3D imaging is now for dentistry (at selected imaging centers). It has real significant uses for implants and impacted teeth. It can also be helpful in diagnosing otherwise difficult situations with sinuses and jaw joint problems. Here a is new use – veterinary dentistry: zoo finds high-tech tools to see aardvarks teeth!
As you can imagine this technology is very expensive. The scanner that the Loyola Medical Center gave to the zoo was worth a million dollars new. Human dental 3D imaging machines cost a couple hundred thousand dollars, but an actual scan runs only about $600 currently. When needed it is definitely worth it.
