The invention relates to a method for producing a dental prosthesis element (7), according to which the dental prosthesis element (7) is manually reworked. Construction data (17, 17', 17'') relating to the dental prosthesis element to be produced is recorded together with measurement data (7') relating to the dental prosthesis element (7) to be produced and is reproduced on a display (4), the measurement data having been recorded by means of a three-dimensional measurement device (2). The invention also relates to one such method whereby a 3D data record of the tooth situation (14) is reproduced on the display (4) instead of the construction data. The invention further relates to a device for the partial manual treatment of the dental prosthesis element. Said device comprises a three-dimensional measurement device (2), a display (4), and a computer unit (3) comprising means for the correlation and comparison of two data records and for graphically presenting the data generated by the comparison.

Procédés de fabrication d'une prothèse dentaire (7) selon lesquels la prothèse dentaire (7) est retouchée manuellement. Des données de construction (17, 17', 17'') de la prothèse dentaire à fabriquer sont enregistrées en même temps que des données de mesure (7'), relevées à l'aide d'un dispositif de mesure en trois dimensions (2), de la prothèse dentaire (7) à fabriquer et représentées sur un écran (4). La présente invention concerne en outre un procédé, du type susmentionné, selon lequel un ensemble de données en 3D de la situation dentaire (14) est représenté sur l'écran (4), en lieu et place des données de construction. La présente invention concerne encore un dispositif de retouche partiellement manuelle de la prothèse dentaire. Ledit dispositif comporte un dispositif de mesure en trois dimensions (2), un écran (4) et une unité de calcul (3) disposant de moyens pour la mise en relation et la comparaison de deux ensembles de données et pour le traitement graphique des données produites par la comparaison.
