Dental oven

The present invention relates to a dental blank, in particular a parallelepipedal block, having an upper surface and a lower surface, which is composed of a flesh-coloured material and a tooth-coloured material. The flesh-coloured material and the tooth-coloured material are bonded together. The interface between the materials with elevations and depressions formed in or at the interface extends through an optionally curved plane, which plane is parallel to or oblique to at least a portion of the surfaces of the blank.

Dental block forming a blank for a partial prosthesis, dental partial prosthesis and method of manufacturing a dental partial prosthesis

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.

Dental blank, dental partial prosthesis and method of manufacturing a dental partial prosthesis

Dental device

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 recording device () comprising a scan head carrier () for moving the scan head () across a scan area () of a cavity, the scan area () extending around the scan head (). The scan head guide () passes through the cavity towards the scan head (). In particular, a control device () determines the shape of the cavity (). A second extraoral scanning head () scans extraoral areas.

Recording device

The invention relates to a recording device () comprising a scan head carrier () for moving the scan head () across a scan area () of a cavity, the scan area () extending around the scan head (). A flat or film-like, elastically stretchable material extends between the scan head () and the scan area (), which material can be pressed against the scan area () in a balloon ()-type manner using overpressure. The scan head guide () passes through the balloon outlet () of the balloon () towards the scan head (). In particular, a control device () determines the shape of the cavity () against which the material is pressed, from deformation of the material when applying said overpressure. A second extraoral scanning head () scans deformations during pressurization of the film-like material.

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.

Denture as well as method of producing a denture

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.

Dental prosthesis

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 ().
