Abstract: A method for producing a dentist tool includes simulation of predetermined horizontal, vertical, and tilt movements to be followed by a cutting tool to remove a predetermined part of tooth structure for further treatment of a tooth. An overlay is determined to fit the tooth by determining a first guiding edge within the overlay corresponding to the predetermined movements and determining a second guiding edge within the overlay spaced apart from the first guiding edge and corresponding to the predetermined movements. The first and second guiding edges are provided to contact the cutting tool so as to guide horizontal, vertical, and tilt movements of the cutting tool such that the cutting tool follows the predetermined horizontal, vertical, and tilt movements for removal of the predetermined part of tooth structure. The determined overlay is produced with the first and second guiding edges and such that it fits the tooth.

Abstract: Method for producing a dentist tool formed by an overlay to be used by a dentist in removing tooth structure, said method comprising the steps of: acquiring three-dimensional data relating to a shape of a tooth and at least a part of a neighbouring tooth; processing said three-dimensional data with a computer so as to determine an overlay fitting said tooth and fitting at least said part of said neighbouring tooth; further processing said three-dimensional data with said computer so as to determine a predetermined part of tooth structure to be removed from said tooth so as to prepare said tooth for further treatment; determining at least two guiding edges of which a first and a second guiding edge are spaced apart from each other by a distance d of at least 0.
