A method for preparing a dental restoration with at least one rotating material removing tool (2) is presented, the method comprising the steps of providing a dental material piece (1) from which the dental restoration is to be prepared, providing an initial cavity (C) in the material dental piece (1), and removing material outside the initial cavity (C) by moving the tool (2) essentially in a plane perpendicular to the rotational axis (R) of the tool (2). In hard, brittle dental restoration materials, risks of material failure, excessive tool wear, and tool failure are reduced, and higher processing speeds are made possible.

L'invention concerne un procédé permettant de préparer une restauration dentaire à l'aide d'au moins un outil (2) d'enlèvement de matériau tournant, qui consiste à fournir une pièce de matériau dentaire (1) à partir de laquelle on prépare la restauration dentaire, à fournir une cavité initiale (C) dans la pièce de matériau dentaire (1), et enlever le matériau hors de la cavité initiale (C) par déplacement de l'outil (2) dans un plan perpendiculaire à l'axe de rotation (R) de l'outil (2). En ce qui concerne les matériaux de restauration dentaire durs et fragiles, les risques de défaillance du matériau, d'usure excessive et de défaillance de l'outil sont réduits, ce qui rend possible des vitesses d'exécution plus élevées.
