc to the dentist or specialist who referred you, and can be used with other software, for example for implant planning.
