The present invention relates to a method and a device for manufacturing a provisional or a final dental prosthesis (9) for a dental implant, comprising the following steps: - receiving 3D surface scan data (1) from a scanning of a surface of a patients oral cavity in an area of interest for a treatment - receiving volume scan data (2) of a respective upper or lower jaw - registering the 3D surface scan data (1) with the volume scan data (2), obtaining virtual 3D model data - selecting a virtual implant and virtually positioning the virtual implant within first virtual data (3) representing the virtual 3D model data, obtaining second virtual data (4) - selecting and associating a virtual scanbody (VS) with the top of the virtual implant within the second virtual data (4), obtaining third virtual data (5) - virtually removing the virtual implant and the volume scan data (2) from the third virtual data (5) and extracting information relative to the virtual scanbody (VS) and the 3D scan surface, such as to obtain fourth virtual data (6) representing merged information of the 3D surface scan data (1) and the virtual scanbody (VS) - providing the fourth virtual data (6) for the design of the provisional or the final prosthesis (9), wherein the prosthesis (9) can be designed based on information incorporated by the virtual scanbody (VS) by use of a suitable CAD software.La présente invention concerne un procédé et un dispositif pour la fabrication dune prothèse dentaire provisoire ou finale (9) pour un implant dentaire, comprenant les étapes suivantes : la réception de données de balayage de surface 3D (1) à partir dun balayage dune surface de la cavité buccale dun patient dans une région dintérêt pour un traitement la réception de données de balayage de volume (2) dune mâchoire supérieure ou inférieure respective le calage des données de balayage de surface 3D (1) avec les données de balayage de volume (2), permettant dobtenir des données de modèle 3D virtuel la sélec
