Computed tomography (CT) is a method of body imaging in which a
thin x-ray beam rotates around the patient. Small detectors
measure the amount of x-rays that make it through the particular
area of interest. The scan is complete within 20-40 seconds.
Radiation exposure for these scans is very minimal. You will not
have to refrain from eating or drinking. The only thing you will have
to do is remove any metal you may be wearing, which includes
rings, necklaces, metal partial etc. It's as simple as you just sitting
there.
The purpose for the CT Scan is that the doctor may see your bone
level. We then produce a duplicate of your jaw. With this duplicate,
the doctor is able to see how much bone you have and where the
best area is to place an implant or if bone 
needs to be added. It
makes your procedure a lot more comfortable.
