Abstract
A system for effecting a desired modification in the shape of a pre-existing object to which access is restricted comprises, in accordance with the present invention, a computer, a first data generating device, a second data generating device, a display, an instruction input device and an output device. The first data generating device is operatively connected to the computer for providing the computer with electrically encoded data specifying a three-dimensional surface of the object, while the second data generating device is operatively connected to the computer for providing the computer with electrically encoded data specifying a curvilinear contour of the object. The display is responsive to signals from the computer for displaying a three-dimensional graphic representation of the object in accordance with data from the first data generating device and the second data generating device. The instruction input device operatively serves for instructing the computer to modify the three-dimensional representation of the object on the display and for selecting a modification of the three-dimensional representation which represents a desired object preparation. The output device is operatively coupled to the computer for issuing an output signal to effectuate a limitation in motion of a preparation instrument relative to the object so that the object is provided with the desired object preparation.
