Title
(EN) A METHOD FOR A DENTAL RESTORATION
(FR) PROCEDE DE RESTAURATION DENTAIRE
Abstract
(EN)
The present invention relates to a method for producing a dental restoration of at least part of at least one tooth. The method comprises measuring the surface of a preparation replica (1) of a preparation, for which the dental restoration is intended, and storing information about the topology of the preparation replica (1) in a data storage means (3), and creating a computer model (4) of the dental restoration, whereby at least some of the information stored in the previous step is used and/or user inputs from a computer operator is registered. At least one tool path is generated for the control of a machining equipment (5), using the computer model (4), and a restoration replica (6) is machined in a restoration replica material, using the at least one tool path. Finally a mould (7) is formed, using the restoration replica (6), and the dental restoration is cast, using the mould (7).
(FR)
La présente invention concerne un procédé de restauration dentaire d'au moins une dent. Ce procédé consiste : - à mesurer la surface d'une réplique (1) d'une préparation, pour laquelle la restauration dentaire est destinée, et à stocker les informations relatives à la topologie de la réplique de préparation (1) dans un moyen de stockage de données (3), et à créer un modèle informatique (4) de la restauration dentaire. Au moins certaines informations stockées à l'étape précédente sont utilisées et/ou les entrées utilisateur d'un opérateur d'ordinateur sont enregistrées. Au moins une trajectoire d'outil est générée pour le contrôle d'un équipement d'usinage (5) à l'aide du modèle informatique (4), et une réplique de restauration (6) est usinée dans un matériau de réplique de restauration, à l'aide du ou des trajectoire(s) d'outil. Finalement, on réalise un moule (7) à l'aide de la réplique de restauration (6) et on coule dans ce moule (7) la restauration dentaire.
