A dental device is described that comprises a monolithic support structure for use in implant-supported dental restoration applications for partially or fully edentulous patients. The monolithic support structure comprises a unitary support body with one or more teeth projections projecting from the support body, and at least one support region providing a framework for integrating discrete artificial teeth adjacent the teeth projections. An implant-supported dental device is also provided that comprises the monolithic support structure, one or more artificial teeth, and a gingival region comprised of a formable material that secures artificial teeth within the framework of the monolithic support structure.

A dental device is improved in its ability to produce hydroxyl apatite by having a layer of mineral trioxide aggregate (MTA) deposited thereon. A tile of MTA is prepared, heat treated and sintered to produce a micronized tile of MTA that can then be deposited by physical vapor depositions, hot isostatic pressing, molding or other conventional technique.

A virtual three-dimensional model for use in developing a patient-specific prosthesis to be coupled to an implant installed in a mouth of a patient includes one or more virtual teeth, virtual gingival tissue, and a floating virtual proxy abutment. The virtual gingival tissue includes a virtual gingival aperture leading to a location for a virtual implant. The floating virtual proxy abutment is positioned relative to the virtual gingival aperture and is virtually detached from the rest of the virtual three-dimensional model. The floating virtual proxy abutment has known characteristics for determining a location and an orientation for the patient-specific prosthesis to be attached to the implant.

A blank material to be cut for dentistry includes: Co as a main component; Cr at a ratio equal to or higher than 26 mass % and equal to or less than 35 mass %; Mo at a ratio equal to or higher than 5 mass % and equal to or less than 12 mass %; Si at a ratio equal to or higher than 0.3 mass % and equal to or less than 2.0 mass %; and N at a ratio equal to or higher than 0.09 mass % and equal to or less than 0.5 mass %. The blank material is formed of a sintered body of a metal powder.

The present invention relates to a dental prosthesis molding block for producing a dental prosthesis part. The block comprises an inner material that is at least partially surrounded by an outer material, the hardness of which differs from the hardness of the inner material. The inner material forms part of a first surface of the dental prosthesis molding block. The invention further relates to a method for producing a dental prosthesis part. In said method, a dental prosthesis molding block is provided, and the dental prosthesis part is produced by removing material from the dental prosthesis molding block using a CAD/CAM process. In doing so, a pin having a self-tapping external screw thread is created.
