Abstract: An image, sound and feeling simulation system for dentistry, comprising a dental handpiece having a drill for drilling a cavity in a tooth, the drill having a drilling end; a first three-dimensional sensor attached to the dental handpiece, the first three-dimensional sensor providing the system with position and orientation in space of at least the drill; and a data processing and display unit for simulating of at least the drilling end of the drill. The system further comprising means to control the flow of compressed air operating the drill and thus to control the rotation of the drill to imitate the sound and hand-feeling associated when drilling through tooth layers of different hardness.
