Computed tomography, or CT greatly facilitates 3D viewing the internal morphology of soft tissue and skeletal structures. Units will soon begin to appear in dental office for use in oral surgery, orthodontics, implants
Orthodontics uses "Orthocad" system which creates 3D models from impressions. Used for diagnosis and determining bracket alignment. Store 3D models in virtual reality.

Use of 3D virtual reality simulators for training e.g. DentSim™.
Use of 3D virtual reality simulators which allow you to feel what is on the screen. Being developed at UIC Dental School.
All of Dentistry heading into 3D graphics.
