The invention relates to a device and a method for manufacturing a dental prosthesis with which and in which the data records for fabricated teeth are fitted into a virtual model of the oral situation. It is possible to subsequently directly manufacture the denture base or to insert the fabricated teeth in the model.

Device and method for manufacturing dental prosthesis

The aim of the invention is the improvement of an arrangement for the imaging of surface structures of three-dimensional objects, comprising a device for the optical recording of the surface of at least a partial region of the three-dimensional object from different positions, such that the imaging of the object can be carried out with comparatively little complexity with high reproducible accuracy. According to the invention, the arrangement thus comprises a selection circuit (), for the selection of a first image section () and a subsequent image module (), in which at least one further image section () is digitally recorded. A comparator unit () serves to compare the digital patterns () contained in the first () and the at least one further image section () and permits the generation of comparison information on the degree of matching of the digital patterns (), provided to an image processing unit (), for determination of spatial parameters and for the aggregation of the image section () of the object to give an overall image.
