What is a 3D X-Ray?
As the name implies, 3D dental x-rays now allow your oral surgeon to get a three dimensional picture of your teeth & jaws. This is done using a new technique called coned beam volumetric tomography.
This latest technology allows hundreds of low-dose x-rays to be taken from all around the patient's head. Sophisticated software then turns this into a 3D image that your oral surgeon can then use to get a good look at what is going on inside your jaws and teeth. This reveals hidden problems or shows details that are not easily seen in older types of X-Rays
Is it a "CAT" Scan?
While similar in principle, the Cone Beam system from Sirona that your dentist has invested in uses about 150 times less radiation than a Medical CT or 'CAT' scan. It is around the same as a traditional film based dental x-ray, less in some cases. Or to put it another way about the same amount that you would get sitting in an airplane for around 30 minutes.
