A composite, three-dimensionally stable facing material for adding aesthetic features to a denture base. The composite may be a flexible, flat strip of material capable of being molded to gingival surfaces of the denture base and retained on the denture base. The strip is capable of being trimmed and then cured to a hardened state. Fibers and/or other characterization may be added for increasing realism of the denture gingival surfaces.

A dental restoration device includes a sleeve having an exterior surface and an interior pocket that is at least partially filled with a dental cement, and a crown having an exterior surface and an interior surface that is mated to the exterior surface of the crown and bonded thereto by an adhesive disposed between the exterior surface of the sleeve and the interior surface of the crown.

Antimicrobial polymer composite materials are disclosed that are suitable for making oral devices used in dental applications, such as denture bases. Acrylic resin composite materials comprising antimicrobial polymers and antimicrobial fillers provide reduction in common oral microorganisms after long-term aging, with reduced release rate of antimicrobial agents from the composite material. Antimicrobial polymers are prepared from compositions comprising acrylate and/or methacrylate monomers and polymerizable quaternary ammonium silicon-containing compounds.

Denture duplicating methods and systems are described that include a controller configured to scan a mold of a denture for a wearer using a scanner, create a denture specifications file associated with the mold of the denture, store the denture specifications file in non-transitory computer readable memory, upon request, retrieve the denture specifications file and load it into a milling design software program to generate a replacement denture platform design, and instruct a communicatively coupled three-dimensional printer to perform a print operation resulting in a replacement denture platform based in part on the replacement denture platform design before the replacement denture platform and milled teeth can then be sent to the wearer.

A dental prosthesis is provided, manufactured from a monobloc or multibloc prosthesis blank (10), which is composed of a gum-colored material (14) and a tooth-colored material (12), which materials (12, 14) are bonded to each other by bonding, polymerization and/or one-piece manufacture. The boundary surface (16) between the materials is wave-shaped comprising alternating grooves (22) and ribs (24) in the course of the dental arch, and radial in an oral-vestibular direction in the region of the anterior teeth (33) to be created. The boundary surface (16), at least in the region of the molars (26)—again as viewed in the oral vestibular direction—has parallel grooves (22) and ribs (24) forming troughs and crests of the waveform, or grooves (22) and ribs (24) such that they extend in deviation from parallel by at most 10 degrees, in particular at most 5 degrees, at least in the region of the molars (26).

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 (32), 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.

A unique CAD subtract body intended to create a design of a mating surface for a veneering overlay and a dental implant framework wherein the unique CAD subtract body is derived from a diagnostic wax-up surface model. The diagnostic wax-up surface model is created from at least one of scanning a diagnostic wax up or denture tooth set up, CAD models in a virtual set up, an intraoral scan of a diagnostic wax up or denture tooth set up taken in a patient's mouth, a CT scan or series of CT scans of a patient's mouth, a CT scan or series of CT scans with the use of a radiographic stent in a patient's mouth, and wherein the unique CAD subtract body can be used to create the tool path for the manufacturing of the veneering overlay and allows for the fabrication of a dental implant from at least one of a metallic material, a ceramic material, an acrylic material, a biocompatible material.
