| 摘要 |
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 patient's 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.
