What type of CT scan used to see a 3D imaging of the mandible and chin implant?

In my office, we assess the position of a chin implant with a cone beam CT. The scan takes 30 seconds and requires limited radiation exposure. The implant shows up in 3-D nicely with this scan. 

A CT scan of the mandible is performed in 3 dimensions and is usually reformatted by the computer.  There is really no reason to even get a CAT scan to look at the placement of the chin implant.  A physical examination is enough to make the determination if the implant is out of place and needs to be removed, or replaced. There is no sense in exposing the patient to unnecessary radiation

It is a high resolution 3D CT scan of the mandible. That will show the position of a chin implant on the bone.

if you want to look at a chin implant placement more cheaply you can do it with 2 plain films.
