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

System for the manufacture of a dental prosthesis

A dental prosthesis is provided, manufactured from a one-piece or multi-piece prosthesis blank which is composed of a gum-colored material () and a tooth-colored material (), especially each one being based on plastic material. The tooth-colored material () of the blank () has a diameter or a width of more than 5 cm and especially a substantially flat cylindrical shape with a diameter/height ratio of more than 2:1, preferably more than 3:1. The gum-colored and tooth-colored materials () are bonded together by bonding, polymerization and/or integral production. The boundary () between the materials, as viewed in the direction of the dental arch course, is wave-shaped with alternating grooves and ribs (), and in the region of the anterior arch in the vestibular direction—is of radiant shape.

Dental prosthesis blank

Monochromatic dental shaped body, which has an opacity of from 70 to 78%, and a process for its production.

Monochromatic dental shaped article and blank for making dental restorations

A method for producing a prosthesis or partial prosthesis based on digital data, using multiple teeth present in a dental arch () and a prosthesis base to be produced. The prosthesis base is rough-milled by a milling tool, i.e. is milled in a first step, and the prosthesis base present as a semi-finished product, in particular in regions of the prosthesis base on which the teeth and the prosthesis base abut against each another and/or are to be bonded to each other, is partially milled, i.e. is milled in a second step, by a different milling tool, thereby being brought to a target height which corresponds to the desired bonding gap between the prosthesis base and the tooth or dental arch ().

Method for producing a prosthesis or partial 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.

Denture as well as method of producing a denture

Milling blank

Method and system for the construction of a total dental prosthesis, wherein the shapes of the upper and lower jaw bases taken in the plastic material are digitized and stored as a digital prosthesis model in a data-processing device, and the upper and lower jaw prosthesis bases are produced from dental materials according to the digital prosthesis model by ablative or constructive methods.

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 ().
