Publication number: 20230301761Abstract: 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.Type: ApplicationFiled: May 31, 2023Publication date: September 28, 2023Inventors: Ronny Watzke, Christian Frei

Patent number: 10863904Abstract: The invention relates to a recording device (10) comprising a scan head carrier (18) for moving the scan head (20) across a scan area (42) of a cavity, the scan area (42) extending around the scan head (20). A flat or film-like, elastically stretchable material extends between the scan head (20) and the scan area (42), which material can be pressed against the scan area (42) in a balloon (12)-type manner using overpressure. The scan head guide (18) passes through the balloon outlet (16) of the balloon (12) towards the scan head (20). In particular, a control device (44) determines the shape of the cavity (40) against which the material is pressed, from deformation of the material when applying said overpressure. A second extraoral scanning head (43) scans deformations during pressurization of the film-like material.Type: GrantFiled: July 25, 2017Date of Patent: December 15, 2020Assignee: Ivoclar Vivadent AGInventors: Gottfried Rohner, Ronny Watzke, Theresa Senti, Antonio Ferilli

Patent number: 10646311Abstract: 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 (32), in particular in each case on a plastic base. It is characterized by the tooth-colored material (32) of the blank (10) 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 (10 and 32) 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.Type: GrantFiled: March 1, 2016Date of Patent: May 12, 2020Assignee: Ivoclar Vivadent AGInventors: Ronny Watzke, Christian Frei
