A one-piece or multi-piece prosthesis blank for manufacturing a dental prosthesis. The blank is constructed from a gum-colored material and a tooth-colored material. It is characterized by being connected to each other at connecting surfaces, having an interface between the gum-colored and tooth-colored materials. This interface, when viewed along the connecting surfaces has an undulating shape and viewed in the vestibular direction has a radial shape. In order to finish the dental prosthesis, a CAD/CAM device determines the exact course of a gingival line, based on patient-specific data, and produces the prosthesis.

Blank for producing a dental prosthesis

The invention relates to a method of producing a dental prosthesis from a one-piece or multi-piece prosthesis blank which is constructed from a gum-colored material and a tooth-colored material (), in particular in each case on a plastic base. It is characterized by being connected to each other at connecting surfaces, having an interface between the gum-colored and tooth-colored materials. This interface, when viewed along the connecting surfaces has an undulating shape and viewed in the vestibular direction has a radial shape. In order to finish the dental prosthesis, a CAD/CAM device determines the exact course of a gingival line, based on patient-specific data, and produces the prosthesis.

Method of producing a dental prosthesis

The invention relates to a denture, made of teeth, in particular prefabricated teeth, and of a denture base made of a gingival material, comprising cavities for teeth in which cavities for the teeth are mounted, in particular attached by bonding, characterized in that the denture base () is produced by a CAD/CAM process forming the cavities () for the teeth (), and in that cervical areas () of the teeth () extending through the basal surface () of the denture base () are removed, in particular abraded or milled.

Blank holder

The invention relates to a dental prosthesis, produced from a one-piece or two-piece prosthesis blank which is constructed from a gum-colored material and a tooth-colored material (), in particular in each case on a plastic base. It is characterized by the tooth-colored material () of the blank () which, in the blank state, has a size larger than a human dental arch. It is in particular at least 8 cm wide. The invention is further characterized in that the gum-colored and the tooth-colored material (and) are intensively connected to each other, whether by one-piece production, by adhesive bonding or by polymerization, in particular by polymerization. Viewed along the course of the dental arch, the interface between the materials has an undulating shape and, viewed in the vestibular direction, has a radial shape.

Denture and method of producing a denture

The invention relates to an occlusion determination device (), with a bite frame () and an extraoral bracket () which are connected together, wherein a reference element has at least one vertical leg () and at least one horizontal leg () and is connected by way of a bipupillar linkage () to the bite frame (). The reference element is designed as an extraoral bracket () which extends vertically offset from the bite frame ().

Occlusion determination device

The invention relates to a tooth made of ceramics, a composite or plastic, which is produced in a mold, said tooth having a basal surface () that comprises a trough (). The especially elliptical or circular trough () is adapted to the basal surface () and has a trough edge () which extends at least partially in an angle of more than 45 degrees, in particular more than 60 degrees or 70 degrees, with respect to the adjacent basal surface ().
